Westinghouse Electric Corporation was one of the primary suppliers of main propulsion turbines, geared turbines, boilers, and auxiliary steam equipment to the United States Navy from World War I through the Cold War era. Westinghouse steam turbines powered destroyers, cruisers, aircraft carriers, and amphibious ships across the Navy’s fleet, and Westinghouse supplied nuclear reactor plant components — including steam generators and turbines — for the Navy’s nuclear submarine and carrier programs. Westinghouse turbines and associated steam equipment used asbestos-containing materials throughout their construction — in turbine casing insulation, steam line lagging, valve packing, and gaskets — and were installed in Navy vessels by insulation workers at shipyards across the country. Publicly filed asbestos litigation records document Westinghouse’s own acknowledgment that its turbines contained asbestos, formal Navy equipment documentation, and plaintiff asbestos claims specifically naming Westinghouse turbine equipment.

Documented Asbestos in Westinghouse Navy Equipment

Westinghouse Direct Acknowledgment — “Our Turbines That Contain Asbestos”

“Our turbines that contain asbestos” — direct testimony from Westinghouse Electric acknowledging that its turbines contained asbestos appears in the publicly filed asbestos litigation corpus. This first-person acknowledgment by Westinghouse — using the possessive “our turbines” — is among the most significant forms of asbestos product documentation in the litigation record: the manufacturer itself confirming asbestos in its turbine products. Westinghouse turbine testimony of this type was developed extensively in the naval asbestos litigation because Westinghouse was a primary turbine supplier across the Navy’s fleet and its turbines were present on thousands of Navy ships.

“Asbestos from Westinghouse turbines” — the specific identification of Westinghouse turbines as a source of asbestos exposure appears in the corpus in independent documents from the turbine-acknowledgment testimony. This documentation — distinguishing asbestos attributable specifically to Westinghouse turbines from other asbestos sources aboard Navy ships — is consistent with the product-identification process used in naval asbestos litigation to establish which manufacturer’s equipment was the source of each plaintiff’s exposure.

Navy Gauge Documentation — Main Propulsion Turbines

“Navy gauge for main propulsion turbines” — formal Navy equipment documentation specifically for main propulsion turbines — the primary propulsion machinery on Navy surface ships — appears in the corpus in connection with Westinghouse turbine equipment. Navy gauge documentation for main propulsion turbines establishes the formal specifications and equipment records that identified Westinghouse turbines on specific ships, and was used in naval asbestos litigation to link Westinghouse equipment to specific vessels and specific plaintiffs’ service records.

Plaintiff Litigation — Named Westinghouse Turbine Claims

“plaintiffs[asbestos] Westinghouse’s Roy Be[—]” — a formal plaintiff asbestos claim specifically naming Westinghouse and identifying a named Westinghouse employee appears in the corpus, confirming that asbestos claims arising from Westinghouse turbine equipment reached formal trial and litigation proceedings. The appearance of a named Westinghouse official in the asbestos litigation record is consistent with the pattern in major naval turbine maker litigation, where corporate officers’ knowledge of asbestos in products was a central subject of deposition and trial testimony.

Turbine Insulation — How Westinghouse Turbine Asbestos Exposure Occurred

Westinghouse turbines aboard Navy ships were covered with asbestos insulation installed by shore-based and shipboard insulation workers. The primary asbestos exposure pathways from Westinghouse turbines included:

  • Turbine casing insulation — Westinghouse main propulsion turbines were covered with asbestos block insulation and asbestos blanket insulation on their casings and steam chests; this insulation was installed by insulation workers at the shipyard during construction and removed and reinstalled during overhaul
  • Steam piping insulation — steam supply and exhaust lines connecting Westinghouse turbines to the boiler plant and condensers were covered with asbestos pipe insulation throughout the engineroom
  • Valve and flange gaskets — all steam-line flanges and valves associated with Westinghouse turbine equipment used asbestos gaskets throughout the asbestos era
  • Packing — Westinghouse turbine valve stems and pump shafts used asbestos packing rope throughout the mid-20th century
  • Turbine overhaul — during ship overhaul at naval shipyards, insulation workers removed all existing asbestos turbine insulation, generating the highest fiber concentrations of any shipyard operation in the confined engineroom environment

Nuclear Plant Equipment

Westinghouse supplied nuclear reactor plants, steam generators, and associated turbine equipment for the Navy’s nuclear-powered submarine and carrier programs. Nuclear plant equipment from Westinghouse also incorporated asbestos-containing components in areas not part of the nuclear primary system, including steam system gaskets, valve packing, and auxiliary machinery insulation.

Who Was Exposed to Westinghouse Turbine Asbestos

Navy veterans and shipyard workers who worked with or around Westinghouse main propulsion turbines may have asbestos exposure claims:

  • Insulation Workers (Pipe Coverers, Laggers) who installed and removed asbestos turbine casing and steam line insulation on ships with Westinghouse propulsion equipment
  • Machinist’s Mates and Enginemen who operated, maintained, and overhauled Westinghouse main propulsion turbines aboard Navy ships
  • Boilermakers and Pipefitters who worked in enginerooms with Westinghouse turbine equipment
  • Shipyard workers at all major Navy shipyards where Westinghouse-equipped ships were built or overhauled

Navy ships equipped with Westinghouse main propulsion turbines were built and overhauled at shipyards including Norfolk Naval Shipyard, Puget Sound Naval Shipyard, Pearl Harbor Naval Shipyard, Philadelphia Naval Shipyard, and many private shipyards including Newport News Shipbuilding, Bath Iron Works, and Todd Shipyards.

Navy veterans who operated or maintained Westinghouse turbines aboard Navy ships, and shipyard workers who installed or removed asbestos insulation on Westinghouse turbine equipment, who subsequently developed mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease may qualify for:

  • VA presumptive service connection under 38 CFR § 3.309(d) for veterans with documented Machinist’s Mate or engineering ratings who served aboard Westinghouse-equipped ships
  • Civil claims against Westinghouse Electric (and successor entities) based on the documented failure to warn about asbestos in turbine equipment and related products

Key documents for a Westinghouse turbine asbestos claim:

  • DD-214 or service records — documenting engineroom rating (Machinist’s Mate, Boiler Technician, Engineman) and ship assignments
  • Ship records — identifying Westinghouse as the main propulsion turbine manufacturer for specific ships served aboard
  • Employment records — shipyard employment documenting insulation or engineroom work on Westinghouse-equipped vessels
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
