The General Electric J79 is an axial-flow turbojet engine built for use in a variety of fighter and bomber aircraft and a supersonic cruise missile. The J79 was produced by General Electric Aircraft Engines in the United States, and under license by several other companies worldwide.
In 1967 the 319th F-104As and Bs were re-engined with the J79-GE-19 engines with 17,900 lbf (79.6 kN) of thrust in afterburner; service ceiling with this engine was in excess of 73,000 ft (22,250 m). In 1969, all the F-104A/Bs in ADC service were retired. On 18 May 1958, an F-104A set a world speed record of 1,404.19 mph (2,259.82 km/h). [3]
The LM1500 was derived from the J79 engine in 1960. [3] Its first application was for the first US sea-going research hydrofoil, HS Denison. [1] Conversion as a marinised turboshaft engine involved two major changes: the addition of a free power turbine, and corrosion-protection by the addition of internal coatings and a maintenance scheme of freshwater rinsing to prevent salt damage.
The YJ93 started life as the General Electric J79-X275, an enlarged version of the General Electric J79 turbojet with "275" meaning Mach 2.75, the engine's target operating speed. [2] This design evolved into the X279 when Mach 3 cruise became a requirement, and ultimately became the YJ93. [3] The engine used a special high-temperature JP-6 fuel.
This was the result of a 1955 study to fit the new General Electric J79 engine into the F11F airframe. The Navy was sufficiently interested to authorize modification of two production F11F-1s with enlarged air intakes and YJ79-GE-3 turbojets, with the result being designated the F11F-1F, indicating a production F11F-1 with a special engine fit.

GE adopted the second option with their General Electric J79, while Pratt & Whitney adopted the two-spool arrangement with their J57. P&W realized that if they could develop a modest pressure ratio (< 4.5:1) axial compressor to handle adequately at any throttle setting including starting and acceleration, they could put two such compressors in ...
