The Northrop/McDonnell Douglas YF-23 Black Widow II was an Advanced Tactical Fighter demonstrator family built by the Northrop and McDonnell Douglas contractor team for the U.S. Air Force. Its distinctive diamond wing, canted tails, and low-observable design explored a stealthy high-speed air-dominance concept; the two prototypes flew in 1990 before the competing YF-22 was selected for development.
