The Douglas XFD was a carrier-based biplane fighter aircraft, the first fighter to be built by Douglas Aircraft Company.
The XFD was designed to the Bureau of Aeronautics Specification No. 311, requesting a carrier-based two-seat biplane fighter. On June 30, 1932, the Navy ordered the XFD, Vought XF3U, and Curtiss XF12C for testing. The XFD was all metal except for its fabric covering. The crew sat in tandem in a single bay, enclosed by a long canopy. It was fixed gear with a tailwheel. Powered by a Pratt & Whitney Wasp, it first flew in January 1933, and was evaluated by the Navy between June 18, 1933 and August 14, 1934. The XFD performed well, but the Navy had stopped using two-seat fighters; therefore, no orders were received.
