High Quality Content by WIKIPEDIA articles! The Douglas YOA-5 was an Amphibious aircraft designed for the United States Army Air Corps. Although a prototype was built, it did not enter production. In November 1932, the U.S. Army ordered the development of an amphibious reconnaissance aircraft/bomber, intended to act as navigation leaders and rescue aircraft for formations of conventional bombers. The resultant aircraft, which was ordered under the bomber designation YB-11, was designed in parallel with the similar but larger Douglas XP3D patrol flying boat for the United States Navy. It was a high winged monoplane with two Wright R-1820 Cyclone radial engines mounted in individual nacelles above the wing, resembling an enlarged version of the Douglas Dolphin.
