J-HangarSpace was again fortunate to be able to join an organized group visit that provided a rare opportunity to look behind the scenes/hangar doors at two long-term Tokyo Heliport residents:

  • Tokyo Fire Department Aviation Unit, Koto Aviation Center
  • Tokyo Metropolitan Police Department Aviation Unit, Koto Flight Center
  • Aero Asahi Corporation

All possess facilities that would be the envy of the Japan Coast Guard personnel working in their by comparison somewhat dated abode across Tokyo Bay at Haneda Air Station, the subject of the previous report.

NOTE: Despite the lack of a checkpoint or any warning notices, security considerations prohibit even outside photography when on Tokyo Heliport premises. J-HangarSpace is thus unable to open this report with an uncluttered photo of the main building and control tower, taken on the day before the restriction was made clear just a few yards away from the public highway. For the same reason, the report of  the visit to the Tokyo Metropolitan Police Department Aviation Unit’s Koto Flight Center includes no photographs taken on TMPD premises. (It thus came as an unexpected privilege to later be allowed to photograph from the roof of the Aero Asahi facility, which is adjacent to that same heliport building.)

Tokyo Heliport

In a scenic location overlooking Tokyo Bay, the current Tokyo Heliport opened 45 years ago, on June 15, 1972, replacing a facility at nearby Tatsumi that had been operational since 1964. Having undergone gradual expansion from 1990 onward, a new management building and control tower was completed in May 2011. Currently utilized by around 100 companies, the thriving heliport provides employment for more than 800 people. The apron has no less than 38 helicopter pads, 10 of which can accommodate larger types.

  • Tokyo Fire Department Aviation Unit, Koto Aviation Center

The first port of call on the tour was the Tokyo Fire Department (TFD) Aviation Unit, the distinctive red aircraft of which are a familiar sight in the skies over and around Tokyo.

The TFD facility at Tokyo Heliport is officially referred to as the Koto Aviation Center, after the name of the Tokyo ward in which the heliport is located. Its sister facility, the Tama Aviation Center, commenced operations in September 1994 and is likewise co-located with a police unit at JGSDF Tachikawa Army Camp in west Tokyo. In recent years, the TFD Aviation Unit has benefited from funding that permitted the acquisition of two new helicopters in 2014 and, in October 2015, the renovation and reconstruction of its Koto Aviation Center building.

From its two bases the TFD Aviation Unit currently operates a total of eight aircraft, divided exactly between the medium (Dauphin) and large (Puma) classes of helicopter. The first of its kind in Japan, the unit commenced operations from Tatsumi with a Sud-Aviation Alouette III exactly 50 years ago, in April 1967. Since then, the TFD has remained brand loyal to the French manufacturer through its name changes, from Aérospatiale and Eurocopter to what is now Airbus Helicopters. Both classes of helicopter are a mix of one earlier version (AS365N2, AS332L1) alongside three examples of a later version (AS365N3; EC225LP, now known as the H225). The unit notched up 60,000 accident-free flying hours in October 2007; the 70,000-hour mark was passed in September 2012.

Tokyo Police AS365N3One of the three AS365N3s in service with the TFD Aviation Unit, Ootaka (Goshawk) has the turret
containing its L3-WESCAM 36x magnification camera and video transmission system
refitted after maintenance.

The TFD’s fiscal 2017 budget includes two items under an allocation of 601.1 million yen for the “upgrading and improvement of aerial firefighting systems”: a replacement for the AS332L1, to be recorded under the fiscal 2019 budget to ease Tokyo’s debt burden, and the supply of spare parts to upgrade the AS365N2.

In terms of total numbers of personnel, the unit comprises 26 pilots, 38 maintenance personnel and 21 administrative support staff members.

Present in the TFD hangar at the time of the visit were one example of each of the two newer classes of helicopter operated, an AS365N3 and an EC225LP.

Overview of Operations

From its two bases, the TFD undertakes the full gamut of the operations that would be expected of an airborne firefighting unit in Tokyo.

An obvious priority is placed on preparedness to respond to and deal with major residential fires, be they in the older parts of the city or in modern high-rise apartment buildings. The belly tanks on the unit’s EC225LPs hold 2,700 litres and can be refilled while hovering over a lake or river. When combating a building fire, 600 litres of water (or foam) a minute can be discharged via a swiveling, side-mounted boom that is around 7 metres long and has a range of 30–40 metres. An example of this type of system, the Simplex Model 516 High-Rise Firefighting System or SkyCannon, gained Japanese authority certification and was tested by the unit on an EC225LP in September 2015.

Tokyo Police EC225LPAlso present in the TFD Aviation Unit hangar was Hakuchō (Swan), one of the two EC225LP helicopters
that entered service in the spring of 2014 as part of a fleet upgrade. The black mounting on the side of 
the fuselage is for a Simplex SkyCannon firefighting boom.

Should any forest fires break out in the areas around Tokyo, all 2,700 litres of water can be dropped directly from the belly-mounted tank in one salvo; the same FireAttacker tank fitted to the smaller helicopters holds 900 litres. Information gathered and images taken at the scene of any incident can be relayed back to base in real time for prompt assessment.

As and when needed, the capital’s helicopters are ideally located to support local prefectural aviation units, the cities of Mito in Ibaraki Prefecture, Utsunomiya (Tochigi), Kofu (Yamanashi) and Mishima (Shizuoka) being just over 20 minutes’ flight time away. In September 2014, the Aviation Unit was deployed to Nagano Prefecture following a catastrophic volcanic eruption on Mt. Ontake, only to return two months later when the northern part of the prefecture suffered a major earthquake; these two disasters alone claimed a total of nearly 100 lives.

On March 11, 2011, the Aviation Unit was naturally immediately called upon following what became known as the Great East Japan Earthquake, which triggered tsunamis along Japan’s northeastern coastline. The three aircraft that were airborne at the time returned to base, two of them being rapidly relaunched to provide initial assessments of any damage suffered in the Tokyo area. Then deployed further afield, the unit remained heavily involved in coordinated operations in the disaster-affected areas of the Tohoku region until May 13, a total of 64 days.

Tokyo Fire AS365N3 (2)On its main cabin doors, JA01FD Ootaka also bears the name and initials of the organization to which it is officially registered, the Fire and Disaster Management Agency (FDMA) that reports to the Ministry of Internal Affairs and Communications. Also carrying the TFD logo (below) on its tail, the aircraft officially joined the Aviation Unit’s ranks at a ceremony held at the Tama Aviation Center
in Tachikawa on March 23, 2006.

Overwater domestic operations extend out to the Pacific Ocean islands administered by the Tokyo Metropolitan Government. These operations typically involve the airlifting of medical cases from Izu-Oshima, also just over 20 minutes by helicopter, or Aogashima, around 90 minutes away. Recent years have also seen the unit coming to inhabitants’ aid in response to a volcanic eruption on Miyake Island (2012) and landslides on Izu-Oshima (2013).

Even further afield, personnel and helicopters are sent overseas as part of Japan’s contribution to international responses to natural disasters. In the other direction, delegations from other Asian countries have visited Tokyo to witness first-hand and learn from the Aviation Unit’s operations and techniques.

Other than the practice of waterbombing techniques, regular training exercises involve hoist rescues, the lifting of underslung loads and familiarization with new equipment. The latter includes a special underslung rescue gondola, with capacity for up to 15 people, designed for use in rapid, high-capacity evacuation situations, such as tsunamis and high-rise building fires.

Tokyo Police EC225LP (2)The hoist fitted to the EC225LP has a 272kg load capacity, the same as the AS365N3. At 3.8 metric tons,
its underslung load-carrying capacity is more than double that of the smaller aircraft’s 1.6 metric tons.

Joint training exercises aim to fine tune close collaboration with other prefectures as well as with other services and agencies, such as Self-Defense Force (SDF) and Japan Coast Guard units.

Hyper Active

Established under the TFD Aviation Unit in a ceremony on the day of the traditional Tokyo Fire Department New Year parade on January 6, 2016, the 44-man Air Fire Rescue Task Forces—also referred to as Air Hyper Rescue—are divided into two elite teams, one specializing in rescue, the other emergency medical services (EMS). Both are primarily based at the Koto Aviation Center, with a detachment at the Tama Aviation Center.

One area of expertise for the new unit is the mounting of rescues from high-rise buildings, which are defined as having 11 floors or more, in other words above the height reachable by a TFD fire engine ladder. In June 2015, The Japan Times reported that the number of such properties in the capital stood at around 12,500 and was steadily growing, and that 2013 had seen 83 fires break out above the 11th floor, almost double the figure for 2003. In May 2016, there were 13 projects for residential properties of 50 floors or more. If you factor in the difficulties of road access and the likelihood of fire hydrant damage in an earthquake, maintaining an airborne option is essential.

On March 1, 2016, the multilateral approach was put to the test when three Aviation Unit helicopters and Air Hyper Rescue personnel participated in a large-scale training drill as part of a firefighting festival held in the Shinagawa area of downtown Tokyo. Designed to raise and maintain public awareness of fire prevention, around 150 TFD and SDF personnel took part in the drill. The setting assumed that a fire had broken out in the Sea Fort Square Center Building, a 23-storey office block that forms part of a complex of shops, offices and residences. Including some fine shots of Hakuchō “in action” with its SkyCannon firefighting boom, a selection of photos from the event can be found here [link].

The Aviation Unit has now added regular training to minimize the time taken to position the Air Hyper Rescue early response vehicle on a special platform for safe airlift to the site of any disaster.

Tokyo Police AS365N3 (3)AS365N3 JA119E Kamome (Seagull) came home to roost later in the afternoon. This aircraft has been
in service with the TFD Aviation Unit since March 2009. The odd man out medium-sized helicopter in
the fleet is a 1997-vintage AS365N2.

• Tokyo Metropolitan Police Department Aviation Unit, Koto Flight Center

Modern-day police work the world over benefits greatly from the helicopter’s mobility and rapid response capabilities. Operations in the Tokyo metropolitan area fall broadly into four categories: patrols, including traffic surveillance; searches, be they for accident survivors or crime suspects, including the use of forward-looking infrared radar (FLIR); rescue missions; and information gathering at the scene of any incidents.

From humble beginnings with a Bell 47G-2 named Harukaze (Spring Breeze) in October 1959, the Tokyo Metropolitan Police Department (TMPD) Aviation Unit currently operates 14 helicopters, not surprisingly making the unit by far and away the largest of its kind in the country. By way of comparison, in other parts of the country much depends on the size of the prefecture’s population and budget: most operate only one helicopter, likewise densely populated Osaka has seven, while Hokkaido has five aircraft to cover an expanse the size of Austria.

