TheDouglas XT3D was an American three-seattorpedo bomberbiplane developed by theDouglas Aircraft Company to meet aUnited States Navy requirement.[1]

Development

[edit]
The XT3D-1 with one wing folded.

The XT3D torpedo bomber (BuNo 8730) first flew in 1931.[1] It has been described as a "large and ugly" aircraft.[1] Of metal construction with afabric covering the XT3D had folding wings and an arrestor hook for carrier operation.[1] With a fixedtailwheel landing gear and powered by aPratt & Whitney R-1690 Hornetradial engine,[1] the XT3D had three open cockpits, forward for the gunner/bomb-aimer, center for the pilot, rear for another gunner.[1]

The XT3D failed to meet theUnited States Navy's requirements and after tests was returned to Douglas.[1] It was modified with a more powerfulPratt & 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 U.S. Navy trials and was not ordered into production.[1] 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.[1]

Variants

[edit]
The XT3D-2 in January 1933.
