604th Direct Air Support Squadron

The 604th Direct Air Support Squadron was a United States Air Force unit activated during the Vietnam War. Established in 1966, it was tasked with providing direct air support and coordination between ground forces and tactical air assets. Stationed primarily at Bien Hoa Air Base, South Vietnam, the squadron played a vital role in facilitating close air support missions for U.S. Army and allied units. The 604th contributed significantly to the effectiveness of air-ground operations until its inactivation in 1972 following the drawdown of U.S. combat forces in Southeast Asia.
