USS San Diego (LPD-22) is a San Antonio-class amphibious transport dock constructed for the United States Navy. As the fourth vessel to bear the name, she symbolizes San Diego, California’s significant naval heritage and strategic importance within the Pacific Fleet. The ship's keel was laid on May 23, 2007, at Northrop Grumman's Ingalls shipyard in Pascagoula, Mississippi. She was launched on May 7, 2010, and christened on June 12, 2010, with Linda Winter, wife of former Navy Secretary Donald C. Winter, serving as sponsor. The USS San Diego underwent extensive builder's trials, completed on November 17, 2011, which included testing her defensive systems, communications, propulsion, and auxiliary systems. Following these successful trials, she was delivered to the Navy on December 19, 2011. She departed Pascagoula on March 15, 2012, arriving at Naval Station Guantanamo Bay on March 19 for a brief layover en route to her home port of San Diego. She transited the Panama Canal on March 25 and arrived in her namesake city on April 6, 2012. The vessel was officially commissioned on May 19, 2012, during a ceremony at the Navy Pier in San Diego. As a modern amphibious transport dock, USS San Diego is designed to project U.S. military power, support Marine Corps operations, and serve as a platform for amphibious assaults, disaster relief, and maritime security operations. She has operated with the Makin Island Amphibious Ready Group and has played a role in regional security efforts, notably within the U.S. Fifth Fleet area. In 2020, the ship was involved in COVID-19 response activities, with reports of sailors testing positive during the ongoing pandemic. The vessel’s operational history highlights her role as a versatile and vital component of the U.S. Navy’s amphibious warfare and maritime presence, supporting national defense and regional stability.
