Japan Selects F-15EX for Next Fighter Upgrade Program

Japan’s Ministry of Defense has selected the Boeing F-15EX Eagle II to modernize its aging fleet of F-15J interceptors. The agreement, valued at approximately $8.2 billion, will see 48 new aircraft delivered between 2027 and 2032.

The F-15EX features advanced avionics, upgraded radar systems, and the ability to carry hypersonic weapons. Japan’s Air Self-Defense Force currently operates over 150 F-15J aircraft, many of which entered service in the 1980s.

“The F-15EX provides Japan with a proven platform enhanced by cutting-edge technology,” said Defense Minister Takeshi Iwaya. “This acquisition strengthens our defensive capabilities while ensuring interoperability with U.S. forces.”

The deal includes provisions for Japanese industry participation, with Mitsubishi Heavy Industries producing major subassemblies and providing depot-level maintenance support. Approximately 40 percent of each aircraft’s content will be manufactured in Japan.

Initial pilot training will begin in the United States in 2026, with Japanese instructors eventually establishing a domestic training program at Komatsu Air Base.
