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.
An F-22 Raptor assigned to the 411th Flight Test Squadron flies over Edwards Air Force Base, California, in 2018. The squadron successfully tested the F-22 flying on a 50/50 fuel blend of conventional petroleum-based JP-8 and biofuel derived from camelina , a weed-like plant not used for food, in March 2011.
Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The Lockheed Martin F-22 Raptor has chines along its nose section that align with its engine air intakes. [2] The small horizontal surfaces forming a fillet between the forward wing root and the air intake is more usually called a leading edge root extension (LERX) or leading-edge extension (LEX).
The last of 3,620 F-16s was built there in late 2017 after more than 39 years and then production moved to another factory in Greenville, South Carolina. In March 1992 Lockheed began to produce F-22 Raptor aircraft components at the facility. Additionally, the plant produces spare aircraft parts, radar units, and missile components. [8]
