Vincent AFB was transferred to the Navy on 1 Jan 1959, and the tenant radar site was renamed Yuma Air Force Station. On 20 July 1962, the base designation was changed to Marine Corps Air Station. In this time frame, the Air Force began construction of a new Yuma AFS (RSM-162) about 13 miles south of Yuma. However, the replacement site was never completed, as, in March 1963, the Air Force ordered the 864th AC&W Squadron to inactivate. Operations ceased 1 August 1963.
