TheDouglas XTB2D Skypirate (also known as theDevastator II) was atorpedo bomber intended for service with theUnited States Navy'sMidway- andEssex-classaircraft carriers; it was too large for earlier decks. Two prototypes were completed, but the dedicated torpedo bomber was becoming an outdated concept, and with the end ofWorld War II, the type was deemed unnecessary and cancelled.
In 1939, Douglas designersEd Heinemann and Bob Donovan began work on a VTB Proposal to replace theTBD 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 very largeMidway-classaircraft carriers were ordered into production, Douglas received a contract for two prototypes, designated TB2D, receiving the official name: "Skypirate".[1]
The TB2D was powered by aPratt & Whitney R-4360 Wasp Major drivingcontra-rotating propellers. Fourtorpedoes (such as theMark 13 torpedo) 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.[2]
Very large for a single-engined aircraft, the TB2D would have been the largestcarrierborne aircraft at the time; it could carry four times the weapon load of theGrumman TBF Avenger. 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 theCVB carriers, the TB2D project was in peril even at the design and mockup stage.[3]
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 theMidway 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.[4]
