Air Development & Test Wing


Air Development & Test Wing

Formed  As Air Proving Group:
Dec. 1, 1955 (T-34A at Hamamatsu)

 As Air Proving Wing: April 11, 1974

 As Air Development & Test Wing: March 1989 

Current Base Gifu (Air Development & Test Command, various aircraft) 

Starting out in November 1955 as an operational test and evaluation unit offshoot of a research unit within the 1st Flying Training School at Hamamatsu, the Air Proving Group boasted 28 personnel and two T-34As at the time of its formation the following month. From assembly to delivery, the Group handled the Vampire that was its first jet, imported to assess the advantages and disadvantages of its side-by-side seating configuration, and had graduated to the utilization of F-86Fs by the following year. Examples of the T-6G and T-33A as well as a solitary T-28 were supplied, but as space was being taken up by the fighter units that were then in the process of forming, a move was made and the unit’s long residency at Gifu commenced on March 25, 1957.

During the period of F-86F operations, the aircraft assigned to the APG were regularly changed. The flight test programmes conducted on the type included the Japanese-designed XAAM-1 air-to-air missile and tactical air navigation (TACAN) equipment. Whereas the F-86F was to remain in APG service until late in 1971, a small number of F-86Ds were only operated for a short time. 

From January 1958, the APG took charge of the first flight of the T1F2 trainer (later the Fuji T-1), Japan’s first indigenously produced postwar jet aircraft, and then went on to conduct the test flight and acceptance testing programmes. Flight testing of an F-104J Starfighter commenced in 1962, but as Gifu possessed no expertise in the operation of the type, a detachment was sent to Chitose air base until 1966 to conduct all types of testing from there. Attended by four trainees, the first test pilot course (TPC) was commenced in 1969.

Having been renamed as the Air Proving Wing on April 11, 1974, to reflect its higher status, a succession of JASDF types—among them the F-4EJ, T-2 and C-1—continued to undergo initial and ongoing testing during the course of the 70s. Over the years, some types have undergone extended test programmes, others (such as the C-130H, U-4 and U-125) only brief periods of operational testing prior to service entry.

1956 de Havilland Vampire T.55 63-5571

JASDF Vampire T.55

Built at de Havilland’s Broughton factory in January 1956, this was the Vampire imported into Japan for evaluation in August of that year. Already withdrawn from active operations in January 1960, the aircraft was used for PR/recruitment purposes at SDF exhibitions, which included being parked next to a roller coaster at an event held at Tokyo’s Futako-Tamagawa Park in March 1963 (link), then passed to the 1st Technical School at Hamamatsu as an instructional airframe. It was then stored and occasionally given a public airing at Hamamatsu from the 1970s before being placed on permanent display at the JASDF Air Park at that base in March 2000.

1958 Fuji T1F2 (T-1A) 85-5801

ADTW T-1A(Photo [exact date unknown]: JASDF Gifu AB)

The first new aircraft to be put through a test programme at Gifu was the T1F2 (later T-1A), which manufacturer Fuji had flown for the first time from its Utsunomiya facility on January 19, 1958.


1963 Lockheed F-104J Starfighter 36-8536

ADTW F-104J(Photo [exact date unknown]: JASDF Gifu AB)

Delivered in August 1963, F-104J ’536 spent its entire career with the then Air Proving Group/Wing. Following its withdrawal from use in April 1986, the airframe was acquired at some stage by the Kissa Hikōjō (Airfield Café) in Hamamatsu, Shizuoka Prefecture, which opened in December 1987. The aircraft’s nose section was still present in December 2016.


1971 McDonnell-Douglas F-4EJ Phantom II 17-8301

ADTW F-4EJ 301(Photo [exact date unknown]: JASDF Gifu AB)

Another aircraft that has enjoyed permanent residency at Gifu, the first F-4EJ was one of the pair that arrived in Japan from the McDonnell-Douglas factory in St. Louis, Missouri, in March 1971. (See 2016)

1971 Mitsubishi XT-2 19-5101

ADTW XT-2 (Photo [date unknown]: JASDF Gifu AB)

First flown on July 20, 1971, the first prototype XT-2 was delivered to the then APG in December that same year. Having officially lost the ‘X’ in its designation on August 29, 1973, this T-2 went on to serve another 30 years before being retired early in 2003. On April 14, 2003, a ceremony was held to mark its addition to the aircraft on display at Mitsubishi Heavy Industries Nagoya Aerospace Systems’ Komaki South Plant, where the exhibits from the adjoining museum were being relocated to within MHI’s Oe Plant during the course of 2018.

