Subsequent to a leave and upkeep period, "Berkeley" entered the Long Beach Naval Shipyard for a restricted availability on 19 July. During that yard period, workers installed the new Standard missile system, including launch rails and guidance equipment. Upon leaving the shipyard on 25 August, the warship commenced a three-month missile development test and evaluation program. This entailed weekly cruises in southern California waters and the firing of Standard missiles at air and surface targets. Following the removal of test equipment in mid-December, the guided missile destroyer spent the rest of the month getting ready for upcoming fleet exercises.
