F-19 is a designation for a United States fighter aircraft that has never been officially used, and has engendered much speculation that it might refer to a type of aircraft whose existence is still classified.


Since the unification of the numbering system in 1962, U.S. fighters have been designated by consecutive numbers, beginning with the F-1 Fury. F-13 was never assigned due to superstition, but after the F/A-18 Hornet, the next announced aircraft was the F-20 Tigershark. There have been a number of theories put forth to explain this omission, but none have ever been confirmed.

The most prevalent theory in the 1980s was that "F-19" was the designation of the stealth fighter whose development was an open secret in the aerospace community. When the actual aircraft was publicly revealed in 1988, it was called the F-117 Nighthawk. There seems to be no evidence that "F-19" was ever used to designate the Nighthawk, although the National Museum of the United States Air Force website (as of 2007) does include the entry "Lockheed F-19 CSIRS (see F-117)".
