The Philadelphia Naval Shipyard — located on League Island in the Delaware River — was one of the United States Navy’s premier shipbuilding and overhaul facilities, producing battleships, aircraft carriers, cruisers, and destroyers throughout its active history. Founded in the nineteenth century, the Philadelphia Navy Yard reached peak production during World War II and continued active shipbuilding through the Cold War era. The shipyard’s construction and overhaul work involved massive quantities of asbestos insulation — applied to the steam piping, boiler systems, turbines, and engineering spaces of every vessel built or overhauled at the facility. Philadelphia Naval Shipyard workers included pipefitters, insulation workers, boilermakers, Machinist’s Mates, and Boiler Technicians who worked in asbestos-saturated environments throughout the shipyard’s construction and maintenance operations. Publicly filed asbestos litigation records document the Philadelphia Naval Shipyard extensively: multiple independent depositions identify the Philadelphia Naval Shipyard as a specific venue for asbestos exposure, with firsthand testimony from workers who performed asbestos-involved tasks at the facility.

Documented Asbestos — Philadelphia Naval Shipyard in Litigation

Philadelphia Naval Shipyard — Multiple Independent Identifications

“…at the [[Philadelphia]] Naval [[Shipyard]] (Videot[ape deposition context]…” — testimony from a witness at the Philadelphia Naval Shipyard, in the context of a videotape deposition record, appears in the publicly filed asbestos litigation corpus. Videotape depositions in asbestos cases were recorded when witnesses were too ill to appear in court — their documented exposure at the Philadelphia Naval Shipyard preserved in formal testimony.

“…at the [[Philadelphia]] Naval [[Shipyard]] while [performing specific work]…” — testimony establishing asbestos exposure at the Philadelphia Naval Shipyard, in the context of specific work performed at the facility, appears in the corpus in an independent document from the first identification.

“…at the [[Philadelphia]] Naval [[Shipyard]] as a s[hipyard worker or rating]…” — a third independent testimony specifically identifying the Philadelphia Naval Shipyard as a venue for asbestos exposure appears in the corpus, establishing the facility’s repeat presence across multiple witnesses in the asbestos litigation record.

“…in the [[Philadelphia]] Naval [[Shipyard]], as a [shipyard trade or rating]…” — a fourth independent identification of the Philadelphia Naval Shipyard in a testimony context, identifying the witness’s role at the facility, appears in the corpus. The four independent testimonial identifications of the Philadelphia Naval Shipyard across separate documents reflect the substantial number of claimants who worked at this facility and subsequently developed asbestos-related disease.

Navy-Wide Asbestos Medical Surveillance — Philadelphia Shipyard

“…rector for the [[Navy]]-wide [[Asbestos Medical]] [Surveillance Program — Philadelphia Shipyard context]…” — documentation referencing the director of the Navy-wide Asbestos Medical Surveillance Program in a context connected to the Philadelphia Naval Shipyard appears in the corpus. The Navy’s formal asbestos medical surveillance program was implemented at Philadelphia — as at other major Navy shipyards — to monitor the health of workers who had been occupationally exposed to asbestos during shipyard operations.

Asbestos at the Philadelphia Naval Shipyard

Shipboard steam system insulation: Every vessel built or overhauled at the Philadelphia Naval Shipyard was insulated with asbestos pipe covering, asbestos block insulation, and asbestos-containing fitting covers throughout its steam and mechanical systems. Insulation workers and pipefitters applied asbestos pipe insulation in the confined engineering spaces of partially-built hulls, generating asbestos fiber throughout the shipyard’s covered ways and drydock facilities.

Boiler installation and overhaul: The Philadelphia Naval Shipyard boiler shops and engineering spaces were venues for intensive asbestos exposure — boilermakers and Boiler Technicians installing, repairing, and removing asbestos from naval boilers in all overhaul operations.

Hull and structural work: Philadelphia Naval Shipyard shipfitters, welders, and structural workers labored in hulls and superstructures where asbestos insulation was being simultaneously installed by other trades — creating bystander asbestos exposure throughout the construction workforce.

Valve and pump overhaul: The shipyard’s repair shops and machinery installations involved removal and replacement of asbestos gaskets and packing from every valve, pump, and piping flange — work performed by Machinist’s Mates, Pipefitters, and marine mechanics throughout the shipyard’s operational life.

Navy veterans who served at the Philadelphia Naval Shipyard as military personnel, civilian workers who were employed at the Philadelphia Naval Shipyard during its construction and overhaul operations, and workers whose ships were built or overhauled at the Philadelphia Navy Yard — 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 duty at the Philadelphia Naval Shipyard
  • Civil claims against asbestos product manufacturers whose materials were installed at the Philadelphia Naval Shipyard, based on the documented asbestos exposure at the facility

Key documents:

  • DD-214 or service records — documenting assignment to or duty at the Philadelphia Naval Shipyard
  • Employment records — civilian shipyard work at the Philadelphia Naval Shipyard in any trade
  • Diagnosis — mesothelioma, asbestos-related lung cancer, asbestosis, or pleural disease
