For over seven decades, Electric Boat (EB)—a subsidiary of General Dynamics—has been America's sole designer and builder of nuclear-powered submarines. Located in Groton, Connecticut, this massive shipyard has constructed every U.S. Navy nuclear submarine class since 1954, from the USS Nautilus to today's Virginia-class vessels. At its peak during the Cold War submarine race, Electric Boat employed over 31,000 workers in confined spaces where asbestos was ubiquitous, making it one of the most contaminated industrial facilities in American history. Workers who were exposed can connect with experienced mesothelioma attorneys and explore VA benefits for Navy-connected claims.
Executive Summary
Electric Boat submarine workers in Groton, Connecticut were exposed to massive concentrations of asbestos during the construction and assembly of nuclear submarines. The confined hull spaces, combined with widespread use of asbestos in insulation, gaskets, fire barriers, and acoustic dampening materials, created one of the highest-risk occupational environments in U.S. shipbuilding. Over 200 nuclear submarines were built at the facility, with peak employment exceeding 31,000 workers. Thousands of former EB workers now face mesothelioma, lung cancer, and asbestosis diagnoses 20-50 years after exposure. Multiple legal pathways to compensation exist, including Electric Boat asbestos claims, trust fund recovery, workers' compensation, and VA benefits for Navy-connected workers.

What Was Electric Boat's Role in US Submarine Manufacturing?
Electric Boat, headquartered in Groton, Connecticut, is the primary shipyard responsible for designing and building nuclear-powered submarines for the United States Navy. Established in 1899 as a diesel submarine manufacturer, EB transitioned to nuclear propulsion following the successful launch of the USS Nautilus in 1954—the world's first nuclear submarine. Since then, Electric Boat has built every U.S. Navy nuclear submarine class.[1]
The submarine classes built at Electric Boat include the USS Nautilus and Seawolf-class (1950s-1960s), Los Angeles-class attack submarines (1970s-1990s), Ohio-class strategic missile submarines (1980s-present), Virginia-class attack submarines (2000s-present), and the Columbia-class ballistic missile submarines currently under construction.
During the height of Cold War submarine competition with the Soviet Union, Electric Boat expanded dramatically. The facility employed more than 31,000 workers at peak capacity in the 1980s, making it one of Connecticut's largest employers. Workers constructed submarines in massive enclosed facilities where asbestos contamination was pervasive. The confined spaces of submarine hulls—where workers labored in narrow compartments insulating pipes, installing electrical systems, and assembling complex mechanical components—created ideal conditions for asbestos fibers to remain suspended in the air.[2]
"The confined environment of a submarine hull created a perfect storm for asbestos exposure. Workers couldn't escape the fibers—they were sealed in these metal tubes breathing contaminated air for hours, day after day, for decades. Many didn't even know asbestos was in the materials they were handling."
— Larry Gates, Senior Advocate, Danziger & De Llano
Why Was Asbestos So Prevalent in Submarine Construction?
Asbestos became the material of choice in submarine manufacturing because of its unique physical properties—heat resistance, fire protection, acoustic dampening, and low cost—that seemed ideal for military applications until the catastrophic health consequences became undeniable. According to shipyard exposure documentation, asbestos appeared in multiple critical applications within submarine hulls.[3]
| Material Component | Asbestos Application | High-Risk Work Activities |
|---|---|---|
| Pipe Insulation | Chrysotile wrapping around steam and hot water pipes | Installing, removing, repairing insulation in confined spaces |
| Boiler Lagging | Asbestos materials covering high-temperature equipment | Maintenance on reactor systems and heat exchangers |
| Electrical Insulation | Asbestos in cable insulation, electrical panels | Electricians installing systems throughout submarine |
| Gasket Materials | Asbestos-reinforced gaskets in pipe connections | Assembly and maintenance of high-pressure systems |
| Fire Barriers | Fireproofing panels protecting critical systems | Installing protective barriers during construction |
| Acoustic Dampening | Sound-reducing panels in submarine compartments | Installing sound-damping materials in hulls |
The problem was exponentially worse in submarine construction than in surface shipbuilding because of the confined spaces. Workers were sealed in narrow metal tubes—sometimes only 20-30 feet long and 10-15 feet in diameter—working with asbestos-containing materials for 8-10 hour shifts. Asbestos fibers accumulated in workers' lungs at rates far exceeding those in other industrial occupations.[4]
Which Electric Boat Workers Faced the Highest Asbestos Exposure?
