JMSDF Squadron Histories & Markings Part 2

Following the pattern of the front-line squadron history pages, the following listing of JMSDF support units appears in numerical order by Fleet Air Squadron (FAS). Note that these do not include entries for the flights into which these squadrons are in some cases divided.

Fleet Air Squadron (FAS) Listing

51st 61st 71st 72nd 73rd 81st 91st

To recap, the relevant fleet air wings (FAWs) were formed as follows:

21st FAW Sept. 1, 1961 (Tateyama) 22nd FAW Dec. 1, 1987 (Omura) 31st FAW Mar. 1, 1973 (Iwakuni)

The seven squadrons covered on this page run from the JMSDF’s test and airlift units via what used 
to be its trio of search and rescue squadrons to those engaged in special missions.

51st FAS

Formed  Sept. 1, 1961 (P2V-7/S2F-1, 2nd FAW, Hachinohe)
Current Base  Atsugi (511th Flight [P-1/UP-1, P-3C, UP-3C];
                    513th Flight [SH-60J/K, USH-60K])

The 51st FAS was formed primarily as an aircraft and equipment test and evaluation unit flying six P2V-7s (511th Flight) and six S2F-1s (512th Flight) with the 2nd FAW at Hachinohe in September 1961. Organized into three flights with the 514th Flight and placed under the 4th FAW on March 15, 1963, the squadron moved to Shimofusa early the following month, on April 3, 1963.

The unit also operated the T-34, presumably for liaison rather than test flights, from at least the summer of 1965 (link) to late 1981, as evidenced by this photo from December 1968 (link)

The 513th Flight was added in March 1968 to accommodate the arrival of the first helicopters, three Sikorsky HSS-2 Sea Kings and two KV107-IIs. The Tracker-equipped 512th Flight disbanded upon completion of its development work on December 20, 1971.

In the meantime, on May 14, 1970, two HSS-2 crews had narrow escapes when their aircraft came into contact during training at Shimofusa. One aircraft (8024) rolled over, destroying its main rotor, and the other (8018) belly landed, but the total of nine crew members suffered only minor injuries.

The second KV107-II3, photographed (above) during its time with the 51st, can be somewhat better seen in this image (link) from June 1968, being tested carrying an SNJ-5 (formerly 6175, marked as 3MSS-01 of the resident 3rd Service School) at Shimofusa.

Also at Shimofusa, on the last day of September 1963, the first KV107 (link) shows the overall colour scheme of the first two aircraft to have been the same as the Neptune in the background. Applied to the fourth aircraft when with the 51st, the by then standard two-tone colour scheme was on display, along with the unit marking, at a Shimofusa air show in the early 1970s (link).

Back on the fixed-wing aircraft front, a bunkentai (detachment) formed at Iwakuni on June 26, 1968, for the operational testing of the PS-1. This disbanded on March 31, 1983, its aircraft being transferred to the 31st FAS. Fortunately, the two PS-1 accidents suffered by the detachment resulted in no loss of life.

to the JMSDF on August 10, 1968, but was destined to be lost with all hands in an
accident at Iwakuni, when assigned to the 31st FAS in April 1983.

VSA Neptune JMSDFOne of the more unusual aircraft flown by the 51st FAS was the Variable Stability Aircraft (VSA), a
Kawasaki-modified P2V-7 that was used to evaluate fly-by-wire technologies from 1978 to 1980.
The aircraft then formed part of the test pilot courses until withdrawn from use in 1982.

Placed under the direct control of the Fleet Air Force from July 29, 1969, the main element of the 51st was relocated to its current base of Atsugi on October 31, 1981. Imported from the United States, the first three JMSDF Lockheed P-3C Orion’s arrived at Atsugi for initial testing and evaluation by the 51st FAS on Christmas Day that same year.

At the time of a visit by the now defunct Air World magazine in June 1998, the 51st’s flying units comprised the 511th Flight, conducting testing on three Orion variants (P-3C, UP-3C. UP-3D), and the 513th Flight, which at that time flew the HSS-2B Sea King and SH-60J. These flights remain operational and divided between current fixed-wing patrol and helicopter types today.

This HSS-2B was still on active duty with the 51st in May 2003. Way before, in September 1970,
HSS-2 8016 had been seen sporting the squadron marking on its sponson
(link), and HSS-2B 8097
took part in events at Atsugi in April 1994
(link). (Photo: Ken Fielding via Wikimedia Commons)

Although not wearing any tail markings, this HSS-2B at Tateyama in October 2002 was
at that time assigned to VX-51.

The 51st has been flight testing with production SH-60Js since August 1991. The aircraft (above) on
display at Atsugi in May 2000 bore a fuselage marking proclaiming the
513 Flight Unit of VX-51
as the pioneering
MIGHTY FLT. The example shown below was on strength in October 2014.

The unit will have raised its profile outside Japan following the deployment of one of its P-1s to Djibouti for operational testing via the United States and the Royal International Air Tattoo in the UK in July 2015.

Over the years, the 51st has also been given additional responsibilities, resulting in the formation of more than 30 sections, including those conducting investigational research, providing training guidance and running test pilot courses. From the flight operations standpoint, the unit is naturally called upon to contribute to relief operations when such pressing needs arise, most recently during the disaster relief operations carried out in response to the Kumamoto earthquake in April 2016.

during the emergency.

