Having a semi-monocoque stressed-skin fuselage with fabric-covered metal wings, the XFJ-1 single-seat experimental
shipboard fighter featured an upper wing
faired into the fuselage which was strut-braced above
the lower wing. Proposed armament comprised two
7.62mm synchronised machine guns and
power was provided by a 450hp Pratt & Whitney
R-1340C Wasp nine-cylinder radial air-cooled engine.
The XFJ-1 was ordered on 16 May 1929, and flown for the first time in May 1930, but evinced extremely poor
landing characteristics and was damaged in a landing
accident at Anacostia early in its flight programme. It
was returned to the Berliner-Joyce Corporation in
November 1930 for reconstruction and modification, reappearing
as the XFJ-2.
