So far, the only nation to build the F-15 Eagle under license is Japan. In June-July of 1975, Japanese officers carried out two flight evaluations of the F-15A/B Eagle at Edwards AFB. In December of 1977, the Japanese National Defense Council announced that the Eagle had been selected to supplement and eventually replace the Lockheed F-104J Starfighters serving with the Nihon Koku Jietai (Japanese Air Self Defense Force, or JASDF). The Japanese Eagle was to be designated F-15J, with the two-seat version being F-15DJ. They were to be the Japanese counterparts of the F-15A and B respectively.
A license was acquired for manufacture of the F-15 in Japan, with Mitsubishi being selected as the prime contractor. Initial plans were for the first two single seaters and 12 two-seaters to be built in St Louis by McDonnell under Project Peace Eagle. The remainder would be manufactured in Japan by Mitsubishi at its plant in Komaki. A similar sort of arrangement had been worked out for license manufacture in Japan of the Eagle's predecessor, the F-4 Phantom.
As it turned out, the Japanese F-15s were quite similar to the early production blocks of the USAF F-15C and D. However, Japanese Eagles were to differ from the Air Force Eagles primarily in omitting certain sensitive items of electronic countermeasures equipment, such as the ICS and EWWS sets. In their place, provisions were made for the installation of a Japanese-built radar warning system. Among the indigenous equipment fitted to the JASDF F-15J and F-15DJ aircraft is the J/APR-4 RWR, the J/ALQ-8 ECM suite, the AN/ALE-45 chaff/flare dispenser, and the XJ/APQ-1 radar warning system. Nuclear delivery equipment was omitted, data links were installed and MER-200P bomb racks were provided.
The first two F-15Js were built by McDonnell (USAF serials 79-0280/0281, JASDF serials 02-8801/8802. 02-8801 flew for the first time on June 4, 1980. The next eight (JASDF serials 12-8803, 22-8804/22-8810) were assembled by Mitsubishi from McDonnell-built knock-down kits. The first Japanese-assembled F-15J (12-8803) flew at the Mitsubishi plant at Komaki on August 26, 1981.
Twelve of the two seat F-15DJs were built by McDonnell Douglas, with the remainder (from FY 1988 onward) being built by Mitsubishi.
The service evaluation was carried out by the Koku Jikkendan (Air Proving Wing) at Gifu AB on Honshu, the first planes being delivered in March of 1981. The first front-line JASDF Eagle squadron was 202 Hikotai (Squadron) of 5 Kokudan (Air Wing), based at Nyutabaru on the southern Japanese island of Kyushu. It received its first Eagles in 1981-82, replacing the units F-104J Starfighters. 202 Hikotai acted as the OCU for the remainder of the squadrons that were to receive the Eagle. In 1986/87, Eagles began to replace the F-4EJ in JASDF service, the first unit to convert being 303 Hikotai at Komatsu.
The following JASDF units have received the F-15J and F-15DJ:
-
201 Hikotai of 2 Kokudan based at Chitose
received Eagle in 1986, replacing F-104J
-
202 Hikotai of 5 Kokudan based at Nyutabaru
received Eagle in 1981, replacing F-104J Acts as OCU. Scheduled for disbanding in summer of 2000, to be replaced by 23 Hikotai which will be newly formed at Nyutabaru AB.
-
203 Hikotai of 2 Kokudan based at Chitose
received Eagle in 1983, replacing F-104J
-
204 Hikotai of Kokudan based at Hyakuri
received Eagle in 1984, replacing F-104J
-
303 Hikotai of 6 Kokudan based at Komatsu
received Eagle in 1986/87, replacing F-4EJ
-
304 Hikotai of 8 Kokudan based at Tsuiki
received Eagle in 1990, replacing F-4EJ
-
305 Hikotai of 7 Kokudan based at Hyakuri
received Eagle in 1993, replacing F-4EJ
In addition, 6 F-15DJs were assigned to the Hiko Kyodotai, an aggressor squadron based at Nyutabaru. Problems with the Mitsubishi T-2's low power and excessively-high accident rate led to a decision to adopt the F-15DJ for the agressor squadron.
JASDF Eagles were initially powered by a pair of Pratt & Whitney F100-PW-100 turbofans. From 1991, these have gradually been replaced by F100-PW-220s, which are more reliable but slightly lower-rated.
Currently, orders for 220 F-15s have been issued (180 single-seaters and 40 two-seaters), out of which 187 (150 F-15Js and 37 F-15DJs) have been delivered. Eight JASDF Eagles have been lost in accidents.
In 1997, the JASDF began a program to upgrade its F-15J fleet. This included a radar and central computer upgrade to bring JASDF F-15s up to the standards of MSIP-II USAF F-15s. Also included is an uppgrade of the J/ALW-8, plus new FLIR and IRST systems. It is hoped that the upgraded F-15Js will have the ability to carry and launch "fire and forget" BVR AAMs.
The last F-15 for the JASDF was delivered by Mitsubishi Heavy Industries on December 10, 1999. This aircraft was a F-15DEJ two -seater. In total, the JASDF received 213 F-15s, with 163 F-15Js and 36 F-15DJs having been built by Mitsubishi and two F-15Js and 14 F-15DJs being built by McDonnell Douglas.
The JASDF has a complicated six-digit serial system. The first digit corresponds to the last digit in the procurement year (0 = 1980, 1 = 1981, etc), the second the basic class of aircraft (2 = multi-engined), the third the basic role (8 = all-weather fighter), and the last three digits the individual aircraft number in sequence.
