The Douglas YB-11 was based on the U.S. Navy XP3D-1 seaplane. The Air Corps ordered a scaled-down version of the aircraft incorporating design changes for amphibious operation (on land and sea). The aircraft was redesignated as an observation plane (YO-44) before construction was completed. The plane was again redesignated as an observation amphibian (YOA-5) when the Air Corps accepted it.

The YB-11 was the only amphibian ever to carry an Army Air Corps bomber designation.