61st FAS

Formed  Dec. 20, 1971 (R4D-6, YS-11M/M-A, S2F-U, under
direct Fleet Air Force [FAF] command, Shimofusa, Chiba Prefecture)
Current Base  Atsugi (C-130R, LC-90)

The JMSDF’s dedicated transport and miscellaneous duties squadron, the 61st’s initial equipment was handed down from the 205th ATS (two R4D-6s, two YS-11Ms and a YS-11MA) and the 51st FAS (two S2F-Us converted from standard S2F-1s). Although formed at Shimofusa, when staffed by 25 officers, 32 petty officers and 23 seamen, the unit relocated to Atsugi just four days later, on Christmas Eve 1971, and has remained there ever since.

The first YS-11M completed its maiden flight on February 25, 1967, and was delivered to the 
JMSDF on the last day of the following month. Its last flight took place on
Boxing Day 2014.
(Photo taken at Atsugi, May 2000)

The second YS-11M first flew a year later, on February 25, 1968, was delivered on March 15 that
year and decommissioned 46 years later, in March 2014.
(Photo taken at Kisarazu, October 2012)

Based on the YS-11-100 series, the two YS-11Ms had been delivered in the same year as their first flights, 1967 and 1968, and the first 300/400 series-based YS-11M-A shortly before the 61st was formed, in November 1971. The 182nd and last YS-11 off the production line, a second YS-11M-A joined up on May 11, 1973, this differing in having had the freight door moved from the rear to the forward fuselage on the left side (link).

(Above and below) Two earlier photos of 61st FAS YS-11s taken at Kanoya 17 years apart, in
April 1977 and November 1994, respectively.

One of the four S2F-1s converted to S2F-U utility standard from 1970. The conversion work
included the removal of the radome, all anti-submarine warfare equipment and the
AVQ-2A searchlight from its underwing housing.
(Photo: JMSDF)

(Above and below) Delivered in 1958, the 60th and last Tracker to enter JMSDF service (4160)
was another of the four S2F-U conversions. In the manner of the US-2Cs operated by the
U.S. Navy’s VU-5
(later VC-5), the aircraft also towed targets for ship anti-aircraft
firing practice. Seen here at Iwakuni in May 1973, the aircraft was finished in the
variant’s standard multi-coloured scheme of Engine Gray fuselage and forward
engine nacelles with yellow-orange on the horizontal wing surfaces and on the
aft section of the engine nacelles. The vertical tail and chordwise wing stripes
were painted in red-orange (International Orange)
.

Following an evaluation of the conversion by the 51st FAS, the 61st operated a total of four S2F-Us for operations that included target-towing. The R4D-6s were retired in March and on October 30, 1972, during which time the third S2F-U was provided. The fourth and final S2F-U followed on March 31, 1973, and continued in service until the last of the type (9153) was decommissioned on August 31, 1981.

At a time when the Tracker was disappearing from frontline units, two converted to S2F-C transport standard were taken on strength, the first on October 22, 1974, the second in the following year. Passed to the 31st FAS around 1978, these saw something like six more years of service before themselves being decommissioned in the early 1980s.

From October to December 1979, the YS-11s were operated from Shimofusa and the Trackers from Kanoya while the Atsugi runway underwent repairs.

Used in the transport role from 1978, the JMSDF’s two S2F-C conversions had Insignia White upper
and Gull Gray lower surfaces. Not only the colour scheme but also the conversion work involved
was essentially the same as that of and for a U.S. Navy US-2B. Unlike the S2F-Us, the –Cs
retained their arrestor hooks, but note that the searchlights had also been removed. They
still bore their ‘61’ unit tail codes for a time even after their transfer to the 31st FAS.

Capable of carrying two crew and six passengers and offering somewhat more in the way of comfort than a Tracker, a B-65 (B65 Queen Air) was repurposed from navigation training with the 202nd Air Training Sqn to the personnel transport/liaison role in 1980, while the main transport mission continued to be fulfilled by the four YS-11M/M-As. Easier maintenance and operational improvements came as a result. B-65 6704 was still with the 61st when decommissioned in October 1983.

A further step-up in performance and comfort came with the arrival of the first of five C90B King Air-based LC-90 turboprop liaison aircraft in 1988, a version of the TC-90s that had already been selected to follow on from the B-65s in the navigation training role.

The 61st’s remit covers the scheduled airlift of JMSDF personnel and materiel to the service’s bases throughout Japan, from Hachinohe in the north and Naha in the south to the triangular atoll that is the Minamitorishima (Marcus Island) military/scientific outpost in the east.

The “milk run” scheduled services then operated by the 61st from Atsugi could be broadly divided into five regular services, serving Okinawa, Iwakuni, the Ogasawara Islands and Kisarazu as well as Hachinohe.
Okinawa: (Mondays) Atsugi → Tokushima → Omura → Kanoya → Naha (retracing those steps on Tuesdays); (Thursdays) Atsugi → Tokushima → Iwakuni → Omura → Kanoya → Naha (returning on reverse route, missing out Tokushima, Fridays)
Iwakuni: (Mondays) Atsugi → Shimofusa → Tokushima → Iwakuni → Atsugi; (every other week) Atsugi → Shimofusa → Tokushima → Ozuki → Iwakuni → Atsugi
Ogasawara Islands: (Tuesdays) Atsugi → (1,240km) Iwo To → (1,280km) Minamitorishima (returning on reverse route Wednesdays) and a weekly service
Kisarazu: Return flights from Atsugi by LC-90 (Wednesdays and Fridays)

The two legs to Minamitorishima being roughly equidistant, at the limit of the YS-11’s range and offering no alternate landing fields, there were cases of flights turning back when the weather changed. Replacement crews would also be night stopped on Minamitorishima. The milestone of having transported 800,000 personnel was passed in August 1995, and in mid-1996 the average number of personnel carried in a year was 37,000 along with 550 tons of freight.