1972 Kawasaki C-1 28-1001 (originally 18-1001)

ADTW XC-1(Photo [date unknown]: JASDF Gifu AB)

Having been flown for the first time on November 12, 1970, the XC-1 joined the Gifu test fleet in 1972. (See 2016)

1978 Fuji T-1B 05-5810

T-1B 810 APW(Photo [Misawa, Oct. 1978]: Akira Watanabe)

Delivered to the APG on November 30, 1960, the 10th T-1 built had been modified from T-1A to T-1B standard during manufacture. Seen in the natural metal finish that was standard at the time, this aircraft spanned the three iterations of the JASDF’s test establishment. Its last flight took place on March 2, 2006. (See AD&TW Special Markings/2005)

1978 Fuji T-3 81-5501

JASDF ADTW T-3(Photo [date unknown]: JASDF Gifu AB)

Today stored at Shizuhama for display purposes, the first T-3 (Fuji KM-2B) made its maiden flight on January 17, 1978, and was passed to the APW later that year.


1980 McDonnell-Douglas F-15J Eagle 02-8801

JASDF ADTW F-15J 801(Photo [date unknown]: JASDF Gifu AB)

As the service second only to the U.S. Air Force in terms of the number of F-15s procured, the JASDF has conducted ongoing upgrade and weapons integration testing since the first pair arrived from manufacturer McDonnell-Douglas in 1980. Shown here, the first aircraft had completed its maiden flight on June 4 of that year. (See 2016)

1982 Mitsubishi T-2CCV 29-5103

ADTW T-2CCV(Photo [date unknown]: JASDF Gifu AB)

Originally delivered in July 1972, the third prototype XT-2 (29-5103) was passed to the APW in April 1982 for conversion to T-2CCV (Control Configured Vehicle) standard. The fly-by-wire technology flight test programme lasted two years. Finally withdrawn from use on October 31, 2002, the aircraft was placed on loan display at Gifu-Kakamigahara Air and Space Museum in December 2014. (See dedicated page on Gifu-Kakamigahara Air and Space Museum)

1985 F-104J Starfighter 36-8549

ADTW F-104J 36-8549(Photo: Akira Watanabe)

Komatsu, May 19, 1985. This F-104J was delivered to the JASDF in October 1963 and was nearing the end of its service carrer when this photo was taken. Still wearing APW markings, the aircraft’s last home was a narrow enclosure in Sun Green Park in what is now the city of Fukaya, Saitama Prefecture, from where it had been removed from display by 2005.

1985 Kawasaki EC-1 78-1021

EC-1 Hunini(Photo: Hunini via Wikimedia Commons)

Seen here on a return visit to Gifu in November 2008, the Kawasaki EC-1 was only temporarily assigned to the APW during its initial development. First flown on December 3, 1984, the aircraft was based at Gifu from late 1985 to June 1986, when passed to the then Electronic Warfare Support Squadron. 

1986 T-2 29-5102

APW T-2(Photo: Akira Watanabe)

Returning to its birthplace, the second T-2 is seen here at Komaki in November 1986. Originally delivered to the 4th Air Wing in Matsushima in March 1972, this aircraft also ended its service career with the APW and was placed—in natural metal finish save for blue APW tail markings—at a Gifu base monument, dedicated on December 1, 2005, to commemorate the 50th anniversary of the AD&TW.

1986 Lockheed T-33A 61-5213

T-33A APW 1986(Photo [Komaki, Nov. 1986]: Akira Watanabe)

The test unit at Gifu operated a number of T-33As. This Kawasaki-built example was delivered to the JASDF in September 1956 and with the APW from at least 1983 up until its withdrawal from service at the end of January 1994.