Reporting to the National Police Agency (NPA), the TMPD officially formed its Aviation Unit in April 1964 and has operated nearly 40 rotorcraft in its time. The only exception was the somewhat more sedate Airship Industries Skyship 600 airship, which was also bestowed with the name Harukaze and remained in service from March 1989 to March 1994. During this time, its slow-moving bulk lent itself well to the additional use as an airborne billboard, here [link] urging the populace’s cooperation in criminal investigations.

To simplify the coordination of operations, the TMPD unit’s current aircraft share the same two base locations as the Tokyo Fire Department Aviation Unit: Tokyo Heliport (known to the police as the Koto Flight Center), where 18 pilots are based, and the Tachikawa Flight Center with 10 pilots. Although based in Tokyo, the TMPD unit’s operations are by no means confined to the capital, as deployments are mounted anywhere in the country when required; its back catalogue of participation in major disaster relief operations closely follows that of the TFD.

Tokyo Police AB139 TachikawaOne of three aircraft present in the pristine TMPD hangar at the time of the visit, AB139 Ootori 4
joined the unit’s ranks in February 2006. Seen here at Tachikawa in November 2013, the aircraft
has since been equipped with a locally customized, side-mounted CineflexT14 camera.

Major operations unique to the capital include the monitoring of the Tokyo Marathon. The holding of the 2020 Tokyo Olympics and Paralympics at venues in and around the city will involve the drafting in of aircraft from surrounding prefectures as reinforcements. A case of TMPD aircraft moving in the other direction was the G7 Ise-Shima Summit in May 2016, which involved a massive police presence, in terms of helicopters as well as personnel, as had the G8 Hokkaido-Toyako Summit in July 2008.

A short video of fast cuts of TMPD Aviation Unit operations can be found on the TMPD website [link].

Whereas its Tokyo Fire Department sister service has remained loyal to what is now Airbus Helicopters Japan, the TMPD rang the bell on its initial provider and since the late 1990s has sourced its aircraft primarily from Europe. The only exception was the 2011 addition of a passenger transport-configured Sikorsky S-92 (see this 2016 YouTube [link]), which was undergoing maintenance at the time of the visit.

Tokyo Police A109Noticed making its way around to its parking spot was the TMPD’s sole Agusta (now Leonardo-
Finmeccanica) A109E Power,
Hayabusa 5. Following the order announced in June 2016, the
aircraft is to be joined next year by two of the updated AW109 Trekker version, which will be
the first of the type to be used for law enforcement purposes in Asia

Generally, TMPD pilots tend to be police officers who have passed suitability testing conducted by the Japan Ministry of Defense before acquiring business pilot qualifications at accredited organizations. Also drawn from police ranks, maintenance personnel holding at least a Class 2 aviation mechanic’s license are recruited following a selection process.

Traditionally taking disaster response and rescue operations in general as its theme, the airshow held at Tachikawa in autumn every year provides the Tokyo police and fire department air units with a golden opportunity to demonstrate their capabilities to the taxpaying public.

That first Bell helicopter remains on display at the Tokyo Metropolitan Police Museum, which is due to reopen after a year-long refurbishment this spring (2017).

The video can be found here [link]; the H155 footage starts at around the four-minute mark.

• Aero Asahi Corporation

The last but not least stop on the tour was Aero Asahi Corporation (AAC), which bases not only its rotorcraft aviation business but also its corporate headquarters at Tokyo Heliport.

Founded in July 1955, the original company split its activities into fixed- and rotary-wing operations and accordingly changed their tradenames to Asahi Airlines Co. and Asahi Helicopter Co., Ltd., respectively, in September the following year.

The name Aero Asahi (Asahi Kōyō in Japanese) dates from the July 1, 1982, merger of Asahi Helicopter and the helicopter operations of Toyo Aviation (Tōyō Kōkū Jigyō, literally Oriental Air Enterprises), which had itself been founded in 1960. The two companies had been engaged in a business partnership since as early as July 1961.

Today part of the Toyota Motor Corporation group of companies, AAC is involved in all aspects of helicopter operations. The main focus of J-HangarSpace interest is the company’s major involvement in the nationwide Doctor-Heli EMS services. Another Doctor-Heli operator, Nagoya airport-based Central Helicopter Service, Ltd. (formerly Kawasaki Helicopter System Ltd.), which has been an Aero Asahi group company since March 2007, will be celebrating its 50th anniversary on March 10 this year.

In its own right, AAC operates a fleet of 15 helicopters configured for Doctor-Heli operations, eight BK117C-2s and seven MD902 Explorers. These currently provide EMS cover for 12 hospitals in 10 prefectures, from Asahikawa in Hokkaido to Kumamoto in Kyushu. (The data included on the Doctor-Heli Network page of this website will be expanded in due course.)

Aero Asahi MD902 (1)At the time of the visit, two MD902s were receiving attention. The maintenance bays in the AAC
hangar do not lend themselves well to photography from the designated walkways.

Kawasaki Air Rescue AS365N3Seen from the roof of the Aero Asahi facility, AS365N3+ Sokokaze (Zephyr) 2, the 2015 addition to the
Kawasaki Air Rescue operation, is parked on its assigned spot on the apron. Although the city of
Kawasaki lies in neighbouring Kanagawa Prefecture, its firefighting aviation unit has been
a permanent Tokyo Heliport resident since the start of its operations in July 1985.

NHK TV AW139The Agusta Westland AW139 operated for Japan Broadcasting Corporation (NHK) by All Nippon
Helicopters (ANH) since 2014 is towed out into the afternoon sun at Tokyo Heliport. Although
not currently part of J-HangarSpace coverage, a feature on the operations of the broadcast
news helicopters could well be added at some point. That’s the Tokyo Heliport-based
Kawasaki Air Rescue AS365N3+ again in the background.

Once again, J-HangarSpace is greatly indebted to Keiichi Akaboshi of the Japan Aircraft Pilot Association and Ken Yanai of the Japan Business Aviation Association for their not insignificant part in organizing what was a most enjoyable visit.

Getting There

The nearest train station to Tokyo Heliport is Shin-Kiba, on the JR Keiyo and Musashino lines, the TWR Rinkai Line (that connects directly with the JR Saikyo Line) and the Yurakucho Line on the Tokyo Metro network. From there, a 10-minute loop-line bus ride brings you to a stop in front of the main entrance, which only offers a view of a row of heliport buildings (plus see security note above). The favoured spots are from footpaths on the far side of the apron, as seen on this map from 2006 [link], and from Shin-Kiba Rokudo Park.

The Lie of the Land

Shot in July 2016, this YouTube video [link] gives a good idea of what can be seen from above the fence line, should you happen to have a ladder handy.

As the video shows, the heliport is prone to strong winds—as evidenced, too, by the presence of a wind turbine in the area—and in summer the long grass can present an obstacle to more than just the birds for which it is intended to act as a deterrent.

To end with, a general view of the heliport complex can be gained from this October 2014 video [link], showing the arrival and departure of a Tokyo Fire Department EC225.

Location Report 8

Japan Coast Guard Haneda Air Station, Tokyo
November 11, 2016

Japan Coast Guard HanedaThe view out through the doors of the JCG Haneda Air Station hangar. Note that the nearest helicopter,
EC225LP Super Puma JA691A
Inuwashi (Golden Eagle), lacks its main rotor.

The Japan Coast Guard (JCG) personnel at Haneda Air Station control all the air operations of the service’s 3rd Region, which is headquartered and homeported at Yokohama in neighbouring Kanagawa Prefecture. One of the 11 such regions into which Japan is divided for the purposes of monitoring and safeguarding its territorial waters, the 3rd’s normal land-based complement resident at Haneda currently comprises four specially equipped fixed-wing aircraft—two of the service’s nine Bombardier Dash 8-Q300s and both of its Gulfstream Aerospace GV Sea Watch aircraft—and two Airbus Helicopters Super Pumas, one of the earlier AS332L-1s and an EC225LP. Another two AS332L-1s are embarked on the Shikishima (PLH31) patrol vessel, with another pair of EC225LPs aboard the Akitsushima (PLH32). All four helicopters are naturally shore-based at Haneda when their parent vessels are in port.

A former Haneda resident, the service’s first AS332L-1 happened to be undergoing maintenance at Sendai airport in Miyagi Prefecture when the tsunami struck on March 11, 2011. Decommissioned three months later, the already 19-year-old aircraft was eventually refurbished in Canada and is currently being flown by a civil operator in Norway. The Bell 412EP previously based at Haneda was transferred to the 6th Region’s Hiroshima Air Station early in 2015.

At the time of J-HangarSpace’s visit, both of the GVs were absent and only one of the Dash 8s was present but undergoing maintenance and therefore off limits. Coincidentally, this aircraft also sustained damage after being caught in the March 2011 tsunami, but was eventually returned to service in March 2012.

JCG Dash 8 HanedaTucked away in a corner with its cabin brimming with test equipment while undergoing maintenance
was Bombardier Dash 8-Q300 JA722A
Mizunagi (Shearwater). Delivered early in 2009, the aircraft
remained out of service for just over a year after sustaining damage in the March 2011
tsunami at Sendai, Miyagi Prefecture.

Origins

The JCG can trace its origins back to May 1, 1948, during the Allied Occupation that followed the end of World War II, when the Maritime Safety Agency (MSA) was formed as a then extra-ministerial agency under the control of the transport minister to counter illegal activities, such as smuggling and acts tantamount to piracy, which were rife in postwar Japan. The regional organization officially came into being on January 1, 1962. Although retaining its Japanese name (Kaijōhoanchō), the MSA officially became the Japan Coast Guard on April 1, 2000, and reports to the Minister of Land, Infrastructure and Transport; the service’s senior officer bears the rank of commandant.

A fledgling aviation element was added to the service in 1953, when its first aircraft, a Kawasaki-Bell 47D-1 and a Sikorsky S-55, were commissioned at Tateyama, Chiba Prefecture, on July 12 and December 12, respectively. The first fixed-wing aircraft was a Beech E18S that arrived in March 1956. In July 1958, operations were relocated to Haneda Airport, where the current facilities were opened in August 1967.

JCG Haneda emblem

The general administrative base operations support section and operational liaison and coordination sections are housed in seemingly cramped conditions on the floor above the hangar. It is here, too, that intelligence gathered from the aircraft is assessed. Japan is by no means alone in facing the problem of aging infrastructure. As the increased burden of responsibilities that have been placed on the JCG mean operations at Haneda have outgrown the space available, presumably there are contingency plans being made to replace or somehow upgrade and expand the facilities, when funding permits.