Extensively damaged in a runway overrun accident at Ozuki on September 28, 2009 (as seen here, six days after the incident [link]), one of the YS-11M-As was officially struck off charge the following July.

The already apparent limitations of the JMSDF’s airlift capabilities also greatly inhibited the service’s ability to respond in the aftermath of the Great East Japan Earthquake of March 2011 and at the same time drastically reduced the available airframe flight hours on the three remaining YS-11M/M-As. In mid-October 2011, the decision was taken to acquire not jet aircraft, as had long been surmised (at one stage the use of Kawasaki C-1s had been examined), but six Hercules under a foreign military sales (FMS) contract with the U.S. Navy. These were former U.S. Marine Corps KC-130Rs that would be refurbished and have their refueling equipment removed, prompting the change of designation to C-130R.

The serials of the six C-130Rs, 9051 to 9056, exactly match those assigned to and worn by the UF-2
Albatross amphibians in the 1960s and 70s.

Built in the mid-1970s to a U.S. Air Force contract, all six had been passed to the U.S. Marines and previously seen service from MCAS Futenma in Japan with VMGR-152, at various times and in three cases for extended periods, from the mid-1990s to the latest 2008. Since the mid-2000s, all had gradually been placed in storage at the Aerospace Maintenance and Regeneration Center (AMARC) at Davis-Monthan AB in Arizona.

Undertaken at the Ogden Air Logistics Complex (OO-ALC) at Hill AFB, Utah, on behalf of the U.S. government, the refurbishment programme commenced in February 2013 and involved structural enhancements and corrosion repair as well as the installation of glass cockpits.

The $170 million contract also covered the supply of 30 overhauled T56-A-16 engines. Classroom training courses for JMSDF flight and maintenance personnel were provided by CAE in Tampa, Florida, but the flight training course at Davis-Monthan experienced delays and started in mid-June 2014, three months after the first aircraft’s planned arrival in Japan for testing with the 51st FAS. Training on a second aircraft was conducted at NAS Patuxent River, Maryland, from that August.

The end of 2014 thus saw a major equipment transition, with the arrival of the first C-130R (albeit flown by a U.S. crew) at Atsugi on November 14 and the decommissioning of the YS-11M/M-As on December 24. YouTube footage exists of the YS-11M that visited Fukui Airport in May 2014 [link].

The first major disaster relief operation involving the C-130Rs were the Kumamoto Earthquakes in April 2016.

(Above and below) In the aftermath of the earthquake that struck Hokkaido Prefecture in the early
hours of September 6, 2018, a 61st FAS C-130R was utilized to airlift a Yokohama-based disaster
relief team and vehicle as well as relief supplies to Chitose AB. The signs placed in the lower
cockpit windows read
(left) ‘disaster relief deployment’ and ‘61st Squadron, JMSDF’.

More recently, the longer range of the C-130Rs has led to their involvement in the airlift of personnel assigned to the Deployment Air Force for Counter-Piracy Enforcement (DAPE) missions off the Horn of Africa. For example, the 38th DAPE mission returned from Djibouti on a C-130R and JASDF C-2 in July 2020, landing first at Narita International Airport for tests to prevent the spread of COVID-19 infections before continuing on to their base at Naha (above).

A 61st FAS C-130R departs Minamitorishima, the island that is Japan’s easternmost point,
1,950km from Tokyo. The introduction of the C-130R has made resupplying this far-
flung outpost far easier and more efficient than it ever was in the YS-11 days.

61st FAS Markings

(Photo taken at JGSDF Kisarazu, October 2012)

Reflecting the unit’s line of work and its radio call sign, a tail marking of a camel and the name Caravan had been adopted for the YS-11s by the late 1990s, but this has not been carried over to the C-130Rs. The LC-90s have carried a small version of the camel marking forward of the left-side rear fuselage window, as just discernible in the photo below. The smaller marking was also seen on the noses of the YS-11s (link).

Regular inspect and repair as necessary (IRAN) maintenance checks of the C-130R fleet, which initially involve the removal of external paint, are conveniently carried out at the Atsugi plant of Kawasaki subsidiary NIPPI Corporation. As reported in the June 2020 issue of Kōkū Fan magazine, the first-delivered C-130R (9051) had appeared after such a check in March 2020, dressed not in the usual gloss blue-grey colour scheme—matching that of a conveniently passing P-1 (above)—but sporting a new matt light sky blue scheme instead. Perhaps someone had confused their FS15526 with their FS35526? The aircraft was still a riot of matt light sky blue in February 2021 (link).

Where Were They Then?

Having long been in the habit of procuring new aircraft, the acquisition of used Hercules represented a throwback to the earliest days of JMSDF. This website features Where Are They Now? pages that attempt to track the subsequent fates of SDF aircraft, but this section reverses that process and takes a look back at the long parallel pedigrees of the six C-130Rs with which the 61st FAS is currently equipped.

