General Dynamics Electric Boat, headquartered in Groton, Connecticut, operates as a defense-focused manufacturing unit within General Dynamics. Founded in 1899 to build the Navy's first modern submarine, the USS Holland, it has a long history of submarine design and construction. It later produced the Nautilus, the world's first nuclear-powered submarine, and now serves as the design yard and prime contractor for the Virginia-class program while also developing the Columbia-class ballistic-missile submarine.

Electric Boat's primary customer is the United States Navy, and its work focuses on submarine design, development, and production. In 2026 the company expanded facilities in Groton and North Stonington, Connecticut, signaling ongoing growth in domestic submarine programs.
