The initial prototype was lost in September 1946; the aircraft had been
refitted to test ramjet engines underwing, and on this occasion one of
the engines caught fire, forcing the pilot and test engineer to bail
out. The second aircraft had a larger tail to counter stability
problems, but after a short life this example was scrapped.
Armament options for production aircraft would have been 6x.50-cal M2s,
an equal number of .60-cal T17E3s, a quartet of 20mm Hispanos, or a
single 30mm cannon.
