In 2019 EB received a contract with Naval Sea Systems Command to begin procuring materials for the Block V variant of the Virginia-class. The submarines of this type will build on the improvements to allow them to spend less time in the yard. The boats of Block IV Virginias will cost less than Block III, as Electric Boat reduced the cost of the submarines by increasing efficiency in the construction process. The company builds the submarine along with Huntington Ingalls Industries Newport News Shipbuilding. It is the largest single shipbuilding contract in the service's history. In April 2014, EB was awarded a $17.8 billion contract with Naval Sea Systems Command for ten Block IV Virginia-class attack submarines. įrom the mid-1970s to the present, EB has been one of only two submarine manufacturers in the United States, with the other being Newport News Shipbuilding in Virginia. ![]() Electric Boat's first submarine, Holland, was scrapped in 1932. In 2002, EB conducted preservation work on Nautilus, preparing her for her berth at the US Navy Submarine Force Library and Museum in Groton, Connecticut where she now resides as a museum. Submarines of the Ohio, Los Angeles, Seawolf, and Virginia classes were also constructed by Electric Boat. Įlectric Boat built the first nuclear submarine, USS Nautilus, which was launched in January 1954, and the first ballistic missile submarine, USS George Washington, in 1959. General Dynamics acquired Convair the following year, and the holding company assumed the "General Dynamics" name while the submarine-building operation reverted to the "Electric Boat" name. In 1952, Electric Boat was reorganized as General Dynamics Corporation under John Jay Hopkins. Since 1974, only Electric Boat and Newport News have built submarines for the US Navy.ĭuring World War II, the company built 74 submarines at the Groton plant, while Elco built nearly 400 PT boats, and Electric Boat ranked 77th among United States corporations in the value of World War II military production contracts. Several other yards ( New York Shipbuilding, Ingalls and Fore River Shipyard) as well as Mare Island built submarines in the late 1950s through the early 1970s. Three other yards ( Manitowoc, Mare Island, and Cramp) produced submarines only during World War II. Starting in the early 1930s, EB was one of only two major US submarine manufacturers (the other being the Portsmouth Navy Yard) until the late 1950s. ![]() ![]() EB was the lead yard for several classes of submarines ( Perch, Salmon, Sargo, Tambor, Gar, Mackerel and Gato) prior to World War II. Cuttlefish was the first submarine built at EB's plant in Groton, Connecticut which has been its primary submarine manufacturing facility ever since. Interwar Īfter the war, the US Navy did not order another submarine from Electric Boat until Cuttlefish in 1931. During this era, the company designed submarines of the B, C, D, E, K, L, M, N, AA-1, O, R, and S classes.ĭuring the World War I era, the company and its subsidiaries (notably the Electric Launch Company, or Elco) built 85 submarines via subcontractors and 722 submarine chasers for the US Navy, and 580 80-foot motor launches for the British Royal Navy. įrom 1907 to 1925 Electric Boat designed submarines for the US Navy and subcontracted their construction to the Fore River Shipyard in Quincy, Massachusetts and other shipyards. Some foreign navies were interested in Holland's latest submarine designs, and so purchased the rights to build them under licensing contracts through the company these included the United Kingdom's Royal Navy, the Imperial Japanese Navy, the Imperial Russian Navy, and the Royal Netherlands Navy. The success of Holland VI created a demand for follow-up models (A class or Plunger class) that began with the prototype submersible Fulton built at Electric Boat. Holland VI was the first submarine that this shipyard built, which became USS Holland when it was commissioned into the United States Navy on April 11, 1900-the first submarine to be officially commissioned. The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. It has been the primary builder of submarines for the United States Navy for more than 100 years. General Dynamics Electric Boat ( GDEB) is a subsidiary of General Dynamics Corporation.
