At Barksdale, 2 BW supported Second Air Force's post-attack command and control system from April 1963 until March 1970. It conducted bombardment training and air refueling operations from April 1963 except for periods when all aircraft and crews were on loan to SAC organizations involved in combat operations in Southeast Asia. It began supporting SAC operations in Southeast Asia with aircraft and personnel in 1965, and increasingly supported these operations in 1966 and 1967. On 15 April 1968, gained a second B-52 and a second KC-135 squadron, again becoming a SAC "super" wing. From late May 1972 until 26 October 1973, it loaned all wing B-52 resources to SAC organizations in the Far East and Southeast Asia. From May 1972 to early November 1972 the wing loaned all but four of the wing's KC-135s and a few aircrews to other SAC units. After the return of combat resources, the wing continued supporting SAC operations in Southeast Asia into 1975, on a reduced scale.
