USAF Use During The Vietnam War

Roundel of the USAF.svg

During the early years of the Vietnam War (1961–1966), Don Muang was used as a major command and logistics hub of the United States Air Force. The USAF forces at Don Muang were under the command of the United States Pacific Air Forces (PACAF) Thirteenth Air Force.

After the expansion of U-Tapao Royal Thai Navy Airfield in 1966, most American units and personnel were transferred from Don Muang, however a small USAF liaison office remained at the base until 1975. The APO for Don Muang was APO San Francisco, 96303

USAF Advisory Units

6010th Tactical Group

The official American military presence in Thailand started in April 1961 when an advanced party of the USAF 6010th Tactical (TAC) Group arrived at Don Muang at the request of the Royal Thai government to establish an aircraft warning system.

Also in April 1961, a small detachment of F-102 "Delta Daggers" from the 509th Fighter-Interceptor Squadron, based at Clark AB, Philippines were sent to Don Muang under Operation Bell Tone. Their mission was to bolster the defense capabilities of the Royal Thai Air Force. For the next several years, a minimum of four F-102 interceptors were kept on alert at Don Muang.

Then in November 1961, four RF-101C reconnaissance aircraft of the 45th Tactical Reconnaissance Squadron stationed at Misawa AB, Japan and their photo lab arrived at Don Muang. The RF-101s were sent to assist Royal Thai AF RT-33 aircraft in performing aerial recon flights over Laos the RF-101s stayed until May 1962, then returned for a second deployment during November and December 1962. In August 1962 elements of the 15th Tactical Reconnaissance Squadron stationed at Kadena AB, Okinawa were deployed to Don Muang flying RF-101C's.

Two milestones occurred early in 1962. The Military Assistance Group in South Vietnam was renamed U.S. Military Assistance Command, Vietnam (MACV) on 6 February. The other being a joint communication from Secretary of State Dean Rusk and Thai Foreign Minister Thanat Koman on 6 March in which the United States "firm intention... to aid Thailand, its ally and historic friend in resisting communist aggression and subversion". As a result, the Military Assistance Command, Thailand (MACT) was set up on 15 May 1962 at Don Muang.

35th Tactical Group

In November 1962 the 2nd Air Division assumed control of the 6010th TAC Group. In August the group was re-designated the 35th Tactical Group. The 35th TAC group consisted of the following units:

  • 35th Air Base Squadron - Located at Don Muang.
  • 331st Air Base Squadron - Located at Takhli RTAFB.
  • 332nd Air Base Squadron - Located at Ubon RTAFB.
  • Det #1, 35th Tactical Group - Located at Korat RTAFB.

By mid-1964 the situation in Southeast Asia was ambiguous. North Vietnam was determined to take over South Vietnam. Communist rebel forces were making military and political gains in Laos. The United States was taking over the role of "protector" from France in the area and the fear was that Communism would prevail over the democratic governments in the region. However there was no real justification for a full-scale American military involvement in the region.

On 31 July 1964 the Gulf of Tonkin Incident occurred. It was a pair of alleged attacks by North Vietnamese gunboats on two American destroyers, the USS Maddox and the USS C. Turner Joy, off the North Vietnamese coast in the Gulf of Tonkin. As a result, President Johnson would order more forces to support the west-allied South Vietnam government, and additional USAF forces were dispatched to Thailand, beginning a large scale United States military presence in Southeast Asia.

631st Combat Support Group

In July 1965 the 35th TAC Group was re-designated the 6236th Combat Support Group and again in April 1966 it was re-designated the 631st Combat Support Group. In March 1965 there were 1342 enlisted men stationed at Don Muang RTAFB, with their primary mission to provide support for all USAF units and detachments assigned to the base or other bases in Thailand.

Units assigned to Don Muang RTAFB were the following:

  • Host Unit - 631st Combat Support Group - 2 C-47s
    • Det #4 315th Air Division - 7 C-130Es
    • 509th Fighter Interceptor Squadron - 5 F-102s
    • 452nd Air Refueling Squadron - 4 KC-135s

F-102's were primarily interceptors assigned to the Air Defense Command in the United States, however it was over the skies of Southeast Asia that the F-102 was to achieve its only taste of combat. Aircraft from the 509th Fighter Interceptor Squadron, based at Clark Air Force Base were sent on Temporary Duty (TDY) to Don Muang in March 1962 to provide air defense against the unlikely event that North Vietnamese aircraft would attack Thailand.

TDY F-102As from 509th also stood alert at Tan Son Nhut Air Base, Bien Hoa AB and Da Nang AB in South Vietnam and at Udon RTAFB in Thailand.

The F-102A was finally withdrawn from Southeast Asia in December 1969. The F-102A established an excellent safety record with almost ten years of flying air defense and a few combat air patrols for SAC B-52s, only 15 F-102As were lost.

Although a few missions were flown over North Vietnam, the Southeast Asia-stationed F-102As are not thought to have actually engaged in air-to-air combat, although one of F-102A of the 509th FIS was lost to an air-to-air missile fired by a MiG-21 while flying a CAP over Route Package IV on 3 February 1968.

Two F-102As were lost to AAA/small arms fire and four were destroyed on the ground by the Viet Cong and eight were lost in operational accidents.

USAF withdrawal from Don Muang

By 1966 the USAF and Thai Air Force had established a major presence in Thailand, with the Americans operating out of six Royal Thai Air Bases. At Don Muang the USAF had stationed KC-135 air refueling tankers from Strategic Air Command (SAC) for refueling tactical combat aircraft over the skies of Indochina. Thailand was officially neutral in the Vietnam War and the visibility of the large USAF Boeing tankers in its capital was causing political embarrassment to the Thai government.

The USAF 7th Air Force in Saigon wanted to have additional KC-135's in Thailand and the solution reached was to expand the Naval airfield at U-Tapao Royal Thai Navy Airfield and base the tankers there. Expansion of U-Tapao began in October 1965, with the completed new facility opening at the end of 1967. The 11,000-foot (3,400 m) runway became operational on 6 July 1966. U-Tapao received its first complement of USAF Strategic Air Command (SAC) KC-135 tankers in August 1966. By September, the base was supporting 15 tankers.

The opening of U-Tapao also allowed the United States to route most of its logistics requirements in Thailand to be routed through that facility rather than having large cargo aircraft arrive in the Thai capital.

By 1970 most USAF operations had moved out of Don Muang, however administrative personnel coordinating activities along with Military Assistance Command, Thailand (MACT) staff were assigned to the base until 1975.
