The crew of the Los Angeles-class fast-attack submarine USS Pittsburgh held an inactivation ceremony at the US Naval Undersea Museum in Keyport, Washington, on Friday, January 17, to celebrate the vessel’s 35 years of service.

The occasion marked the crew’s final public event before the submarine is officially decommissioned in the controlled industrial area at Puget Sound Naval Shipyard in Bremerton, Washington.

Inactivation is the process in which a submarine will be de-fueled, with the hull retained in safe storage until decommissioning, when the boat is then taken out of active service and the crew is reassigned to another ship or command.

Pittsburgh completed its last deployment on February 25, 2019. The boat and its crew then made their first arctic transit for a final homeport change from Groton, Connecticut, to Bremerton, arriving on May 28, 2019, to commence the inactivation and decommissioning process.

The submarine is the fourth US Navy vessel to be named for the city of Pittsburgh, Pennsylvania.
