The development of the J79 turbojet began in 1952 as a more powerful follow-up to the General Electric J47 turbojet. The engine generated a maximum of 17,000 pounds of thrust with the afterburner operating.

The J79 was used on a variety of high-speed aircraft, including some of the advanced fighters developed during the late 1950s. The two most famous examples are the McDonnell Douglas F-4 and Lockheed F-104, which were both capable of flying at Mach 2.