Extensive Area of Responsibility

A map on the 3rd Region’s website [link] helps to gain a better idea of the distances involved in operations that can and do extend to the nation’s easternmost and southernmost points. From a point running roughly due south from the coast as far west as the border between Shizuoka and Aichi prefectures, the demarcation line includes the 200 nautical mile (370km) exclusive economic zone (EEZ) around uninhabited (and disputed) Okinotori Island, which lies in the tropics just over 1,000nm (1,850km) to the south and although barely visible at high tide is deemed to be part of Tokyo. From the border between Ibaraki and Fukushima prefectures, another demarcation line extends out into the Pacific Ocean and accommodates the separate EEZ around Minamitori (Marcus) Island, some 1,150nm (2,130km) distant. Under a treaty signed with the United States in December 1986, the area of Japan’s high seas search and rescue (SAR) responsibilities extends across to 165 degrees east and down to 17 degrees north, up to 1,200nm (2,200km) from the Japanese mainland.

A tragic episode in March 2014 that highlighted the distances sometimes involved and the coordination needed in the operations the JCG undertakes was the dispatch of both GV Sea Watch aircraft and two patrol vessels as well as a JMSDF US-2 amphibian carrying an SRT unit to that far-flung Okinotori Island.

A floating pier had capsized during the building of port facilities at the atoll, throwing 16 construction workers into the sea. The JCG crews and SRT divers were charged with searching for two men listed as missing, but ultimately the tragic incident claimed seven lives and the mission changed to transporting the bodies of five victims that were found, first to Iwo To by JCG helicopter and from there by GV to Haneda, and airlifting those injured to hospital.

A Raft of Varied Operations

As you would expect, the JCG’s remit includes the round-the-clock maintaining of all aspects of maritime safety, the upholding of laws, the conducting of fishery and environmental protection operations as well as preparing for and coordinating responses to natural and man-made disasters.

Nowadays, all of the JCG’s regions are also tasked with a variety of potentially hazardous operations that far exceed assisting those in peril on or near the sea, the ‘bread and butter’ of coast guard services the world over. These additional operations form part of a comparatively new mission for many of the world’s coast guards, namely their use as a means of force projection, as their vessels are generally perceived as being less intimidating to other governments than those operated by so-called blue water navies. In Japan’s case, the focus of such operations has switched from the Sea of Japan, where incursions by “suspicious” (North Korean) vessels had to be thwarted in the late 90s and early 2000s, to the overlapping EEZs in the South China Sea, off Okinawa. For any members of the visiting group who ventured onto the EC225LP that was made available for viewing, a crew member was wisely on hand to politely request them not to photograph the helicopter communications suite located immediately behind the flight deck.

JCG AS332L-1Used for a talk that featured a hoist demonstration, AS332L-1 JA6806 Wakawashi (Young Eagle)
 was one of two delivered in May 1997 and assigned for use by the Special Rescue Team.

A short lecture given by a JCG member highlighted some of the other, more peaceful main operations conducted over the Pacific Ocean from Haneda. These include the ferrying of inhabitants in urgent need of medical care from remote islands to hospital, in which case helicopter range is extended by leapfrogging from ship to ship to refuel. The Dash 8 crews are utilizing the aircraft’s airborne laser hydrography (ALH) equipment to map the ocean floor and have also been engaged in the GPS mapping of tiny Nishinoshima, one of the Ogasawara island chain, the area of which was increased by volcanic activity over a two-year period from late in 2013.

In early 2016, a GV aircraft and an EC225LP operating from the Akitsushima transported the Imperial couple on their official visit to Palau. Operations on land included taking part in the concerted operations to provide disaster relief in Iwate Prefecture following the typhoon that struck in September.

The international nature of certain aspects of the JCG’s operations has resulted in Haneda-based aircraft taking part in combined anti-piracy training exercises and joining in the search for clues to solve the mystery of Malaysian Airlines flight MH370, which disappeared in March 2014.

The JCG was one of the 20% of operators unaffected by a grounding order imposed by the European Aviation Safety Agency (EASA) on commercial operations by Airbus Helicopters H225 (that is EC225LP and AS332L-2) Super Puma helicopters between June and October 2016 following a fatal accident involving an H225 in Norway in April.

Haneda: 30-Year Home to Special Rescue Team

JCG SRT book coverCoincidentally, a book about the Special Rescue Team, with content overseen by the 3rd Region,
was released by the Japanese government publisher in November 2016
.

Sharing the base at Haneda are the six rescue diver units, each of six men, and the five operational support staff that make up the JCG’s Special Rescue Team (SRT), which maintains the capabilities necessary to respond to major maritime accidents and disasters, not only inside the 3rd Region’s area but also nationwide. To aid its rapid response, two AS332L-1s and one of the GV Sea Watch aircraft are currently placed at its disposal.

The event that prompted the formation of the first five-man SRT in October 1975 was the explosion and fire that occurred following a collision between a Japanese-registered tanker carrying liquefied petroleum gas, the Yuyo Maru No. 10, and the Liberian freighter Pacific Alice in Tokyo Bay on November 9, 1974, claiming the lives of 33 seamen. Initially trained by the Tokyo Metropolitan Fire Department and assigned to the 3rd Region’s HQ, it was an expanded SRT that was relocated to the Haneda Air Station 30 years ago, in April 1986.

The unit was popularized first by a manga series named Umizaru (Sea Monkeys), which was based on the accounts of actual rescues and published between 1998 and 2001. The stories were adapted for a TV drama series and followed by four fictional full-length feature films of the same name, the last of which was released in 2012.

The SRT was heavily involved in operations in the aftermath of the Great East Japan Earthquake in 2011, the year in which the team surpassed the 4,000 mark for the number of missions undertaken.

All the tour group members were allowed to experience donning the strap and being winched off the ground, albeit by the hoist of a motionless helicopter parked safely and stably inside the hangar.

Location Report 7

Japan Ministry of Defense, Ichigaya, Tokyo
May 14, 2014

Ichigaya map coverThe photo on the cover of the guide map shows the 220m-high communications tower and Building A. Tokyo’s largest public office building, the latter boasts two rooftop helipads and has four of its
23 storeys below ground.

In the year in which Japan’s three Self-Defense Forces mark their 60th anniversary, it seemed only fitting for J-HangarSpace to join a tour of their Tokyo nerve centre. Located on the city’s highest point, which is all of 103 feet (31.4 metres) above sea level, the area that is now home to the Ministry of Defense has witnessed some epoch-making events.

Situated to the west of Ichigaya Station, the plateau is popularly known as Ichigayadai. It was due to the modest vantage point offered that the site was granted to a Tokugawa family clan in 1656 for them to build a residence and defences close to Edo (Tokyo) Castle. The land was returned to the nation with the restoration of imperial rule under the Emperor Meiji in 1868 and, from 1874 until 1937, was used for the Imperial Japanese Army Academy, initially housing training elements formerly based in Kyoto.

In the interim period, a major upheaval (literally) was caused by the Great Kanto Earthquake of 1923 that took the lives of thousands, left large areas of Tokyo devastated, and the buildings at Ichigaya badly damaged.

In 1937, the imposing Building No. 1 was completed and progressively housed the Imperial Headquarters, the Ministry of War, and the General Staff Office. An obvious target for requisitioning during the postwar Allied Occupation, the surprisingly unscathed building was used for the International Military Tribunal for the Far East. The U.S. Army Forces Far East Command was in residence before the building’s return to Japanese ownership in 1959. The first postwar Japanese utilization was as the JGSDF’s Eastern Army Headquarters from 1960.

Building No. 1 modelDisplayed in Ichigaya Memorial Hall, this 1/50th scale model gives a good idea of what Building No.1 looked like in its heyday, when on the spot now occupied by Building A. The Memorial Hall is the front section to the right, relocated and renovated but with the balcony structure removed.

The first tour of what was then the Japan Defense Agency was conducted in June 2000, a mere month after it had moved from its former location, Hinokicho in Tokyo’s Roppongi district. The agency was granted ministry status and officially changed its name on January 9, 2007, and the number of tour participants surpassed the 300,000 mark in August 2012.

Covering just under 60 acres (23 hectares), the site today is the workplace of and, in some cases, home to around 10,000 personnel. At the start of the working day, a constant stream of people can be seen either walking up the imposing flights of steps or taking the escalators from street level.

This report follows the sequence of the morning tour after the donning of security passes at the main gate on Yasukuni-dori. The tour lasts 2 hours 15 minutes. The slightly shorter afternoon tour includes a visit to a public information exhibit room in the Welfare Building instead of the Outside Helicopter Display and Memorial Zone.

The first stop is the Honour Guard Ceremony Square, where a guide gives an explanation of the roles of three of the green-roofed buildings that make up the ministry: Buildings A (staff office core functions); B (communications); and C (intelligence gathering and analysis).

Memorial Hall frontThe front façade of the Ichigaya Memorial Hall, the relocated and renovated former front section of Building No. 1 that dates back to the mid-1930s.

Tour groups then proceed to the tour high point, Ichigaya Memorial Hall, which as part of Building No. 1 was first completed in 1937 to house the Imperial Japanese Military Academy. Now located at the far corner, to the left of the communications tower, this representative section of Building No. 1 was moved from its original location to make way for Building A, rebuilt, and restored.

Having first exchanged shoes for slippers, tour members are escorted through the main entrance hall of what is in essence a rebuilt time capsule.

The next stop is the dimly lit Grand Hall, where tour groups are shown an informative video entitled The History of Ichigayadai (in Japanese with English subtitles). This very hall served as the court room for the International Military Tribunal for the Far East, otherwise known as the Tokyo Trials, which ran from May 1946 to November 1948. The guides point out the well-disguised patches in the wooden flooring where the original tiles had to be replaced.

Tokyo Trials courtThe view looking down from what was the public gallery during the Tokyo Trials. The left-hand side of the Grand Hall is permanently set up for the tour film show, the right-hand side consists of displays of uniforms and other memorabilia.

Tour groups are shown other rooms upstairs, including the office formerly used in turn by the principal of the Imperial Japanese Military Academy, the Minister of War, and the commanding officer of the JGSDF’s Eastern Army.

Although painstakingly rebuilt, the building lacks its former balcony. It was from here that the author and film actor Yukio Mishima, having arranged to meet the Eastern Army’s commanding officer, delivered an impassioned speech during a coup attempt in November 1970. Met with derision by based troops, Mishima went back inside, where followers participated in his ritual suicide. Three sword cuts in a wooden door attest to the episode.

1934 military exercise Gunma

Due to the difficulties caused by reflections, this shows only a small section of a large glass photo image taken at a military exercise in Gunma Prefecture in 1934. Among the 3,800 people pictured in the full-size photo, who include the Showa emperor (1901–1989), guides point out two men who went on to become well-known figures: the then Vice-Admiral Isoroku Yamamoto (1884–1943) and the then
newly appointed commander of the 24th Infantry Brigade (and former chief of the
Defense Ministry Personnel Department) Maj. Gen. Hideki Tojo (1884–1948).

