USS Grand Canyon (AD-28) was a Shenandoah-class destroyer tender and, like every steam-powered warship of her era, carried asbestos insulation, gaskets, and packing throughout her machinery and piping spaces.
The equipment reference below is hull-specific and primary-source — transcribed from the ship’s own Navy construction, equipment-certification, and material-inspection records. It is not a secondary Wikipedia summary; each entry cites the record that ties the manufacturer to this hull.

Source: these 77 equipment-and-manufacturer entries were transcribed from the primary Navy records for USS Grand Canyon (AD-28). Per public litigation records, the machinery aboard ships of this type — boilers, steam turbines, pumps, valves, and their asbestos insulation, gaskets, and packing — allegedly contained asbestos. This is a documentary reference published by an independent publisher; it is not legal advice.
The asbestos-containing products documented on U.S. Navy vessels and at shipyards are catalogued by manufacturer on AsbestosIndex. These records cross-reference which companies supplied which materials and to which facilities.
Navy Ratings Most Exposed to Asbestos Aboard Grand Canyon
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.
