Cessna O-2 Skymaster

The Cessna O-2 Skymaster, nicknamed the Oscar Deuce, is the military version of the Cessna 337 Super Skymaster, used for forward air control and psychological operations by the United States military between 1967 and 2010. In 1966 the United States Air Force commissioned Cessna to build a variant of the Model 337 to supplement the Cessna O-1 Bird Dog in the forward air control role. The O-2 first flew in January 1967 and went into production that March, when the Air Force took delivery. Added antennae and a significant weight increase reduced performance, especially at cruising altitude, but it was judged sufficient for the expected low-level operation. Two 210 horsepower Continental IO-360 engines power it. Production stopped in June 1970 after 532 had been built for the Air Force.