U.S. Navy F/A-18 Hornets high in the skies over Oregon (above) and a U.S. Marine Corps CH-53E
Super Stallion over the Philippine Sea receive sustenance from KC-130Rs of the often Futenma-
based Marine Aerial Refueler Transport Squadron 152
(VMGR-152). This was the bread-and-
butter work environment of the six Hercules that are now serving in the pure transport role
with the JMSDF as C-130Rs. Also held in storage, the KC-130R in the photo below
(160019) must have narrowly missed out on selection for a second career.

71st FAS

Formed  July 1, 1976 (31st FAW, Iwakuni, US-1)
Current Base  Iwakuni (US-2)

Thanks to the nature of its work and the distinctive types of aircraft it has operated, the 71st FAS is the JMSDF squadron with the highest profile outside Japan.

Having had three US-1s and 83 personnel at the time of its formation, on July 1, 1976, the first full-scale, open-ocean mission by a US-1 took place just a few days later.

On July 12, 1976, an injured crew member was airlifted from the Greek-registered bulk carrier Regal Scout, then around 350 miles off the coast, to Tokyo-Haneda International Airport to receive urgent medical attention. The first Famous Airplanes of the World publication on the US-1, which was published in March 1977, contains details of this epoch-making operation, which can best be summarized in the form of a timeline.

1140 US-1 ready crew gathers in briefing room. The duty officer had received a telephone call giving initial details of the accident on board the Regal Scout (an officer had suffered severe cuts to his left wrist). Bound for Onahama, Fukushima Prefecture, the ship’s location is 350 miles east of Choshi, Chiba Prefecture, in other words a distant 720 miles east of Iwakuni.

As pilot Lt Cdr Nishijima is added as pilot in command and a navigator as rear cabin commander to the 11 members of the ready crew, the specially deployed crew totals 13 members and is to head initially for Atsugi. In overall command of the operation from Iwakuni is Commander Okada, the 71st’s CO.

1200 Engine start on US-1 9071, departure

En route, in the vicinity of Kowa on the Chita Peninsula in Aichi Prefecture at a true air speed of 230kt, a signal is received that orders Nishijima to change course and proceed directly to the vessel’s last known position. A 3rd FAW P-2J (4751) has been rapidly sent to the scene from Atsugi, and a 31st FAS PS-1 (5809) launched to assist in the rescue effort.

The crew makes preparations for a landing and rescue operation on the ocean, but it is clear from the in-flight conversation that they remain a little nervous because this is the first rescue deployment.

1516 Arrival over an adrift Regal Scout. Careful assessments are made of the wind speed and direction, wave heights and lengths, and the direction of swell. Whether the crew of the Regal Scout understands what are likely one-sided radio communications is debatable. Be that as it may, after having decided on a landing point 150 to 200m off the ship’s starboard side, a single low pass is made at a very low altitude to confirm the conditions at sea level.

1535 Landing, after a flight that has lasted 3 hours and 18 minutes. The rescue boat is deployed and, after Nishijima has confirmed that the aircraft’s hull has not received any unexpected damage, heads towards the ship with two on-board rescuers at the helm.

Due to the swell, there had been some concern about whether it would be possible to come alongside and transfer to the ship, but Nishijima manages to board the Regal Scout safely using a long rope ladder deployed from the upper deck.

Approximately 20 minutes later, a group of ship’s crew members gathers starboard amidships near the rope ladder. From among them, Nishijima descends the ladder and transfers to the rescue boat. The patient, who seems to have been rolled up in a blanket on a stretcher with strings at both ends, is lowered over the side and accommodated in the boat, which returns to the aircraft.

Due to the rudimentary first aid carried out on board the ship, drops of blood fall onto the floor of the aircraft’s recovery cabin. After laying the patient on the bed and confirming that the rescue boat has been securely stowed, the crew immediately switches to takeoff preparations.

1618 Safe takeoff from a point in the middle of the Pacific Ocean, destination Haneda. The efforts of the on-board paramedic succeed in staunching the blood.

1710 The paramedic thinks that the patient might still be in a state of shock, so requests that they land as soon as possible. As the US-1 proceeds at full power at an indicated airspeed of 230kt, the feeling is that every second counts.

1800 “Rescue Ivory 71” lands at Haneda after having received permission for a straight-in approach.

Since 9071 was the only US-1 that had not yet had ILS equipment fitted, there had been concerns that the flight crew would have to request a ground-controlled approach for the let-down into Haneda. Having been IMC up to that time, the weather had changed to VMC, and the US-1 had fortunately been able to land unaided.

The flight crew does receive guidance along the complicated airport taxiways, as the US-1 is brought around to the Japan Coast Guard apron, where the patient is transferred to a waiting ambulance.

1810 Mission accomplished, US-1 9071 and its elated crew depart for Atsugi.

Providing round-the-clock cover, the 71st FAS added a rotating detachment of up to two aircraft at Atsugi from March 26, 1982, when a total of seven aircraft were in service. This move served to reduce the response times needed for incidents out in the Pacific Ocean and also over in the Sea of Japan. In 1983, a request to airlift a patient from the Ogasawara Islands for treatment in Tokyo was the 100th emergency airlift mission. The unit’s operations from the Ogawasara (Bonin) Islands, 620 miles (1,000km) to the south of and administered by Tokyo, are limited to the harbour of the main island of Chichijima. (Any patients from the Hahajima group of islands have to be transported to the mainland by JMSDF helicopter via Iwo To. Chichijima and Hahajima have both had night helicopter landing facilities since the early 2000s.)

