The Northrop XP-56 was designed as a competitor for a 1939 USAAC specification for a single-seat interceptor fighter, competing against the Curtiss-Wright XP-55, and the Vultee XP-54. Only two prototypes were made, and testing showed it to not only underperform, but be basically un-airworthy. The project was cancelled, but lessons learned from the XP-56 came in handy with later Northrop flying wing designs.
