Designated as an Assault Drone, the plywood skinned BQ-2A was powered by 2 x Lycoming R-680-13 engines of 300 hp each. A 2000 lb bomb could be carried in a compartment just aft of the wing. It shares the Fleetwings Model 37 number with the XBQ-1 and has the same airframe, however the fixed landing gear was jettisonable for better performance. A TV camera mounted in the LH wing leading edge allowed its guidance onto target from a mother-ship. First flight was on 21 August 1943. The design was deemed to be too expensive for operational use, so the program was cancelled in December 1943.

USAAF photo of a rare type, the first of only four XC-108 conversions. Originally delivered as a B-17E in Feb 1942, it was converted into the XC-108 VIP transport in 1943, to serve as General Douglas MacArthur's personal aircraft, named "Bataan". Armament and armor was removed, and it was fitted with a B-17F plexiglas nose with a single machine gun with a chrome barrel. The cabin was fitted with seats, tables, cooking facilities and extra windows for use as a flying living and office space. In Oct 1945 the aircraft was stored for disposal at Walnut Ridge, AR and sold for scrap in Sep 1946.