From the seventh aircraft, which was delivered in March 1982, newly built aircraft were to US-1A standard with uprated engines, and five of the first six were progressively upgraded to -1A standard from September 1981 to January 1986.

Iwakuni, September 2002

The punishment meted out to the US-1A airframes in open ocean operations meant that their service lives would be comparatively short. The first of the replacement US-2s having entered service with the squadron on March 30, 2007, the 71st continued to operate both types, with pilots checked on one type only, until the last US-1A was decommissioned in December 2017.

In the meantime, the 1,000th rescue mission had been successfully completed 38 years almost to the day since the squadron’s formation, on July 8, 2014.

Around 1620 on the previous day, a male sailor on board a fishing vessel located 1,130 km east of Kinkazan, Miyagi Prefecture, had started to complain of severe abdominal pain. Following medical advice that judged urgent medical examination necessary, the ship made a request for assistance to the Japan Coast Guard’s local 2nd Regional HQ. In view of the distance and time factors involved having been passed the request at 2325, the JMSDF initiated a rescue mission, which unfolded in textbook manner as follows:

July 7, 2004/2357 4th Air Wing P-3C takes off from Atsugi
July 8/0026 Captained by instructor pilot Lt Cdr Shōtarō Mori, US-2 9905 takes off, arrives overhead the fishing vessel before dawn
0415 Patient secured on board the US-2, takes off at 0438
0757 P-3C lands back at Atsugi, followed by US-2 at 0814
0832 Patient transferred to waiting ambulance

Having come to the end of their Atsugi detachment, US-2 9905 and its 15-man flight and support crew returned to their Iwakuni home base on July 11, where 500 people attended a ceremony held to mark the passing of the operations milestone. At that time, a total of seven US-1As and US-2s were operational. According to a breakdown supplied to the media by the 31st Fleet Air Wing, those 1,000 rescue missions included 759 involving the airlift of emergency cases from the ocean or remote islands, 165 rescues on the high seas and 13 searches for ships in distress.

(Above and below) Scenes from the events held at Iwakuni on July 11, 2014, to
mark the unit having reached the 1,000th rescue mission milestone three days before.

Kept in a state of readiness at all times, a US-2 is capable of taking to the air within an hour of an accident or other incident at sea, in about 30 minutes if its main engines are in start-ready condition. On average, the 71st conducts around 30 to 40 SAR and disaster relief operations a year.

Episodes in 71st FAS Operations

June 15, 1982 During takeoff and landing training off the coast of Cape Ashizuri, Kochi Prefecture, the left wing float of 9074 broke off upon landing. The aircraft was towed back to Iwakuni by the destroyer Nagatsuki, which happened to be in the vicinity.

Jan. 23, 1992 US-1A 9081’s crew, led by pilot Cmdr. Hideki Kida, rescue a Misawa-based U.S. Air Force F-16 pilot who had ejected 630 nautical miles east of Tokyo after having been struck from below by a KC-135 tanker. Pilot Capt John L. Dolan had been in the water for five hours at the time of his rescue, which was courageously carried out under the most demanding of conditions.

Having risen to the rank of lieutenant general and been placed in command of U.S. Forces Japan and the 5th Air Force in 2015, Dolan made a point of visiting 71st personnel when on a visit to Iwakuni in September that year. Still serving with the unit 23 years later were the flight engineer Warrant Officer Fumio Ootaki, who had then been on his very first rescue mission, and chief petty officers Yukihiro Kamouchi and Noriaki Tazaki.

February 1994  US-1A 9080 used to fly the then Emperor Akihito and Empress Michiko to a ceremony marking 50th anniversary of Battle of Iwo To (Iwo Jima).

January 1995 Airlift of people affected by the Hanshin-Awaji (Kobe) Earthquake and disaster relief supplies

Feb. 21, 1995 Tragedy strikes as only one of the 12 crew members on board US-1A 9080 survives when the aircraft capsizes on landing off Okinoshima, in the Bungo Channel that separates Shikoku from Kyushu.

Having been deployed on rescue missions on 27 occasions in 2012, the 71st Sqn sent a US-2
(shown here) and a US-1A on an SAR training exercise for its traditional first flight of the New Year.
The standard crew complement of both aircraft is at that time 11, comprising two pilots, an SAR
coordinator, two on-board maintenance personnel, three divers, two paramedics and
a sensor operator
(above).

The then CO Shinji Nakahara informed the U.S. Marine Corps reporter (in the background in
above photo) that the aircraft is capable of carrying approximately three tons (6,000 pounds)
of supplies or 30 passengers or 11 flat beds. When the need arises, medical personnel
are also able to conduct conduct surgical operations on board the aircraft.

June 23, 2013 The 71st makes headlines by rescuing TV news anchor Jirō Shinbō and well-known visually impaired sailor Mitsuhiro Iwamoto from a life raft, their yacht having sunk while attempting to cross the Pacific. Weather conditions force the sending of two aircraft to their assistance (link).

Apr. 28, 2015 US-2 9905 involved in a fortunately non-fatal accident when landing on the sea off Cape Ashizuri, Kochi Prefecture. (Aircraft sinks May 1, wreck salvaged.)

Dec. 7, 2016 Following a massive air and sea search, to a US-2 crew falls the sad duty of recovering the body of U.S. Marine Corps pilot Capt Jake Frederick. For reasons that will never be fully known, Capt Frederick had ejected when flying at night as one of a pair of F/A-18 Hornets off the coast of Tosashimizu, Kochi Prefecture.

