General Dynamics Electric Boat is a business unit of General Dynamics with headquarters in Groton, CT. The world’s first and finest submarine builder, Electric Boat was established in 1899 to complete the U.S. Navy’s first modern commissioned submarine, USS Holland. Designed and built by Electric Boat, USS Nautilus, the world’s first nuclear-powered submarine, was launched in 1954. Electric Boat has designed and delivered 17 of the U.S. Navy’s 20 classes of nuclear submarines. Now in its second centennial of submarine building, EB is the design yard and prime contractor for the Virginia-class submarine program, currently in production. EB is also designing and developing the Columbia-class ballistic-missile submarine which will replace the current Ohio class beginning in 2027.
