The Douglas O-2 was a 1920s American observation aircraft built by the Douglas Aircraft Company, powered by the Liberty engine of WW1 fame, with some later variants using other engines. It was developed into several versions, with 879 being produced in total. It was used in combat by the Chinese Air Force in the 1930s and also was the basis for a successful mailplane version.
