New Mexico class battleships — 3 ships (USS New Mexico BB-40, USS Mississippi BB-41, USS Idaho BB-42, commissioned 1917–1919) — were standard-type dreadnought battleships representing an early step toward the turbo-electric propulsion that became standard for subsequent US Navy battleships. New Mexico class ships were powered by four turbo-electric sets using steam generated by Babcock & Wilcox boilers driving electric motors — a propulsion system that combined steam plant thermal efficiency with electric drive flexibility. These ships served in WWI, the interwar period, and WWII, with USS New Mexico and USS Mississippi participating in Aleutian, Pacific Island, and Western Pacific operations, and USS Idaho participating in the Aleutian Campaign and then the Pacific campaign. As with all naval combatants of their era, New Mexico class ships used asbestos insulation throughout the steam plant and interior construction.

Turbo-Electric Steam Plant and Asbestos

New Mexico 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-containing refractory in firebox construction. Boiler Tender ratings maintaining these boilers worked in the fire rooms in direct proximity to asbestos-insulated boiler surfaces during WWI service, interwar modernizations, and WWII Pacific operations
  • Main steam piping — the main steam distribution piping from boilers to the turbo-electric generator sets used asbestos pipe covering throughout the machinery spaces. Engineering ratings were in proximity to asbestos-insulated steam piping during all underway operations throughout the ships’ lengthy service lives
  • Turbo-electric generator insulation — the large steam turbine generator sets powering the electric propulsion motors used asbestos-containing thermal insulation on turbine casing surfaces in the machinery spaces

Extended Service Life and Accumulated Exposure

New Mexico class ships served from WWI through WWII:

  • The New Mexico class ships served from initial commissioning in 1917–1919 through the end of WWII in 1945 — nearly three decades of service — with crew members across this entire period working in the asbestos-insulated engineering spaces and in the asbestos-containing interior construction of these long-serving battleships

VA Claims for New Mexico 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 New Mexico 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.
