The Submarine Force Museum, located on the Thames River in Groton, Connecticut, maintains the world's finest collection of submarine artifacts. It is the only submarine museum operated by the United States Navy, and as such is the primary repository for artifacts, documents and photographs relating to U.S. Submarine Force history. The museum traces the development of the "Silent Service" from David Bushnell's Turtle, used in the Revolutionary War, to the modern Los Angeles, Ohio, Seawolf and Virginia class submarines.
