 In 1964 and 1965, the wing's B-52Fs were selected for modification under programs South Bay and Sun Bath.These modifications enabled the wing's bombers to double their bomb load from 24 to 48 750 lb bombs by the installation of external bomb racks.With these modifications, the wing's planes, along with those of the 320th Bombardment Wing at Mather AFB, were the first to deploy to Andersen Air Force Base, Guam and the first to fly Arc Light bombing missions.
