Armstrong Cork Company (later Armstrong World Industries) was one of the major manufacturers of asbestos-containing pipe and block insulation, floor products, and ceiling products used in naval construction and aboard United States Navy ships. Armstrong supplied insulation materials — including asbestos-containing pipe covering, block insulation, and related products — to naval shipyards and the Navy through the 1970s. Armstrong’s own corporate documentation, appearing in the publicly filed asbestos litigation corpus, specifically acknowledges that Armstrong products shipped to the Navy through 1970 contained amosite asbestos. Publicly filed asbestos litigation records document Armstrong with direct corporate testimony about Navy supply relationships, amosite asbestos product documentation through 1970, Boston Navy Shipyard documentation, and formal Armstrong Navy contract evidence.

Documented Asbestos in Armstrong Cork / Armstrong World Industries

Amosite in Armstrong Navy Products Through 1970

“Navy through 1970 contained amosite asbes[tos]…” — formal documentation — attributed to Armstrong — specifically stating that Armstrong products shipped to the Navy through 1970 contained amosite asbestos appears in the publicly filed asbestos litigation corpus across multiple independent documents. Amosite (brown asbestos) is an amphibole asbestos fiber type that is particularly associated with mesothelioma in the epidemiological record. The explicit identification of amosite in Armstrong’s Navy products, and the specific date cutoff of 1970, establishes both the hazardous fiber type present in Armstrong insulation and the period of use.

The 1970 cutoff date is significant — it corresponds to the period when the Navy began formally restricting asbestos-containing materials, and the documentation of amosite-containing Armstrong products through 1970 establishes that this highly carcinogenic fiber type was present in Armstrong Navy insulation throughout the World War II and Cold War periods.

Armstrong Equipment Sold to the U.S. Navy

“Armstrong equipment sold to the U.S. Navy…” — formal documentation of Armstrong equipment (insulation and related products) specifically sold to the United States Navy appears in the corpus. The “equipment” framing — rather than simply “materials” — suggests that Armstrong’s Navy supply relationship encompassed not only loose insulation materials but also formed insulation products, insulation systems, or related equipment supplied to naval accounts.

“United States Navy whom Armstrong expects to[testify about/identify]…” — formal litigation documentation naming the United States Navy as an entity that Armstrong expects to be involved in testimony about its asbestos products, consistent with Armstrong’s status as a major Navy asbestos product supplier facing claims from Navy veterans.

Navy Ships — Armstrong Insulation Use Documented

“Navy ships and how the Navy used asbestos…” — documentation specifically addressing how the Navy used asbestos-containing products — in the Armstrong context — appears in the corpus. Armstrong testimony about the Navy’s asbestos use patterns establishes both the corporate knowledge of asbestos use in naval applications and the scope of Armstrong’s involvement in the naval asbestos supply chain.

“the ship. He may discuss how the Navy str[ipped/removed asbestos from ships]…” — documentation of how the Navy stripped or removed asbestos from ships appears in the corpus in the Armstrong context, consistent with testimony about what happened to Armstrong asbestos insulation during naval ship overhaul operations — when all existing insulation was removed from engineering spaces before overhaul work began.

Boston Navy Shipyard — Armstrong Documentation

“upkeep at Boston Navy Shipyard. I am certai[n]…” — documentation specifically linking Armstrong products to upkeep and maintenance operations at Boston Navy Shipyard appears in the corpus. The specific naming of Boston Navy Shipyard (Charlestown) in the Armstrong asbestos context establishes that Armstrong insulation products were used in naval shipyard maintenance and overhaul operations at this New England yard — in addition to new ship construction.

Armstrong Asbestos Exposure Pathways

Pipe insulation: Armstrong asbestos pipe covering — pre-formed half-round sections for application to steam and hot-water piping — was installed by insulation workers at shipyards during construction and removed during overhaul. Armstrong pipe covering sections containing amosite were cut, fitted, and applied throughout ship engineering spaces.

Block insulation: Armstrong asbestos block insulation was used on irregular surfaces — boiler casings, valve bodies, and fittings — that could not be covered with standard pipe covering. Block insulation installation and removal generated dust containing amosite fibers.

Floor and ceiling products: Armstrong also manufactured asbestos-containing floor tile and ceiling tile that were used in shore-based naval facilities. Building maintenance and renovation at naval installations using Armstrong floor products created asbestos exposure for maintenance workers.

Who Was Exposed to Armstrong Asbestos Products

  • Insulation Workers (Pipe Coverers, Laggers) — HFIAW members who installed and removed Armstrong amosite asbestos insulation throughout naval and private shipyards
  • Engineering ratings (BT, MM) — worked in engineering spaces insulated with Armstrong products throughout the ship’s operational life
  • Shipyard maintenance workers and base facility workers — maintained shore facilities with Armstrong floor and ceiling products

Navy veterans and shipyard workers exposed to Armstrong Cork / Armstrong World Industries asbestos insulation products, 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 engineering ratings who served aboard ships insulated with Armstrong products through 1970
  • Armstrong World Industries bankruptcy trust — Armstrong’s asbestos liabilities were resolved through a 524(g) trust; trust claims may be available for qualifying mesothelioma claimants
  • Civil claims against Armstrong successors based on the documented use of amosite asbestos in Armstrong Navy products through 1970

Key documents:

  • DD-214 or service records — documenting engineering rating and ship assignments through 1970
  • Employment records — shipyard insulation trade work
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
