The USS Mount Vernon (LSD-39) was an Anchorage-class dock landing ship commissioned into the United States Navy in 1972. Built by the General Dynamics Quincy Shipbuilding Division in Quincy, Massachusetts, she featured the distinctive design of the Anchorage class, combining a well-deck with a flight deck to facilitate amphibious operations involving landing craft, helicopters, and other small vessels. The ship's well-deck allowed for the deployment of Landing Craft Air Cushion (LCAC), and she was notably the first West Coast ship to be modified for LCAC support, enhancing her amphibious capabilities. Mount Vernon served primarily in the Pacific and Far East regions, completing 15 deployments with the U.S. Seventh Fleet over her 31-year career. Her operational history included participation in significant missions such as Operation Frequent Wind in April 1975, the evacuation of Saigon during the Vietnam War. She also contributed to maritime security and logistical support during the Exxon Valdez oil spill cleanup in 1989, acting as a floating hotel and command platform for shoreline cleanup workers in Prince William Sound. During this operation, she provided essential services such as medical aid, housing, communication support, and helicopter operations, playing a vital role in the environmental disaster response. Throughout her service, USS Mount Vernon was homeported in San Diego, California, and Long Beach, California, before being decommissioned on 25 July 2003. Her distinguished career earned her numerous awards, and she made a historic mark on the Navy by being commanded by Commander Maureen A. Farren in 1998, the first American woman to command a U.S. Navy surface warship. After decommissioning, the vessel remained at Pearl Harbor before being intentionally sunk in 2005 off the coast of Hawaii during a training exercise called "Patrolling Thunder." Her sinking involved the use of various munitions, including Harpoon and Maverick missiles and 500-pound bombs. The USS Mount Vernon remains a notable example of the amphibious ship design and operational versatility within the U.S. Navy.
