Did you serve aboard the USS Isherwood? This destroyer carried asbestos in nearly every compartment. Here is where it was, and who is responsible. The USS Isherwood, hull number DD-520, was a destroyer, built by Bethlehem Shipbuilding Co. and commissioned in 1943. She served through WWII Atlantic Theater, WWII Pacific Theater, and Cold War Mediterranean. Public naval references list this equipment aboard the USS Isherwood, DD-520 — 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 Isherwood from makers such as Babcock and Wilcox, General Electric, Westinghouse, and Worthington allegedly contained asbestos. If you served aboard the USS Isherwood 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 Isherwood (DD-520) is a fletcher-class destroyer in the U.S. asbestos litigation record. The equipment manifest below is a class-pattern reference assembled from manufacturer and machinery entries documented across 21 sister ships of the same class. Ship-specific BUSHIPS documentation for USS Isherwood (DD-520) herself has not yet been published; this pattern reflects what was standard for vessels of this class.

Navy Ratings Most Exposed to Asbestos Aboard Isherwood

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 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.
