Phan Rang Air Base (also called Thành Sơn Air Base) is a Vietnam Air Defence - Air Force (VADAF) (Khong Quan Nhan Dan Viet Nam) military airfield in Vietnam. It is located 5.2 miles (4.5 nmi; 8.4 km) north-northwest of Phan Rang – Tháp Chàm in Khánh Hòa province.
Initially built by the Imperial Japanese Army about 1942, the airfield was also used by the French Air Force (French: Armée de l'Air) during the First Indochina War then abandoned in 1954. The United States rebuilt the airfield in 1965 and it was used by the Republic of Vietnam Air Force (RVNAF) and the United States Air Force during the Vietnam War in the II Corps Tactical Zone of South Vietnam.
It was seized by the People's Army of Vietnam (PAVN) in April 1975 and has been in use by the VADAF ever since.
The airfield at Phan Rang was used by the Japanese during World War II. In the late 1940s and early 1950s the French Air Force used the same 3,500-foot (1,100 m) runway, and abandoned the facility when French control over Indochina ended in 1954.
In April 1965 CINCPAC instructed an engineering survey for a new airfield at Phan Rang. In July 1965 it was planned that 3 fighter squadrons would be deployed to Phan Rang Air Base once it was completed in October.
In late-August 1965 the newly arrived US Army 62nd Engineer Battalion (Construction) was ordered to build a jet-capable airfield at Phan Rang. Commencing construction in September the Army Engineers built a 10,000-foot (3,000 m) AM-2 aluminum matting runway and open aircraft revetments. Bad weather and shortages of concrete, piping and aluminum matting delayed the base construction, with the completion date progressively delayed to December 1965 and then April 1966. With the movement of the 1st Brigade, 101st Airborne Division to Phan Rang to provide security for base construction, the 62nd Engineer Battalion was also required to construct a base for the 1st Brigade. While the 62nd Engineers constructed the temporary runway, American construction consortium RMK-BRJ was working on a permanent 10,000-foot (3,000 m) concrete runway, taxiways and parking areas. In January 1966 the USAF 554th RED HORSE Squadron arrived at the base to assist with construction.
The temporary aluminum runway became operational on 20 February and by mid-March all the interim facilities were operational. Heavy rain in May 1966 and rushed construction led to damage to the aluminum runway and taxiways and in June the 62nd Engineers rebuilt the taxiways while the 554th RED HORSE and RMK-BRJ rebuilt the runway, reducing its available length to 6,000-foot (1,800 m). The 62nd Engineers also built a 46,000-barrel fuel storage area, a six-inch pipeline to the beach and two 8-inch submarine pipelines from the beach to an offshore floating mooring and discharge facility. On 12 October 1966 RMK-BMJ completed the concrete runway and 4 connecting taxiways. By the end of the year the base was fully completed with powerplant, water and sewage system, operations, accommodation and other structures.
The USAF forces stationed there were under the command of the United States Pacific Air Forces (PACAF) Seventh Air Force. In addition, the United States Navy, and United States Marine Corps had aviation and other support units stationed at Phan Rang.
Due to the delays in completion of the base, the F-4C Phantom II equipped 391st Tactical Fighter Squadron was diverted from Phan Rang to Cam Ranh Air Base and the 480th Tactical Fighter Squadron went to Da Nang Air Base.
On 14 March 1966 the F-4C equipped 389th Tactical Fighter Squadron arrived at the base becoming the first USAF squadron to deploy there.
On 20 March 1966 the 366th Tactical Fighter Wing was the first permanent USAF organization to be stationed at Phan Rang Air Base. The rain damage to the base in May 1966 delayed the deployment of the 391st Tactical Fighter Squadron from Cam Ranh AB and the 480th TFS from Da Nang AB. The squadrons assigned to the 366th TFW during this period were:
The US population at the base increased dramatically from 118 in March 1966 to over 4,500 in September 1966. This increase led to pressure on accommodation and maintenance facilities which were still under construction; the growth of prostitution in the "sin strip" outside the base; and an increase in employment of Vietnamese on the base, growing to 1000 by the end of 1966.
On 10 October 1966, the 366th TFW and the 389th Tactical Fighter Squadron moved to Da Nang AB and the 35th Tactical Fighter Wing at Da Nang AB moved to Phan Rang.
On 10 October 1966 the 35th Tactical Fighter Wing took over as the host unit at Phan Rang.
Units assigned to the 35th TFW were:
Missions included air support of ground forces, interdiction, visual and armed reconnaissance, strike assessment photography, escort, close and direct air support, and rapid reaction alert. It struck enemy bases and supply caches in the Parrot's Beak just inside the Cambodian border, April–May 1970 and provided close air support and interdiction in support of South Vietnamese operations in Laos and Cambodia, January–June 1971.
