Douglas YB-11
From Free net encyclopedia
The Douglas YB-11 was a bomber aircraft designed for the United States Army Air Corps. Although a prototype was built, it did not enter production.
In the early 1930s, the U.S. Army ordered the development of an amphibious observation plane, designated the Douglas YO-44, based on the U.S. Navy's Douglas XP3D seaplane. When the Army accepted the YO-44, it was redesignated YOA-5, 'observation amphibian model 5'. A version of the YOA-5 was converted to bomber duty and dubbed the YB-11. It was the only amphibian to carry a bomber designation.
