The Pogo had delta wings and three-bladed contra-rotating propellers powered by a turboprop engine. It was intended to be a high-performance fighter aircraft capable of operating from small warships. Landing the XFY-1 was difficult, as the pilot had to look over his shoulder while carefully working the throttle to land. After World War II, the Cold War prompted the United States Army and Navy to study VTOL operations. It was envisaged to protect task forces, convoys or any fleet, even without aircraft carriers, by placing VTOLs on any ship. These fighters would be housed within a conical protective housing, saving limited deck space available aboard ships. They would provide first line of airborne defense and reconnaissance capability, before more aircraft could be scrambled to help. The XFY-1 was designed for the Allison XT40-A-14 turboprop, which was expected to deliver 7,100 shp (5,295 kW). The production aircraft were intended to use the even more powerful Allison T54 which was never built. It was one of the few propeller-driven aircraft with delta wings, swept at 52 degrees, and a fin with a span of 21 ft 8 in (6.5 m). The pilot's seat was mounted on gimbals allowing for movement from 45 degrees in vertical flight to 90 degrees in horizontal flight. The Curtiss-Wright turbo-electric three-bladed contra-rotating propellers were 16 feet (4.88 m) in diameter. Only one xample was produced.
