The Douglas TB2D Skypirate (also known as the Devastator II) was a torpedo bomber intended for service with the United States Navy's Midway class aircraft carriers; they were too large for earlier decks. Two prototypes were completed, but the dedicated torpedo bomber was becoming an outdated concept and with the end of World War II, the type was no longer needed, resulting in the project's cancellation.

Design and development

In 1939, Douglas designers, Ed Heinemann and Bob Donovan began work on a VTB Proposal to replace the TBD Devastator torpedo bomber. In 1942, the team led by Heinemann and Donovan began work on a new project named the "Devastator II". On 31 October 1943, just four days after the new Midway class aircraft carriers were ordered into production, Douglas received a contract for two prototypes, designated TB2D, receiving the official name: "Skypirate". The TB2D was powered by a Pratt & Whitney R-4360 Wasp Major driving contra-rotating propellers. Four torpedoes or an equivalent bomb load could be carried on underwing pylons. Defensive armament consisted of two 20 mm (.79 in) cannon in the wings and .50 in (12.7 mm) machine guns mounted in a power-operated dorsal turret.

Very large for a single-engined aircraft, the TB2D would have been the largest piston-engined carrierborne aircraft at the time if it had been deployed. It could carry four times the weapon load of the TBF Avenger and was larger, heavier and faster than a B-25 Mitchell bomber. With only limited support from the US Navy, and facing a recommendation for cancellation on 20 May 1944 due to the aircraft being designed only for the CVB and CV9 carriers, the TB2B project was in peril even at the design and mock-up stage.

The two "Skypirate" prototypes, BuNo 36933 and 36934 were ready for flight trials in 1945 with the first prototype XTB2D-1 flying on 13 March 1945. The second example had a 58 cm increase in the length of the fuselage, and flew later in summer 1945. Both prototypes were test flown without any armament. Despite the flying trials proceeding on schedule, the collapse of the Japanese forces in the Pacific along with delays in the Midway class, eliminated the need for the type and the 23 pre-production aircraft on order were subsequently cancelled. The flight trials were suspended and the two prototypes were eventually reduced to scrap in 1948.
