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.
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.

The Convair B-58 Hustler was a high-speed strategic bomber, capable of routinely attaining Mach 2 at altitude. It incorporated a large delta wing with a leading-edge sweep of 60°, and was powered by an arrangement of four General Electric J79-GE-1 turbojet engines.
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.
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 ...
The General Electric F404 and F412 are a family of afterburning turbofan engines in the 10,500–19,000 lbf (47–85 kN) class (static thrust). The series is produced by GE Aerospace . Partners include Volvo Aero , which builds the RM12 variant.
Two widely spaced General Electric J79 turbojet engines were supplied with air through inlets with variable intake ramps. [ 3 ] [ 14 ] While the same engine was used by several other US military aircraft, such as the Convair B-58 Hustler and the McDonnell Douglas F-4 Phantom II , the powerplants used on the A-5 differed in some ways, such as ...
