About this Unit

After the war, the dry dock continued its service, supporting both conventional and nuclear submarines during the Cold War era. Over the decades, USS Oak Ridge underwent several upgrades and remained an essential asset in the Navy's submarine support fleet until its decommissioning in 2023.
