Established in 1955, the museum was originally operated by the Electric Boat Division of General Dynamics and was known solely as the Submarine Library. The Submarine Force Library and Museum soon gained respect for its archival and research value. The submarine builder eventually realized the huge value of such a collection of documents, artifacts, and information and in 1964, General Dynamics donated the collection to the US Navy.

The museum’s collections include more than 33,000 artifacts (including the first nuclear-powered submarine in the world, the USS Nautilus, launched in 1955 and decommissioned in 1980). The museum also includes midget submarines from World War II; working periscopes salvaged parts from the nuclear USS NR-1, a submarine control room, models of submarines, and the Explorer, an early U.S. research submarine.

In addition to its large collection of submarines and related objects, the museum also has a library with around 20,000 documents and 30,000 photos related to the history of submarine development.