After walking past on-site personnel accommodation and taking a break at the Welfare Building, which includes a Starbucks, a convenience store and stores selling SDF souvenirs, the morning tour proceeds to the Outside Helicopter Display. Although overlooked by office buildings, photography is prohibited when passing a sports field en route. Next to JGSDF personnel engaged in physical fitness exercises, revetments bear witness to the occasional presence of mobile Patriot anti-ballistic missile launchers as a precaution against errant North Korean test firings.

Ichigaya UH-1HDelivered to the JGSDF in 1977, the displayed UH-1H was withdrawn from active service with the Western Region Helicopter Squadron from Metabaru Army Camp, Saga Prefecture, on February 19, 2002. The aircraft has been a (as you would expect) well-kept permanent fixture at the Ministry of Defense since April 1, 2003.

Dating back to 1962 and renovated in 1980, the main monument in the Memorial Zone is dedicated to the more than 1,800 SDF personnel who have lost their lives on active duty. As its name suggests, the area was made into a central repository for a dozen or so military monuments and memorials that were previously scattered around other locations. These are mostly positioned discreetly behind the main monument, away from the gaze of passing tour groups.

Ichigaya Memorial ZoneThe main monument in the Memorial Zone is carved in black and white granite in the shape of Mt. Fuji.

The occupants of the three other main buildings in the complex, which include the Technical Research and Development Institute (TRDI) in Building D, are mentioned on the way to the top of the escalator that leads back down to the main gate.

Location Report 6

2014 Spring Festival,
U.S. Naval Air Facility Atsugi, Kanagawa Prefecture
May 3, 2014

For many years, the JMSDF traditionally held a combined Maytime children’s event and air show on their side of Atsugi base to coincide with the local Yamato City festival. In more recent times, however, the service has saved money and effort by merely towing some aircraft across to join the static park on the day of their U.S. Navy neighbour’s open house, also held in May. Although not billed as an air show as such, this does feature U.S. military aircraft taking off on afternoon training flights.

The main gate is the sole entry point on Spring Festival Saturday, or Sunday if bad weather has caused a day’s postponement. Prior to the official opening at 10 a.m., the queue to gain entry this year extended along from the main gate, then left all the way down a long road, then left again before turning back on itself in a park! With temperatures in the mid-20s, a survival kit of drinking water, sunglasses, and a hat is highly recommended, if not essential. (See How to Get There section below)

Despite the huge crowd expected, the prime reason of J-HangarSpace’s visit was the opportunity to take some close-ups of a based Kawasaki P-1 patrol aircraft. The effort was rewarded not only by the presence of a P-1 in the static display, but also by another being surprisingly put through its paces on a demonstration flight. While the two prototypes remain engaged on manufacturer testing, all five of the current fleet of five production aircraft are assigned to the JMSDF 51st Fleet Air Squadron’s 511th Flight and could be seen around Atsugi.

With company test pilots Akihiro Sekido and Yoshinao Baba at the controls, the first prototype XP-1 made its maiden flight on September 28, 2007, and the two prototypes were handed over at Atsugi on March 12, 2013. The first prototype is now engaged on a variety of test programmes as the UP-1 at Gifu, and the second prototype has been upgraded to production aircraft standard. The most recent aircraft to join the test programme, the fifth production aircraft (5507) made its maiden flight on December 20, 2013.

This Location Report focuses on providing a photo commentary of the aircraft’s display. A Nose to Tail photo feature has been added to the JMSDF Aircraft Programmes page.

The lightly loaded aircraft gathers speed at the start of its takeoff run (above) and gets airborne within a very short distance (below). Its four IHI F7-10 turbofan engines encased in noise-reduction panels,
the P-1 is remarkably quiet for a military aircraft. More importantly, the panels’ primary role is in
inhibiting electronic interference to the aircraft’s sensors.

P-1 Atsugi takeoff

P-1 Atsugi low passIn its element on a high-speed flypast, the P-1’s airliner lines belie its role as an anti-submarine warfare (ASW) aircraft. The prototypes have already been used for test flights with underwing-mounted
AGM-65F Maverick and ATM-84A-1C Harpoon missiles as well as for decoy flare dispenser tests.
The P-1’s wing has been designed to accommodate eight underwing hardpoints, and depth
charges or unguided torpedoes can be dropped from the aircraft’s ventral weapons bay.

aircraft equipped with a fly-by-light control system that, on an aircraft bristling
with sensors, offers the advantage of reduced electromagnetic interference.

 How To Get There

The closest station to the Atsugi NAF main gate is Sagamino on the Sotetsu Line. On show day, all you need do is follow the crowds on a 15-minute walk.

Sagamino is only two stops from Ebina on the Odakyu Line, around 50 minutes by express from Shinjuku Station in Tokyo. Be aware that Odakyu Line trains stop at the similar-sounding Sagamiono Station.

For the May 2015 event, non-Japanese nationals should look out for Gate 1, tucked away to the right of the main entrance; this fast-track entry point for the disabled is open to them, too. Don’t forget to take your passport or Japan resident card for the security procedures.

Sakura Matsuri
(Cherry Blossom Festival),
JASDF Kumagaya Air Base, Saitama Prefecture
April 6, 2014

kumagaya posterTaken from the Kumagaya AB website, the poster advertising this year’s Sakura Matsuri gives a good idea of the crowds the event normally attracts.

Kumagaya AB

The event now known as the Sakura Matsuri (Cherry Blossom Festival) at Kumagaya AB has been a permanent fixture in the local spring calendar since the 1960s. Boasting around 900 cherry trees, the base provides the Japanese with an ideal location to pursue their favourite if fleeting pastime of eating and drinking in groups beneath the pink blossom.

Lacking a runway and any based operational aircraft, the static display is limited to a visiting JASDF helicopter or two. For the most part, the afternoon flying display consists of a helicopter demonstration flight and appearances by aircraft from nearby Iruma AB. This year, flying displays by a Hyakuri-based UH-60J and a Fuji T-7 from Shizuhama had to be cancelled due to the weather, but a pair of Kawasaki T-4s from Iruma made three passes. Making for conditions that were suitable only for the most die-hard of visiting picnickers, strong winds served to keep attendance down to around 18,000 visitors for the day.

Another opportunity to visit the base is provided by the traditional O-Bon festival at the end of August.

Kumagaya Base Archives

Taking the first turn to the right on the way down from the main gate brings you to the Kyoiku Sankokan (literally Education Reference Centre). From the entrance lobby, a corridor naturally leads you first into a room covering Kumagaya’s early days.

From the mid-1930s until early 1945, the airfield was a hive of activity as an Imperial Japanese Army Air Force (IJAAF) flying school. Officially opened at a ceremony held December 14, 1935, the first intake of students commenced classes in the spring of 1936.

Ki-10IJAAF Kawasaki Type 95 (Ki-10) fighters were painted to represent Chinese Nationalist Air Force Polikarpov I-15 fighters for the filming of Moyuru Oozora (Burning Sky), which was filmed at
Kumagaya and released in 1940.

Kumagaya progressively took over the elementary pilot training functions formerly undertaken at Tokorozawa, also in Saitama, when space considerations at the latter dictated that the focus be placed on technical and maintenance training. By the late 1930s, Kumagaya was reportedly home to 200 instructors and a total of around 600 students. With the expansion of pilot training to meet combat demand, more than 20 satellite schools at one stage or another came under Kumagaya’s command. All training operations ceased at Kumagaya in February 1945, when the base was assigned to the 1st Air Army’s 52nd Air Division.

Naturally, the rooms are divided into two periods that reflect the airfield’s prewar and wartime IJAAF existence and the period from the mid-1950s to the present day.

Kugahara propellers(From top): Wooden propellers from an IJNAF Tachikawa Type 95-1 (Spruce) biplane trainer and an Otsu 4 Kata (Nieuport 29C) fighter; metal propellers from a North American T-6G Texan and
Beech T-34A Mentor.

Displayed in the corner of the first room to the left of the entrance is a stack of four propellers (see photo above). Next to those is a showcase containing relics—including a generator and parts of a fuel tank, oil cooler, piston, and wing—from a crashed Kawasaki Type 5 (Ki-100) fighter. A frame of photos placed in the same showcase was not well placed for reading, but a large framed display directly above reveals more of the details.

The main photo here shows 18th Flying Regiment pilot Master Sgt. Yasuo Heima, whose period of military training had started when he was accepted to be member of the Tokyo Army Air Cadet School’s ninth intake in October 1939 and ended upon his graduation from Kumagaya. Having seen action on the island of Timor in Southeast Asia in 1943, Heima was brought back to help defend Japan and was among those who took off from the 18th’s base at Matsudo in Chiba Prefecture to attack a formation of B-29s on April 7, 1945. Newspaper cuttings (dated February 24, 1972) report the discovery (after 27 years) of the aircraft Heima had been flying that day at a site near Koshigaya in Saitama; his had been the first combat loss of a Type 5.

Yasuo HeimaThe display in memory of Master Sgt. Yasuo Heima, killed in action on April 7, 1945. The newspaper cuttings detail the discovery of the Type 5 fighter he was flying that day. The lower left
handwritten text gives details of the Type 5, while the text on the right describes
the war situation at that time and Heima’s flying career.

Moving to the left from the poignant memorial to Master Sgt. Heima, the visitor is presented with further photographs. Two supplied by the wartime fighter pilot Susumu Koyama give some idea of what Kumagaya was like in its training school heyday.

Born on Okayama Prefecture in 1923, Koyama had entered the Tokyo Army Air Cadet School in April 1940 before starting a course at Kumagaya in April 1941.

First published in 1996 and reprinted in 2010, Koyama’s memoirs unfortunately only mention Kumagaya in passing in the first paragraph, in which he refers to leaving the school, encouraged by the pilot’s wings on his chest, on December 1, 1942, when Japan was in the thick of the Pacific War. He paints a picture of the newly qualified pilots walking in two and threes the kilometer or so to the train station to head off on their separate ways to their assigned units.

(Koyama’s first assignment was on the Nakajima Type 97 [Nate] with the 246th Flying Regiment based at Kakogawa near Osaka, but he was transferred to the Kawasaki Type 3 [Tony]-equipped 68th Fighter Unit in New Guinea in September 1943. Having managed to survive the war, Koyama eventually worked as a civilian pilot.)

Kumagaya Flying School 1
(Above and below) These photos give some idea of Kumagaya’s former existence as an IJAAF flight training school. They were donated by former student and wartime fighter pilot Susumu Koyama, then a resident of Matsuyama in Ehime Prefecture. In September 1943, Koyama was assigned to the Kawasaki Ki-61 (Tony)-equipped 68th Flying Regiment from Wewak airfield in New Guinea and later wrote a book about his experiences.

