The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
The production engines were fitted on the production F-22, and were first flown on the F-22's maiden flight on 7 September 1997. [ 8 ] [ 9 ] A total of 507 engines were produced. [ 10 ] The F119 Heavy Maintenance Center (HMC) for depot overhaul is located at Tinker Air Force Base, Oklahoma, with the first overall completed in 2013.
Yaw, pitch and roll authority would be accomplished through thrust-vectoring, possibly by modifying the extant 2-D vectoring nozzles of the F-22. These changes would in effect be combining the control and propulsion systems. [2] The X-44 MANTA would have a greater fuel capacity than the F-22, due to its larger delta wing design.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
The Advanced Tactical Fighter (ATF) was a program undertaken by the United States Air Force to develop a next-generation air superiority fighter to replace the F-15 Eagle in order to counter emerging worldwide threats in the 1980s, including Soviet Sukhoi Su-27 and Mikoyan MiG-29 fighters under development, Beriev A-50 airborne warning and control systems (AWACS), and increasingly ...

It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the F-15 Eagle. The engine was to be developed in tandem with the F401 which shares a similar core but with an upscaled fan for the U.S. Navy's F-14 Tomcat. The F401 was later abandoned due to costs and reliability issues.