Destined to be the last to be decommissioned in December 2017, the last-built US-1A

72nd FAS
“Skylark”

Formed  March 26, 2008 (22nd FAW, Omura, UH-60J)
Disbanded Apr. 2, 2018
(Became 224th Flt, remaining under 22nd FAW/FAS)  

Upon its formation under the 22nd FAW at Omura, the 72nd FAS assumed the role of the western Japan-based counterpart of the dedicated search and rescue unit in eastern Japan, the 73rd FAS at Tateyama.

The 72nd operated detachments at Kanoya and Tokushima, but the latter was disbanded on August 31, 2015, and its SAR duties continued from Komatsushima.

(Photos [undated]: JMSDF Omura AB)

Providing emergency patient airlift cover for the remote islands off Kyushu, the 72nd was the SDF’s busiest in terms of the number of deployments. As the incumbent unit of five years’ standing at Omura on May 25, 2013, the 72nd received a certificate from the governor of Nagasaki Prefecture to mark the 4,500th patient airlift mission. (Predecessor units had received certificates marking the 500th mission on June 15, 1977, the 2,00th on September 11, 1996, and the 4,000th on March 17, 2008, a matter of days before the 72nd was established.)

Some idea of the frequency of emergency airlift operations from Omura can be gleaned by taking January 2018 as an example. According to the information released by the 72nd, the squadron was called upon on 15 days that month, on five days twice, for a total of 20 missions. The vast majority, however, involved short return flights of 90 minutes to two hours. That conducted on January 12, 2018, involved airlifting a doctor from Omura to the regional airport at Fukue, also in Nagasaki Prefecture, departing at 1405. A woman who had been taken to Goto Central Hospital had been judged to be in need of urgent transportation to Nagasaki Medical Center in Omura for treatment. Since the prefectural helicopter had at that time been undergoing regular maintenance, the Governor of Nagasaki had placed a request for assistance with the commander of the 22nd Fleet Air Wing. The return flight, which landed back at Omura at around 1650, had involved airlifting the patient and someone accompanying her as well as the doctor.

During the previous calendar year, 2017, Omura-based aircraft had carried out a total of 94 emergency patient airlifts, including 13 in December, those from the Kanoya Detachment only 23, the most being four in July.

For example, on November 19, the Japan Coast Guard had airlifted a sick crewman from a passing ship to a hospital on Amami-Oshima, the largest of Kagoshima Prefecture’s Amami island group. The hospital, however, had discovered that the patient’s condition warranted his transfer to a higher level facility. The prefectural helicopter and Doctor-Heli service being unable to operate at night, the governor had submitted a request for assistance to the JMSDF regional command. This resulted in UH-60J 8975 departing from Kanoya at 0415 for Sadaikuma heliport on Amami-Oshima and flying the patient, a doctor and attendant the 325km to the heliport at the port of Kagoshima, arriving at 0751.

Episodes from its frequent deployments include:

March 2011         Great East Japan Earthquake (also involving both detachments)

July 7, 2011        (Kanoya Det.) Unsuccessful search for 204th Sqn F-15J pilot off Okinawa

March 2012        (Kanoya Det.) Search for crew members missing from fishing vessel off Amami Islands, Kagoshima Prefecture

May 2012            (Kanoya Det.) Search and rescue of yacht crew off Yakushima, Kagoshima Prefecture

May 2012           (Tokushima Det.) Forest firefighting in mountains above town of Naka, Tokushima Prefecture

April 2016          (Omura squadron and Kanoya Det.) Kumamoto Earthquakes

November 2016  (Kanoya Det.) Patient airlift from cruise ship Sky Sea Golden Era

Dec. 7, 2016         Participated in search for F/A-18 pilot (see 71st FAS)

February 2017    (Omura squadron and Kanoya Det.) Search for crew member missing from JMSDF minesweeper Yakushima

February 2017    (Omura) Emergency airlift of angler on visit to Danjo Islands

July 2017            (Omura squadron and Kanoya Det.) Response to torrential rainfall in northern Kyushu

Aside from actual rescues and patient airlift missions, training takes up a major part of any such unit’s operations. In June 2015, proficiency training was conducted utilizing the only hospital with a ground-level helipad in a location at no risk from tsunami in Tokushima Prefecture, that at Houetsu Hospital in the city of Mima. Although the facility had conducted training with other rescue helicopter operators and the JGSDF’s 14th AvSqn, this was the first time that a JMSDF crew flying a heavier class of aircraft had familiarized itself with the approach to, landing at and departure from the hospital.

Naturally, the unit provided demo flights at air shows and other events in the area. A series of photos from the display at the Air Memorial in Kanoya 2014 event can be found here (link). (Clicking on the images produces punchier enlargements).

Bringing the curtain down on independent SAR operations from Tokushima, a ceremony was held on September 1, 2015, to mark the disbandment of the Tokushima Detachment. In attendance were 120 personnel who had served there at various times during the JMSDF’s 55-year SAR presence, dating back to the formation of an SAR unit in 1960. The main ceremonial event being the handing back of the squadron nameplate by detachment CO Junichi Ishii, the recipient in this case was the then CO of the 72nd FAS, Capt Kōichi Oda.

The 2018 reorganization that brought about the demise of the two independent helicopter squadrons, leaving the 71st FAS at Iwakuni as the sole dedicated squadron-level SAR unit, was designed to improve the chain of command, efficiency and thus response times while saving some defence budget yen.

