The Grumman XF5F Skyrocket was a prototype twin-engined carrier fighter notable for a fuselage nose that stopped level with the wing leading edge.

WEFT is AircraftIQ's four-point recognition method — how it works.

Its short, blunt nose set well back from the propellers, flanked by two closely mounted engine nacelles, makes it one of the odder-looking American fighters of its era.

History

Ordered by the US Navy in June 1938 as a lightweight interceptor, the XF5F paired two Wright R-1820 engines with opposite-rotating propellers for a high rate of climb, first flying on 1 April 1940. Extensive changes to fix handling problems delayed final testing until January 1942.

Variants

The design's lessons carried directly into Grumman's larger and more successful twin-engined XF7F Tigercat.

Where you'll see it

The XF5F never entered production or squadron service and no example survives today; it is remembered as a technical stepping stone to the Tigercat.
