However, Curtiss was requested to adapt the airframe for the turbo-supercharged 2,300 hp Wright XR-3350-16 two-row eighteen cylinder air-cooled radial engine, driving a six-bladed contra-propeller. Designated XF14C-2, the aircraft was flown in September 1943, but not delivered to the USN until July 1944. The XF14C-2 performance, too, was below manufacturer's guarantees, and with the tide of war in the Pacific running in favor of the USA, the altitude capability needs diminished.
Subsequently the XF14C-2 program, Curtiss last propeller-driven fighter, was canceled.
