The Douglas O-46 was an observation aircraft used by the United States Army Air Corps and the Philippine Army Air Corps. It developed from the Douglas O-43, whose 24th airframe was completed as the XO-46 prototype with a revised wing and a Pratt and Whitney Twin Wasp Junior radial engine in place of the inline unit. The Air Corps ordered 90 O-46As in 1935 and they were built between May 1936 and April 1937. It was the last of a long line of Douglas observation aircraft and was soon judged too slow and heavy for modern war, so it ended up in liaison, training and anti-submarine patrol duties. One airframe survives in the National Museum of the United States Air Force.