The B-57 Canberra equipped 8th and 13th Bombardment Squadrons relocated to Phan Rang with the 35th TFW.
B-57 units assigned to the 35th TFWA at Phan Rang were as follows:
On 24 December 1966, 3 Operation Tropic Moon II B-57s, experimentally fitted with a low light level television system carried in a pod underneath the port wing arrived at Phan Rang.
By November 1969 the 8th Bombardment Squadron's strength was down to only 9 aircraft, and it was decided that it was time to retire the B-57B from active service. The surviving aircraft were sent back to the United States in September and October and the 8th Bombardment Squadron was moved to Bien Hoa Air Base and redesignated the 8th Special Operations Squadron.
The RAAF Canberras continued operations from Phan Rang AB until they were withdrawn in June 1971.
Detachment 1, 38th Aerospace Rescue and Recovery Squadron equipped with HH-43 Huskies relocated to the base from Nakhon Phanom Royal Thai Air Force Base.
In November 1967 Phan Rang became a forward operating location for 4 AC-47 Spooky gunships of the newly-activated 14th Air Commando Squadron.
On 31 January 1968 at the start of the Tet Offensive, naval gunfire from USS Mansfield was used to deter a VC attack on the base and gunfire from the USS New Jersey later deterred a similar attack.
On 15 April 1968 the 550-man 821st Combat Security Police Squadron was deployed to the base on temporary duty, they were replaced by the 822nd Combat Security Police Squadron in August 1968. The 822nd was replaced by the 823rd Combat Security Police Squadron in March 1969 and was then replaced by the 821st in August 1969. The 821st remained at Phan Rang until February 1971 when it was inactivated.
In mid-September 1968 the Federalized Utah National Guard 116th Engineer Combat Battalion deployed to Phan Rang Air Base to begin a ten-month tour of duty.
Between 10 August 1968 and 31 May 1969, the 554th Civil Engineering Squadron built an armament and electronics shop, fire station, a concrete access taxiway, 6 troop barracks and 2 officers quarters protecting by a revetment wall, a 49,000-square-yard asphalt hardstand, and a base theater.
Commencing in October 1968, USAF engineers built 61 "Wonderarch" aircraft shelters at Phan Rang.
On 26 January 1969 the VC attempted to attack the base. Captain Garth Wright, Security Operations Officer in the 35th Security Police Squadron was later awarded the Air Force Cross for his role in defending the base.
On 3 May 1970 VC sappers attacked the base but were repulsed with minor damage and no Allied casualties. On 10 September VC attacked the main gate but were also repulsed with little damage and no Allied casualties.
The 315th Air Commando Wing (Troop Carrier) moved to Phan Rang from Tan Son Nhut Air Base on 15 June 1967 and became a tenant unit supported by the 35th Combat Support Group.Initially designated as the 315th Air Commando Wing, it was redesignated the 315th Special Operations Wing on 1 August 1968. Squadrons assigned were:
Operations included aerial movement of troops and cargo, flare drops, aeromedical evacuation, and air-drops of critical supplies and paratroops. In 1971–1972 the unit helped to train C-123 aircrews for the RVNAF. The wing was redesignated as the 315th Tactical Airlift Wing on 1 January 1970 and was inactivated on 31 March 1972.
In 1971 the 315th TAW expanded its mission with the control of the interdiction and the psychological warfare and visual reconnaissance operations of the following counter-insurgency squadrons:
On 15 January 1972, the 8th Special Operations Squadron was reassigned to Bien Hoa AB as part of the USAF drawdown at Phan Rang. The 9th SOS was inactivated on 29 February 1972.
The 14th Special Operations Wing operated from Phan Rang from 15 October 1969, transferring operational squadrons from Nha Trang Air Base and became a tenant unit supported by the 35th Combat Support Group.
The 14th SOW's operations included close and direct air support, interdiction, unconventional warfare, counter-insurgency operations, psychological warfare (including leaflet dropping and aerial broadcasting) and flare drops. Squadrons assigned were:
Flying from Phan Rang sorties were flown over target areas consisting of the Mekong Delta and the Ho Chi Minh Trail. The aerial gunships destroyed trucks, attacked enemy encampments, ammunition dumps and other ground targets using night vision equipment. It also trained RVNAF personnel in AC-119 operations and maintenance, from February to June 1971. The first crews graduated in April 1971 and with AC-119s transferred to the RVNAF formed the 819th Combat Squadron.
The 35th TFW was inactivated on 31 July 1971 as part of the general drawdown of United States forces in South Vietnam with the wing's remaining resources passing to the 315th Tactical Airlift Wing. The 352d TFS and the 615th TFS were inactivated in place along with the 35th TFW, standing down from operations on 26 June 1971. The 612th TFS and 614th TFS were inactivated in place on 31 July 1971.
