HISTORY OF S/N 59-2631: This is the last known flying B model OV-1 Mohawk. The OV-1B Mohawk was developed by the Army to be able to carry the eighteen foot SIDE LOOKING AERIAL RADAR (SLAR) pod while retaining the photographic capabilities of the earlier OV-1A Mohawk. The SLAR provided a film record of ground radar images on both sides of the aircraft’s flight path of moving targets at night and in bad weather. This system was used successfully in patrolling the West German border and in Vietnam. To compensate for the weight and increased drag of the SLAR pod, the OV–1B model received more powerful engines and increased wing span. The OV-1B had 5 feet of wing added to improve lift and engine horsepower increased by 100 shp per engine. The U.S. Army had 90 OV-1Bs built. The Mohawk is the fastest turboprop ever operated by the Army and served in reconnaissance and armed attack versions. The aircraft is painted in its U.S. Army markings when it first went into operational service in 1962 in Hanau, West Germany with the 503rd Aviation Battalion, 3rd Armored Division providing surveillance work along the German border. The aircraft has performed extensively since 2002 on the U.S. air show circuit with the Sky Soldiers Demonstration Team of the Army Aviation Heritage Foundation (AAHF). Our aircraft was released from Army (National Guard) service in 1985. 1962–1965: 503RD AVN. BN., 3RD Armored Div., (Hanau, W.

Rucker,AL 1886–1999: Private Owner 1999 to present: Army Aviation Heritage Foundation HISTORY OF OV-1B MOHAWK: In June of 1956, the Army had a requirement for a two seat, twin turboprop aircraft designed to operate from small, unimproved fields under all weather conditions to perform the missions of observation, artillery spotting, air control, and liaison. The GRUMMAM AIRCRAFT CORPORATION was awarded the Tri–Service contract with it’s entry of the OV–1 Mohawk. The Army took delivery of it’s first OV–1A Mohawk in February of 1961 with total deliveries of 380 OV–1’s in four different A–D models. MOHAWKS were initially deployed to South Vietnam in 1962 and served throughout the entire conflict. The Mohawk was used for visual and photographic reconnaissance with great success due to the aircraft’s speed and quiet turbo–prop engines. The aircraft was also utilized with success in the light attack role when armed with 2.75 inch rockets and .50 caliber machine guns. In late 1966, an armed OV–1A of the 131st S.A.C. shot down a North Vietnamese Air Force MIG–17 over North Vietnam. The Mohawk was removed from Army service in the mid 1990’s with the last Mohawk unit being the 224th Military Intelligence Battalion based at Hunter Army Airfield, Georgia. PRICE REDUCED!
