About this Unit
AVDAC Long Binh was an Aviation Detachment and Aircraft Control unit operated by the United States Army during the Vietnam War, stationed at Long Binh Post, South Vietnam. Established to provide vital aviation logistical support, AVDAC (Aviation Direct Aircraft Support Command) was responsible for aircraft maintenance, supply, and technical assistance for Army aviation assets in the III Corps Tactical Zone. At its operational peak, AVDAC Long Binh played a critical role in ensuring the readiness and sustainability of helicopters and fixed-wing aircraft, which were essential for combat and support missions. The unit remained active until the drawdown of American forces, contributing significantly to the overall air mobility and effectiveness of U.S. operations in Vietnam.