Kumagaya Flying School 2

Other Snapshots of Kumagaya Life in 1940s

Although not part of the archives, somewhat more of a student pilot’s perspective of life at Kumagaya can be gleaned from the memoirs of another IJAAF fighter pilot, Izumi Miura.

Born in what is now Kikugawa, Shizuoka Prefecture, in 1925, Miura entered the Tokyo Army Air Cadet School at age 15 in March 1940 and graduated from Kumagaya in November 1942, in both cases a month before Koyama.

The second chapter of Miura’s memoirs is devoted to his time at Kumagaya. At that time, the base was also the cradle of IJAAF bomber units, and he recalls the excitement of seeing formations of Mitsubishi Type 97 (Sally) bombers overhead as he stepped off the train at Kagohara station and the takeoffs and landings of the based Tachikawa Type 95 (Spruce) training aircraft.

Kumagaya Ki-9The unit marking of a red design on a white disc sported on the rudder of this Tachikawa Ki-9 (Spruce) trainer identifies the aircraft as one of the many examples of the type that were assigned to the Kumagaya Army Flying School. (Photo: via Wikimedia Commons)

Miura was one of 120 students who made up the 1st Company of Kumagaya’s tenth-term intake. For the first year, students were given tuition on the technical aspects required by tyro pilots, including aircraft engineering and—as it turns out, providing a link with the base’s current activities—meteorology and communications.

The book provides invaluable snapshots of student life at that time. Divided into groups of 12, the students would change into overalls every day for the practical part of the aircraft engineering course, which over five months involved stripping down and re-assembling an assigned Type 95; for the third repeat of the exercise, the time was reduced to 15 days. Miura relates the added pleasure the pilots derived from flying aircraft that they had helped to put together.

(Izumi Miura’s active career followed that of Susumu Koyama in that his first assignment was also to a Nate unit, the 4th Flying Regiment at Ozuki, Yamaguchi Prefecture, after which he transitioned to the Tony-equipped 78th in Harbin, China (at that time Japanese-held Manchukuo). After retiring from a long postwar career in the police force, Izumi Miura worked for a private company. He passed away aged 64 in October 1989.)

Kumagaya Flying School COsSeen in this displayed photo are five former Kumagaya Army base commanders: (Clockwise from top left): The third commander, Lt. Gen. Eijiro Ebashi; the second, Major Gen. Kenjiro Nagasawa;
the first, Major Gen. Tetsuji Giga; the fifth, Major Gen. Yoshio Hongo; and the
seventh commander, Major Gen. Katsuji Hirata.

Back at the archives, the next photo frame (shown above) contains portraits of five former Kumagaya base commanders. Seemingly unrelated to the surrounding photos, the handwritten note in the middle of a frame states that Japan’s first involvement in air combat took place [during World War I] at 6:00 a.m. on October 13, 1914, at the time of the fall of [German-held] Tsingtao [in China]. At that time a lieutenant, Nagasawa (written using different kanji to that under the photo of the second base commander), who was flying a Nieuport, came upon and attacked a Rumpler aircraft flown by German Navy Lt. [Gunther] Plüschow. (J-HangarSpace has sought clarification.)

The display case beneath these photos contains a wide range of course textbooks. These include aircraft handling manuals and books containing diagrams to accompany engineering courses on, for example, aircraft, instrumentation, and the Bristol Jupiter VI radial engine that Nakajima built under licence from 1925 as the Ha-1 Kotobuki (Longevity).

Mounted on the wall around the corner are a series of large paintings depicting IJAAF aircraft. Confining coverage to aviation-related content, subsequent displays contain models of early base buildings alongside examples of pilot clothing and equipment. The display case on the far wall contains radios and other communications equipment. Of pre-Kumagaya interest here are some photos taken at the time of the 1919 French Aviation Mission to Japan.

80th ShinbutaiA photo shows the 12 pilots assigned to the 80th Shinbutai—the name contains the meaning of “unit that will demonstrate the power wielded by the armed”—a special attack force formed from the Kumagaya-based 52nd Air Division in 1945. The photo is accompanied by a list giving the pilots’ names and
ranks as well as by inscriptions written by the pilots themselves. Eleven of those in the picture
were killed in action when flying solo in Tachikawa Ki-55 (
Ida) trainers against U.S. Navy
ships off Okinawa on April 22, 1945; the other pilot met the same fate on April 27.

More Poignant Reminders

Kumagaya very quickly became U.S. Army Camp Whittington in September 1945, the month after the end of the war, and remained so until handed back to Japanese ownership in July 1958. Officially given JASDF air base status in August 1958, Kumagaya welcomed the 2nd Air Training Squadron that had provisionally formed at Utsunomiya Army Camp in Tochigi Prefecture in March that year. The next major development came in October 1959, when a branch school of the 2nd Technical School (TS) was formed complete with a Non-Commissioned Officer Cadet School (NCOCS). In July 1961, the 2nd TS branch was given full status as the 4th TS, which was placed in command of the NCOCS. The names of graduates from the 53 intakes into the cadet school and a chronology covering the years from 1954 to 2011 are combined with plaques, uniforms, and insights into student life in a separate room.

Today, the area covered by the base (42 acres, 170,000 sq. metres) is about a fifth of what it was in its flying school heyday. The training courses run by the 4th TS focus on the operation and maintenance of IT-based equipment used in communications and weather prediction.

Equipped with a video screen at either end, the long room on the other side of the corridor from the entrance lobby is mainly geared toward PR and recruitment. Its displays therefore feature general exhibits on the JASDF. Flight instruments from a KV-107II are on display in one show case.

There was one small, quiet room in the Education Reference Centre where it seemed inappropriate to take photographs. With a memorial at one end directly opposite the door, the pure white walls on both sides bore photos of Kumagaya 4th Technical School graduates who had tragically lost their lives in SDF service. Giving their full names in Japanese and English, the four lost as a result of flying accidents were:

The following photos are arranged in the order the aircraft appear among the cherry trees on the left of the road leading down from the main gate. As you would expect, it can get quite crowded around these aircraft earlier in the day, so the best time to photograph them is when the show is coming to an end around 3 p.m. (This is generally the case with all static displays at air shows in Japan.) At Kumagaya the disadvantage then is that the best of the afternoon light is illuminating the sides of the aircraft with the over-wing steps.

Outdoor Monuments and Memorials 2

Kumagaya memorialShown top left and bottom right in this selection of vintage photos on display is the monument erected to commemorate the visit made by the Showa emperor in 1938. The monument bears the name Miizugahara, the name of a place that is now part of the city of Kumagaya. As you would expect, the memorial remains in place to this day. The other photos show Kumagaya Flying School as it looked when opened in 1935.

Kumagaya ArawasiDedicated to the arawashi (“wild eagles”), the moniker given to Japanese pilots in general during the Pacific War, this memorial is located further down from and on the same side of the road as the base collection aircraft. Thousands of young eagles left the nest that was Kumagaya during its time as a training establishment, so survivors built the monument in May 1975 to comfort the spirits of
the pilots lost in battle and to convey their story to the generations that followed.
The monument is inscribed with words written by IJAAF officer Michio Sugawara (1888–1983),
who attained the rank of lieutenant general. Dated March 1999, the stone lanterns on
either side were added by the monument’s preservation association.

Getting There

The closest railway station to Kumagaya AB is Kagohara on the Japan Railway (JR) Takasaki Line, which can be reached in about an hour from Ueno Station in Tokyo. From the south exit of the station it’s only a 20-minute walk along pleasantly wide streets laid out in a grid pattern to the main gate.

In the run up to the festival, the base website provides a more detailed map (shown in the poster at the start of this report) than what normally appears at:

Location Report 4

Aircraft Division, ShinMaywa Industries, Ltd.
Konan Plant, Kobe, Hyogo Prefecture
February 19-20, 2014

us-1a titleCascades of water gushing from its nosewheel well, JMSDF ShinMaywa US-1A rescue amphibian 9089 gets airborne from the sea off Kobe. The interesting, curtain-like “shock wave” effect is caused by the aircraft’s boundary layer control (BLC) system.

For the second time in six months, J-HangarSpace was in the fortunate position to be invited to ShinMaywa’s Konan Plant. On this occasion, people’s attention and camera lenses were focused on a rare spectacle: the final manufacturer test flights scheduled for one of the JMSDF’s two remaining US-1A rescue amphibians.

Kobe Revisited

As described in Location Report 1, J-HangarSpace’s August 2013 visit to ShinMaywa’s Konan Plant was very informative on the one hand but something of a disappointment on the other. Informative in that the large group from the Japan Aviation Journalists’ Association (JAJA) was granted privileged access to the main attraction, the second prototype US-2 rescue amphibian; disappointing in that the aircraft remained immobile due to flight instrumentation problems.

Once again kindly organized through the JAJA, this second visit was worked around the test flights that follow the culmination of an aircraft’s periodic maintenance check (progressive aircraft rework, or PAR, in JMSDF parlance). In this case, the check procedures had been carried out on the penultimate US-1A (9089), one of only two that remain in service.

9089’s Days Are Numbered

The event was billed as the last time this particular aircraft would be returning to its birthplace in Kobe. Having been accepted for service by the JMSDF on December 15, 2001, 9089 is planned to be retired later this year. Then the only aircraft of the type remaining in service will be 9090, the last of the 20 US-1/US-1As built and an aircraft that amazingly marked only the ninth anniversary of its handover on February 22.

Six months or so after 9090’s final PAR overhaul next year, personnel from the 71st Fleet Air Squadron at Iwakuni, Yamaguchi Prefecture, will follow tradition by decorating the aircraft’s bow with a hand-made garland and conduct a farewell ceremony. The US-1A will then disappear from Japan’s skies.

Seize the Day(s)

As the testing was geared to returning the aircraft in question to service as soon as possible, the aircraft’s interior was declared out of bounds on this occasion. More than compensating for the denied access, over two days two somewhat smaller JAJA groups were given the opportunity denied them back in September, namely to witness and photograph the aircraft taking off from and landing back on the sea off Kobe. J-HangarSpace was in the fortunate position to be able to book very reasonably priced direct flights with Skymark Airlines from Tokyo’s Haneda Airport and to stay for the both days, just in case.

The JAJA groups were once again met at the Konan Plant’s main gate by ShinMaywa test pilot Yoshimasa Miyamoto. On the first morning, the visitors arrived just in time to witness the aircraft undergoing engine runs in a pen screened on two sides close to the Konan Plant’s slipway. Having become accustomed to seeing slightly worn-looking US-1As in unit service—despite rigorous cleaning operations, the saltwater environment, the aircraft’s main engine exhausts as well as the boundary layer control (BLC) airflow outlets take their toll on the paintwork—it made a change to observe a shiny, in effect factory-fresh example. After stopping briefly at the test flight crew’s office overlooking the apron and donning the mandatory hard hats, the group was escorted down to watch the aircraft being towed around to face the slipway.

