Japanese F-15JSI Fighters to get Electronic Warfare Systems

Boeing has won nearly $25 million to equip F-15JSI ‘Japanese Super Interceptor’ aircraft with Electronic Warfare systems.

The modification provides for the Foreign Military Sales requirement to add electronic warfare system initial non-recurring engineering for the Japan Air Self Defense Force (JASDF), a U.S. DoD release today said.

Work will be performed in St. Louis, Missouri, and is expected to be completed by Dec. 31, 2028.

In late October 2019, the U.S. State Department approved the Japanese government’s plan to spend up to $4.5 billion to upgrade 98 Boeing F-15J fighters to the JSI standard. Currently, only 70 fighters will receive extensive upgrades under the program. The earlier plan to upgrade 98 jets was dropped to save costs.

Also cut was a plan to integrate AGM-158 Joint Air-to-Surface Standoff Missiles (JASSM) with the upgraded F-15. Tokyo is developing an anti-ship variant of the Mitsubishi ASM-3 air-to-air missile. It could arm the upgraded F-15s with these.
