Development and Introduction of the F-15J/DJ
The F-15J/DJ program was initiated in the late 1970s, with the Japanese government selecting the Boeing F-15 Eagle as the basis for its new air defense fighter. The decision was driven by the need for a highly advanced, long-range interceptor capable of countering the growing threat posed by the Soviet Union鈥檚 bomber fleet. The F-15J/DJ was designed to provide Japan with a formidable air defense system, leveraging the proven capabilities of the F-15 Eagle. The first F-15J/DJ aircraft were delivered to the JASDF in 1981, with the fleet reaching initial operational capability (IOC) in 1983.
Upgrades and Modernizations
Over the years, the F-15J/DJ has undergone numerous upgrades and modernizations to ensure it remains an effective and relevant component of Japan鈥檚 air defense strategy. One of the most significant upgrades was the Mid-Life Update (MLU) program, which commenced in the late 1990s and involved the installation of advanced avionics, radar, and missile systems. The MLU program enhanced the F-15J/DJ鈥檚 capabilities, enabling it to engage multiple targets at beyond-visual-range distances and improving its overall performance in a variety of mission scenarios. Additional upgrades have included the integration of advanced electronic warfare systems, improved radar capabilities, and the introduction of new missile systems, such as the AAM-4 and AAM-5.
