U-Tapao RTNAB was a forward operating base for B-52 Stratofortresses and KC-135 Stratotankers of the Strategic Air Command (SAC). Providing base and logistic support for those long-range bombers and tankers was the 635th Combat Support Group (PACAF), while the flying activities and operations of these aircraft were controlled by the 307th Strategic Wing (SAC). The 307th Strategic Wing was the largest associate unit on base, and it had its own headquarters, avionics, field, munitions and organizational maintenance squadrons. The base supported the 1985th Communications Squadron, the 11th USAF Hospital, Det. 12, 38th Aerospace Rescue and Recovery Squadron, Det. VP-46, 72.6 U.S. Naval Task Group and a Fleet Air Support Unit. Ten other detachments and operating units provided on-base support for the U S. Air Force mission at U-Tapao.

  • History of the United States Air Force at U-Tapao RTNAB

    U-Tapao RTNAB was home of the 635th Combat Support Group (CSG), the newest of seven key installations which housed United States Air Force personnel in Thailand. Originally designed to support an aerial refueling mission and troop transport squadron, the mission was amended to include support for Strategic Air Command B-52 bombers in their daily strikes against enemy targets in Southeast Asia.

    Beginning construction in October 1965, the airfield was considered one of the finest in Southeast Asia slightly more than two years later. First on the airfield construction priorities were the aerodrome facilities, including an 11,000-foot runway, which became serviceable on 6 July 1966. On this date, the first landings were made at U-Tapao; first came a Royal Thai Air Force HH-16, then a USAF C-130. Steadily progressing and adding to the mission, U-Tapao welcomed its first complement of KC-135 tankers in August 1966. In September, the base was supporting 15 tankers.

    One of the most significant mission changes in the history of the Air Force came about when the Department of Defense chose U-Tapao as a staging base for the SAC B-52 bombers, the giant eight-engine bomber backbone of the USAF. Official approval to use U-Tapao as a B-52 base camp came just three months before the bombers began operations in Thailand. This caused an already tremendous work load to approach the endurability limits of both men and machines, but, in true Air Force fashion, hardships were overcome, progress was made, and all efforts culminated on 10 April 1967, when three B-52 bombers landed at U-Tapao following a bombing mission over Vietnam. The very next day, B-52 operations were initiated at U-Tapao.

    The 4258th Strategic Wing (SAC) was activated in June 1966 at U-Tapao under 3rd Air Division, Andersen AFB, Guam. The wing was charged with the responsibility of supporting refueling requirements of USAF fighter aircraft in Southeast Asia, plus conducting bombing missions on a daily basis.

    On 21 January 1970, in conjunction with the redesignation of the 3rd Air Division, Andersen AFB, Guam, as the Eighth Air Force, the 4258th SW was redesignated as the 307th SW.

    On 1 June 1972 the 307th SW was reorganized into the 17th Air Division (Provisional), the 310th SW (Provisional) and the 307th SW. U-Tapao Stratofortress force was under the control of the 307th wing, while the, KC-135 tanker force is under the 310th wing. Both wings were under the command of the 17th Air Division. Other missions of the U-Tapao organization included supplying other U.S. occupied Thai installations with equipment and material; support of the U.S. Army, Navy and Coast Guard units in the area; and jurisdiction for what became known as the Sattahip complex. This complex included a nine-berth deep water port, a Coast Guard LORAN station, three U.S. transportation units, and approximately 10,000 American servicemen and Thai nationals who worked and resided in the surrounding hamlets and towns.

    Facilities located on U-Tapao included airmen dormitories and officer BOQs for housing of more than 7,000 airfield personnel, three recreation clubs, a beach facility, library, a base exchange, swimming pool, base theater, chapel and hobby shops.

    Air Campaigns Flown Out Of U-Tapao

    Operation Arc Light, 18 June 1965 - 15 August 1973

    Arc Light was the name given to the SAC B-52 conventional bombing missions in Southeast Asia during the Vietnam War. The first Arc Light mission was flown 18 June 1965 when Guam-based B-52s were used to attack a Viet Cong jungle stronghold with conventional 750-pound and 1,000-pound bombs. B-52s were used primarily in saturation bombing of Viet Cong base areas, but also were used in direct tactical support of operations such as the Marine Corps’ Operation Harvest Moon and the First Cavalry Division’s fight in the Ia Drang Valley. In 1966, operations were mostly against targets in S. Vietnam, but expanded to include approaches to the Mu Gia Pass in North Vietnam on 12 and 26 April 1966, to interdict the northern Ho Chi Minh Trail. Bombing activity increased tremendously in 1967, almost doubling the number of sorties flown in 1966, supporting ground troops and attacking enemy troop concentrations and supply lines in the A Shau Valley.

