Liberty & Victory ships (Navy Armed Guard)

MusterLog™ 0

The WWII emergency shipbuilding program turned out thousands of Liberty ships and Victory ships — mass-produced cargo tonnage crewed by the U.S. Merchant Marine and defended by U.S. Navy Armed Guard gun crews. Their oil-fired steam plants were insulated with asbestos throughout the engine and boiler rooms, exposing the merchant engine crews and the Navy gunners who served aboard. Below are the surviving ships we cover.

VA Benefits for Navy Armed Guard Veterans

The Navy Armed Guard were commissioned U.S. Navy personnel, and their WWII sea service is qualifying military service for VA purposes. Armed Guard veterans diagnosed with an asbestos-related disease may qualify for VA disability compensation when the record shows in-service exposure, a current diagnosis, and a medical link between them. (Merchant-crew claims follow a separate maritime path; claims against the makers of the asbestos products used aboard may be available to anyone exposed.)

Diagnosed with mesothelioma after service aboard these ships? Navy Armed Guard veterans — and others who served aboard Liberty and Victory ships — diagnosed with mesothelioma or another asbestos-related disease after exposure aboard may be able to pursue a claim against the makers of the asbestos products used aboard.

Navy Ratings Most Exposed to Asbestos Aboard Liberty & Victory Ships — Armed Guard

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:

Boilerman (BT) — boiler-room operations, refractory work, burner maintenance
Machinist’s Mate (MM) — main propulsion turbines, reduction gears, condensers, pumps
Engineman (EN) — auxiliary diesel and gasoline engines, gland packing
Electrician’s Mate (EM) — cable runs through asbestos-insulated chases, motor-generator sets
Hull Maintenance Technician (HT) / Pipefitter — piping system maintenance, gasket replacement, valve repacking
Damage Controlman (DC) — firefighting equipment, fire-stops, bulkhead penetrations
Fireman (FN) — engineering-plant tending across boiler and engine rooms

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.
