the 3960th SW was discontinued and replaced by the 43rd Bomb Wing, which became the 43rd Strategic Wing. In July, it also assumed resources and mission of the Bombardment Wing, Provisional, 4133rd, which had operational control over B-52s striking targets in Southeast Asia. The 43rd employed attached aircraft and aircrews of other SAC units that were deployed from bases in the United States to participate in Operation Arc Light combat missions in Southeast Asia from 1 July to mid-August 1970, and again from February 1972 to August 1973. Following the end of combat operations, the 43rd provided routing training and ground alert with B-52 and KC-135 aircraft, the latter provided by other SAC units on loan. During 1975 the wing provided logistical and medical support to thousands of Vietnamese refugees evacuated from their homeland and located temporarily at Guam awaiting resettlement in the United States. The wing trained to remain proficient in long-range nuclear bombing and conventional warfare capabilities. Beginning in 1974 it controlled Temporary Duty (TDY) tankers and crews participating in the Pacific (formerly Andersen) Tanker Task Force that supported SAC operations in the western Pacific Ocean. In July 1986 the 43rd activated the 65th Strategic Squadron to control the TDY air refueling forces. Since 1990 Since 1990 the 43rd has been inactivated, redesignated and activated on several occasions. In 1989 Andersen AFB was transferred from the Strategic Air Command to Pacific Air Forces. The PACAF 633rd Air Base Wing was activated on 1 October 1989, which led to the inactivation of the 43rd Bombardment Wing on 30 September 1990. The wing was redesignated as the 43rd Air Refueling Wing, and activated, on 1 June 1992 at Malmstrom Air Force Base, Montana where it conducted refueling operations under Air Combat Command (ACC) before being moved to MacDill Air Force Base, Florida when flight operations ended at Malmstrom. At MacDill it was redesignated as a group (43rd Air Refueling Group) and operated until 1 October 1996 when it was inactivated and replaced by the 6th Air Refueling Wing when Air Mobility Command assumed the air-refueling mission from ACC. It was brought back into active service in 1997 when the unit was redesignated as the 43rd Airlift Wing on 31 March and activated on 1 April 1997 at Pope Air Force Base, North Carolina under Air Mobility Command.
