SUBASE New London

Located in Groton, Connecticut

Connecticut’s Submarine Stronghold

Welcome to Connecticut, home to the U.S. Navy’s premier submarine hub, Naval Submarine Base New London. Nestled in Groton along the Thames River, this base drives underwater defense and training. This guide to military bases in Connecticut explores its role, history, economic contributions, and community life, helping U.S. service members and families thrive during PCS or TDY assignments in the Nutmeg State.

A Legacy of Naval Power

The story of Naval Submarine Base New London began in 1868, when Connecticut donated 112 acres for a naval yard. By 1872, the Navy built a pier and two buildings, but growth was slow. In 1916, the arrival of submarines like the G-1 transformed it into the Navy’s first submarine base. World War II expanded the base to nearly 500 acres, housing thousands. The 1954 commissioning of USS Nautilus, the world’s first nuclear-powered submarine, marked a historic milestone. Today, the base remains the “Home of the Submarine Force.”

Boosting the Region

Naval Submarine Base New London powers Connecticut’s economy, contributing hundreds of millions annually. It supports Groton’s businesses, from restaurants to shops, and employs thousands of locals. Service members and families settle into 1,500 housing units, access DoDEA schools, and use the base’s medical clinic. Community events, like 2025 Thames River festivals, connect families to the area’s maritime charm. A new 2024 microgrid ensures reliable power, strengthening the base and region.

Essential Base Facilities

The base hosts critical operations and training. Here’s a look at its vital facilities:

  • Naval Submarine Base New London (Groton): Homeports 15 attack submarines and supports 70 tenant commands, including 2024 submarine deployments.

  • Naval Submarine School (Groton): Trains submariners in tactics and survival skills, like escape drills.

  • Mina Salman Pier (Groton): Docks submarines for maintenance, with a 2025 pier extension underway.

Strategic Impact

SUBASE New London is the Navy’s submarine capital. It trains thousands of submariners and maintains a fleet of attack submarines, ready for global missions. In 2024, ships like USS Newport News returned from surge deployments, showcasing readiness. The base’s 2024 microgrid launch ensures uninterrupted operations, even during outages. Its role in NORAD and NATO strengthens U.S. defense, with no credible 2024 threats reported.

Community and Culture

The base builds a tight-knit community. Housing, schools, and healthcare keep families grounded. Events like base tours or riverfront festivals spark connection. Explore Groton’s historic villages, stroll New London’s waterfront, or hike nearby trails.
