Grumman XF5F-1 / XP-50 Skyrocket
The Grumman XF5F Skyrocket was a prototype twin-engine shipboard fighter interceptor.
The United States Navy ordered one prototype, model number G-34, from Grumman Aircraft Engineering Corporation on 30 June 1938; its designation was XF5F-1.
The aircraft had a unique appearance:
The forward “nose” of the fuselage did not extend forward of the wing.
Provisions were included for two 20 mm (0.906 in) Madsen cannon as armament.
Only one was built.
The Grumman XP-50 was a land-based development of the shipboard XF5F-1 Skyrocket fighter, entered into a United States Army Air Corps contest for a twin-engine heavy interceptor aircraft.
The USAAC placed an order for a prototype on 25 November 1939, designating it XP-50, but it lost the competition to the Lockheed XP-49.
