The Mitsubishi F-15J/DJ Eagle is a twin-engine, all-weather interceptor fighter based on the McDonnell Douglas F-15 Eagle by use the Japan Air Self-Defense Force (JASDF). It was produced under license in Mitsubishi Heavy Industries, and the F-15DJ and the F-15J Kai were also produced. The Japan is largest customer of the F-15 Eagle outside the United States.[1]

F-15Js has the roles of the combat including few ground attacks, and, as for F-15DJs, there are a combat and training, and F-15J Kais are the version that F-15Js modernized.

Development

For the fighter which became the succession of F-104J/DJ Starfighter and F-4EJ Phantom II, the Japan Defense Agency (JDA; now Ministry of Defense) examined an McDonnell Douglas (now Boeing) F-15C/D Eagle in 1975. The companies including Mitsubishi Heavy Industries were led to the Japanese Government in April, 1978 and got a license of F-15C/D.[2]

The Department of Defense (DoD) took criticism in an American Diet and did not show Electronic Warfare system and Engine when admitted licensed production to Japan. They were exported to Japan since it was produced till it was completed in United States. This licensed production did not bring Japanese industry an effect of the development, but contributed though kept the base which was necessary for production for fighters. It achieved the purpose of own fighter which Japan liked.[3]

Japan Air Self-Defense Force acquired 203 F-15Js and 20 F-15DJs, of which 2 F-15Js and 12 F-15DJs were built in St. Louis of McDonnell Douglas.[2] It was named Pease Eagle program by FMS, and the first F-15J built in St. Louis was delivered to United States Air Force, and it did first flight on June 4, 1980, and it was cruised on July 15 to Japan. Additionally, 8 F-15Js were manufactured in large componets and shipped to Japan for final assembling by Komaki of Mitsubishi, and the first of these making its maiden flight on August 26, 1981 (#12-8803).[4] Companies divided the remainder share and produced it under license from 1981, and it was produced by final assembling in Mitsubishi.[2]

The Japanese government requested it through U.S.-Japan Forum (S&TF) in 1980 to access advanced technology, but failed in it. The JDA and the DoD held an annual meeting about relaxation of the regulation after a program was started. In these meetings, the DoD official gave back the answer that was good for access to the technology of the composite material.[5]

The first F-15J/DJ were sent to the 202 Squadron in the latter period of 1981, and it was reorganized to the 23 Flying Trainig Squadron as an Eagle FTU in Nyutabaru base on December 21, 1982. The JASDF brought a plan to form the first squadron forward by notorious KAL007 shooting down with Soviet Su-15 on September 1, 1983. And, in Chitose base where the 203 Squadrons crossed La Pérouse Strait from Soviet Fighter base on Sakhalin Island, as for F-15Js, a F-104J and a shift began in March, 1984.[2][6]

Design

An ECM antenna position of Mitsubishi F-15J MSIP.

F-15J/DJs is identical to F-15C/Ds from ECM, radar warning system, and nuclear equipment. The AN/ALQ-135 Internal Countermeasures System is replaced by indigenous J/ALQ-8 and the AN/ALR-56 Radar Warning Receiver is replaced by J/APR-4. The engine is the Pratt & Whitney F100 turboshaft, which IHI Corporation produced under license. Some are still characterized by Inertial Measurement unit, an old type of the Inertial Navigation unit. All F-15J/DJs has two old UHF radios, which are also VHF capable.[7]

JASDF pilots does not use much Japanese, but is characterized by a indigenous Tactical Electronic Warfare System suite because the non-Japanese is effective. F-15Js is characterized by indigenous data link, but they do not support Link 16 FDL mounted by UASF F-15C. It works as a basic bidirectional link with the Japanese ground-controlled intercept network, and it is limited because it is not a true network.[7]

Mitsubishi received F-15C/Ds MSIP and began with 1987 on F-15J/DJs to produce. Improvements included an uprated central computer, engines, Armament control set and added J/APQ-1 countermeasure set. Even the JASDF F-15s which already went into service caught the Japanese MSIP at the time of repair (IRAN).[4][8][9] F-15J MSIPs were replaced from 1992 to F100-PW-220 (Also IHI-220 as); from 1996 to F100-PW-220E (Also IHI-220E as) was replaced.[10] The difference in the appearance includes J/ALQ-8 ICS which an ICS antenna mounted under the intake. The J/APQ-4 RWR antenna position of F-15J/DJs is the same as F-15C/Ds, but the lens of F-15J/DJ MSIPs are black for white F-15C/Ds.[7]

Improvement in MTDP

F-15J MTDP, it received 2nd phases modernization, and can see a change around the intake.

F-15Js have been equipped with the Japanese-built AAM-3 missile, an improved Sidewinder follow-on with distinctive "barbed" forward fins. Japan has been trying to obtain an Advanced fighter (F-22 Raptor in days) to replace the F-15, but the search has been troublesome, and so the F-15J fleet is now being generally upgraded to keep the aircraft in fighting trim.[11] In July 28, 2003, examination F-15J of the modernization did first flight (#928), and it was delivered to the JASDF Air Development Test Wing on October 21, 2003.[12][13]

In December 10, 2004, the Japanese Government approved a Mid-Term Defense Program (MTDP) to perform modernization of F-15J MSIPs in five years by the cause of a new National Defense Program Guidelines.[14] It appears the upgrade is being implemented in phases, but ultimately the refits will include a new ejection seat; replaced IHI-220E engines; more powerful processor; uprated electrical generation and cooling capabilities to support more avionics and the Raytheon AN/APG-63(V)1 AESA radar.[11] The APG-63(V)1 radar has been retrofitted to F-15Js by Mitsubishi Electric produced them under license from 1997. The Raytheon expects the programme will ultimately installing to 80 F-15Js.[15]

The Ministry of Defense (MoD) requested modernization and the reconnaissance deployment of F-15Js in June 2007, and it was a plan to improve certain F-15Js with synthetic aperture radar pods; these aircraft will replace RF-4 Phantom II currently in service.[16][17]

In December 17, 2009, On the approved budget, the upgrade F-15J with Reconnaissance capacity plan disappeared after the Democratic Party arrived at the government by General Election in 2009, and they were shelved the acquisition of the new Reconnaissance aircraft and the new Cargo aircraft in the revised MTDP, and gave priority to improvement of the F-15J and the F-2. F-15Js was increased from 26 to 48, and MoD purchased the part of the modernization for 38 fighters, however, the budget for improvement for the modernization is unfinished. 48 F-15Js of those get a Link 16 datalink and helmet-mounted sight after getting an original MTDPs modernization.[18] The new radar will support the AAM-4 missile, the Japanese answer to the AMRAAM, and the helmet-mounted sight will support the AAM-5 dogfighting missile, which will replace the AAM-3.[11]

As for the new MTDP approved on December 17 of the next year, the modernization retrogressed to 16 F-15Js.[19] The MoD reduced it and they submitted 10 F-15Js modernization plan and restrained it.[20]
