Binh Thuy Air Base is a former air force base in Vietnam, It was constructed by the United States in 1965 and used by the South Vietnamese Air Force (SVNAF) and the United States Air Force during the Vietnam War in the IV Corps Tactical Zone of South Vietnam. It was seized by the Vietnam People's Army in April 1975 and was abandoned for several decades. Today, the site is being redeveloped as Trà Nóc Airport.

Binh Thuy Air Base was the most southern airbase used by the VNAF and USAF in Vietnam during the Vietnam War. Plans for a United States Air Force Base at Binh Thuy were developed in 1964 after the 1964 Gulf of Tonkin Resolution and the decision to deploy large numbers of United States forces to South Vietnam. The base was one of several air bases in the former South Vietnam built by United States Air Force RED HORSE civil engineering squadrons. The airfield was designed as a replacement for the ARVN Can Tho airfield which was located nearly in the heart of the city of Cần Thơ and had no room for expansion. In 1964 construction began on Binh Thuy Air Base on paddy fields that had to be drained and solidified with fill material.

Enough construction was complete that the SVNAF 74th Tactical Wing at Can Tho was moved to Binh Thuy on 1 September 1965. Air units were simultaneously moved to the base, including the 520th Fighter Squadron from Bien Hoa Air Base (A-1 Skyraider); 217th Helicopter Squadron from Tan Son Nhut Air Base (H-34 Choctaw) and the 116th Observation Squadron from Nha Trang Air Base (O-1 Bird Dog).

USAF use during the Vietnam War

United States Air Force units began using Binh Thuy as a Forward Air Control (FAC) base simultaneously with the VNAF in September 1965. Seventh Air Force activated the 632d Combat Support Group (632d CSG) which performed the non-operational base hosting mission. The 632d CSG supported transient Air Force gunships, transport aircraft, and other close air support aircraft, while the United States Navy operated a Naval Support Activity and a Naval Air base with a combat helicopter squadron (HAL-3) a few miles south of the base. The "Black Ponies, VAL-4 Naval aviation squadron of OV-10s operated from Binh Thuy. Detachment 10 of the 38th Aerospace Rescue & Recovery Squadron, US Air Force, operated two HH-43 helicopters at Binh Thuy from 15 September 1965 to 20 December 1969. One or two Y0-3As operated by the 220th Surveillance Aircraft Company, 16th Aviation Group, U.S. Army. Also some YOV-10D Broncos (2 EA) were operated from the base by the U.S. Marines 1st MAW detachment.

22d Tactical Air Support Squadron

The O-2A and Bs Super Skymasters aircraft, 1967-1971.

The squadron provided air crews in Vietnam to direct air strikes for tactical aircraft operating within the Tactical Air Control System (TACS). It also performed visual reconnaissance, convoy escort, and other missions as directed by the Tactical Air Commander. Aircraft and maintenance were provided in support of these operations within IV Corps, Republic of Vietnam, as directed by Seventh Air Force. The squadron provided aircraft and personnel in support of the Theater Indoctrination School, and field and transient maintenance support of USAF aircraft at Binh Thuy.

In 1969, the 22d TASS began closing down operations at the base as part of the general US withdrawal from South Vietnam. The squadron was moved to Bien Hoa Air Base in January 1970, with the last assigned USAF personnel leaving by the end of the month. At Bien Hoa, the assets of the 22d TASS were absorbed by the Wheeler Air Force Base, Hawaii on 15 May 1971.

Known VNAF Units At Binh Thuy

With the Americans moving out in 1969, Binh Thuy Air Base became the headquarters for the VNAF 4th Air Division. The 74th Wing was supplemented by the 84th Tactical Wing in 1972 with helicopter gunship units to further the defense of the Mekong Delta region. By 1974, the SVNAF had the following units assigned to the base:

  • 4th Air Division (Headquarters)
  • 74th Tactical Wing
116th/122d Liaison Squadron Cessna O-1A, U-17As and U-17B
520th/526th/546th Fighter Squadron A-37A/B
  • 84th Tactical Wing
211th/225th/227th Helicopter Squadron UH-1D
Det G 259th Helicopter Squadron Bell UH-1H Hueys (Medevac)

Also about 4 VNAF AC-47 gunships were assigned to the base.

Capture of Binh Thuy Air Base

By late April 1975, in the general retreat of South Vietnamese military forces south many surviving VNAF aircraft landed at Binh Thuy, Bien Hoa and Tan Son Nhut Air Bases. Sorties flown during the final days before the Fall of Saigon were to support defensive actions at Phan Rang, Phan Thiết and Xuân Lộc, however no effort was made to fly against advancing North Vietnamese columns moving south. This was due in part to the Soviet-made SA-7 shoulder held surface-to-air missiles which the VNAF had no defense against along with a lack of reconnaissance aircraft. The South Vietnamese government literally had no idea of what was happening inside the territory lost to North Vietnamese forces.

Following the last-ditch effort in defense of Saigon in the Battle of Xuân Lộc, North Vietnamese forces quickly overran Bien Hoa Air Base and moved along Highway One towards Saigon. By April 29 the fighting had reached the suburbs with North Vietnamese troops overruning Tan Son Nhut Air Base. On April 30, 1975 the South Vietnamese government surrendered unconditionally and South Vietnam ceased to exist.

Some VNAF planes and personnel managed to escape to Thailand from still-unoccupied Binh Thuy
