The Atlantic (Fokker) XB-8 was ordered by the U.S. Army as a bomber derivative of the YO-27 observation aircraft design. The second prototype YO-27 was converted during assembly to a bomber configuration. The Douglas XB-7 was ordered at the same time and was a derivative of the YO-35 observation plane. The XB-8 was much faster than the existing Keystone bombers already in service, but couldn't carry a heavy enough bomb load to be considered for production. Six service test aircraft were ordered as YB-8 and Y1B-8, but all were delivered as Y1O-27s.
