Commencement Bay class escort carriers — 19 ships (CVE-105 through CVE-127, commissioned 1944–1946) — were purpose-built on a new standardized hull (S4-S2-BB3) that was larger and more capable than the C3 cargo hull CVE conversions. Built at Todd-Pacific Shipyards (Seattle, Washington) and Todd Shipbuilding (Tacoma, Washington), Commencement Bay class ships were powered by two Combustion Engineering boilers driving Allis-Chalmers turbines for 19,000 shaft horsepower — a simplified steam plant suitable for escort carrier requirements. Many Commencement Bay class ships were completed too late for WWII combat and served through the early Cold War era in ASW carrier, utility carrier (CVU), and helicopter carrier roles before reserve fleet placement.

WWII-Era Steam Plant and Asbestos

Commencement Bay class carriers used simplified steam propulsion with asbestos throughout:

  • Main boiler insulation — the two Combustion Engineering boilers aboard Commencement Bay class ships used asbestos block insulation on boiler casings and asbestos-containing refractory in firebox construction from the original mid-1940s construction. Boiler Technicians maintaining these boilers worked in proximity to asbestos-insulated boiler surfaces throughout the ship’s service life
  • Main steam system pipe insulation — the main steam piping from two boilers to the propulsion turbines used asbestos pipe covering throughout the engineering spaces from the original 1944–1946 construction. Engineering ratings in the machinery spaces were in proximity to asbestos-insulated steam piping during the escort carrier’s operations
  • Turbine insulation — the Allis-Chalmers turbines aboard Commencement Bay class ships used asbestos-containing insulation lagging consistent with mid-1940s escort carrier construction

Mid-1940s Interior Construction

Commencement Bay class ships used WWII-era construction materials throughout:

  • The crew berthing, hangar deck, and working spaces throughout these purpose-built escort carrier hulls used mid-1940s construction materials including asbestos deck covering and interior construction consistent with the wartime escort carrier construction era

Cold War Service Periods

Many Commencement Bay class ships served through the early Cold War:

  • These ships served in various post-WWII roles through the 1950s, with crew members in the early Cold War era serving aboard ships carrying original mid-1940s asbestos construction materials that had been in service for ten to fifteen years by the time Cold War operations began

VA Claims for Commencement Bay 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 Commencement Bay class escort carriers (CVE-105 through CVE-127) and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

Navy Ratings Most Exposed to Asbestos Aboard Commencement Bay Class (CVE)

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.
