Evarts class destroyer escorts — 97 ships (DE-5 through DE-262 series, commissioned 1943–1944) — were the first US Navy destroyer escort class to enter WWII service, designed specifically for convoy ASW escort operations in the Battle of the Atlantic and Pacific theater. Evarts class ships were built at Houston Shipbuilding, Western Pipe and Steel, and Bethlehem Steel’s East Boston yard. These ships were powered by General Motors diesel-electric propulsion (four GM 16-278A diesels driving twin electric motors), giving the short-hull design good range for convoy escort duty. As with all Navy vessels of the WWII era, the Evarts class used asbestos-containing materials throughout the ship’s construction, including pipe system insulation, gaskets in diesel and auxiliary machinery systems, and asbestos-containing interior construction materials.

Diesel-Electric Machinery and Asbestos

Evarts class diesel-electric propulsion systems used asbestos-containing materials:

  • Diesel engine exhaust and cooling system insulation — the General Motors diesel generator installations used asbestos-containing pipe insulation on hot exhaust and cooling water piping in the machinery spaces. Enginemen maintaining these diesel systems in the confined machinery spaces of these short-hull escorts worked in proximity to asbestos-insulated piping throughout their shipboard duty
  • Auxiliary machinery gaskets — the auxiliary machinery systems aboard Evarts class ships used asbestos-containing gasket materials in the pipe flange connections throughout the machinery spaces and auxiliary systems
  • Electric propulsion motor spaces — the propulsion motor room and associated electrical distribution spaces used military construction with asbestos-containing materials in the motor room and electrical space construction

WWII Atlantic Convoy Escort Operations

Evarts class ships served in critical Atlantic convoy escort duty:

  • Evarts class ships participated extensively in Atlantic convoy escort operations in the Battle of the Atlantic, with engineering crew members serving watches in the confined, asbestos-insulated machinery spaces of these short-hull escorts throughout the critical mid-war convoy campaign

VA Claims for Evarts Class Veterans

VA evaluates asbestos-related disability claims on a case-by-case basis. Veterans generally need evidence of in-service asbestos exposure, a current asbestos-related diagnosis, and a medical link between them. Engineering ratings and crew members who served aboard Evarts class destroyer escorts and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

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.