While all workers at Electric Boat risked asbestos exposure, certain occupations involved direct handling of asbestos-containing materials and experienced disproportionately high exposure levels:[5]
Insulators handled chrysotile-wrapped pipes and boiler lagging daily, cutting, fitting, and securing asbestos insulation in submarine reactor compartments. Pipe fitters connected and sealed thousands of pipes using asbestos gaskets and compounds. Boilermakers assembled and welded high-pressure systems surrounded by asbestos-lagged equipment. Electricians installed systems using asbestos-insulated cables and panels. Welders worked near asbestos insulation that released fibers when heated. Even general laborers moving materials and cleaning work areas were exposed to ambient fibers.
"We didn't know what we were working with. Nobody told us asbestos was dangerous. We just saw the material, used it, and went home covered in dust. Years later, doctors told us we all have asbestos fibers in our lungs. It's like a time bomb that doesn't go off for 30 or 40 years."
— Larry Gates, Senior Advocate, Danziger & De Llano
What Health Risks Do Electric Boat Workers Face?
Asbestos exposure at Electric Boat created risk for multiple serious diseases, most notably mesothelioma—a fatal cancer with no cure and limited treatment options. The latency period means workers exposed decades ago are only now developing symptoms.[6]
Mesothelioma (Pleural and Peritoneal): Malignant mesothelioma develops in the thin layer of tissue covering internal organs. Pleural mesothelioma (lung lining) is the most common form. Median survival ranges from 12-21 months even with aggressive multimodal treatment. Early diagnosis provides better treatment options.
Asbestosis: Chronic scarring of lung tissue caused by inhaled asbestos fibers. Progressive shortness of breath, chest pain, and reduced lung function characterize this disease. While not cancer, it indicates significant exposure and increases mesothelioma risk.
Lung Cancer: Asbestos exposure significantly increases non-small-cell lung cancer risk, particularly in workers with concurrent asbestosis or smoking history. May develop 15-40 years after initial exposure.
Other Conditions: Pleural thickening, pleural effusion, and benign asbestos pleural disease also affect former EB workers and warrant ongoing medical monitoring.
What Is the Timeline for Developing Mesothelioma After Electric Boat Exposure?
Mesothelioma typically develops 20-50 years after initial exposure, with an average latency of 30-40 years. Workers exposed at Electric Boat in the 1970s might not develop symptoms until the 2000s or 2010s. This extended latency creates challenges for documentation but also means veterans benefits and legal claims remain available long after exposure ended.[7]
Connecticut's statute of limitations for mesothelioma claims uses the "discovery rule"—the clock starts at diagnosis, not exposure. This allows claims filed decades after exposure occurred. Secondary exposure is also a concern: workers who brought asbestos fibers home on clothing exposed family members to contamination.
What Legal Options Are Available to Electric Boat Workers?
Former Electric Boat workers diagnosed with mesothelioma have multiple compensation pathways that can be pursued simultaneously:[8]
Asbestos Trust Fund Claims: Over 60 manufacturers that supplied products to Electric Boat have established trust funds totaling more than $30 billion. Trust fund claims offer streamlined processing (6-12 months), no litigation required, and can be filed alongside other claims. Most EB workers qualify for multiple trust fund claims since products came from dozens of manufacturers.[9]
Personal Injury Lawsuits: Workers can sue asbestos product manufacturers for negligence, strict product liability, and failure to warn. Connecticut courts have been historically favorable to mesothelioma plaintiffs with substantial jury awards.
Connecticut Workers' Compensation: Former EB employees may qualify for medical treatment costs (100% coverage), partial wage replacement, permanent disability payments, and death benefits for surviving family members.
VA Benefits: Navy submarine veterans qualify for VA disability benefits including monthly payments ($200-$4,000+ depending on rating), free healthcare through VA Medical Centers, and prescription coverage. Veterans should file using VA Form 21-526EZ.[10]
"Most workers don't realize they can pursue multiple compensation sources at the same time. The key is understanding which sources apply to your specific situation—and that's where experienced legal guidance makes the difference. Some Electric Boat workers have recovered well over $1 million by pursuing all available avenues."
— Larry Gates, Senior Advocate, Danziger & De Llano
Why Should Electric Boat Workers Hire a Mesothelioma Attorney?
Navigating mesothelioma compensation requires specialized knowledge. Mesothelioma lawyers provide case evaluation, document investigation, trust fund navigation, litigation support, VA claim assistance, and medical coordination. Most mesothelioma cases are handled on contingency—you pay nothing unless compensation is awarded.[11]
