Gearing-Class destroyer — Class Background

Ship-specific service history is not available for this vessel in public records. The class-level information below applies to all ships in her class. Source: Wikipedia — Gearing-Class destroyer

The Gearing class consisted of 98 destroyers built for the U.S. Navy during and after World War II, representing a minor modification of the Allen M. Sumner class with a 14-foot lengthened hull amidships to increase fuel storage and operating range. Though the first ships did not enter service until mid-1945, the class continued operating with successive upgrades through the 1970s, including extensive FRAM modernization conversions in the 1960s that transformed them into anti-submarine warfare platforms. Many surplus Gearing-class destroyers were subsequently transferred to other nations, where they served for many additional years.

Asbestos Materials in this Class

The article does not document asbestos use in the Gearing-class. Standard pre-1980 U.S. Navy construction included asbestos in pipe lagging, boiler insulation, gaskets, and habitability spaces.

Navy Ratings Most Exposed to Asbestos Aboard John A. Bole

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.
