Service History
From the public Wikipedia / DANFS service-history record — source ›
USS Esteem (MSO-438) was an Agile-class minesweeper commissioned in 1955 and homeported at Long Beach, California. She conducted multiple Far East deployments between 1957 and 1962, including patrol and training operations off Vietnam, and served in the Persian Gulf from 1987 to 1990 as part of Operation EARNEST WILL protecting tanker traffic during the Tanker War. Decommissioned in Seattle on 20 September 1991, she was struck from the Naval Vessel Register and ultimately scrapped in 2000.

USS Esteem (MSO-438) is a aggressive-class ocean minesweeper in the U.S. asbestos litigation record. The equipment manifest below is a class-pattern reference assembled from manufacturer and machinery entries documented across 7 sister ships of the same class. Ship-specific BUSHIPS documentation for USS Esteem (MSO-438) herself has not yet been published; this pattern reflects what was standard for vessels of this class.

AsbestosIndex™Product & Manufacturer Reference
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 Esteem
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:
Fireman (FN) — engineering-plant tending across boiler and engine rooms
VA Presumptive Benefits — No Filing Deadline
The U.S. Department of Veterans Affairs recognizes mesothelioma, asbestos-related lung cancer, asbestosis, and pleural disease as conditions presumed to be service-connected for Navy veterans with documented asbestos exposure under 38 CFR § 3.309(d). No statute of limitations applies to VA disability compensation claims.
Available benefits may include monthly disability compensation, Dependency & Indemnity Compensation (DIC) for surviving spouses, priority VA healthcare enrollment, and Special Monthly Compensation for severe cases. Parallel claims against the asbestos bankruptcy trust funds established by the manufacturers of these products do not reduce VA compensation.
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.

Documented Asbestos-Exposure Environments — U.S. Navy Service
Public-domain U.S. Navy photographs illustrating the engineering spaces, ratings, and yard environments where asbestos materials were routinely encountered during normal duty.
All images are public domain (U.S. Government works). Specific photographs depict generic Navy engineering and yard environments — not the named vessel above. Asbestos materials shown or implied include pipe lagging, boiler insulation, steam-line covering, and gasket / packing materials standard on U.S. Navy vessels through the early 1980s.
Esteem MSO-438 — Frequently Asked Questions
