Douglas XT3D was an American three-seat torpedo bomber biplane developed by the Douglas Aircraft Company to meet a United States Navy requirement. [1 ]
Development [ edit ]
The XT3D-1 with one wing folded.
The XT3D torpedo bomber (
BuNo 8730) was first flown in 1931, it has been described as a large and ugly aircraft. Of metal construction with a [1 ] fabric covering the XT3D had folding wings and an arrestor hook for carrier operation. With a fixed [1 ] tailwheel landing gear and powered by a Pratt & Whitney R-1690 Hornet radial engine, the XT3D had three open cockpits, forward for the gunner/bomb-aimer, centre for the pilot, rear for another gunner. [1 ] [1 ]
The XT3D failed to meet the Navy's requirements and after tests was returned to Douglas.
It was modified with a more powerful [1 ] Pratt & Whitney XR-1830-54 radial, and wheel fairings and the two rear cockpits were enclosed. Re-designated XT3D-2, it still failed to pass Navy trials and was not ordered into production. [1 ] The prototype was used by the Navy for the next ten years for general purpose use until it was relegated as an instructional airframe in 1941. [1 ] [1 ]
