Naval Submarine Base New London

Naval Submarine Base New London at a glance

Naval Submarine Base New London supports submarine operations and submariner training in southeastern Connecticut. Its public mission includes shore facilities and services for combat-ready submarines and crews. Named mission partners include Naval Submarine School, the Submarine Learning Center and Naval Undersea Warfighting Development Center, bringing operational readiness and professional education into the same installation community.

Despite the New London name, the base is in Groton on the Thames River. Its origins were a nineteenth-century Navy yard, with submarines arriving during World War I before the submarine base and school designation. The installation later became associated with the nuclear submarine era, including USS Nautilus. Groton and New London are separate communities; the base name does not identify its municipality.

2. Clarify lodging and housing arrangements before booking. Ask about availability, required approvals and how to handle a late arrival.
