variants with their own articles=The Consolidated XP4Y was an American twin-engined long-range maritime patrol flying boat built by Consolidated Aircraft for the United States Navy. Only one was built and a production order for 200 was cancelled.

The Consolidated Model 31 was a new flying boat design started in 1938, intended for both miltary and commercial use. The aircraft was of all-metal construction with a high-mounted, high aspect ratio cantilever monoplane wing (the Davis wing, which was later used in the B-24 Liberator) [ Donald, David, ed. "Encyclopedia of World Aircraft" (Etobicoke, ON: Prospero Books, 1997), p.266.] and an upswept aft fuselage with a tail unit fitted with twin endplate fin and rudders. It had retractable floats on the undersides of the wings and was powered by two of the new Wight Duplex Cyclone radial engines. The civil version could carry seats for 52 passengers, or sleeper accomodation for 28. Wegg 1990, p.81.]

The prototype Model 31 first flew on May 5, 1939, demonstrating excellent performance. The Japanese attack on Pearl Harbor on December 7, 1941 brought America into the Second World War just as testing was complete and the United States Navy purchased the prototype, designated as the XP4Y-1, which was converted into a prototype patrol flying-boat fitted with nose, tail and dorsal gun turrets and 4,000 lb (1,820 kg) of external stores. Green 1962, pp.164-165.]

A production order for 200 P4Y-1 was placed in October 1942, with a new aircraft plant which had been constructed at New Orleans, Louisiana to build the aircraft. Delays in preparation of the prototype and the shortage of Wright Duplex Cyclone engines (which were required to power the B-29 Superfortress) led to the production order being cancelled, with the factory being used to build the PBY, instead. Wegg 1990, p.82.]
