Douglas XT3D
The Douglas XT3D was an American three-seat torpedo bomber biplane developed by the Douglas Aircraft Company to meet a United States Navy requirement.
Development
The XT3D torpedo bomber first flew in 1931. It has been described as a "large and ugly" aircraft. Of metal construction with a fabric covering the XT3D had folding wings and an arrestor hook for carrier operation. With a fixed 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, center for the pilot, rear for another gunner.The XT3D failed to meet the United States Navy's requirements and after tests was returned to Douglas. It was modified with a more powerful 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 U.S. Navy trials and was not ordered into production. The U.S. Navy used the prototype for the next ten years as a general-purpose aircraft until relegating it to use as an instructional airframe in 1941.
