Groton is the Submarine Capital of the World — Naval Submarine Base New London, directly across the Thames River from New London, is the US Navy's primary East Coast submarine base and home to the most advanced nuclear-armed submarines in the fleet. General Dynamics Electric Boat's main submarine construction facility is also in Groton, producing Virginia-class and future Columbia-class ballistic missile submarines. In any conflict involving Iran or other adversaries with anti-ship capability, US submarine infrastructure becomes a high-priority target. Hurricane and storm surge risk from Long Island Sound are the primary natural hazards.
