The McDonnell Douglas - Mitsubishi F-15J/DJ Eagle is a twin-engine, all-weather air superiority fighter based on the McDonnell Douglas F-15 Eagle in use by the Japan Air Self-Defense Force (JASDF). The F-15J was produced under license by Mitsubishi Heavy Industries along with McDonnell Douglas. The subsequent F-15DJ and F-15J J-MSIP (MSIP Configuration II Aircraft) variants were also produced. Japan is the largest customer of the F-15 Eagle outside the United States. In addition to combat, F-15DJ roles include training. The F-15J Kai is a modernized version of the F-15J. Kai was an early designation that has gradually subdivided; nowadays, Japan no longer uses 'kai' to refer to newly upgraded F-15Js. Instead, Japanese predominantly use J-MSIP or F-15MJ.

F-15J/DJs are identical to F-15C/Ds aside from the ECM, radar warning system, and nuclear equipment. The AN/ALQ-135 Internal Countermeasures System is replaced by the indigenous J/ALQ-8 and the AN/ALR-56 Radar warning receiver is replaced by the J/APR-4. The engine is the Pratt & Whitney F100 turbofan, produced under license by IHI Corporation. Some aircraft still have an inertial measurement unit, an old type of the inertial navigation system. All F-15J/DJs have two UHF radios, which are also VHF capable.

The F-15J is characterized by an indigenous data link, but they do not support Link 16 FDL mounted by USAF F-15Cs. 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.

Mitsubishi received the F-15C/D Multistage Improvement Program (MSIP) and in 1987 began upgrading the F-15J/DJs. Improvements included an uprated central computer, engines, armament control set and added the J/APQ-1 countermeasures set. The F100-PW-220 (IHI-220) was upgraded to the F100-PW-220E (IHI-220E) with a digital engine electronic control retrofit. Differences in appearance from earlier F-15Js include the J/ALQ-8 ICS with an ICS antenna mounted under the intake. The J/APQ-4 RWR antenna position on the F-15J/DJs is the same as F-15C/Ds, but the lens of F-15J/DJ MSIPs is black rather than white for F-15C/Ds.

Historical Account: "Operation Atlantic Eagles" - Japan completed its first-ever fighter jet deployment to Canada and Europe on Wednesday in an unprecedented display of support for NATO partner countries as well as a demonstration of the Air Self-Defense Force's long-distance operational capabilities amid growing concerns over the international security situation.

Named "Atlantic Eagles," the mission involved four F-15Js from Chitose Air Base, accompanied by two refueling and two transport aircraft from various bases across Japan. The contingent, which also included 180 personnel, first landed at the U.S. Eielson Air Force Base in Alaska. From there, they proceeded to Canadian Forces Base Goose Bay in Canada, RAF Coningsby and RAF Brize Norton in England, and Laage Air Base in Germany.

The ASDF said the September 14th to October 1st deployment was meant to deepen cooperation and exchanges with fighter squadrons from partner countries in North America and Europe. But experts such as Sebastian Maslow, an associate professor at the University of Tokyo, go further, arguing that the move also highlights the growing momentum of Japan's security cooperation with NATO partners as Tokyo appears increasingly willing to take on a more proactive role in international security affairs.

Atlantic Eagles comes as several NATO member states have increased their own deployments of military assets to Asia, including Japan, particularly after Russia's invasion of Ukraine in February 2022.

Defense Minister Gen Nakatani highlighted this when talking to reporters ahead of the mission. "In recent years, European countries such as Canada, the United Kingdom, and Germany have been steadily strengthening their engagement in the Indo-Pacific region, regularly dispatching fighter jets and naval vessels to areas surrounding Japan," he said on Sept. 12th.
