General Dynamics Electric Boat just landed a hefty contract modification—about $15.4 billion—to keep the Columbia-class submarine program moving. A big chunk of that work is heading to Connecticut’s Groton shipyard.
The deal also covers prep for future Columbia boats and long-lead materials. Some of it will go to the Rhode Island facility at Quonset Point.

For Connecticut towns and suppliers, this agreement means shipbuilding and related industries can count on steady work into the mid-2030s. Electric Boat’s presence in the region just keeps growing, and its role in national defense is hard to overstate.
This article digs into what the contract modification really means—for the company, the Navy’s plans, and the Connecticut economy. It’s also a massive jobs engine for cities and towns all over the state.
Columbia-class contract: what it covers and where the work happens
The modification focuses on pushing construction and procurement for the third Columbia submarine, USS Groton (SSBN 828). It also supports engineering and development for future Columbia boats.
About 21% of the work will happen at Electric Boat’s Groton, Connecticut, shipyard. Roughly 4% is set for the Quonset Point facility in Rhode Island.
This funding lets Electric Boat move ahead with long-lead items and early construction activities. The idea is to get ready for full production under future contracts.
Electric Boat leads the Columbia-class program, so the Navy is relying on them to keep things on track. They expect to finish the current work package by June 2035.
That timeline lines up with the phased rollout of the rest of the submarines in the class.
Local lawmakers and industry observers want advanced construction to turn into steady, full-scale contracts. That would give suppliers stronger demand signals and keep Connecticut’s shipbuilding base healthy.
Congressmember Joe Courtney has pointed out that predictable funding is key. He’s been saying it for years—steady money means steady jobs at EB and across its network of vendors.
Groton and Quonset Point: where the work lands
So, what does this mean on the ground? Groton, the state’s historic shipbuilding hub, will see a steady flow of activity.
Quonset Point gets a smaller, but still meaningful, share. Groton will stay at the heart of the Columbia-class effort as the main production and integration site.
The Rhode Island yard will handle specific manufacturing and procurement pieces. This cross-state teamwork fits into a bigger defense-industrial strategy that keeps high-skilled jobs close to home.
Families in Connecticut and the Northeast benefit from this approach.
Virginia-class work and Block VI considerations
Electric Boat isn’t just working on Columbia-class boats. They’re also busy with Virginia-class fast-attack submarines.
They’ve landed a recent modification worth about $12.4 billion for Virginia-class work. The company is pushing the Navy to award the authorized Block VI contract to keep production humming.
Right now, they’re handling commissioning and delivery for subs like USS Iowa and USS Idaho. The christening of USS Utah is also on the schedule.
It’s a packed calendar, with Columbia-class commitments running alongside Virginia-class production.
Connecticut’s submarine-focused workforce really depends on this steady mix of program activity. It keeps facilities busy and skilled labor in high demand.
In Connecticut, it’s not just about the submarines themselves. Suppliers, subcontractors, and service firms all play a part—handling design, testing, maintenance, and parts.
Company leaders keep stressing how much they need stable, predictable funding from the federal government. That’s what keeps the regional defense economy resilient and protects skilled jobs in towns across the state.
Jobs, workforce, and regional impact in Connecticut
Electric Boat employs about 16,000 people in Connecticut and around 24,000 overall. The company plans to hire roughly 8,000 people this year as the Columbia and Virginia programs ramp up.
This hiring push will touch a bunch of CT communities linked to shipbuilding and supplier networks. Both coastal and inland towns host engineering, fabrication, and administrative operations.
- Groton
- New London
- Waterford
- Mystic
- Norwich
- Montville
- Ledyard
- East Lyme
- Stonington
Beyond Groton, towns like Norwalk and Bridgeport could see some indirect benefits through supplier networks and logistics. Still, eastern Connecticut holds most of the direct production.
Local officials seem hopeful that the steady stream of submarine work will keep manufacturing careers alive. They expect it’ll attract more aerospace and defense vendors and maybe even boost Connecticut’s status as a defense hub.
If you walk around these communities, you’ll probably hear folks talk about job fairs, wage bumps, and steady employment tied to shipbuilding, naval engineering, and high-tech fabrication. There’s a real sense of anticipation about what’s next for the workforce here.
