The T-37A "Tweet" trainer made its first flight in 1955 and went into service with the Air Force in 1956. The T-37 Tweet is a twin-engine jet used for training undergraduate pilots, undergraduate navigator and tactical navigator students in fundamentals of aircraft handling, and instrument, formation and night flying.
The Cessna A-37 was derived from the proven T-37 trainer in 1962. Two YAT-37D prototypes were produced from existing T-37s for evaluation by the United States Air Force in the counterinsurgency role. Combat tests in South Vietnam showed that the YAT-37D was underpowered. A decision was made to fit the A-37 with two General Electric J-85 turbojets. The new A-37A could double its takeoff weight and thus carry a larger bomb load. Five hundred seventy-seven A-37s were built. A-37s were used with great success in Southeast Asia. The South Vietnamese Air Force was also equipped with the Dragonfly.
The OA-37 Dragonfly derivative was an armed observation aircraft developed during the Vietnam War. The OA-37 "DRAGONFLY" replaced the aging O-2A in the early 1980s. It continued in use with Air Guard and Reserve units as observation platforms until the 1980s.
