J79

The J79 is a single-shaft turbojet engine with afterburner. It has been manufactured by MTU under license from General Electric since 1970. The engine's first application was the Lockheed F104G Starfighter, and a modified version of the J79 has been powering the McDonnell Douglas F-4 Phantom II aircraft of the German armed forces since 1973.

Now that production has ended, MTU focuses on the repair and maintenance of the J79 engines, which is performed in Munich under the cooperation with the German Air Force.
