Powered by two turbocharged Wright R-1820-67/69 engines, it was intended to carry an armament of two 0.787 in (20 mm) cannon and two 0.50 in (12.7 mm) machine guns. The XP-50 flew for the first time on May 14, 1941, but the aircraft was destroyed after 20 hours of flight testing as a result of a turbo-supercharger explosion. Further development was abandoned in favor of the more advanced XP-65 (Model G-51), which, in the event, was also to be discontinued."
