Los Angeles-class attack submarine USS Cheyenne arrived at the Portsmouth Naval Shipyard on Tuesday, Nov. 23, to undergo system upgrades and maintenance work. The sub is the first of its class to go through the Navy’s service life-extension program.
Named for the city of Cheyenne, Wyo., the 360-foot submarine was commissioned in 1996. It is capable of supporting missions such as anti-submarine warfare, anti-surface ship warfare, strike warfare, intelligence, surveillance, and reconnaissance. Last year, the Cheyenne completed two Western Pacific deployments in support of the Global War on Terror. Its current homeport is Groton, Conn.
Portsmouth will serve as host community for the Cheyenne’s crew, which includes more than 140 members. Cmdr. Samuel Bell assumed command of the Cheyenne in January of this year.