Swell Party

Then it was all aboard a boat to head out to sea, accompanied by another vessel, to be in position well ahead of the aircraft’s planned departure time. It being February, weather conditions could best be described as bracing, but both days were fortunately sunny and clear.

The boat carrying the JAJA group was equipped with several smoke flares, which when deployed on the surface of the water can burn for 15 minutes to mark the sea lane and show the flight crew the wind direction.

It was some time before the small dayglo dots that were 9089 could be picked out against Kobe’s industrial shoreline. Naturally in constant radio contact, the ship’s captain manoeuvred his vessel to be alongside the sea lane selected for takeoff.

Also present was local aviation photographer Takahiro Nakano, who provided J-HangarSpace with some invaluable tips on how to photograph from a pitching and rolling boat out at sea.

In command of the aircraft on both days was another company pilot, Shotaro Mori, whose JMSDF squadron career was spent entirely on ShinMaywa types. Having passed a test pilot course to be involved in the US-1A’s development with the 51st Fleet Air Squadron at Atsugi, Kanagawa Prefecture, Mori served with the 71st at Iwakuni for around four years before leaving the JMSDF to take up his current position. Messrs. Miyamoto and Mori were the two pilots at the controls for the maiden flight of the then US-1AKai (the prototype US-2) in December 2003.

The coverage for the remainder of this location report takes the form of a photo commentary, using images from both days divided into six phases of the flight.

(1) Prior to Engine Start

US-1A 9089 with tugThe imposing star of the show is towed by a tug toward the slipway. The 19th US-1/US-1A to enter service with the JMSDF, 9089 was taken on charge in December 2001. For comparison,
the first US-1, 9071, was handed over in March 1975, converted to US-1A
standard in 1981, and struck off charge as long ago as January 1986.

US-1A on slipwayThe aircraft at rest just short of the slipway, photographed from the boat carrying the JAJA group. Before moving onto the slipway, the outboard engines are put into reverse thrust to control forward motion. Moored to the right of the slipway is the speedboat that serves the same function as the
“follow me” car at airports.

(2) Taxying Out

US-1A engine runupAs there is a need to check the engines’ power and responsiveness out on the water, where brakes are inoperative, the flight crew does this when snaking their way out toward the takeoff point.

US-1A noseShinMaywa test pilot Shotaro Mori glances across at the boat carrying the ShinMaywa takeoff preparation team and the visiting journalists’ group. (The plume of smoke that seems to be
coming from the rear of the cockpit is from a factory chimney on the shore!)

US-1A panelsThis view shows the open intake doors on top of the main wing. The circular intake with its flap open on the port side and the rectangular flap opening on the starboard side provide air for the BLC engine and the auxiliary power unit (APU), respectively.

US-1A water taxyMaking a striking image against the sun-dappled sea, the aircraft is slowly taxied to the takeoff point. Depending on the wind direction, one or other wing float will be in contact with the surface of
the water when taxiing in this configuration.

US-1A close-upThe mast atop the hull nose houses the oscillators for the angle of attack and turn-and-slip indicators. Jutting out from the mast is the crossbar known as the kanzashi (ornamental hairpin), which comes
into its own for landing. When aligned with the horizon at 500 feet, this simple device makes the
required angle of 6.5 degrees. Just visible to the left and right of the mast are the pitot tubes.

(3) Takeoff

US-1A takeoff(1)Like any flying boat, the US-1A amphibian makes an impressive sight in its element out on the water. Thanks to its BLC system, the aircraft is capable of taking off at a mere 50 knots.

US-1A takeoff(2)
(Above and below) On climb out, the aircraft’s flaps are set to 40 degrees at 70 knots and to 20 degrees at 100 knots, when the BLC setting is moved to idle. The flaps are fully raised and the BLC finally switched off when 130 knots has been attained.

US-1A takeoff(3)

(4) Landing

US-1A landing(3)On the point of touchdown, the smoke flare is visible on the surface of the water to the left. Immediately prior to touchdown the aircraft is configured with 60 degrees of flap, height 50 feet, speed around 50 knots and a nose-up attitude of 6.5 degrees. Unlike normal aircraft, the US-1A seems to
land gently in slow motion.

US-1A landing(4)No use is made of propeller reverse thrust immediately after landing. Experiments were conducted into the possibility in the case of the US-1A’s predecessor, the PS-1 patrol aircraft. Although this technique did have the effect of shortening the distance across the water, there was a fear that the spray
produced by the technique would damage the engines or propellers. As a result,
the technique was never used operationally.

US-1A landing(5)After touchdown the flaps are raised and the BLC engine is set to idle. When the hull bites into the water, the aircraft very quickly turns into a boat.

(5) The Long Taxi Ride Home

US-1A off KobeBeautifully lit by the afternoon sun, 9089 is slowly taxied back to the Konan Plant.
The aircraft had returned from a visit to Iwakuni, where shimmy tests were
carried out as part of the post-PAR procedures.

US-1A lowering undercarriageThe flight crew lowers the undercarriage prior to approaching the slipway. The undercarriage’s mechanism is of a very complex design to retract the wheels into a narrow bay yet for them to
be set sufficiently wide apart when extended.

(6) Back on Terra Firma

US-1A on slipwayIts undercarriage making waves and the propwash rippling the water’s surface, 9089 mounts the Konan Plant’s slipway. This rare sight can usually be witnessed at the annual air show at JMSDF Omura
in Nagasaki Prefecture. The arrival of a ShinMaywa aircraft that then uses the slipway, which
dates back to Imperial Japanese Navy times, traditionally forms one of the show’s highlights.

US-1A on slipway(2)A ShinMaywa ground crew member gives the thumbs up sign as the pilot slowly edges the aircraft forward onto the apron at the Konan Plant.

US-1A hose down
(Above and below) Two views of the aircraft during and after its post-flight wash down. As the Konan Plant lacks the automatic equipment embedded in taxiways at operational JMSDF bases, this
procedure has to be done by hand with hoses.

Awaji to Kobe on the mainland.

J-HangarSpace would like to extend thanks to all concerned at ShinMaywa and the Japan Aviation Journalists’ Association for granting such a rare opportunity.

The Awaiting Fate?

us-1a 9088Having officially entered JMSDF service in March 2000, US-1A 9088 was engineless in a hangar at Iwakuni in September 2012. Now that 9088′ s flying days are over, only two aircraft of the type
remain operational.
Wishful thinking on the part of one JAJA member hoped that ShinMaywa
would splash out on some kind of permanent structure at the Konan Plant in which to
house a US-1A for posterity.

JGSDF Asaka Training Area
Asaka, Saitama Prefecture
October 27, 2013

J-HangarSpace was gratefully fortunate to obtain a ticket to witness the spectacle that is the annual review of Self-Defense Force (SDF) troops. Held on what was a glorious sunny day, this year it was the turn of the Japan Ground Self-Defense Force (JGSDF) to stage the event.

Event History

The first postwar review was held at what was then the Etchujima base in Tokyo in 1951—the year after the establishment of the National Police Reserve—and thus pre-dates the founding of the Self-Defense Forces. A ceremony that took place in front of the capital’s Meiji Memorial Picture Gallery in 1955 marked the first anniversary of the founding of the then Japan Defense Agency; this ceremony remained a fixture in the events diary until 1972.

flagasakaAll present stand for the raising of the national flag at the 2013 SDF troop review.

Ostensibly out of car parking and transport link considerations, the ceremony was moved to the Asaka Army Camp facility in 1973. Aside from 1988, when the Showa emperor died, and years in which there were large-scale disasters, this practice continued for the following eight years.

From 1996, the hosting military arm has followed a JASDF, JMSDF, JGSDF sequence, the latter missing its turn in 2001 as a result of the terrorist attacks against the United States. Favoured venue for the JASDF has been the hardly convenient Hyakuri AB out in Ibaraki Prefecture; in the case of the JMSDF the venue of choice has been Sagami Bay.

Acting as government host at this year’s event was Defense Minister Itsunori Onodera, who was appointed in December 2012. Prime Minister Shinzo Abe (pictured above) reviewed the 4,000-odd troops from a moving car before delivering a keynote speech from the main stand. As would be expected, security was tight both in and around the venue; police in riot gear had been positioned at every junction on the approach roads to the base.

Prime Minister Abe delivers his speech.

In the space of about 90 minutes, a well-orchestrated and practiced sequence—rehearsals had been conducted on two previous days—saw serried ranks of SDF elements leave their initial parade positions to form at one end for the mass march past. These were followed by convoys involving around 240 military vehicles. The only change to the published programme (cover shown at top of this report) was the cancellation, due to the strong wind, of a parachute jump by airborne troops that had been planned to follow directly after the prime minister’s speech.

ffosOf aviation-related interest among the vehicles was this truck carrying the Fuji Heavy Industries-developed Forward Flying Observation System (FFOS). Having first entered production in
2003, these helicopter-based unmanned aerial vehicles are operated in conjunction with
artillery units. Another example is seen below in a hangar at Kisarazu Army Camp.

Aviation content comprised a 50-aircraft flypast, led by formations of JGSDF helicopters by dint of hosting rights and their slower speed. Reported in the Japanese press as numbering around 20,000, spectators were mainly seated in long grandstand structures, positioned on either side of the parade ground and affording panoramic views. J-HangarSpace’s vantage point low in one stand opposite and to one side of the main stand was directly underneath the aircraft flight path, which was fortunately into the sun.

asakaf-15sA trio of F-15J Eagle fighters from the 305th Squadron based at Hyakuri, the JASDF’s preferred venue when hosting the review ceremony.

Following the lowering of the national flag and a salute in his honour, Prime Minister Abe departed. A supplementary programme of events, which included equipment displays and marching bands from the U.S. armed forces, kept the public entertained until the official closing time of 3 p.m.

That same afternoon, Prime Minister Abe changed from formal wear into more suitable garb before flying in a JGSDF Chinook helicopter to Izu-Oshima, one of the islands in the Tokyo-administered Izu chain around 100km south of the capital.

The island had borne the brunt of a typhoon 11 days before, and the resulting heavy rain and landslides had tragically claimed the lives of 31 islanders. In contrast to the spic and span precision of the review ceremony, JGSDF personnel had been heavily engaged in getting their hands dirty in the unenviable task of searching for those still missing and assisting in the clean-up operations, areas of expertise in which SDF personnel from all three services have gained more experience than they would have liked in recent years. Abe had made mention of the events on Izu-Oshima and paid tribute to the SDF’s tireless efforts at the start of his speech at Asaka.

