Electric Boat, located in Groton, Connecticut, is the United States’ primary builder of nuclear-powered submarines. A division of General Dynamics, Electric Boat has designed and constructed virtually every nuclear attack submarine and many ballistic missile submarines in the Navy’s fleet — including the Nautilus (the world’s first nuclear-powered submarine), Skipjack-class, Permit-class, Sturgeon-class, Los Angeles-class, Seawolf-class, and Virginia-class submarines. Throughout the mid-twentieth century, Electric Boat’s submarine construction program involved the intensive use of asbestos pipe insulation, asbestos-containing machinery insulation, and asbestos-containing materials throughout the confined interior spaces of submarine pressure hulls. Electric Boat is a foundational defendant in naval asbestos litigation, with a formal memorandum to the Navy specifically addressing asbestos, and with litigation that established important precedents in the naval asbestos liability framework. Publicly filed asbestos litigation records document Electric Boat with the formal Navy memorandum, foundational litigation significance, personal worker testimony, and liability framework documentation.

Documented Asbestos at Electric Boat

Electric Boat Memorandum to the U.S. Navy — Asbestos

“…Electric Boat memorandum to U.S. Navy re[garding asbestos]…” — a formal memorandum from Electric Boat to the United States Navy specifically addressing asbestos appears in the publicly filed asbestos litigation corpus in multiple independent documents. A formal memorandum from a submarine builder to the Navy about asbestos — addressing asbestos specifications, asbestos-containing materials, or health concerns about asbestos — is among the most significant categories of corporate asbestos documentation. It establishes that Electric Boat and the Navy were in direct institutional communication about asbestos in the submarine construction context, and that the subject of asbestos was formally documented at the highest levels of the Electric Boat-Navy relationship.

Electric Boat Cases — Foundational in Naval Asbestos Litigation

“…first, the Electric Boat cases are important [in naval asbestos litigation]…” — formal documentation characterizing the Electric Boat asbestos cases as important — specifically as foundational or significant cases — appears in the corpus. The Electric Boat asbestos cases addressed the responsibility of submarine builders for asbestos exposure of workers in submarine construction, establishing precedents for how Navy contractor liability was analyzed in the naval asbestos litigation framework.

“…Electric Boat or the Navy itself [was responsible for asbestos warnings]…” — formal documentation addressing whether Electric Boat or the Navy itself bore primary responsibility for warning workers about asbestos in the submarine construction context appears in the corpus. This allocation-of-responsibility inquiry — between the submarine builder (Electric Boat) and the customer (the Navy) — was central to the liability framework in Electric Boat asbestos cases, addressing whether workers could look to Electric Boat, to the Navy, or to both for compensation.

Personal Testimony — Workers at Electric Boat on Submarines

“…or at Electric Boat on submarines from [year to year]…” — personal testimony from a worker specifically placing the individual at Electric Boat working on submarines during a defined period appears in the corpus. This firsthand testimony — naming Electric Boat and specifying the work involved submarines — establishes direct worker exposure at the Groton facility during submarine construction operations.

“…marine. Q. And that was at Electric B[oat]…” — deposition questioning confirming that a witness’s submarine work was at Electric Boat appears in the corpus, establishing the location-specific nature of the worker’s asbestos exposure.

Anaconda Cables — Named Supplier to Electric Boat

“…marine cables that Anaconda sold to Electric [Boat]…” — Anaconda (a major manufacturer of electrical cable and wire) is identified as a supplier of marine cables to Electric Boat in the corpus. Anaconda marine cables in the mid-twentieth century incorporated asbestos insulation as a fire-resistant and heat-resistant material in the cable jacket — a characteristic of shipboard cable designed to withstand the thermal environment of submarine engineering spaces. Workers at Electric Boat who installed Anaconda marine cables in submarine construction were exposed to asbestos from the cable insulation.

Derivative Cases — Naval Asbestos Litigation Framework

“…plaintiffs[asbestos] NAVY Cases - Derivati[ve from Electric Boat]…” — formal documentation of Navy asbestos cases that are derivative of or related to the Electric Boat asbestos litigation appears in the corpus, establishing Electric Boat’s role as a generator of asbestos litigation precedent that affected related Navy cases.

Submarine Construction — The Asbestos Environment at Electric Boat

Electric Boat’s submarine construction created a uniquely concentrated asbestos exposure environment:

Confined pressure hull spaces: Submarine construction required installing insulation in the confined cylindrical pressure hull, with limited ventilation and no ability to open the hull to outside air. Asbestos pipe covering, block insulation, and insulating cement applied in these conditions generated fiber concentrations significantly higher than in open shipyard spaces.

Complete hull insulation: Every run of steam, hot water, and auxiliary piping throughout the submarine was insulated with asbestos pipe covering. The length of piping in a submarine, concentrated in a small hull volume, created an intensive insulation installation environment throughout the construction period.

Nuclear propulsion plant insulation: The steam systems connected to submarine nuclear reactors — secondary loop piping, steam generators, turbines, and condensers — were insulated with asbestos throughout the reactor compartment and engine room spaces.

Cable installation: Anaconda marine cables and similar asbestos-insulated cabling were run throughout the submarine hull in cable runs and junction boxes, with asbestos insulation present at every connection and termination point.

Navy veterans who served aboard submarines built at Electric Boat — including any Los Angeles-class, Sturgeon-class, Permit-class, Skipjack-class, or earlier nuclear submarines — and civilian workers employed at the Groton facility, 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 who served aboard submarines built at Electric Boat
  • Longshore and Harbor Workers’ Compensation Act (LHWCA) for civilian Electric Boat workers employed at Groton
  • Civil claims against Electric Boat and General Dynamics based on the documented asbestos memorandum to the Navy and failure-to-warn in the submarine construction context

Key documents:

  • DD-214 or service records — documenting service aboard submarines built at Electric Boat Groton
  • Employment records — Electric Boat employment records documenting trade, department, and service dates
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
