About
Electric Boat was established in 1899 to construct a 54-foot submersible developed by John Holland; USS Holland was accepted by the U.S. Navy a year later. The company designed and built USS Nautilus, the world's first nuclear-powered submarine, launched in 1954. It states it has more than 23,000 employees and is certified to ISO 9001, ISO 14001 and ISO 45001.
The 118-acre Groton shipyard includes the Land Level Ship Construction Facility, built in the 1970s for the TRIDENT program, two additional dry docks and more than 400,000 sq ft for design work. The 125+ acre Quonset Point facility, established in 1973, manufactures and outfits hull cylinders using an Automated Steel Processing Facility. In 2026 Electric Boat received the floating dry dock Atlas, built by Bollinger Shipyards, to launch Columbia-class submarines.
