The 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
The XT3D torpedo bomber (BuNo 8730) was first flown in 1931, it has been described as a large and ugly aircraft.[1] Of metal construction with a fabric covering the XT3D had folding wings and an arrestor hook for carrier operation.[1] With a fixed tailwheel landing gear and powered by a Pratt & Whitney R-1690 Hornet radial engine,[1] the XT3D had three open cockpits, forward for the gunner/bomb-aimer, centre for the pilot, rear for another gunner.[1]
The XT3D failed to meet the Navy's requirements and after tests was returned to Douglas.[1] It was modified with a more powerful Pratt & Whitney XR-1830-54 radial, and wheel fairings and the two rear cockpits were enclosed.[1] 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]
