The O-2 is the military version of the Cessna Model 337 Super Skymaster. It was selected by the Air Force in 1966 to augment the Cessna O-1 Bird Dog forward air controller aircraft then operating in Southeast Asia. The O-2 was produced in two variants: the lightly-armed A model for forward air control duties and the unarmed B model for psychological warfare operations. By the time production ended in June 1970, the Air Force had received 532 O-2 aircraft.

This O-2A, S/N 67-21411, is on loan to Octave Chanute Aerospace Museum from the National Museum of the United States Airforce.
