They were prominent reasons for the success of "Shasta"s deployment. "Shasta" underwent major overhauls on the San Francisco waterfront in 1986 and 1988, including several months in dry dock in 1988. "Shasta"s home port was Concord Naval Weapons Station, on the Suisun Bay in the Sacramento River. However, "Shasta" spent much of its inport time at Mare Island Naval Shipyard on the Napa River in Vallejo, California; Naval Air Station Alameda in Alameda, California on the South San Francisco Bay; and Naval Supply Center, Oakland and Oakland Army Base, both in Oakland, California also on the South San Francisco Bay. "Shasta" also spent several months every two years at various shipyards on the south San Francisco waterfront. This situation of going to sea from one port and returning to another led to many logistical difficulties for the ship's crew. "Shasta" had a special relationship with the Benicia Yacht Club, in Benicia, California, and participated in many of its Blessing of the Fleet ceremonies in the Carquinez Strait of the Sacramento River, leading to many memorable festivities. "Shasta" also participated in Fleet Week in San Francisco Bay. "Shasta's" crew participated in community events in Shasta, California, her namesake city and near her namesake Mount Shasta, and extinct volcano in Northern California, including "Shasta's" honor guard marching in holiday parades. "Shasta" trained midshipmen from NROTC and the United States Naval Academy. Shasta also hosted "tiger cruises" for family members and Navy veterans through the Navy League. In early 1990, "Shasta" underwent a major shipyard overhaul on the San Francisco waterfront, and conducted sea trials in May 1990. Among other upgrades, the berthing compartments were upgraded to accommodate approximately 45 enlisted women. "Shasta" deployed in support of Operations Desert Storm and Desert Shield from December 1990 to June 1991. "Shasta" deployed to the Western Pacific, Indian Ocean and Persian Gulf in 1993. "Shasta" underwent shipyard overhaul, including dry dock from January through June 1994. "Shasta" also deployed to the Western Pacific, Indian Ocean and Persian Gulf from November 1995 through June 1996. This was "Shasta's" last deployment before her decommissioning transfer to Military Sealift Command. "Shasta" was decommissioned on 1 October 1997 as a "United States Ship" and transferred to the Fleet Auxiliary Force of the Military Sealift Command (MSC) as a "United States Naval Ship".
