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.
Design and development
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.[1]
Prior to completion, it was redesignated firstly as an observation aircraft YO-44 and then as the YOA-5 'observation amphibian model 5'.[2] It first flew during January 1935, and was delivered to the army during February that year.[1] The concept for which it was designed proved impracticable, and no further production ensued, but the YOA-5 was used to set two world distance records for amphibians, being finally scrapped in December 1943.[3]
