In 1941 the US Navy requested a better-performing carrier-based fighter plane, to be powered by the proposed high performance 24-cylinder liquid cooled Lycoming XH-2470 Hyper engine. This was an unusual step for the Navy, which had been adamant to that time that all its aircraft use air-cooled radial engines.
Early in the development the Navy requested better altitude performance and, in view of unsatisfactory progress in the development of the XH-2470 engine, Curtiss adapted the design of the aircraft around the new turbochargedWright R-3350 Duplex-Cyclone air-cooled radial engine. The aircraft equipped with this eighteen-cylinder twin-row radialair-cooled engine and three bladed contra-rotating propellers was designated the XF14C-2. The XF14C-1 was canceled. Also, looking at the problems of operation at altitudes of about 40,000 feet (12,000 m), the Navy also initiated work on a third version with a pressurized cockpit designated the XF14C-3.
Ultimately, only the XF14C-2 prototype was completed, flying for the first time in July 1944. Moreover, disappointment with performance estimates and delays with the availability of the XR-3350-16 engine coupled with the evaporating tactical need for an extremely high-altitude fighter led to cancellation of the development.
