The Navy constructed
nuclear-powered submarines in its own shipyards at Mare Island, California,
and Kittery, Maine. But private companies have built most submarines.
The oldest of these is Electric Boat Co., Groton, Connecticut, which sold
the Navy its first submarine in 1900 and also built the first nuclear-powered
submarine. Other commercial shipyards included Newport News Drydock and
Shipbuilding Co., Virginia, which built its first submarine in 1905; New
York Shipbuilding Corp., Camden, New Jersey; Fore River Shipbuilding Co.,
Quincy, Massachusetts; and Ingalls Shipbuilding Corp., Pascagoula, Mississippi.
Submarines also return to shipyards for periodic overhauls and maintenance.
