New London Naval Submarine Base, Connecticut

A major East Coast submarine base, located on over 680 acres on the Thames River, and home to 15 nuclear submarines. A few miles downstream is the General Dynamics Electric Boat Division, which made many of the subs stationed at the base. The Navy dredged a deeper channel in the river leading from the ocean to the base, in order to accommodate the then-new $4 billion Sea Wolf attack sub, built at Electric Boat. Over 32,000 active-duty service members and their dependents, civilian workers and contractors, retirees, and Reservists are associated with the base.
