The Consolidated XB2Y was an American prototype single-engined dive bomber of the 1930s.
It was intended to meet a United States Navy requirement for a carrier-based dive bomber, but was unsuccessful, only a single example being built.
In 1932, the United States Navy issued a specification for a two-seat carrier-based dive bomber capable of carrying a 1,000 lb (450 kg) bomb.
Orders were placed for competing prototypes of designs to meet the Navy’s requirement with Consolidated Aircraft and the Great Lakes Aircraft Company in June 1932.
Consolidated’s proposal was the Model 24 (or XB2Y in the US Navy’s designation system), a single-bay biplane developed from a basic design prepared by the Navy’s Bureau of Aeronautics with detailed design led by Consolidated’s B Douglas Thomas, formerly Chief Designer of Thomas Morse Aircraft, which had become part of Consolidated Aircraft in 1929.
In order to withstand the high g-forces experienced during pullup after a dive attack, much of the aircraft’s center-section was cut from a solid steel block.
It was powered by a similar Pratt & Whitney R-1535 Twin Wasp Junior air-cooled radial engine as used by the Great Lakes design, and had a fixed tail wheel undercarriage.
The crew of two sat in tandem in separate cockpits, with the observer in the rear cockpit armed with a single flexibly mounted machine gun, and the pilot with a single fixed synchronized machine gun firing through the aircraft’s propeller arc.
Its bomb load was carried on a crutch under the fuselage that swung down to ensure the bomb would clear the propeller when dropped in a steep dive.
