Supporting the Edwards test flight aircraft was this temporary deployed 319th Bomb Wing/ 905th Air Refueling Squadron KC-135A, originating from Grand Forks (ND). The 905th ARS was supporting some 6512nd TS B-1B activities from Edwards. The 319th converted from B-52 to B-1B in the 1986-1987 timeframe and a lot of new-weapons tests were carried out by the 6512 TS B-1Bs. As the 905th became very experienced with B-1B aerial refueling, it was logical to deploy one of their Lancers to Edwards that lacked KC-135As in their fleet.
