The first five Victors deployed to Ascension on 18 April. They were followed by four more the following day. Another six more deployed by the end of the month, bringing the Victor tanker force to fourteen, since one had returned to Marham on 26 April. Each was refuelled by another Victor before leaving UK airspace. While the Victors deployed to Ascension, their normal refuelling mission in the air was undertaken by United States Air Force Boeing KC-135 Stratotankers. The station commander at Marham, Group Captain J. S. B. Price, became the senior RAF officer at Ascension. Wing Commander D. W. Maurice-Jones assumed command of the Victor detachment at Ascension until 22 April, when he was relieved by Wing Commander A. W. Bowman, the commander of No. 57 Squadron.
