In 1957, the U.S. Army identified a requirement for a light but rugged front-line observation aircraft that could operate from rough airstrips and had short take-off and landing (STOL) capability. Grumman's proposal was accepted, and development of the YAO-1A began.
The aircraft's first flight was 14 April 1959. It was a mid-wing monoplane powered by two turboprop engines, with a tail featuring three vertical stabilizers. The pilot and observer sat in a side-by-side cockpit with bulged side windows, providing excellent downward visibility.
Three production versions were ordered: the AO-1A, exclusively for day-time and night-time reconnaissance; the AO-1 B, with a Sideways Looking Radar (SLAR) pod slung under the right side of the fuselage; and the AO-1 C, designed for infra-red reconnaissance. These designations were later changed to OV-1A, OV-1B and OV-1C, respectively. An OV-1 0 version was developed later, which combined the capabilities of the OV-1 Band OV-1 C.
More than 375 OV-1s were built over a period of almost 10 years. They were used extensively in the Vietnam War. The aircraft was not designed to carry armament, but many were modified in the field to carry rockets, mortars, rotating-barrel machine guns and small missiles, in addition to iron bombs.
Planes of Fame Air Museum's OV-1A was donated in 2006, and was flown to Chino in 2007.