1986 Boeing-Vertol CH-47J Chinook 66-4471

APW CH-47J(Photo [date unknown]: JASDF Gifu AB)

The first JASDF CH-47J was a pattern aircraft built by Kawasaki from a Boeing-supplied kit in 1986; the aircraft was eventually withdrawn from transport squadron use in October 2001.

A closer view of one of the aircraft in the formation photo above, the second T-4 built is seen here at Misawa in May 1989, the year that the Air Proving Wing was renamed the Air Development & Test Wing.


1991 Sikorsky UH-60J 18-4551 and ’552

JASDF ADTW UH-60J(Photo [date unknown]: JASDF Gifu AB)

The first JASDF UH-60J was handed over at Komaki on February 28, 1991, after which the first two aircraft underwent testing with the AD&TW.

1992  British Aerospace U-125 29-3041

JASDF ADTW U-125(Photo [date unknown]: JASDF Gifu AB)

Delivered in December 1992, the first of the three U-125s acquired for navaid calibration was also initially assigned to the AD&TW. The other two aircraft followed in 1994 and 1995, after Raytheon’s acquisition of British Aerospace’s Business Jet Division in 1993.

1994 Beechcraft T-400 41-5052

JASDF ADTW T-400(Photo [date unknown]: JASDF Gifu AB)

The photo shows the second T-400 in the markings of the AD&TW. A total of 13 aircraft of this type were delivered over the 10-year period up to 2004. 

1994 C-1 28-1002

C-1 Schleiffert(Photo [Nov. 1994]: Rob Scheiffert)

The second prorotype C-1 spent a mere 40 years at Gifu following its delivery in 1972. Released to squadron service early in 2012, the aircraft was still active with the sole operator, the 401st Airlift Squadron at Iruma, late in 2018. 

1994 T-2 69-5133

T-2 Schleiffert(Photo [Nov. 1994]: Rob Schleiffert)

Formally handed over to the JASDF on November 1976, this T-2’s time at the AD&TW including its use as a chase plane during Mitsubishi F-2 crosswind landing trials.

1994 T-33A 71-5275

ADTW T-33A Schleiffert (Photo: [Nov. 1994]: Rob Schleiffert)

Originally delivered to the JASDF in June 1957, this Kawasaki-built example was based at Gifu in the 1980s and 90s. Placed in store after ending its service career at Chitose in May 1997, ’275 was finally broken up and disposed of in 2014.

1995 Raytheon (British Aerospace) U-125A 52-3001

2000 FST-2Kai 59-5107

2000 FST-2Kai 59-5107

The seventh (pre-production) T-2 was the second of the two ground-support adaptations built. After testing carried out by Mitsubishi from Komaki, the aircraft was ferried to the APW in late August 1975. Retaining the trainer’s rear cockpit and canopy, the only external difference was the passive warning radar antenna housing atop the tailfin. Seen here at Gifu in October 2000, this aircraft was placed on display at Gifu in February 2017.

2002 Fuji T-7 26-5901 and ’902

JASDF ADTW T-7(Photo [date unknown]: JASDF Gifu AB)

Then known as the T-3Kai, the first T-7 made its maiden flight on July 9, 2002. The first two aircraft were used for pre-service testing, and other examples of the total of 49 delivered up until September 2008 have occasionally been taken on strength at Gifu. These two aircraft were in line service with the 12th Flying Training Wing at Hofu AB in 2018.

2008 Boeing KC-767 87-3602

Initially assigned to squadron service, this F-15J had taken up a residency at the AD&TW by 2008 and, aside from return visits to Komaki for maintenance, has remained in service there to this day. The aircraft’s involvement in the F-15J modernization programme is evidenced by the infrared search and track (IRST) system housing on top of the nose.

The second prototype C-2 stands in front of Hangar No. 7 at a rain-swept Gifu in October 2012. Having flown for the first time on January 27, 2011, this aircraft was heavily modified for the electronic intelligence (ELINT) role, in which guise it first flew from Gifu on February 8, 2018. As shown here in August 2018 (link), some of the flight test programme is being conducted from Iruma, which will be its eventual home.