72nd FAS Special Markings

Normally, the 72nd’s aircraft were in the standard colour scheme, with the ‘72’ tail code as their only distinguishing feature. Once in a while, one of its aircraft was given special markings for a particular occasion.

Like its counterpart in western Japan, the 72nd FAS at Omura, the unit’s remit included providing cover for outlying areas, in this case primarily the Tokyo-administered Ogawasawara (Bonin) Islands.

73rd Fleet Air Squadron Demonstration Flight,
Tateyama Base Open Day, October 6, 2013

The October 2013 flying display gave the 73rd FAS an opportunity to demonstrate its firefighting
capabilities for the benefit of the public. Here the pilot keeps his aircraft steady in the hover while
 ground crew members attach a Bambi Bucket used for immediate short-term fire suppression.

The point of release of the Bambi Bucket’s load, which in the case of a UH-60J can be a maximum
of 660 U.S. gallons
(2,500 litres) of water. In an actual operation, the Bambi Bucket will ideally be
replenished by being dunked in a nearby water source, such as a river or reservoir.

Returning for the empty Bambi Bucket to be unhitched prior to landing.

A pair of 73rd FAS UH-60Js come in for landing.

Its exercise over, 8973 is deluged by an automatic taxi-through rinsing system of the type installed at
all JMSDF air bases. This process is essential to prevent corrosion on aircraft that are operated in
salt air environments. Rather than a solid stream of fresh water, a soft spray pattern is used to
remove salt and water-soluble contaminants while avoiding damage to fragile
equipment such as pitot tubes or causing water intrusion.

Also like its sister unit, the 73rd fell victim to the organizational change that came into effect in April 2018, being reduced to SAR flight status (as the 213th Flight) as an integral part of the 21st FAS.

As the following episodes testify, the 73rd’s Iwo To Detachment not surprisingly had to maintain a high state of readiness in the run-up to the reorganization.

Jan. 9, 2018 Works in concert with JASDF UH-60J crew in conducting airlift from Chichijima (in Ogasawara Islands) to Iwo To, from where patient is flown to Atsugi by P-1

Jan. 20, 2018 Patient airlift from Chichijima to Iwo To

Jan. 24, 2018 In accordance with Japan Coast Guard request, airlifts patient from ship lying 260km northwest of Iwo To

Feb. 6, 2018 At the behest of the Tokyo Governor, Iwo To Detachment crew works with JASDF UH-60J crew in conducting airlift of patient from Chichijima to Iwo To

Feb. 14, 2018 A repeat of the February 6 operation

Mar. 10, 2018 At request of Japan Coast Guard, UH-60J sent to airlift ashore sick crew member from ship lying just off coast of Iwo To

Mar. 26, 2018 Twice in one day, the 73rd again called upon to work in concert with JASDF UH-60J crew in conducting an airlift this time from Hahajima in the Ogasawara Islands to Iwo To, from where patient is flown to Atsugi by P-1

In the 10 years of its existence, the 73rd had been deployed 476 times on rescue or disaster relief flights and saved 790 lives.

81st FAS
(VQ-81)

Formed Mar. 30, 1983 (31st FAW, Iwakuni, UP-2J) 
Current Base  Iwakuni (31st FAW, EP-3/OP-3C [811th Flight] and
UP-3D/U-36A [812th Flight])

At the time of its formation as the first JMSDF unit to operate aircraft in the electronic warfare support role, the 81st FAS was equipped with three UP-2Js that had been transferred from the 51st FAS. The fourth and final P-2J converted to the utility standard arrived the following year.

Converted to UP-2J 9161, the former P-2J 4717 had been delivered back to service with the 51st FAS
in 1979. The aircraft is seen here five months into its career with the 81st FAS. Of particular note is
the dayglow BQM-34 Firebee target drone, which sports a tally of 10 parachute recovery markings.

(Photo [Iwakuni, August 1983]: Akira Watanabe)

The role its specially converted aircraft have fulfilled ever since is primarily in support of the anti-aircraft and electronic countermeasures (ECM) training of aircraft and ship crews, be they on individual training missions or on exercise. Each of the three UP-2Js was completed to a different equipment configuration: to carry BQM-34 Firebee unmanned target drones; to create a simulated electronic combat environment for electronic training; and for the gathering of electronic intelligence data.

The P-2J 4719 was chosen for the second UP-2J conversion, 9612. Like 9161, this aircraft was
distinguishable by its solid nose and three under-fuselage fairings.

In the case of UP-2J 9164 (formerly P-2J 4763), however, the nose glazing was retained, as it was
on 9163
(ex-4757 [link]).

The JMSDF’s first jet aircraft came in the form of the U-36A, based on the Gates LearJet Model 36A business jet, the first of which entered squadron service on April 21, 1988, having been delivered after conversion at ShinMaywa’s Tokushima plant in March 1987.

As per the unit’s standard practice, the only squadron marking is the

Designed to work as a team, these aircraft feature a ventral radome housing an HPS-103-(1) weather/search radar. Underwing pylons carry XLQ-2 ECM and AN/ALE-43 chaff dispenser pods or RM-30A towing equipment. Despite leaving a ground clearance of a mere 15 cms, the latter is used in conjunction with the ARS-1P low-altitude, high-speed sleeve target used to hone the skills of the crews on board the close-in weapons system (CWIS)-equipped vessels of the JMSDF. The U-36A’s enlarged starboard wingtip tank incorporates missile seeker simulation equipment in the forward section, that on the port side a low-light camera for use in carrying out, recording and assessing simulated anti-ship missile attacks. 

