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. The overall test objective was to ...
Flight testing for the F-22 continued until 2005, and on 15 December 2005 the USAF announced that the Raptor had reached its initial operational capability (IOC); with the collapse of the Soviet Union and the Department of Defense focused on counterinsurgency at that time, F-22 production only reached 195 aircraft and ended in 2011.

In order to fly the F-22, Larson said he had to go through basic pilot training, consisting of 55 weeks of flying in trainer aircraft like the T-6 Texan II and a T-38 Talon.
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 NGAD originated from Defense Advanced Research Project Agency studies initiated in 2014 to explore concepts for air superiority systems of the 2030s for the U.S. Air Force and U.S. Navy. DARPA completed its Air Dominance Initiative study in March 2014 and based on the results, the Department of Defense acquisition chief Frank Kendall launched the Aerospace Innovation Initiative (AII) in ...

The Boeing F-15EX Eagle II is an American all-weather multirole strike fighter derived from the McDonnell Douglas F-15E Strike Eagle.The aircraft resulted from the U.S. Department of Defense's Cost Assessment and Program Evaluation (OSD CAPE) study in 2018 to recapitalize the aging F-15C/D fleet due to inadequate numbers of F-22s, delays in the F-35 program, and maintaining diversity in the U ...
