Tennessee class battleships — 2 ships (USS Tennessee BB-43 and USS California BB-44, commissioned 1919–1921) — were the culmination of the standard-type dreadnought battleship design series, incorporating improved turbo-electric propulsion. Both Tennessee class ships were present at Pearl Harbor on December 7, 1941: USS Tennessee was damaged but escaped sinking, and USS California was hit by two torpedoes and bombs and sank at her moorings — both were refloated, thoroughly rebuilt, and returned to Pacific service in 1943–1944. After their extensive modernization, both ships served through the entire Pacific campaign in shore bombardment and fire support roles. The ships’ turbo-electric steam plants and the extensive asbestos-containing construction in their original commissioning and wartime modernization created asbestos exposure for crew members throughout their service.

Turbo-Electric Steam Plant and Asbestos

Tennessee class battleships used turbo-electric propulsion with asbestos throughout:

  • Main boiler insulation — the Babcock & Wilcox boilers used asbestos block insulation on boiler casings and asbestos refractory in firebox construction. Boiler Tender ratings maintaining these boilers worked in the fire rooms in direct proximity to asbestos-insulated boiler surfaces during interwar service and WWII Pacific operations
  • Main steam piping — the steam distribution piping from boilers to turbo-electric generator sets used asbestos pipe covering throughout the machinery spaces. Engineering ratings were in continuous proximity to asbestos-insulated steam piping throughout underway operations
  • Wartime modernization construction — the extensive 1943 modernization of Tennessee class ships at Puget Sound Naval Shipyard added new construction and updated systems using WWII-era construction materials including asbestos-containing pipe insulation, asbestos floor tile, and other asbestos-containing materials in the modernized ship sections

Pearl Harbor and Pacific Service

Tennessee class ships served from WWI commissioning through Pacific campaign:

  • Both Tennessee class ships served from their 1919–1921 commissioning through the end of WWII — including the Pearl Harbor attack, subsequent repairs and modernization, and the entire later Pacific campaign — with crew members across this extended service period working in the asbestos-insulated engineering spaces and interior construction

VA Claims for Tennessee Class Veterans

VA presumptive service connection under 38 CFR § 3.309(d) covers asbestos exposure aboard Navy battleships. Engineering ratings and crew members who served aboard Tennessee class battleships 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.
