The wing placed aircraft on peacetime quick reaction alert duty, and conducted global bombardment training for Emergency War Order operations and air refueling operations to meet SAC commitments. During the Vietnam War, the 319th Bomb Wing's mission expanded to include sending bomber and tanker aircrews on temporary duty assignments to support B-52 and KC-135 operations from 1963 to 1974. Tanker crews participated in refueling operations for both bombers and fighters. The bomb crews flew B-52Ds from bases at Andersen AFB, Guam; Kadena AB, Okinawa, and U-Tapao RTNAF, Thailand. Bomber crews participated in Operation Arc Light in 1968 and Operations Linebacker I and Linebacker II in 1972.
