Consolidated XP4Y Corregidor

The Consolidated XP4Y (company Model 31) 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.

Design and development

The Model 31 was a new flying boat design started in 1938, intended for both military 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)[1] and an upswept aft fuselage with a tail unit with twin endplate fins and rudders. It had retractable floats on the undersides of the wings and was powered by two of the new Wright R-3350 radial engines. The civil version could carry seats for 52 passengers, or sleeper accommodation for 28.[2]

The prototype Model 31 first flew on 5 May 1939, demonstrating excellent performance.[2] The Japanese attack on Pearl Harbor on 7 December 1941 brought America into the Second World War just as testing was complete and the United States Navy purchased the prototype, designated XP4Y-1, which was converted into a prototype patrol aircraft, fitted with nose, tail and dorsal gun turrets and 4,000 lb (1,820 kg) of external stores.[3]

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.[4]

Consolidated Aircraft

The Consolidated Aircraft Corporation was founded in 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Pacific and European theaters.

In 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair.

List of aircraft of World War II

The List of aircraft of World War II includes all the aircraft used by those countries, which were at war during World War II from the period between their joining the conflict and the conflict ending for them. Aircraft developed but not used operationally in the war are in the prototypes section at the end. Prototypes for aircraft that entered service under a different design number are ignored in favour of the service version. The date the aircraft entered service, or was first flown if the service date is unknown or it did not enter service follows the name, followed by the country of origin and major wartime users. Aircraft used for multiple roles are generally only listed under their primary role unless specialized versions were built for other roles. Aircraft used by neutral countries such as Spain, Switzerland and Sweden or countries which did no significant fighting such as most of those in South America (except Brazil), are not included.

The following is a list of bomber airplanes and does not include bomber airships, organized by era and manufacturer. A bomber is a military aircraft designed to attack ground or sea targets.

List of seaplanes and amphibious aircraft

The following is a list of seaplanes and amphibious aircraft, which includes floatplanes and flying boats, by country of origin.

Seaplanes are any aircraft that has the capability of landing on water while amphibious aircraft are equipped with wheels to alight on land, as well as being able to land on the water. Flying boats rely on the fuselage or hull for buoyancy, while floatplanes rely on external pontoons or floats. Some experimental aircraft used specially designed skis to skim across the water but did not always have a corresponding ability to float.

This list does not include ekranoplans, 'Wing-In-Ground-effect' (WIG), water-skimmers, wingships or similar vehicles reliant on ground effect.