    The 1968 defense of Khe Sanh was the largest and most significant air campaign to date in Southeast Asia, helping to break the siege on Khe Sanh and force the North Vietnamese to withdraw. In 1969, the B-52 conventional bombing operations in Southeast Asia continued at a steady pace with greater emphasis on harassment and disruption of enemy operations than in previous years, particularly around Saigon. SAC bombers also continued to hit enemy supply dumps, base areas, troop concentrations, and the Ho Chi Minh Trail in Laos. The number of sorties flown in support of Arc Light bombing operations declined from November 1969 until ceasing temporarily in August 1970.

    Guam-based B-52s resumed flying in February 1972, in a surge of Arc Light activity named Bullet Shot, reaching a peak by mid-1972 exceeding all previous records of Arc Light performance as the U.S. pushed the Communist forces hard to force peace negotiations. After the Paris Peace Accords ended U.S. involvement in Vietnam in January 1973, Arc Light operations continued in Laos and Cambodia, until the end of U.S. combat operations on 15 August 1973.

    The Arc Light Memorial at Andersen Air Force Base, Guam, is dedicated to the 75 men who lost their lives flying Arc Light B-52 missions.

    Operation Menu, 18 March 1969 - 26 May 1970

    Menu was directed at Cambodian base areas and logistics networks supporting Communist operations in South Vietnam. President Nixon ordered these raids to punish Hanoi for their continued fomenting of fighting in South Vietnam while they simultaneously avoided serious peace negotiations and to gain time for Vietnamization to prepare S. Vietnam's forces. Anti-war protests in the U.S. limited President Nixon's options since further bombing of North Vietnam would be politically unacceptable, so the Cambodian sanctuaries were targeted.

    During the Menu series of raids, B-52s flew 3,630 sorties and dropped 100,000 tons of bombs. Individual missions in the Menu series were named Breakfast, Supper, Lunch, Dessert, and Snack, thus the name Menu bombing. Menu raids continued until 26 May 1970, when the bombing campaign was exposed by the New York Times after the start of the Cambodian Incursion by ground troops.

    While the Arc Light raids were open and authorized through channels, Menu missions were not. The classified missions were directed by the White House and personnel involved had to deceive USAF officials and falsify official records. Knowledge of the operations was highly compartmentalized; even the Air Force Chief of Staff and the SEC-AF were not informed. Arc Light raids were used to cover the Menu raids. Formations were sent together, sometimes in the same groups, sometimes at the same time. While Arc Light groups hit southern targets, Menu groups crossed the border into Cambodian air-space. Menu pilots later falsified reports, stating they had bombed South Vietnam.

    Operation Linebacker, 6 April 1972 - 23 October 1972

    Operation Linebacker, the aerial interdiction campaign against North Vietnam which began on 6 April 1972 with attacks in the southern part of the country expanded rapidly. On 16 April, B-52s, escorted by fighter and aircraft specializing in electronic countermeasures and suppression of surface-to-air missiles, bombed the fuel storage tanks at Haiphong, setting fires that, reflected from cloud and smoke, were visible from 110 miles away. Shortly afterward, carrier aircraft joined Air Force fighter-bombers in battering a tank farm and a warehouse complex on the outskirts of Hanoi. When these attacks failed to slow the offensive, naval aircraft began mining the harbors on 8 May, and two days later the administration extended the aerial interdiction campaign, formerly known as Freedom Train but now designated Linebacker, throughout all of North Vietnam.

    In terms of tactics employed and results obtained, Linebacker was a vast improvement over Rolling Thunder. During Linebacker, American aircraft attacked targets like airfields, power plants, and radio stations which disrupted the flow of supplies and reinforcements to the units fighting in the South. Laser-guided bombs proved effective, especially against bridges, severing the bridge at Thanh Hoa, which had survived Rolling Thunder, and the highway and railroad bridges over the Red River at Hanoi. However, the enemy made use of alternate methods of crossing the streams, usually traveling at night on ferries or movable pontoon bridges. Electronic jamming as in Rolling Thunder confused the radars controlling the surface-to-air missiles and antiaircraft guns. North Vietnamese MiGs gave battle throughout Linebacker but they failed to gain control of the sky, in part because American radar detected enemy interceptors rising from runways, enabling controllers to direct Air Force F-4s and Navy fighters against them.

