The Douglas O-43 was a monoplane observation aircraft used by the United States Army Air Corps.
Development[]
Five Y1O-31A service-test aircraft were ordered in 1931, and delivered to the USAAC in early 1933 designated Y1O-43. They differed from the final configuration of the O-31A, with a wire-braced parasol wing, and a new fin and rudder. An order for 23 O-43A aircraft was completed during 1934, with a deepened fuselage, which eliminated the need for the ventral bulge under the observer's position. Powered by a single 675 hp Curtiss V-1570-59 inline engine, it also had taller vertical surfaces with an inset rudder similar to the O-31A. The canopy was enlarged, and fully enclosed both cockpits. The O-43 and O-43A served with the USSAC observation squadrons for several years before being assigned to National Guard units,[2] such as the 111th Observation Squadron Brownwood Airfield Texas, 15th Observation Squadron Fort Sill Oklahoma, and 3rd Observation Squadron Langley Field Virginia.
The 24th airframe of the O-43A contract was completed as the XO-46 prototype (see Douglas O-46).
