Electric Boat Division of General Dynamics — located in Groton, Connecticut — is the United States Navy’s primary submarine construction contractor, building nuclear attack submarines, ballistic missile submarines, and submarine-related vessels throughout the nuclear submarine era. Electric Boat constructed the Navy’s first nuclear submarine (USS Nautilus, SSN-571) and has built the majority of the Navy’s nuclear attack submarines — Los Angeles class, Seawolf class, and Virginia class — as well as Ohio-class ballistic missile submarines. Electric Boat’s submarine construction involved asbestos-containing materials throughout the steam systems, machinery spaces, and engineering compartments of every submarine built at the Groton facility. Submarine construction presents the most confined asbestos work environment in naval shipbuilding — workers installing asbestos insulation in spaces that would become permanently confined once the pressure hull was closed. Electric Boat workers — including pipefitters, insulation workers, boilermakers, electricians, and all shipbuilding trades — were exposed to asbestos from the insulation materials used throughout each submarine. Publicly filed asbestos litigation records document General Dynamics Electric Boat in the naval asbestos framework: formal proceeding identification, asbestos health documentation in the submarine construction context, and Electric Boat proposal documentation in asbestos proceedings.

Asbestos at Electric Boat / General Dynamics

Nuclear submarine construction: Electric Boat’s primary work was the construction of nuclear-powered submarines — vessels with nuclear steam supply systems and associated steam turbine propulsion plants that required extensive asbestos insulation throughout their engineering spaces. Submarine nuclear steam systems operated at high pressures and temperatures requiring the most robust asbestos insulation systems in naval construction.

Confined hull insulation work: Submarine hull construction required insulation workers and pipefitters to install asbestos pipe covering and block insulation in the most confined spaces in naval shipbuilding. The submarine’s pressure hull — once closed — created the enclosed environment in which asbestos-exposed crew members would serve. Asbestos installed during construction remained in place and in contact with submarine personnel throughout the vessel’s service life.

Non-nuclear submarine work: Before the nuclear era, Electric Boat built diesel-electric submarines that used steam and compressed air systems with the same asbestos insulation standards as surface ships. These conventional submarines represented Electric Boat’s historical asbestos exposure baseline.

Submarine hull compartments: Every compartment in an Electric Boat submarine — engineering spaces, machinery rooms, and technical spaces — was insulated with asbestos-containing materials during construction. Workers in every trade who entered these compartments during construction were exposed to asbestos from the installation work performed throughout the hull.

VA Claims and Legal Options — Electric Boat / General Dynamics Workers

Navy veterans who served aboard submarines built by Electric Boat, civilian workers employed at Electric Boat’s Groton facility in any construction trade, and workers on General Dynamics Electric Boat contracts who performed asbestos-involved work, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease, may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented duty aboard submarines built at Electric Boat’s Groton facility
  • Civil claims against asbestos product manufacturers whose materials were installed in Electric Boat-built submarines, based on documented asbestos product use and the research documenting asbestos exposure in submarine construction

Key documents:

  • DD-214 or service records — documenting submarine service aboard vessels built by Electric Boat
  • Employment records — Electric Boat / General Dynamics employment at the Groton facility in any trade
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
