On 19th January 1961, PACAF had identified 25 airfields, 49 lines of communication routes and 19 urban targets. A few weeks later, HQ USAF authorized the release of these photographs to the governments of Laos and Thailand.

On 23rd March 1961 Pathet Lao Anti-aircraft Artillery opened fire on an American C-47 as it flew over the eastern portion of the Plaines des Jarres, shooting the plane down. It was one of the first USAF aircraft shot down over Indochina, and marked the beginning of combat action by the USAF from bases in Thailand.

Origins of U.S. military presence in Thailand

The official American military presence in Thailand started in April 1961 when an advance 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.

These small detachments received logistical support from their home bases outside of Southeast Asia. Circumstances in the region, however, were leading to drastic changes in the US position. On 29 April 1961, the Joint Chiefs of Staff instructed CINCPAC to move 5,000 troops and air elements to both Udon Air Base

On 23 July 1962 fourteen nations signed the Geneva Accords of 1962 which contained the following provisions:
  • Laos was to become politically neutral and not enter into any military alliance.
  • Laos would not allow foreign military forces to use or occupy its territory.
  • Laos would not recognize any military alliance or coalition, such as SEATO.
  • Laos would not allow any foreign interference in its internal affairs.
  • All foreign troops, paramilitary forces and foreign military personnel would be removed from Laos in the "shortest possible time".


The treaty was signed the Soviet Union, South Vietnam, China, North Vietnam and the United States, among others. But North Vietnam continued moving heavy weapons into Laos to support the communist rebel Pathet Lao. Of the 10,000 North Vietnamese troops in Laos at the time of the agreement, 6,000 remained in the country in violation of the accords.

In spite of the agreement, fighting continued in Laos, with North Vietnamese troops hidden in Pathet Lao-held areas. Near the end of August a USAF RF-101 reconnaissance aircraft was fired on by radar-guided Anti-aircraft warfare

By October 1963, President Kennedy realized the situation was untenable and decided on a withdrawal of all US forces, beginning with the announcement of 1000 soldiers being returned home by Christmas.

The day after his death, President Johnson reversed that decision and immediately sent more troops. The buildup had begun.

Gulf of Tonkin Incident

By mid-1964, the situation in Southeast Asia was ambiguous. Communist forces were making military and political gains. The United States seemed to be assuming the French role and fear was increasing that Communism would prevail over the pro-U.S. governments in the region.

The "Secret War" in Laos

Thailand was a member of SEATO. While supposedly maintaining an air of neutrality, it was deeply concerned about the fighting in neighboring Indochina
Indochina

The name has its origins in the French, Indochine, as a combination of the names of "China" and "India", and was adopted when French colonizers in Vietnam began expanding their territory...

. Over the centuries, Thai governments had managed to avoid foreign domination with a policy of accommodation with the predominant power in Asia at the time. By 1965, the increasing amount of American aircraft deployments to Thailand was jeopardizing policy.

The Royal Thai government's desire to avoid publicity led to the formation of a policy to downplay the United States' presence and not draw attention to its tactical air units in Thailand. This is why so little information about the USAF in Thailand was made public during the Vietnam War. Much of that information remains unavailable, being considered sensitive to the Thai government. The Thai government prohibited photographing of American personnel and military aircraft, with the exception of official archive photography taken for documentation and official release.

, were prohibited from filing stories about American military activities. Attacks on US bases and personnel were suppressed and any personnel wounded during military action in Thailand did not receive recognition of or awards for their wounds. Military information officers were instructed that no mention was to be made of operations from Thai facilities, no names of bases were to be mentioned and no mention of operational activities were to be released. The report "Snakes in the Eagles Nest" gives a partial account of combat operations in Thailand during the Vietnam War.

Although the existence of the so-called "Secret War" was sometimes reported in the U.S., details were largely unavailable due to official government denials that the war even existed. The denials were seen as necessary considering that the US had signed agreements specifying the neutrality of Laos. US involvement in Laos was considered necessary because North Vietnam had effectively conquered a large part of the country and was equally lying in public about its role in Laos.

Despite these denials, however, the Secret War was actually the largest U.S. covert operation

USAF withdrawal from Thailand

The United States ended its involvement in Southeast Asia by treaty and disengagement rather than by military victory. After the fall of Saigon in 1975, relations between Washington and Bangkok turned sour. In May 1975, the Royal Thai Government asked the United States to remove all of its combat forces (27,000 troops, 300 aircraft) by 1976.

The USAF bases were closed and the last USAF personnel left Thailand in June 1976.

The removal of U.S.Military forces was accomplished by United States Marine Detachment BLT 1/9 out of Okinawa, Japan.
