The F-15J is a variant of the McDonnell Douglas F-15 Eagle licensed to Japan.
Though most of the fighters were identical to the base F-15, the U.S. withheld the engines and some avionics from the licensing agreement due to security concerns, allowing the Japanese to tailor the aircraft to their specific needs.
