// Strategic Significance
Naval Submarine Base New London is the oldest submarine base in the US and home to the Naval Submarine School — where all US Navy submarine officers and many enlisted receive training. The base homeports Virginia-class fast attack submarines and is the primary submarine training installation in the Atlantic. Groton Connecticut is considered the Submarine Capital of the World and hosts Electric Boat — the primary US submarine manufacturer.
// Civilian Impact Assessment
Groton and New London are economically dependent on the submarine base and Electric Boat manufacturing. The Thames River at the base is a critical waterway for submarine transit. The concentration of submarine construction and training creates a strategically valuable target cluster. Hurricane and nor'easter exposure creates compound natural and security emergency planning requirements.
// Evacuation & Shelter Guidance
New London County has detailed hurricane and nor'easter evacuation plans. The Thames River bridges are critical infrastructure for evacuation from Groton. Monitor Connecticut DEMHS broadcasts. Electric Boat and submarine base emergency operations may affect civilian traffic. Know alternate river crossing points in case primary bridges are affected.
