USS Trepang (SSN-674) is a documented U.S. Navy nuclear-powered attack submarine with asbestos-exposure evidence in the public litigation record. The equipment manifest below was assembled from depositions, expert reports, and manufacturer interrogatory responses filed in U.S. asbestos litigation that reference equipment installed aboard this vessel.

Note: this manifest is derived from public asbestos litigation records (depositions, expert reports, manufacturer interrogatories) rather than primary BUSHIPS construction documents. Entries reflect what has been documented or alleged in publicly filed legal records.
Asbestos-Containing Materials Aboard Trepang
U.S. Navy submarines built between the 1930s and 1980s were constructed with extensive asbestos-containing materials throughout machinery spaces, engineering plants, and habitability compartments. The standard ACM categories installed and maintained aboard included:
- Pipe lagging and thermal insulation — main steam, feed-water, fuel-oil, condensate, and saltwater piping throughout machinery spaces.
- Boiler block insulation, refractory brick, and gun-blocks — around the main boilers and burner fronts.
- Asbestos gaskets and braided packing — valves, flanges, pumps, condensers, heat exchangers, and turbine glands.
- Insulation jackets and removable lagging — main propulsion turbines, reduction gears, ship-service turbine generators, and forced-draft blowers.
- Sheet asbestos and Marinite panels — fire-stops, bulkhead insulation, and overhead insulation throughout damage-control zones.
- Vinyl asbestos floor tile (VAT) — passageways, berthing, mess decks, wardroom, and habitable compartments.
- Asbestos rope, wick, and tape — gland-seal applications throughout the engineering plant.
Navy Ratings Most Exposed to Asbestos Aboard Trepang
The U.S. Department of Veterans Affairs and the public asbestos litigation record document that the following Navy ratings worked routinely in spaces where ACM was installed, maintained, ripped out, and replaced:
VA Presumptive Benefits — No Filing Deadline
The U.S. Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions presumed to be service-connected for Navy veterans with documented asbestos exposure under 38 CFR § 3.309(d). No statute of limitations applies to VA disability compensation claims.
Available benefits may include monthly disability compensation, Dependency & Indemnity Compensation (DIC) for surviving spouses, priority VA healthcare enrollment, and Special Monthly Compensation for severe cases. Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products do not reduce VA compensation.
How to file a VA disability claim: VA claims are filed directly with the U.S. Department of Veterans Affairs — not with a law firm. Start at VA.gov › Hazardous Materials Exposure, call 1‑800‑827‑1000, or get free help filing from a Veterans Service Organization: DAV, VFW, or American Legion.
