USS Moinester (FF-1097), last ship of the Knox class ocean escort frigates, was commissioned at Avondale Shipyard in November 1974 — the forty-sixth and final Knox class ship and the last conventionally-powered ASW frigate of the class to be commissioned. Moinester served in the Atlantic Fleet and was one of the later Knox class ships to be transferred to a foreign navy under military assistance programs, serving in the Turkish Navy after her US Navy service. Moinester’s conventional steam propulsion plant — two Babcock & Wilcox boilers and one Westinghouse geared turbine driving a single controllable pitch propeller — provided propulsion through her service. Commissioned in 1974 using the steam propulsion plant typical of the Knox class, Moinester incorporated asbestos-containing boiler insulation, steam pipe insulation, turbine insulation, and hull construction materials consistent with the Knox class construction specifications of the early 1970s.

USS Moinester Steam Plant Asbestos

Moinester’s two-boiler steam plant incorporated asbestos throughout:

  • Babcock & Wilcox boiler insulation — Moinester’s two Babcock & Wilcox boilers were insulated with asbestos-containing boiler casing insulation and steam drum insulation consistent with early 1970s naval construction specifications. Boilermen working in Moinester’s fireroom accumulated asbestos exposure from the boiler insulation throughout her service
  • High-pressure steam main pipe insulation — the steam mains throughout Moinester’s engineering spaces incorporated asbestos-containing pipe insulation consistent with Knox class early 1970s construction specifications. Engineering ratings in Moinester’s machinery spaces encountered steam main insulation during normal operations and maintenance
  • Westinghouse propulsion turbine insulation — Moinester’s single Westinghouse geared main propulsion turbine incorporated asbestos-containing turbine casing insulation. Machinist’s Mates performing turbine maintenance worked in proximity to asbestos-containing turbine insulation
  • ASROC launcher and magazine construction — Moinester’s ASROC antisubmarine rocket launcher and below-deck magazine were constructed using early 1970s construction specifications incorporating asbestos-containing construction materials

VA Claims for USS Moinester 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. Machinist’s Mates, Boilermen, and crew members who served aboard USS Moinester 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.
