The Mohawk was designed to meet combined US Army and US. Marine Corps requirements of the mid 1950s for a battlefield surveillance plane. The type first flew in prototype from April 1959, offering high survivability though features such as aluminum armor, bulletproof windscreens, and flak curtains on fore and aft bulkheads, to gather with very considerable agility. The marines then pulled out of the program, leaving the army to order the OV-1A for optical reconnaissance with cameras and the OV-1B for electronic reconnaissance with side looking airborne radar and span increased by 6 ft. The Mohawk proved its capabilities in the Vietnam War, where some aircraft were fitted with hard points for four light armament. This capability was rarely used, however for the Mohawk real utility lies in its reconnaissance facility, which is much improved and diversified in later variants. total production was 329 aircraft.