Tragically, all five crew members lost their lives when U-36A 9203 struck the water off Shikoku during a low-level ECM exercise on February 28, 1991.

In an article about flight safety at Iwakuni posted on its website on August 18, 2017, The Chugoku Shimbun mentioned that a U-36A had overran the runway and fallen into a ditch, injuring its five occupants, that same month.

Initially operated by the 202nd Air Training Squadron from January 1965 and withdrawn from use
when with the 31st FAS on May 29, 1991, B-65 6723 was assigned to the 81st FAS at the time
this photograph was taken at Iwakuni in May 1989. (Photo: Takao Kadokami)

At the end of 1991, an LC-90 was received, and the last B-65 assigned to the 81st (6725) retired the following March. After having been finally decommissioned on June 24, 1992, this aircraft was placed on display at Iwakuni, where it has remained to this day.

An LC-90 was operated by the 81st FAS from late 1991 until the operations of all five of these
aircraft were centralized with the 61st FAS at some stage in the mid-2000s.

The first U-36A again, at the Atsugi open day held in May 2000.

The replacement of the UP-2J fleet was initiated by the delivery of the first of five newly built EP-3s, for electronic intelligence data gathering, on November 22, 1991. The improvement in capability provided by the EP-3 was such that the UP-2Js could be decommissioned on December 13, 1991. 

Delivered in 1991, the first two EP-3s were followed by three more, in September of each of 1995,
1996 and 1999. Missions with these aircraft are normally carried out by 15-man crews.

The delivery of two UP-3Ds optimized for the electronic warfare role followed on March 1, 1999, after a year of flight testing. These primarily provide the jamming duties required during ship air defence training. A third UP-3D, the 107th and last Kawasaki-built Orion, was delivered on February 1, 2000, but the UP-3Ds and U-36As were transferred to the 91st FAS (see below) upon its formation in March 2001.

The 81st was assigned the first of its ultimately five OP-3Cs on March 15, 2002. First flown on September 19, 2000, this first conversion from a standard JMSDF P-3C had been delivered for testing on March 1, 2001. Serving in the image-gathering role, for which their equipment fit includes global positioning systems, sideways-looking airborne radar (SLAR) and long-range oblique photography (LOROP) camera systems, the OP-3C aircraft enable the editing of intelligence on board and the relaying of that intelligence via satellite communications to land- or ship-based locations..

(Above) An early photo of the first OP-3C, the former P-3C 5043. The first and second aircraft were
initially equipped with SLAR and LOROP sensors, respectively. The more recent photo below
shows the second aircraft sporting the now standard low-viz colour scheme and carrying a
LOROP sensor pod. These aircraft normally carry a crew of 10.

81st Fleet Air Squadron Orions, Iwakuni, September 16, 2012

The second OP-3C, 9132 had started life as the standard P-3C 5069.

A close-up of the front fuselage of OP-3C 9132. The trend in recent years has been to not display the
JMSDF’s special mission Orions so prominently at public events.

Displaying its protuberances to good effect, EP-3 9172 comes to the end of its landing run.
2021 will mark the 30th anniversary of the delivery of the first two of this type.

The 81st was the surviving entity following its merger with the 91st FAS on October 1, 2020, the all-Orion 811th Flight being joined by the return after 19 years, of the UP-3Ds and U-36As that now make up its 812th Flight.

Taking its aircraft from the 81st FAS, the 91st was equipped with three UP-3Ds and five U-36As upon its formation. An LC-90 operated by the 91st was reassigned to the 61st FAS in March 2005.

(Above) The second of its type delivered, on March 9, 1999, 91st FAS UP-3D 9162 shows off the
fairings on its undersides. Having flown for the first time on November 7, 1997, its predecessor
(below) had been delivered a year earlier, on March 5, 1998.

The above photo shows the first UP-3D equipped with RM-30A reeling machine launchers for the
target-towing role on its outboard underwing stations. At the Iwakuni open day in September 2012
(below), a ground crew gave a performance of the carefully choreographed procedures designed
to ensure that the RM-30A was safely and securely mounted on its pylon.

The two-tone scheme of white and grey the UP-3Ds had worn since their introduction eventaully
gave way to a low-visibility scheme. These aircraft normally carry a crew of eight.

A dark day in the annals of the 91st FAS occurred on May 21, 2003, all four crew members—pilots Lt (jg) Masanori Hasegawa (aged 27) and Ensign Katsuichi Miura (25), who were accompanied by Chief Petty Officer Gen Kawabe (52) and Petty Officer Third Class Takuto Honda (20)—losing their lives when their U-36A crashed on takeoff from Iwakuni. The accident happened when they and a US-1A crew were conducting ‘touch and go’ training, and the cause was identified as insufficient separation between the U-36A and the wake turbulence from the US-1A, which had taken off 28 seconds before them. 

The fifth of the six U-36As received by the JMSDF was on static display (and 9204 and 9206
present in a hangar)
at Iwakuni in September 2012, during their time with the 91st FAS.

The disbandment of the 91st FAS, on October 1, 2020, sent the three UP-3Ds and four U-36As back from whence they had come to form the 81st FAS’s 812th Flight.
