It was assigned the Boeing KC-135A Stratotanker in January 1957, making it the first SAC bomb wing to receive the new aircraft. In June 1958, the wing received six B-52Fs, making it the first to fly this series of the Stratofortress. Throughout the height of the Vietnam War (1968–1974) the wing operated a special B-52 aircrew replacement training unit to support SAC's B-52 operations in Southeast Asia. The wing recorded another first on 10 June 1982 when the first all female KC-135 crew, "Fair Force One", flew a five-hour training sortie.