Like other Gifu-assigned Phantoms, ’301 was never upgraded to F-4EJ
Kai standard.

F-15J 02-8801 Gifu HuniniA mere 36 years after its arrival from McDonnell-Douglas in 1980, the first F-15J was
also present on the Gifu flight line.

JASDF TACOM UAV(1001)(Above and below) The Gifu AB open house events provide an opportunity to see other hardware that is
or has been undergoing testing. The F-15J above has a sharkmouth-adorned TACOM UAV on its
starboard inboard pylon beneath a Type 90 air-to-air missile (AAM-3). Seen sharing a pylon
with Type 04 (AAM-5) short-range missiles, the UAV below sports a digital pixelated 
camouflage scheme; note the SUBARU Corporation logo on the engine intake blank.
(This UAV is now on display next to the F-1 and F-104J at the AD&TW’s Fuchu HQ.)

X-2 (51-0001) Gifu Hunini(Photo [Nov. 2017]: Hunini via Wikimedia Commons)

A Ministry of Defense project, the X-2 landed at Gifu at the end of its first flight from Komaki, on April 22, 2016, and has been stored there since the end of its series of data-gathering flights, which were carried out with an AD&TW T-4 chase plane in attendance. The pitot tube that was mounted on the nose for its flight test programme has been removed. (This aircraft was on display again in November 2018.)

APG / APW / AD&TW Tail Markings
As worn by Air Development & Test Wing aircraft to this day, the marking of what was then the Air Proving Group first appeared in July 1964, having been created by a member of the maintenance team. The design comprised a black, arrowhead-shaped sonic boom shock wave and an orbiting artificial satellite, which were very evocative symbols of the scientific age in the late 50s and 60s. Examples of the F-86F, F-104J and T-1 (undated link) also carried the abbreviation ‘APG’, and in its day ‘APW’, but with the exception of special markings this practice ceased with the advent of the AD&TW.

On occasion in the past, aircraft carried the initials ‘TRDI’ on their tails, to indicate testing being conducted at the behest of the Technical Research and Development Institute arm of the Japan Defense Agency (since 2015 the Acquisition, Technology and Logistics Agency of the Japan Ministry of Defense.)

The 10th T-1 built in the special markings applied for the AD&TW’s 50th anniversary in 2005. Retired on March 2 the following year—the same day as the AD&TW’s T-2 59-5107 flew for the last time—this aircraft has been on display loan to the nearby Gifu-Kakamigahara Air and Space Museum since January 2007.

November 2017 Gifu City 450th Anniversary  T-4 66-5602

T-4 (66-5602) Gifu Hunini

Three of the four T-4s that made up the four-aircraft formation photographed in 1986 were present at the Gifu open house event in November 2017. One featured a tail marking (below) featuring the logo for プロジェクト(Project) GIFU CITY, a tourism promotion campaign commemorating the city of Gifu’s 450th anniversary. In 1567, the famous local warlord Nobunaga Oda (1534–1582) changed the name of Inoguchi to Gifu*, elevating the village to town status in the process. The 信長公 means Lord Nobunaga, and the ‘0’ in よんごーまる (‘450’) contains the cross section of a gourd that formed a mon (crest) of the Oda clan. (Photos: Hunini via Wikimedia Commons)

* As an historical aside, the “gi” in Gifu was taken from Qishan, the mountain in China where Wen Wang (1112–1050 BC) set out to establish the Zhou Dynasty, laying the foundations for 800 years of peace. The “fu” refers to Qufu, the birthplace of the revered Chinese philosopher Confucius (551–479 BC). The name now shared by a city and prefecture thus stems from Oda’s desire to make his region a peaceful place of learning, which the AD&TW at least in part maintains.

At the Gifu base event in November 2018, at least three aircraft were decorated with blue “eyes” on their noses. These are a reference to an anime television series called Dragon Pilot: Hisone and Masotan, which is set at Gifu AB. One of the aircraft, on static display in a hangar, had its real serial (12-8928) changed to that of an aircraft in the anime, ’02-8999’.
