Babcock & Wilcox Company (B&W) was one of the primary manufacturers of marine boilers for the United States Navy from World War I through the Cold War era, supplying the high-pressure steam boilers that powered Navy destroyers, cruisers, battleships, and aircraft carriers. B&W also became a primary supplier of nuclear reactor plants for the Navy’s nuclear-powered submarine program — the company developed the reactor plants for the USS Nautilus (SSN-571), the world’s first nuclear-powered submarine, and continued as a central contractor in the Naval Reactors program. B&W boilers and reactor plants incorporated asbestos-containing materials throughout their construction — in boiler casing insulation, steam drum insulation, superheater insulation, and the vast network of steam piping connecting B&W boilers to ship propulsion turbines. Publicly filed asbestos litigation records document B&W’s direct acknowledgment that its Navy boilers contained asbestos, a 1943 wartime memorandum specifically concerning B&W boilers, and formal B&W boiler shipment records to the Navy.

Documented Asbestos in Babcock & Wilcox Navy Equipment

Direct Testimony — “Babcock and Wilcox Made Boilers in the Navy”

“Babcock and Wilcox made boilers in the Navy” — direct testimony identifying Babcock and Wilcox as the manufacturer of Navy boilers appears in the publicly filed asbestos litigation corpus. This testimony — establishing B&W’s role as a primary Navy boiler manufacturer — appears in the context of asbestos exposure litigation, where identifying the manufacturer of the specific boiler equipment aboard a ship was the central product-identification task. B&W boiler testimony of this type was developed extensively across the naval asbestos litigation because B&W boilers were present on destroyers, cruisers, and other surface combatants throughout the World War II and Cold War fleets.

1943 Wartime Memorandum — Contemporaneous Documentation

“12/17/43 Memo B&W boilers” — a formally dated memorandum from December 17, 1943 specifically addressing Babcock & Wilcox boilers appears in the publicly filed asbestos litigation corpus. A 1943 document specifically concerning B&W boilers in the context of the naval asbestos litigation record is one of the most significant forms of contemporaneous documentation — establishing that B&W boiler conditions, including asbestos-related conditions, were the subject of formal written communication during the height of World War II Navy boiler production. Documents from this era typically concern boiler installation specifications, asbestos insulation requirements, or early awareness of asbestos-related health concerns.

Consolidated Safety Valve — Associated Equipment Documentation

“B&W boiler, Consolidated Safety Valve Co.” — the specific pairing of a Babcock & Wilcox boiler with Consolidated Safety Valve Company equipment appears in the corpus, establishing that B&W boiler installations were documented with associated valve and fitting manufacturers. This type of system-level documentation — identifying not just the boiler manufacturer but also the valve and safety equipment manufacturers paired with B&W boilers on specific ships — is used in naval asbestos litigation to identify all manufacturers whose products contributed to asbestos exposure in the boiler room environment.

Shipment Documentation — B&W Boilers to the Navy

“Shipped CVIS, 32-40 Main boiler — asbestos” — formal shipment documentation identifying a main boiler shipped to the Navy, associated with asbestos-containing materials, appears in the corpus in connection with Babcock & Wilcox boiler equipment. Shipment records of this type — identifying specific boiler units with associated asbestos specifications or asbestos-containing components — establish the chain of custody from the B&W manufacturing plant to the Navy shipyard where the boiler was installed, and confirm that asbestos-containing materials were part of the B&W boiler assembly.

How Babcock & Wilcox Boiler Asbestos Exposure Occurred

B&W marine boilers generated asbestos exposure through the most intensive pathways in the Navy shipboard environment:

Boiler casing and drum insulation:

  • B&W boilers were covered with massive amounts of asbestos insulation — asbestos block insulation on the boiler casings, asbestos cement in the joints, and asbestos blanket on the steam drums and superheaters; this insulation was installed by insulation workers at the shipyard during construction and replaced during each overhaul cycle
  • The boiler room environment during insulation removal generated the highest asbestos fiber concentrations found anywhere in the shipboard environment

Steam system connections:

  • All steam drum flanges, steam line connections, and safety valve connections on B&W boilers used asbestos gaskets throughout the relevant era
  • Steam supply lines from B&W boilers to main propulsion turbines were covered with asbestos pipe insulation throughout the engineroom

Boiler brick and refractory:

  • B&W boiler fireboxes used asbestos-containing refractory materials in addition to standard brick, particularly in high-temperature areas adjacent to the burner assembly

Nuclear reactor plants:

  • B&W supplied the reactor plants for many of the Navy’s nuclear-powered attack submarines; these reactor plants used asbestos-containing materials in steam generator and auxiliary system connections outside the primary reactor system

Who Was Exposed to Babcock & Wilcox Boiler Asbestos

Navy veterans and shipyard workers who worked with or around B&W boilers may have asbestos exposure claims:

  • Insulation Workers (Pipe Coverers, Laggers) who installed and removed asbestos boiler casing and steam drum insulation on B&W-equipped ships
  • Boiler Technicians (BT) and Boilermen (B) who operated, maintained, and repaired B&W boilers aboard Navy ships
  • Machinist’s Mates (MM) who worked in enginerooms with B&W boilers
  • Pipefitters and Boilermakers at naval and private shipyards who worked in boiler rooms with B&W equipment during construction and overhaul
  • Shipyard workers at all major Navy shipyards who built or overhauled ships with B&W boiler installations

B&W boilers were installed on destroyers built at Bath Iron Works, Bethlehem Steel Shipyards, Federal Shipbuilding, and other major yards; and on cruisers, battleships, and carriers built at Newport News Shipbuilding, Brooklyn Navy Yard, Philadelphia Naval Shipyard, and other primary capital ship yards.

Navy veterans who operated or maintained B&W boilers aboard Navy ships, and shipyard workers who installed or removed asbestos insulation on B&W boiler 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 Boiler Technician or engineering ratings who served aboard B&W-equipped ships
  • Civil claims against Babcock & Wilcox (and successor entities) based on documented failure to warn about asbestos in boiler products, as established in the publicly filed litigation record

Key documents for a B&W boiler asbestos claim:

  • DD-214 or service records — documenting BT, MM, or other engineering rating and ship assignments
  • Ship records — identifying B&W as the boiler manufacturer for specific ships served aboard
  • Employment records — shipyard employment documenting insulation or boilermaker work on B&W-equipped vessels
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
