The Cessna L-19/O-1 Bird Dog was a liaison and observation aircraft. It was the first all-metal fixed-wing aircraft ordered for and by the United States Army since the U.S. Army Air Forces separated from the Army in 1947, becoming its own branch of service, the United States Air Force. The Bird Dog had a lengthy career in the U.S. military, as well as in other countries.

During the Vietnam War the Bird Dog was used primarily for reconnaissance, target acquisition, artillery adjustment, radio relay, convoy escort and the forward air control of tactical aircraft, to include bombers operating in a tactical role.
