The USS Columbia, the last of the Los Angeles (688) class, fast-attack nuclear powered submarines, is named for Columbia, IL, Columbia, MO, and Columbia, SC. It was built by the Electric Boat Co., a division of General Dynamics.

The U.S. Navy commissioned the USS Columbia (SSN 771) on Monday, October 9, 1995 at the North Lake Naval Base at New London, CT. Columbia, IL Mayor Les Schneider was on the commissioning platform with other civilian dignitaries from the namesake cities. They were joined by officials of the federal government, the Navy and the Electric Boat Co., the boat's contractor. Delegations also represented the other namesake cities. The USS Columbia was christened by First Lady Hillary Rodham Clinton on Saturday, September 24, 1994.

COLUMBIA was built with the state-of-the art SEAWOLF technology. Application of this technology makes this ship the most modern submarine in the world. Both construction methods and computerization make COLUMBIA stand out as a unique submarine platform among the 688 improved class. This submarine is one of the most versatile weapons platforms ever placed in the world's oceans, capable of long range Tomahawk strike operations, anti-submarine and surface shipping operations, surveillance and intelligence gathering, and special forces insertions.
