For those looking for something a little bigger – General Dynamics Electric Boat in Groton – has built nuclear warships and submarines for the U.S. Navy. At its locations in Groton, New London and just over the border in Quonset Point, the company builds, repairs and tests some of the biggest, most vital submarines for the U.S. military arsenal. 

Liz Power, spokeswoman for Electric Boat, in Groton the company puts together the submarine and actually tests the massive underwater boats off the coast. The company works on maintenance and modernization of the submarines already active in the Navy fleet. About a 15-minute drive from Groton, the New London facility houses the majority of their engineers who are currently working on the designs for new submarines – including nuclear and attack submarines.