    Nixon’s use of air power to disrupt supply lines and kill the enemy on the battlefield stopped the offensive and helped drive the enemy back a short distance without a reintroduction of the ground forces he had withdrawn from the South. In fact, the last combat troops of the U.S. Army departed in August 1972 while the South Vietnamese were counterattacking. Only 43,000 American airmen and support personnel remained. Yet the very success of the American aerial campaign caused misgivings in Saigon, where the South Vietnamese armed forces dependence on the Americans troubled President Thieu. When Thieu's commanders failed during a recent offensive, the advisers took over, bringing to bear a volume of firepower that the South Vietnamese forces themselves could not generate. Thieu realized the Americans' unilateral departure would leave South Vietnam at the mercy of the North Vietnamese forces still in his country. He balked at accepting what had come to be called a cease-fire in place, and the North Vietnamese also seemed uninterested in a settlement. President Nixon sought to remove first one and then the other obstacle to peace. He obtained Thieu’s reluctant assent to an in-place arrangement by offering "absolute assurance" that he intended to take "swift and severe retaliatory action" if North Vietnam should violate the terms of the agreement. He sought to remove the other roadblock, the stubborn attitude of the government in Hanoi, by ordering a resumption of the bombing of the heartland of North Vietnam.

    Operation Linebacker II, 18 December 1972 - 29 December 1972

    Operation Linebacker II operations were initiated on 18 December 1972 and were directed by the Joint Chiefs of Staff (JCS) to continue until further notice. The primary objective of the bombing operation would be to force the North Vietnamese government to enter into purposeful negotiations concerning a cease-fire agreement. The operation employed air power to its maximum capabilities in an attempt to destroy all major target complexes such as radio stations, railroads, power plants, and airfields located in the Hanoi and Haiphong areas. Unlike previous bombing campaigns, Linebacker II provided the Air Force and U.S. Naval forces with specific objectives and removed many of the restrictions that had previously caused frustration within the Pentagon.

    During these operations, Air Force and Navy tactical aircraft and B-52s commenced an around-the-clock bombardment of the North Vietnamese heartland. The B-52s struck Hanoi and Haiphong during hours of darkness with F-111s and Navy tactical aircraft providing diversionary/suppression strikes on airfields and surface-to-air missile sites. Daylight operations were primarily carried out by A-7s and F-4s bombing visually or with long-range navigation (LORAN) techniques, depending upon the weather over the targets. In addition, escort aircraft such as the Air Force EB-66s and Navy EA-6s broadcast electronic jamming signals to confuse the radar-controlled defenses of the North. The Strategic Air Command also provided KC-135s to support the in-flight refueling requirements of the various aircraft participating in Linebacker II operations. The impact of the bombing was obvious in the severe damage to the North Vietnamese logistic and war-support capability. By 29 December 1972, the 700 nighttime sorties flown by B-52s and 650 daytime strikes by fighter and attack aircraft persuaded the North Vietnamese government to return to the conference table.

    The United States paid a price for the accomplishments of Linebacker II. During bombing raids, U.S. Air Force and U.S. Navy aircraft encountered intense enemy defensive actions that resulted in the loss of twenty-six aircraft in the twelve-day period. Air Force losses included fifteen B-52s, two F-4s, two F-111s, and one HH-53 search and rescue helicopter. Navy losses included two A-7s, two A-6s, one RA-5, and one F-4. Seventeen of these losses were attributed to SA-2 missiles, three to daytime MiG attacks, three to antiaircraft artillery, and three to unknown causes.

    My Tour of Duty

    My tour at U-Tapao began on 15 August 1969 where I was initially assigned to the 4258th Munitions Maintenance Squadron (MMS), Aerospace Ground Equipment (AGE) Branch. When the 4258th Strategic Wing was redesignated the 307th Strategic Wing on 21 January 1970, I was reassigned to the 307th Field Maintenance Squadron (FMS), AGE Branch. My primary AFSC and rank while there was 42153, Aerospace Ground Equipement Repairman and Sergeant, E-4 respectively. Basically, anything painted yellow and powered or towed is AGE. I was fortunate to have worked on both the bomber side in the munitions storage area commonly known as the "bomb dump" and the tanker side on the flight line. My tour ended on 17 August 1970, the date of The Security Briefing. NOW THEY TELL ME! For a more complete disclosure of my experiences at U-Tapao, see: U-Tapao War Stories, a compilation of stories, tales, exaggerations, fibs and outright lies regarding my tour of duty. I am proud of my service at U-Tapao, the experiences and comradery will never be forgotten! My hope is to rekindle the memories for you U-T veterans and to provide a glimpse of what it was like for everyone else. Thanks for visiting!
