The USS Jacksonville (SSN-699) was a Los Angeles-class nuclear-powered attack submarine, notable for being the only vessel of the U.S. Navy named after Jacksonville, Florida. Constructed by the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, her keel was laid on 21 February 1976 following the contract award on 24 January 1972. She was launched on 18 November 1978 using a pontoon system designed for Ohio-class Trident submarines and was commissioned on 16 May 1981. Mrs. Dorothy Jean Bennett sponsored the vessel. Measuring approximately 360 feet (110 meters) in length, with a beam of 33 feet (10 meters) and a draft of 32 feet 15 inches (10.13 meters), Jacksonville was powered by an S6G reactor. This propulsion system enabled her to reach speeds of over 32 knots submerged and 15 knots surfaced. Her operational depth ranged up to about 800 feet (240 meters), with a safe depth limit of 1,200 feet (370 meters) and a crush depth estimated at 1,800 feet (550 meters). The submarine's crew comprised 12 officers and 121 enlisted personnel. Jacksonville's armament included four 533mm torpedo tubes (TT MK 67) capable of launching Tomahawk cruise missiles, along with MK 48 and MK 48 ADCAP torpedoes, with 22 reloads plus two additional in emergencies. Her service history was marked by notable deployments, including two around-the-world cruises in 1982 and 1985, and multiple deployments to the Western Atlantic and Mediterranean. She participated in fleet exercises and was involved in a shock trial program after her 1988 modernization overhaul. During her career, she experienced four collisions with other vessels. In 2009, her homeport shifted from Norfolk to Pearl Harbor. Jacksonville was involved in a minor fire during a refueling overhaul in 2004 but remained in operational status. Her final deployment occurred in August 2017, after which she was decommissioned on 16 November 2021 at Puget Sound Naval Shipyard, marking 36 years of service. Her decommissioning ceremony was held in Keyport, Washington, and her legacy includes extensive operational service, tactical significance, and a long history of strategic deployments.