Although come next October it should again fall to JASDF personnel at Hyakuri AB to host the event, it remains to be seen whether the 60th anniversary celebrations prompt a break with tradition.

Location Report 2

Gunma Heliport
Maebashi, Gunma Prefecture
September 14, 2013

Gunma HeliportGunma Heliport’s main terminal and administrative buildings feature distinctive yellow aerofoil designs on their roofs.

About an hour and a half by a bullet and local train north from Tokyo, the Gunma prefectural capital of Maebashi accounts for 340,000 of the administrative area’s total population of around two million.

Its name literally meaning ‘herd of horses’, Gunma is well known for agriculture and its history of sericulture. The Japanese aviation name most closely associated with the prefecture is that of Chikuhei Nakajima (1884–1949), who was himself from a local farming family. From humble beginnings in a shed that had been used for silkworm breeding in Ota, eastern Gunma, what became the Nakajima Aeroplane Company on April 1, 1918, went on to operate two plants in the prefecture, at Ota and Koizumi (now Ooizumi). The former site is now home to a plant belonging to Fuji Heavy Industries, Ltd., the Nakajima company’s postwar successor that produces cars under the Subaru brand name there; the latter houses Panasonic Group subsidiary Sanyo Semiconductor Co., Ltd.

The third public facility of its kind in the country, Gunma Heliport at Maebashi opened its doors on August 25, 1988, and is thus celebrating its 25th anniversary this year. In accordance with the designated administrator system included in a revision to the Local Government Act, the heliport has been under the management of a consortium made up of Japan Airport Consultants Inc. (JAC) and Taisei-Yuraku Real Estate Co., Ltd. since November 2007.

Taking a bus bound for Tamamura Town Hall from stop 4 on the north side of Maebashi station, Gunma Heliport is located about a five-minute walk from a bus stop of the same name. Covering 42,000 square metres (10.3 acres), the heliport has spaces marked out for seven helicopters on its apron; its operating hours are 0700–1900. It is equipped with a 55 metre × 30 metre (180 feet × 100 feet) landing strip and a 25 metre × 20 metre (82 feet × 65 feet) landing pad that can cater for helicopters up to the 9-ton class.

Aviation Day posterA poster on a Gunma Heliport terminal building window advertises the events planned for Sora no Hi in the facility’s 25th year of operation.

J-HangarSpace’s visit coincided with festivities marking Sora no Hi, the generic name given to a wide range of aviation-related events held primarily at airports across Japan. Literally meaning Sky Day, Japanese sources still tend to use the previous Aviation Day, from Kokubi, when referring to such events in English. The Japanese name was changed in 1992, the 40th anniversary of the resumption of postwar civilian flying in Japan, from when the period September 20–30 has been known as Air Week.

Events planned during and around this period date back to the air pageant that took place at Tokyo’s Haneda Airport on September 28, 1940, to mark the 2,600th anniversary of the accession to the throne of Japan’s mythical founder, Emperor Jinmu, and the 30 years since the first successful flights in Japan made in heavier-than-air aircraft. (See the first entry on this website’s Japanese Aviation History page: click here) The following year, although the date itself had no special significance, the aviation authorities designated September 20 for a second Aviation Day, only for political events to intervene. Interrupted by the war and the postwar ban on flying, it was to be September 20, 1953, before Aviation Day could be resurrected.

Although on a lesser scale than other venues, Gunma Heliport’s six-hour Aviation Day schedule was a major attraction; a record-breaking 3,012 local residents attended. Aside from giving some of them—lucky lottery winners and paying passengers—their first experience of flight in a based operator’s helicopter, the Maebashi event gave the two resident units the opportunity to put their respective machines through spirited displays.

A hangar at the east end of the apron houses the Bell 412EP JA200G (‘G’ for Gunma and ‘200’ from the prefecture’s two million population, ‘200 ten thousands’ in the Japanese way of counting) belonging to the Gunma Prefectural Disaster Prevention Aviation Unit. Acquired for a then equipped price of around 700 million yen and handed over on May 20, 1997, the aircraft is called Haruna after Mount Haruna, a dormant volcano that lies within the prefecture. (An Imperial Japanese Navy [IJN] battleship and a now decommissioned class of JMSDF destroyer have also shared the name.)

Gunma Air Rescue, as they are known in English, share the heliport with the Gunma Prefectural Police Aviation Unit’s eight-seater Agusta 109E Power JA01GP, which is kept in a hangar adjacent to the terminal building. Like its predecessor, a Bell 206L-3 LongRanger, JA01GP is named Akagi, as Haruna after a local mountain. (Likewise, Akagi was also the name of an IJN ship, an aircraft carrier, in World War II.)

The A109E offers the benefit of more rapid response times to cover incidents within Gunma, for which centrally located Maebashi makes an ideal base. The Oze marshlands to the far northeast of Maebashi are less than 20 minutes’ flight time away, the city of Tatebayashi only 11 minutes to the southeast.

Details of the operations and equipment of these two units, and others like them, are planned for inclusion on their respective pages of this website.

ShinMaywa hangar The second prototype Shin Maywa US-2 search and rescue amphibian is dwarfed by the cavernous hangar at the company’s Konan Plant in Kobe, August 29, 2013.

Representative of this website’s planned content, the first J-HangarSpace location report comes to you from ShinMaywa’s main plant in Kobe, where each of the company’s postwar family of JMSDF aircraft—the PS-1 anti-submarine warfare (ASW) flying boat and the US-1/US-1A as well as US-2 search and rescue (SAR) amphibians—has been developed and manufactured.

J-HangarSpace joined a tour organized by the Japan Aviation Journalists’ Association (JAJA) to gain more of an insight into the company and the US-2, the second prototype of which was present in the hangar.

Background to Konan Plant

Squeezed in between the main highway connecting Kobe with Osaka and the edge of Kobe Bay, the Konan Plant is located close to Ashiya station on Japan Railway’s Kobe Line. The plant’s operations date back to 1942 and the era of Kawanishi Aircraft Company Limited, ShinMaywa’s famous predecessor. From before the Pacific War, Kawanishi’s operations had centered on the manufacture of floatplanes and flying boats, culminating with its Type 2 Flying Boat (Emily), 167 of which were built here. A close look at the front of the hangar reveals the patches covering the holes made by a marauding U.S. Navy F6F Hellcat pilot in the closing stages of the war.

In the immediate postwar era, the Allied Occupation authorities imposed a ban on aircraft manufacture that was to last until April 1952. Founded in 1949, Shin Meiwa Industry Co., Ltd. (the name was anglicized to ShinMaywa in 1960) turned Kawanishi’s technological skills to the production of motorcycles and dump trucks. Soon after the outbreak of the Korean War in June 1950, the company received contracts to manufacture drop tanks for U.S. Air Force aircraft and moved on to overhauls of the nascent Japan Air Self-Defense Force’s Sikorsky S-51 helicopters from September 1954. Nowadays, the company is responsible for overhauling JASDF U-4 (Grumman Gulfstream IV SP) and JMSDF U-36A (Learjet 36A) aircraft.

A Hitachi Group affiliate company from 1960 to 2004, the company’s history of diversification persists to this day. Including special-purpose truck bodies, car parking systems and passenger boarding bridges for airports, its current product range extends across four other business divisions.

In the 1960s, the Konan Plant carried out overhauls of the U.S. Navy’s Pacific-based fleet of twin-engined Martin P5M Mariner patrol seaplanes, a type that bears a certain similarity to the Japanese designs. The company’s wealth of experience in the design and manufacture of flying boats made it the ideal contractor for the task. To this day, the plant features a slipway located a short distance away from the apron in front of the main hangar; aircraft can thus undergo on-the-spot water taxying and flight trials.

The Konan Plant’s 116,725 square metre (29-acre) area is roughly three times the size of the local Hanshin Tigers baseball stadium. These days, much of the plant is devoted to the manufacture of composite material components for Airbus and Boeing airliners. Employing a workforce of just over 1,000 people, the Aircraft Division also operates plants at Takurazuka in Hyogo Prefecture (for component assembly) and at Tokushima on the island of Shikoku.

Highly Qualified Host

The factory tour group were honoured to have as principal host none other than ShinMaywa test pilot Yoshimasa Miyamoto. Born in Kyoto in 1949, he was assigned to Iwakuni in Yamaguchi Prefecture after graduation from the JMSDF’s Naval Academy in Etajima, Hiroshima Prefecture. Miyamoto’s career path followed exclusively the progression of ShinMaywa types with the 31st Fleet Air Group’s 71st Fleet Air Squadron at Iwakuni. He had amassed around 2,800 hours on the PS-1 and 6,000 hours on the US-1/US-1A by the time of his retirement from the JMSDF, when he joined ShinMaywa as chief test pilot on the US-1AKai (Improved) programme, the designation by which the US-2 was originally known.

Miyamoto introduced a JMSDF-produced video that ran through a typical US-2 SAR mission and the technology that lies at the crew’s disposal. This includes a retractable Mitsubishi Electric forward-looking infra-red (FLIR) camera mounted on a swivel turret in the port side of the nose, the feed from which can be displayed directly in front of the pilots.

In the video, a co-pilot who had formerly flown the P-3C Orion was still coming to grips with landing on the shifting sea instead of a firm runway. To assist transitioning pilots, Iwakuni operates a US-2 simulator that J-HangarSpace briefly “flew” last year, finding the visual system very rudimentary in comparison with airliner simulators. A ShinMaywa engineer said that budgetary constraints would not have permitted anything other than the bare essentials.

US-2 Development Priorities

Hideyuki Mochida, a manager in the ShinMaywa Aircraft Division’s Engineering Department, kindly provided the attendees with an overview of the US-2’s development from the US-1A.

Although only seven years had separated in turn the 1967-vintage PS-1 from the US-1 (1974) and US-1A (1981), some 15 years had passed when development of what was to become the US-2 was commenced in 1996. Another six years were to elapse before the first prototype’s completion on November 28, 2002.

Taking into account the advances in technology that had been made in the ensuing period, the engineers’ brief ultimately led them to focus on implementing improvements in three principal areas:

(i) Handling when taking off or landing on water
Fly-by-wire technology with manual backup was adopted for the flight controls and “glass cockpit” instrumentation installed.

(ii) The on-board environment for patients
A pressurized cabin was introduced, enabling higher altitude ferry operations.

(iii) Open-ocean rescue capabilities
The US-1A’s four 3,400shp Allison T64 engines, licence-built in Japan by IHI, and three-blade propellers were replaced by 4,591shp Rolls-Royce AE2100Js driving six-blade Dowty units.

