Hughes XF-11
На базе D-2, созданного в годы войны и облетанного в июле 1943 года на озере Харпер Лейк, компания "Hughes" создала опытный самолет-фоторазведчик XF-11, отличавшийся большой дальностью полета. Самолет представлял собой двухместный свободнонесущий высокоплан с двухмоторной силовой установкой и с килями на двух хвостовых балках. Были применены двигатели Pratt & Whitney R4360-31. Однако опытный самолет разбился во время полета - сам Хьюз едва не погиб.

The Hughes XF-11 Long-range Photographic-Reconnaissance Monoplane (two Pratt & Whitney R-4360-13 engines).
The XF-11 prototype 44-70155 pushed out to show its 101 ft 5 in. span high aspect ratio wing, twin booms and two man cockpit in the central nacelle. The fairings under the outer mainplanes were racks intended to carry 300 gal long-range fuel tanks but these were never fitted. -

This view of the first XF-11 shows the 8-blade contraprops and the almost full span flaps lowered to the take-off setting. The ailerons were small as they were combined with spoilers for lateral control.
