USS Columbia (SSN-771) is the 21st flight III, or Improved (688i) Los Angeles -class attack submarine of the the United States Navy . Commissioned in 1995, the submarine is assigned to Submarine Squadron 7 and homeported in Joint Base Pearl Harbor-Hickam .[3]
It is the eighth U.S. warship to bear its name, though the first to be named for three cities: Columbia, South Carolina ; Columbia, Missouri ; and Columbia, Illinois .[4]
History
The contract to build Columbia was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut , on 14 December 1988 and her keel was laid down on 21 April 1993.[4] She was the 33rd Los Angeles-class boat built by EB, and was launched on 24 September 1994 with the slide down a 1,300-foot wooden ramp, the last American submarine to do so, giving her the title of "The Last Slider".[4] Columbia was sponsored by Hillary Clinton , and commissioned on 9 October 1995.[4]
From March to May 1999, Columbia operated off the California coast, participating in exercises and making port visits.[5]
In 2011, the sub made a western Pacific deployment, including a port visit at Yokosuka , Japan.[6]
In May 2014, Columbia left on a western Pacific deployment. The sub stopped in Yokosuka on 5 November[7] and returned to its homeport of Joint Base Pearl Harbor-Hickam on 21 November.[8]
In July 2015, the ship was awarded the Arleigh Burke Fleet Trophy , as the Pacific Fleet ship that improved the most in the previous year, based on the Battle Efficiency Competition .[8]
In late 2015, Columbia made a six-month patrol in the western Pacific, making port visits at Yokosuka[9] and Sasebo , Japan[10] ; and Guam ; and returning to Pearl on 4 May 2016. The sub visited Yokosuka again in October[11] .
In 2018, the sub made another WestPac deployment, stopping at Yokosuka in May.[12]
From October 2018 until 16 July 2020, the submarine underwent a mid-life overhaul at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility.[13]
In September 2021, the sub participated in the 62nd annual UNITAS exercise off South America.[14]

Future U.S. submarine of the name
In 2016, Navy officials announced that the lead ship of the planned Columbia classof ballistic missile submarines , would also be named Columbia (SSBN-826) , after the District of Columbia . The name was officially announced on 25 July 2016 by U.S. Secretary of the Navy Ray Mabus .[19] The vessel is expected to enter service in 2031,[citation needed ] at which point the attack sub Columbia would be 37 years old. As of 2022, 36 Los Angeles -class boats have been retired, and only three were in service longer than 37 years. On June 3, 2022, the Navy announced that the new sub would be named USS District of Columbia .[20]
