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 (-15 version) with the afterburner operating.
The engine was used on the Convair B-58 Hustler, the first U.S. bomber capable of maintaining speeds in excess of Mach 2. The J79 also was used some 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.
