Phu Cat Air Base
Phu Cat Air Base was constructed by the RED HORSE civil engineering squadrons of the USAF. On 16 February 1966, during the initial survey to locate a new air base on the coastal plains of central Vietnam, Lt Col William H. Bordner, a USAF civil engineer officer, was killed when he triggered a phosphorus mine on Hill 151, an elevation rising out of the plain a kilometer west of the future airbase site. The main thoroughfare of the base site was named "Bordner Boulevard", and Hill 151 became unofficially known as "Bordner Hill".
The site for the new air base was selected in March and designated Base X. In April, troops of the Republic of Korea Army's Capital ("Tiger") Division cleared the base area of Viet Cong forces. On 1 May, a Korean subcontractor of the RMK-BRJ construction consortium (Raymond International, Morrison-Knudson; Brown and Root; J.A. Jones Construction), arrived to build a camp for contractors and ROK security units. By 1 June, a temporary 3000-foot dirt airstrip and a few barracks were completed. Construction of roads, utilities, the airfield complex, bomb dump, and control tower continued until the northeast monsoon temporarily halted work in September.
The RED HORSE contingent constructed a camp for the 819th CES (Heavy Repair), tasked to build the base but still training at Forbes Air Force Base, Kansas. A 55-man advance party from the 819th CES arrived directly from the United States on 6 August, followed by the entire squadron a month later, and began construction of all vertical structures on the base.
On 20 December 1966, concrete pouring commenced on the main runway; although several records were set for the most concrete poured in a single day in Vietnam, the runway did not open for operations until May 1967, and temporary runway remained in use until August. By October, all military personnel were living in permanent structures. During January 1967, as construction of the main runway, taxiways, barracks, and other infrastructure progressed, more Air Force personnel and units arrived.
With its opening in 1967, Phu Cat became a major operational base. The USAF forces stationed there were under the command of the Seventh Air Force, United States Pacific Air Forces (PACAF).
Phu Cat was notable as the testing ground for Operation Safe Side, an Air Force initiative to defend its own installations by restructuring its air base defense forces. During construction, internal base security was provided by the severely understrength 37th APS, then having only 240 APs assigned and forced to augment its ranks with 100 non-security airmen from the 37th Combat Support Group and 162 from the 819th CES. The 1041st Security Police Squadron (Test), an experimental infantry-type air police unit, was deployed to Phu Cat in the first half of 1967 to increase ground defense security.
With the inactivation of the 12th Tactical Fighter Wing, the 6259th Air Base Squadron and 6259th USAF Dispensary were activated at Phu Cat AB on 18 November 1971 to administrate services provided to the Air Force personnel remaining at the base.
The 537th TAS was inactivated at Phu Cat AB on 31 August 1971 and its C-7 aircraft were transferred to the South Vietnamese Air Force (VNAF). A number of former 537th TAS C-7 crews remained at Phu Cat AB after 1 September 1971 as instructors to the organizing VNAF 429th Transport Squadron (TS), activated at Phu Cat AB on 1 March 1972.
Phu Cat AB was officially turned over to the VNAF on 1 January 1972. A number of US Air Force instructors were relocated to Phu Cat AB to train VNAF A-37 Dragonfly light attack units.
The 6259th ABS was inactivated in February 1973 after the signing of the Paris Peace Accords.
