The Oregon City class and Saint Paul class heavy cruisers were postwar completions and near-sisterships of the Baltimore class heavy cruiser design, commissioned in the immediate postwar period and serving the US Navy as fleet cruisers through the Korean War and Cold War eras. Ships including USS Saint Paul (CA-73), USS Bremerton (CA-130), USS Rochester (CA-124), and related vessels served in Far East and Mediterranean fleet operations through the 1960s-1970s. Built with WWII-era construction standards, these heavy cruisers contained extensive asbestos insulation throughout their engineering spaces and interior structure.

High-Pressure Steam Plant and Asbestos

Oregon City and Saint Paul class heavy cruisers used high-pressure, high-temperature steam plants with multiple boilers and propulsion turbine sets:

  • Fireroom boiler insulation — the main propulsion boilers in heavy cruiser firerooms used massive quantities of asbestos insulation on boiler casing, superheater headers, steam drum casing, and boiler setting materials. Boiler Technicians (BTs) assigned to fireroom watches stood in the boiler room environment with asbestos-insulated boilers as the dominant surface in the compartment
  • Main steam piping — high-pressure superheated main steam piping from firerooms to engine rooms used asbestos pipe covering in multiple layers, with asbestos blanket insulation over expansion joints and at valve bodies throughout the main steam system
  • Engine room turbine casings — main propulsion turbine casings on two or four propulsion shafts had asbestos insulation on turbine external casings and on exhaust steam transition ducting
  • Auxiliary steam systems — ship service steam for hotel loads throughout the heavy cruiser used asbestos-insulated auxiliary steam distribution piping throughout the vessel

Korean War and Cold War Operations

Heavy cruisers assigned to Far East forces during the Korean War and Cold War sustained continuous engineering plant operation during extended deployments:

  • Engineering ratings aboard CA-class heavy cruisers during Korean War gunfire support missions stood continuous watch rotations in firerooms and engine rooms during sustained high-power operations off the Korean peninsula
  • Cold War deployments to the Western Pacific (WestPac) and Mediterranean (MedCruise) involved extended underway periods with continuous steam plant operation in asbestos-insulated engineering spaces

Interior Structural Asbestos

Beyond engineering spaces, WWII-era heavy cruiser construction used asbestos-containing materials throughout the interior:

  • Asbestos deck tile in crew habitability spaces, officer country, and administrative spaces throughout the ship
  • Asbestos ceiling and overhead materials in crew berthing and working spaces
  • Asbestos-insulated steam heating serving the ship’s extensive crew habitability areas

VA Claims for CA Heavy Cruiser Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard Navy surface combatants. Engineering ratings who served in fireroom and engine room billets aboard Oregon City and Saint Paul class heavy cruisers during the Korean War and Cold War and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may qualify for VA disability benefits.

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.
