Connecticut is the undisputed center of U.S. submarine manufacturing, home to General Dynamics Electric Boat in Groton — the only full designer and builder of nuclear-powered attack submarines in the country — and a skilled trades workforce that represents the sharpest edge of American naval manufacturing.
Get Started
General Dynamics Electric Boat dominates Connecticut's maritime manufacturing sector, supported by a deep tier-one and tier-two submarine supplier base and a Naval Submarine Base New London presence that anchors the regional economy.
Electric Boat is the sole designer and primary builder of nuclear-powered attack submarines for the U.S. Navy, producing Virginia-class fast-attack submarines and Columbia-class ballistic missile submarines. Its Groton facility is the largest industrial employer in Connecticut and one of the most consequential defense manufacturers in American history.
🌐 ~20,000 CT/RI employees
Naval Submarine Base New London is the primary submarine base on the East Coast and the home of submarine school for the U.S. Navy. The base creates significant demand for civilian maintenance, logistics, and technical support employment in the greater Groton-New London area.
🌐 ~9,000 military and civilian personnel
Electric Boat's Quonset Point facility in Rhode Island manufactures submarine sections that are shipped to Groton for final assembly, creating a bi-state production network with major ripple effects across Connecticut's submarine component supply chain.
🌐 ~5,000 RI employees (CT supply chain)
Electric Boat in Groton is the sole designer and primary builder of Virginia-class attack submarines — the most sophisticated vessels in the U.S. Navy's fleet. Careers here place technicians at the absolute frontier of American manufacturing and defense technology.
The Virginia-class submarine program runs through the 2040s and the Columbia-class ballistic missile submarine program extends even further. Connecticut submarine technicians enter careers backed by federal contracts that provide extraordinary long-term job security.
Electric Boat's wages and benefits are among the most competitive of any manufacturing employer in New England, reflecting the extreme technical demands and national security importance of submarine construction. Workers also benefit from strong union representation.
Building nuclear submarines is not just a job — it is a direct contribution to American national security. Connecticut's submarine workforce has a culture of pride and precision that creates a uniquely rewarding career environment for technically minded trades workers.