US-2 cockpitSeen from the co-pilot’s seat, the captain’s dual-screen glass cockpit follows the standard configuration of primary flight (left) and navigation displays. Centrally mounted are the large-screen engine (top) and systems displays. To the lower left of the latter, which also shows checklists, is the flight control display that provides rudder angle and trim status information. Although some pilots are qualified to fly both the US-1A and the US-2, they tend to be assigned to operate only one of the types due to the inherent differences in the cockpit instrumentation and flight control systems.

US-2 propsThe US-2’s Dowty R414 propellers are 4.12m (13.5 ft) in diameter and each weighs 393kg (around 870lbs), making them smaller but heavier than those fitted to the US-1A.

The aircraft’s fifth engine, a vertically oriented Honeywell/Rolls-Royce CTS800-4K helicopter engine embedded in the upper fuselage aft of the main wing, has been retained to provide power solely to the boundary layer control (BLC) system. Blowing air over the aircraft’s rudder, flaps and elevators plays a major part in reducing the aircraft’s takeoff and landing speed from that of a normal aircraft, which at 300 km/h (185mph) equals that of a bullet train, to that of a car (around 90km/h, 55mph). In passing, it was mentioned that the US-2 is not equipped with an anti-skid system for landings on wet or icy runways.

Overall, the improvements made resulted in the US-2 being able to reach a search area more quickly and loiter on station longer. The aircraft’s maximum radius of operation with two hours spent on station was extended to 1,000 nautical miles (1,850km), a 25% improvement on that of the US-1A. At a landing weight of 43 tons, the aircraft’s extremely low landing speed characteristics allow it come to a gently bobbing halt after only 330m (1,080 feet) on the ocean, from which takeoff can be achieved in 280 metres (920 feet). To cap it all, depending on the length of the waves, the US-2 is also uniquely capable of operating in ocean swell up to 3m (10ft), around double a flying boat’s normal operating limit.

Design Comparison

A walk around the second prototype allowed a closer look at the changes made to the US-1A’s external appearance to arrive at the current version. The US-1A’s nose underwent some cosmetic surgery to make the US-2’s radome that much smaller, and the earlier aircraft’s oversized sensor antenna positioned directly in front of the cockpit was deleted. The US-2 also lacks the canted fences that had to be installed atop its predecessors’ engine nacelles to rectify a marked propwash-induced sideslip. Whereas the fuselages of the earlier aircraft ended in a tail cone, from which protrudes a refueling inlet, the US-2’s fuselage has been shortened and ends flush with the trailing edge of the rudder. More subtle changes involved smoothing out the fuselage line aft of the cockpit and the hull fairing aft of the wing as well as enlarging and repositioning further forward the bulged window on each side of the forward fuselage.

A close look at a photo of the port side of the dorsal fin of a US-1A will reveal a round grille opening within the yellow stripe. Omitted from the US-2, this houses a speaker, via which the pilot or co-pilot can be in vocal contact with persons being rescued while circling above or after landing.

The decision to install cabin pressurization along two-thirds of the cabin length resulted in exhaustive efforts to save weight elsewhere. Including the use of alloy materials for the wing floats and titanium for parts of the main undercarriage and the front panel of the spray suppression device, these efforts resulted in the trimming off of 600kg.

The US-2 retains two examples of ShinMaywa’s proprietary expertise in the field of hydrodynamics that were featured on its predecessor and are instrumental in its ocean landing and takeoff performance: the U-shaped groove-type spray suppression device wrapped around the nose that channels the water flow downwards, and a pair of convex-shaped spray spoilers that have been fitted under the fuselage to then direct the water flow sideways. The latter minimize the likelihood of an engine ingesting salt water or that the propellers and wing will sustain wave damage. Interestingly, upon its return from an over-water mission, a US-2’s engines are stopped and the aircraft pulled by a tow-truck through a water spray system embedded in a taxiway to blast off any salt deposits; the standard anti-corrosion procedure for a P-3C Orion patrol aircraft is to be slowly taxied under its own power through the jets of water.

US-2 headonCombined with its low landing speed, the US-2’s narrow boat hull lessens the impact of ocean landings. This imposing head-on view shows the multiple attachment points of the groove-type spray suppression device to good advantage. Known as the nose pendant, the rope on the nose is used for mooring purposes in conjunction with the anchor stowed on board.

US-2 9902J-HangarSpace had been hoping to make a major splash with close-up shots of 9902 on takeoff from and landing on Kobe Bay; unfortunately, technical hitches on the day dictated that she never moved an inch, let alone got her feet wet.

US-2 undercarriageThe US-2 amphibian’s mainwheels and complex retraction mechanism are a far cry from the single wheel units of its ‘grandfather’, the PS-1 flying boat. As the latter was not designed and did not have the capability to land on runways, its mainwheelsakin to built-in beaching gear—were actually the
same as those fitted on the Lockheed F-104J Starfighter.

US-2 Programme Status

December 18, 2013, will mark the 10th anniversary of the first flight of the ShinMaywa US-1Kai (US-2). Including the two prototypes, five* are currently in service with the JMSDF alongside two of the US-2’s predecessor, the US-1A. Plans call for a total fleet of 14 US-2s and the retirement of the last of the US-1As when they achieve their airframe flight hour limit, which will likely occur within the next four years.

The Konan Plant undertakes the final assembly of a “Tamiya kit” of major assemblies and components provided by the participation of around 1,500 companies. Shin Maywa itself produces the radome, forward section of the boat hull, nosewheel undercarriage and door, main undercarriage, wing floats and rear fuselage. As tends to be the case, other famous names in Japan’s aviation industry have a stake in the production of other major sub-assemblies, which are transported by road to Kobe. Prominent among the other suppliers are:

Company Name Major Assemblies
Kawasaki Heavy Industries (KHI) Cockpit and pressurized section of forward fuselage; centre section of the main wing; vertical tail
Mitsubishi Heavy Industries (MHI) Outer sections of main wing, rear sections of engine nacelles, horizontal tail assembly, rudder
NIPPI Corporation
(KHI subsidiary)
Wave suppression device; fuselage-side undercarriage bulges; rear fuselage door; forward sections of engine nacelles; forward and aft main wing fairings; wing slats, spoilers and inner/outer flaps; dorsal fin

If all goes according to plan the Konan assembly line will see unprecedented activity, as the US-2 is in line to become the first civil version of an SDF aircraft type to be exported. Involving the thrashing out of an offset agreement, negotiations are still under way with the Indian government. In the meantime, ShinMaywa will be building the sixth US-2 under a 12.3 billion yen contract awarded under the fiscal 2013 budget.

The latter part of ShinMaywa’s presentation focused on the aircraft’s much-touted but cost-prohibitive civil application as a water bomber, a plan that dates back to June 1976, when drop trials were carried out at Iwakuni with the suitably modified first prototype PS-1 ASW aircraft. An ideal but technically challenging solution would be for the JMSDF to operate a small number of quick-change versions of the aircraft, although a suggestion from the floor was for US-2 operations to be progressively handed over to the Japan Coast Guard, as they were no longer best suited to the JMSDF’s remit.

J-HangarSpace’s visit was to have included boarding a boat to witness the second prototype’s last test flight before being handed back to the JMSDF for service with the 71st Fleet Air Squadron at Iwakuni. Sadly, technical problems meant that the flight had to be postponed to a later date.

Photo Gallery: US-2 Interior

As the second prototype was at the end of a flight test programme, during which additional technical data was gathered, its on-board equipment fit was in the process of reverting back to that of the production aircraft. Working backwards from the flight deck, these images thus give a fair representation of an operational aircraft’s interior, though layouts do vary depending on the type of rescue mission being conducted. If the need arises, up to 30 passengers can be accommodated, or 11 stretchers when in dedicated rescue configuration. As an airlifter, the US-2 can carry a maximum payload of 3 tons.

The flight deck extends up to frame 11, the accommodation quarters from there to frame 24 (a distance of 13m [42.6ft]), and the crew room between frames 24 and 31, the latter marking the end of the pressurized cabin area.

Flight Deck

US-2 flightdeckThe intense glare of the sun through the windscreens made it difficult to include the overhead panel in this general view of the flight deck.

US-2 copilotseatThe co-pilot’s nosewheel steering control can be seen to the immediate right of the control column. Changes of direction up to a maximum of 60 degrees to the left or right are possible.

US-2 escapehatchThe port overhead cockpit escape hatch had been lowered to provide additional ventilation on what was a baking hot day in Kobe. Giving the aircraft a just moved in look, many of the seats were
protected by grey covers, most of which had handwritten marks showing their designated positions.

Accommodation Quarters

US-2 tourShinMaywa personnel show the JAJA group around the US-2’s flight deck and still spartanly appointed accommodation quarters. Configurations vary, but the US-2’s accommodation quarters are normally configured with foldable, inward-facing troop seating arranged along the port side and stretchers
on the starboard side.

US-2 floorhatchThe hatch leading down to the nose compartment had been ‘invitingly’ left open.

US-2 sidehatchThe escape hatch next to the starboard observation stationlocated midships, beneath the leading edge of the main winghad been removed and placed on the seat.

Crew Room

US-2 crewroomThe crew room area, looking back from the accommodation quarters. The far door, forward of the orange seat, marks the end of the pressurized cabin.

US-2 station1A US-2’s crew complement varies but usually numbers 11: two pilots, two flight engineers, an SAR coordinator, an electronic sensor operatorwhose station, shown here, is on the starboard side
of the crew room
two flight medics and a three-man rescue team, including a JMSDF diver.

US-2 station2The SAR coordinator’s seat is located on the port side of the crew room.

Nonpressurized Operations Deck

US-2 crewstation3Only two-thirds of the length of the cabin is pressurized, so this seat on the opposite side to and a little forward of the main fuselage door lies outside that zone.

US-2 craftsmanshipShinMaywa craftsmanship is seen in this exposed section of fuselage opposite the main fuselage door.

US-2 maindoorIncorporating a collapsible seat in its stowed position, the cargo-like main fuselage door opens inwards and is slid sideways and locked in position to maximize space. In a rescue situation on the high seas, rapidly deploying the inflatable, outboard motor-powered rescue dinghy in the confined space
available demands precise and practised teamwork.

US-2 rearinteriorThe area at the very rear contains more seating and stowage space. The black ducting running along the centre of the cabin roof forms part of the BLC system.

Parting Shots

US-2 noseThis view clearly shows the strake-like, convex-shaped spray spoiler, which directs the water flow sideways, located on the underside of the boat hull just aft of the red propeller warning stripe.
The lines radiating down from the bulged side window are used according to the surface
wind speed when air-dropping supplies. From the left, each pair of red and yellow
stripes represents a 10-knot increase in wind speed, starting with 0 knots.

ShinMaywa shopfloorThe JAJA group was shown a small but key part of the Konan Plant. If the Indian contract negotiations are successfully concluded, this assembly hangar will again be bustling with activity.
