For much of the 20th century, Groton, Conn., was more than a shoreline town with a naval base and a shipyard. It was one of the places where America’s underwater military power was built, trained and sustained, earning the nickname “Submarine Capital of the World.” The identity was not just promotional language. Naval Submarine Base New London in Groton became the Navy’s first submarine base in the 1910s, and Electric Boat grew into one of the country’s central builders of nuclear-powered submarines. For decades, the region’s economy, politics and sense of purpose revolved around that industrial mission.
Then the Cold War ended, and Groton’s old certainty faded with it.
As military priorities shifted after the fall of the Berlin Wall, the southeastern Connecticut region lost jobs, momentum and, in many ways, confidence. The Wall Street Journal reported this week that Groton suffered deeply after Cold War military spending dried up, leaving behind a local economy that had to adjust to a smaller defense footprint and a less certain future. Connecticut state data also show how much the broader town changed over time: Groton’s population fell from 45,144 in 1990 to 39,907 in 2010, reflecting the long aftershocks of deindustrialization and slower growth.
Now the town is being asked to matter again in a very big way.
With the Navy under pressure to expand and modernize its undersea fleet amid intensifying strategic competition, especially with China, Groton has moved back toward the center of the national security map. Electric Boat, headquartered in the town, is one of the key companies responsible for building both Virginia-class fast-attack submarines and the Columbia-class ballistic missile submarines that are meant to replace the aging Ohio-class fleet. In March, the Navy awarded Electric Boat a contract modification worth about $15.38 billion for additional Columbia-class design, support and supplier-development work. Around the same time, company officials and Connecticut reporting said Electric Boat planned to hire 8,000 people in 2026, including roughly 2,250 in Groton, as it accelerates production.
That number alone explains why Groton suddenly feels consequential again.
An 8,000-person hiring push is not routine recruiting. It is the kind of labor demand that can reshape an entire region. According to Connecticut and local business reporting, Electric Boat’s total workforce is already around 24,000, with about 16,000 of those workers based in Connecticut. The company is not just adding a few tradespeople; it is trying to scale up across trades, engineering, design and support roles at a pace that local officials themselves describe as extraordinary. In March, Electric Boat President Mark Rayha called the moment a period of “unprecedented growth and demand for submarines.”
The strategic rationale is not hard to see.
Congress and the Navy have been pouring money into the submarine industrial base because submarine production has become a bottleneck and a priority at the same time. The Columbia-class program is one of the Pentagon’s most sensitive modernization efforts, while the Virginia-class fleet remains central to conventional undersea warfare and deterrence. Official Navy budget documents continue to emphasize major shipbuilding outlays, and the supplier-development language in the March Electric Boat contract underscores a wider effort to strengthen not only the yard itself but also the companies that feed parts and labor into it. Groton is not being revived for nostalgic reasons. It is being leaned on because Washington needs submarines.
But reclaiming an identity is not the same thing as having the capacity to live up to it.
That is the tension hanging over Groton’s comeback story. The Wall Street Journal’s account made clear that the town’s revival is colliding with a practical problem familiar to many fast-growing places: there may not be enough workers, homes, or transportation capacity to support the scale of expansion now being demanded. Groton and the surrounding region are trying to respond, but decades of slower growth left them without the kind of slack that makes a sudden surge easy to absorb.
Housing may be the most obvious strain point.
The region’s shortage is no longer a speculative concern. Connecticut Public reported last year that Groton would need more than 6,000 additional homes to accommodate growth tied to Electric Boat and the Naval Submarine Base. Since then, local and regional officials have tried to move projects forward, but the market remains tight. CT Insider reported just days ago that eastern Connecticut is in the middle of a housing crunch intensified by Electric Boat hiring, even as developers push new projects in Groton, Stonington and elsewhere. Rents at one newly expanded apartment complex in nearby Mystic were reported to range from $2,050 to $4,275 a month, while advocates said affordable inventory remained scarce. Groton’s own economic development arm launched a housing study last year specifically to prepare for projected Electric Boat job growth.
That leaves many incoming workers with an awkward choice: commute longer distances, pay high housing costs, or decide not to relocate at all.
Transportation adds another layer of friction. CT Insider reported this month that the scale of Electric Boat’s recruitment effort is forcing new questions about whether southeastern Connecticut’s transit systems and road infrastructure can handle the influx. In practical terms, that means traffic, bridge congestion and longer travel times for workers trying to reach a shipyard that is growing faster than the surrounding built environment. A defense boom sounds powerful in Washington budget language, but on the ground it often looks like clogged commutes and parking stress before it looks like prosperity.
Training is the other major challenge.
A submarine yard cannot simply hire from any available labor pool and expect instant results. The work depends on welders, pipefitters, electricians, designers, engineers and quality-control staff with highly specific skills. Connecticut and regional workforce groups have been trying to speed up that pipeline. SENEDIA’s New England submarine shipbuilding partnership says it is running approved training programs for submarine industrial-base suppliers, while Connecticut’s Office of Workforce Strategy has continued to coordinate broader workforce initiatives. Electric Boat itself is advertising entry-level trade opportunities for high school seniors and recent graduates, signaling how aggressively it is trying to widen the funnel.
Still, speed has limits in a business this specialized.
A region can launch training cohorts quickly, but it cannot instantly produce experienced submarine builders. That matters because the Groton push is not just about growth; it is also about execution risk. The submarine industrial base has spent years dealing with schedule pressure and workforce gaps. Even the March Navy contract modification for Electric Boat included specific support for supplier development enhancement, an acknowledgment that the broader network remains under strain. Groton may be recovering some of its Cold War importance, but it is doing so in a labor market where skilled manufacturing workers are difficult to find and even harder to retain.
There are signs, however, that the rebound is becoming visible beyond the yard gates.
Electric Boat has been physically expanding its regional footprint, including its purchase last year of the former Macy’s property at Waterford’s struggling Crystal Mall, where about 700 employees are expected to work by March 2027. The company’s broader landholdings in Connecticut have grown, and local officials have pitched the investment as both a defense necessity and an economic-development opportunity. In that sense, Groton’s revival is not confined to one shipyard; it is beginning to shape nearby commercial real estate, employment patterns and municipal planning.
The symbolism matters too.
Naval Submarine Base New London still describes itself as located in the “Submarine Capital of the World,” and the phrase has survived because the institutional bones of that identity never disappeared. The base remains a major hub, supporting more than 70 tenant commands and thousands of active-duty, reserve and civilian personnel. It is also still the “Home of the Submarine Force,” a phrase that helps explain why Groton’s civic identity has remained so bound up with undersea warfare even during leaner years. The town never really stopped being a submarine town; it simply spent several decades being a smaller, less certain one.
That is why the current moment feels both promising and uneasy.
On one level, this is exactly the kind of industrial revival many American towns say they want: high-value manufacturing, federal investment, national importance and thousands of jobs. On another, Groton’s experience shows how hard it is to restart a place at strategic scale after years of drift. The labor has to be trained. The housing has to be built. The roads have to function. The surrounding towns have to absorb the pressure. The old title alone does not solve any of that.
For Washington, Groton’s comeback is part of a military imperative. For Groton, it is something more personal.
It is a chance to convert a famous industrial past into a viable future without being crushed by the demands of that future. After 30 years of post-Cold War diminishment, the town is being asked to deliver again not just to remember what it once was, but to become essential enough that the old nickname means something current and concrete. The question now is not whether Groton can call itself the submarine capital. It is whether it can build, house, train and move enough people to earn the title all over again.
