Did you serve aboard the USS John Adams? This submarine carried asbestos in nearly every compartment. Here is where it was, and who is responsible. The USS John Adams, hull number SSBN-620, was a submarine, built by Portsmouth Naval Shipyard and commissioned in 1964. She served through Cold War Atlantic Fleet deterrent patrols, Cold War Pacific Fleet deterrent patrols, and Cold War Atlantic Fleet deterrent patrols. Public naval references list this equipment aboard the USS John Adams, SSBN-620 — insulated and sealed with asbestos. Each shipyard overhaul and major repair meant asbestos insulation was torn out and replaced — peak-exposure work for the yard workers and the crew aboard. Exposure was worst in the engineering spaces, where the snipes worked — but asbestos lined the whole ship, so all hands were exposed. The companies that made the asbestos equipment aboard — not the Navy — are who asbestos claims are brought against. According to asbestos litigation records, the equipment aboard the USS John Adams from makers such as General Electric allegedly contained asbestos. If you served aboard the USS John Adams and were later diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, you may have a legal claim against the companies that made the asbestos products used aboard your ship. This is educational information from an independent publisher — not a law firm — and is not legal advice.

USS John Adams (SSBN-620) is a documented U.S. Navy nuclear-powered ballistic-missile submarine. The equipment reference below was extracted from the publicly-available Wikipedia article on this vessel, which cites the Dictionary of American Naval Fighting Ships (DANFS) — the U.S. Navy’s official ship-history publication maintained by the Naval History and Heritage Command.

VA Disability Claims for Asbestos-Related Disease

The U.S. Department of Veterans Affairs evaluates asbestos claims individually. A veteran generally needs medical evidence of a current asbestos-related disease, service evidence supporting in-service asbestos exposure, and a medical opinion connecting the two. Ship assignments, Navy ratings, and equipment records can help document the exposure history but do not create automatic service connection.

Approved claims may provide monthly disability compensation and related benefits. Survivors may separately qualify for Dependency & Indemnity Compensation when the applicable requirements are met. Civil lawsuits and asbestos-trust claims use different standards; claimants should obtain individualized advice about how the processes interact.

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.
