The OH-6A Cayuse was designed as a military scout aircraft during the Vietnam War to meet the Army's need for an extremely maneuverable light observation helicopter. Nicknamed the "Loach" because of its LOH designation (light observation helicopter), the OH-6 was heavily relied upon in Southeast Asia. At peak production during the war, as many as 100 OH-6As were built per month. The Cayuse was used for command and control, observation, target acquisition and reconnaissance.
