Electric Boat History

Established in 1899, Electric Boat has established standards of excellence in the design, construction and lifecycle support of submarines for the U.S. Navy. Primary operations are the shipyard in Groton, CT, the automated hull-fabrication and outfitting facility in Quonset Point, RI, and an engineering building in New London, CT. The current workforce is more than 14,000 employees.
