Berliner-Joyce XFJ-2

The XFJ-1 was returned to Berliner-Joyce for reconstruction in November 1930, during which the dihedral was eliminated from the upper wing, the vertical tail surfaces were enlarged and a 500hp R-1340D Wasp engine was installed, this being enclosed by a Townend ring and fitted with a spinner.

Redesignated XFJ-2, the fighter resumed its flight test programme at Anacosta on 22 May 1931. The XFJ-2 displayed no improvement in landing characteristics by comparison with the XFJ-1 and proved unstable, and after testing by the US Navy, was discarded as unsatisfactory.
