Following six weeks of contingency operations, "Berkeley" began her long transit home on 24 January 1980, arriving in San Diego via Subic Bay and Pearl Harbor on 19 February. Later that spring, the warship conducted several gunfire and missile-firing exercises before beginning a restricted availability at Long Beach on 5 May. During the ensuing six weeks, "Berkeley" received extensive engineering work, including some new boiler tubes, and equipment upgrades to her weapons and operations departments. The guided missile destroyer then spent the rest of the year conducting engineering tests and working out her new combat systems in air and surface gunnery and missile shoots.
