Boeing Wins $474.5M to Provide EW Systems for Japanese F-15J Fighters

The Pentagon announced today a $474.5 million contract awarded to Boeing for the provision of electronic warfare systems for the F-15 Japan Super Interceptor (JSI) Program.

This contract fulfills the Foreign Military Sales (FMS) requirement to integrate the Eagle Passive Warning Survivability System (EPAWSS) into the Japan Air Self-Defense Force's aircraft, as stated in a Pentagon press release.

The work will be conducted in St. Louis, Missouri, and is expected to be completed by December 31, 2028. EPAWSS, developed, produced, and integrated through a strong partnership between Boeing and BAE Systems, enhances the protection of U.S. Air Force F-15s with advanced digital electronic warfare technology. This technology aims to maximize mission effectiveness and survivability in highly contested environments.

F-15 Japan Super Interceptor (JSI) Program

Mitsubishi Heavy Industries (MHI) produced the current Japan F-15J fleet of over 200 aircraft under license between 1980 and 2000. MHI will also serve as the prime contractor for the upgrade.

Under the $4.5 billion modernization program, 98 F-15J aircraft will be upgraded to the JSI configuration, introducing electronic warfare systems and enhanced weaponry. The upgrade will also include an all-new advanced cockpit system, powered by the world's most advanced mission computer, providing pilots with improved situational awareness.

Currently, Tokyo operates over two hundred F-15J (single-seat) and F-15DJ (two-seat) airframes. These aircraft, based on the American F-15C, were manufactured under license by MHI.
