USS Columbus (SSN-762) is a Los Angeles-class nuclear powered fast attack submarine and the second ship of the United States Navy to be named for Columbus, Ohio. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 21 March 1986 and her keel was laid down on 9 January 1991. She was launched on 1 August 1992 sponsored by Mrs. Margaret DeMars, and commissioned on 24 July 1993.
Columbus completed a Post Shipyard Availability in June 1994 in Groton, Connecticut after initial construction and shakedown operations. In September 1994, the ship conducted an interfleet transfer to Pearl Harbor, Hawaii and joined the U.S. Pacific Fleet Submarine Force. Columbus deployed to the Western Pacific in late 1995 through early 1996 and conducted a variety of operations as a unit of the Seventh Fleet along the way making port visits in Hong Kong, Subic Bay, Guam, and Yokosuka, Japan.
Columbus was the first Submarine equipped with the BYG-1 Fire Control System in December 2002. Two successful test launches of Tactical Tomahawk (Block IV) cruise missiles were conducted in late May 2003 from Columbus, while underway in the Pacific Ocean off the coast of Southern California. Columbus departed Pearl Harbor for another western Pacific deployment in late 2003, and visited Jinhae-gu, South Korea, Singapore, and Japan while taking part in Annual-Ex 2003 (exercise) with various units of the Japanese Maritime Self-Defense Force.
Following a modernization refit at the Puget Sound Naval Shipyard from 2004-2006 in Bremerton, Washington, Columbus returned to Submarine Squadron Seven in Pearl Harbor and departed Pearl Harbor in March 2008 for a regularly scheduled six-month deployment. Deployed with the Seventh Fleet, Columbus supported national taskings and theater security cooperation efforts while making port visits in Saipan, Guam, Okinawa, Sasebo, and Yokosuka, Japan. In January 2009 Columbus was awarded the Submarine Squadron 7 Battle Efficiency (Battle "E") award, given to the submarine crew that best demonstrates technical proficiency and continual mission readiness throughout the previous year.
Columbus returned to Pearl Harbor, Hawaii in August 2012 after completing a six-month deployment that included Seventh Fleet and national mission tasking along with port visits to Japan, South Korea, and Guam. Columbus arrived in the South Korean southern port city of Busan 3 March 2014 as a part of a scheduled deployment in the Western Pacific. In September 2017, Columbus returned to Pearl Harbor from a six-month deployment having performing three national tasking periods, two theater operation periods, and a multinational exercise. Columbus also enjoyed four port visits, including Singapore and Guam.
