Northrop YF-23
The Northrop YF-23 is a prototype stealth fighter aircraft developed for the United States Air Force's Advanced Tactical Fighter program in the late 1980s. Designed by Northrop and McDonnell Douglas, it features a unique shape and advanced materials to reduce radar visibility. The YF-23 is powered by two Pratt & Whitney F119 engines, allowing for supercruise capabilities without afterburners.
First flown in 1990, the YF-23 competed against the Lockheed YF-22 for the contract to develop the next-generation air superiority fighter. Although it showcased impressive performance and stealth features, the YF-22 was ultimately selected, leading to the development of the F-22 Raptor.
