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. [1] 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. [2] [3]
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, [2] formerly Chief Designer of Thomas Morse Aircraft, which had become part of Consolidated Aircraft in 1929. [4]
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. [2] [5] It was powered by a similar Pratt & Whitney R-1535 Twin Wasp Junior air-cooled radial engine as used by the Great Lakes design, [2] [3] and had a fixed tailwheel 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 bombload 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. [2]
The prototype XB2Y-1 (serial number 9221 [6] ) was completed in 1933, being delivered on 28 June 1933. [2] Testing was unsuccessful, [2] with the aircraft's performance being unsatisfactory, [7] while the aircraft also proved very expensive to build. [2] [5] The US Navy preferred the Great Lakes design, with 60 being ordered as BG-1s. [3]
The XB2Y-1 was modified to a scout configuration, removing the bomb crutch. This allowed it to reach a height of 23,400 ft (7,100 m), [2] and it was used by NACA at Langley, Virginia for pilot view tests. [8]

The Vought SB2U Vindicator is an American carrier-based dive bomber developed for the United States Navy in the 1930s, the first monoplane in this role. Vindicators still remained in service at the time of the Battle of Midway, but by 1943, all had been withdrawn to training units. It was known as the Chesapeake in Royal Navy service.
The Heinkel He 118 was a prototype German monoplane dive bomber design that lost out to the Junkers Ju 87 Stuka in the 1930s, and was never ordered by the Luftwaffe.
The Brewster SB2A Buccaneer is a single-engined mid-wing monoplane scout bomber aircraft built by the Brewster Aeronautical Corporation for the United States Navy between 1942 and 1944. It was also supplied to the Royal Air Force (RAF), United States Army Air Forces, and United States Marine Corps. The Buccaneer was overweight and lacked maneuverability, and has been described as a "classic failure." While designed as a scout bomber, none saw combat, although a number found use in noncombat roles.
The Curtiss SBC Helldiver was a two-seat scout bomber and dive bomber built by the Curtiss-Wright Corporation. It was the last combat military biplane procured by the United States Navy. Delivered in 1937, it became obsolete even before World War II and was kept well away from combat with Axis fighters.
The Naval Aircraft Factory SBN was a United States three-seat mid-wing monoplane scout bomber/torpedo aircraft designed by the Brewster Aeronautical Corporation and built under license by the Naval Aircraft Factory in Philadelphia, Pennsylvania. The landing gear was similar to that on the Brewster F2A Buffalo fighter aircraft. The SBN had non-folding wings with perforated flaps.
The Boeing XF8B was a single-engine aircraft developed by Boeing during World War II to provide the United States Navy with a long-range shipboard fighter aircraft. The XF8B was intended for operation against the Japanese home islands from aircraft carriers outside the range of Japanese land-based aircraft. Designed for various roles including interceptor, long-range escort fighter, dive-bomber, and torpedo bomber, the final design embodied a number of innovative features in order to accomplish the various roles. Despite its formidable capabilities, the XF8B-1 never entered series production.
The Vought XF3U was the prototype of a two-seat, all-metal biplane fighter, built by Vought Aircraft Company of Dallas, Texas for the United States Navy.
The Vought SBU-1 Corsair was a two-seat, all-metal biplane dive bomber built by Vought Aircraft Company of Dallas, Texas for the US Navy. Its design was based upon the F3U-1 two-seat fighter that was abandoned when the Navy decided not to obtain any more two-seat fighters.
The Northrop BT was an American two-seat, single-engine monoplane dive bomber built by the Northrop Corporation for the United States Navy. At the time, Northrop was a subsidiary of the Douglas Aircraft Company. While unsuccessful in its own right, the BT was subsequently redesigned into the Douglas SBD Dauntless, which would form the backbone of the Navy's dive bomber force.
The Vultee V-11 and V-12 were American stressed-skin monocoque monoplane attack aircraft of the 1930s. Developed from the Vultee V-1 single-engined airliner, the V-11 and V-12 were purchased by several nations for their armed forces, including China, who used them in combat against Japanese forces in the Second Sino-Japanese War. The United States Army Air Corps purchased seven V-11s as the YA-19 in the years before World War II, testing them to gather data to compare against twin engine light attack aircraft.
The Hall XPTBH was a prototype American twin-engined seaplane, submitted to the United States Navy by the Hall Aluminum Aircraft Corporation in response to a 1934 specification for new bomber and scout aircraft. Constructed in an innovative fashion that made extensive use of aluminum, the XPTBH proved successful in flight testing, but failed to win favor with the U.S. Navy. No production contract was awarded, and the single aircraft built served in experimental duties before its destruction in a hurricane during 1938.
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with 2 Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation.
The Boeing F3B was a biplane fighter and fighter bomber that served with the United States Navy from 1928 into the early 1930s.
The Douglas T2D was an American twin-engined torpedo bomber contracted by the military, and required to be usable on wheels or floats, and operating from aircraft carriers. It was the first twin-engined aircraft to be operated from an aircraft carrier.
The Grumman XSBF, also known by the company designation G-14, was an American biplane scout bomber developed by Grumman Aircraft for the United States Navy during the 1930s. Derived from Grumman's successful "Fifi" fighter, the aircraft was developed at a time when the biplane was giving way to the monoplane. In competition against other aircraft it proved to possess inferior performance in its intended role, and did not enter production. The sole prototype went on to serve as a liaison aircraft, as well as being used in experiments by NACA, before being destroyed in a crash in 1939.
The Great Lakes BG was an American carrier-based dive bomber of the 1930s. Designed and built by the Great Lakes Aircraft Company of Cleveland, Ohio, 61 were used by the United States Navy and United States Marine Corps from 1934 to 1940.
The Martin T4M was an American torpedo bomber of the 1920s. A development by the Glenn L. Martin Company of their earlier Martin T3M, and, like it a single-engined biplane, the T4M served as the standard torpedo bomber aboard the aircraft carriers of the United States Navy through much of the 1930s.
The Douglas XFD was a carrier-based biplane fighter aircraft designed for the United States Navy, and the first fighter to be built by the Douglas Aircraft Company. A victim of changing requirements, no production was undertaken.
The Northrop XFT was an American prototype fighter aircraft of the 1930s. A single engined low-winged monoplane, it was designed and built to meet a United States Navy order for an advanced carrier based fighter. It exhibited poor handling, and was rejected by the Navy, the single prototype being lost in a crash. A variant, the Northrop 3A, also was unsuccessful.
The Arado Ar 81 was a German prototype dive bomber. Because the Reich Air Ministry decided to purchase the competing Junkers Ju 87, only three prototypes of the Ar 81 were completed.
