The Philadelphia Naval Shipyard at League Island built, repaired, and overhauled Navy ships for more than a century before it closed in the 1990s. Asbestos insulation was standard aboard Navy vessels for much of the twentieth century. The yard’s shipfitters, boilermakers, pipefitters, and insulators worked surrounded by it, often in cramped, poorly ventilated spaces below decks. For many Philadelphia families, the yard is where an asbestos exposure history begins.
History of the Philadelphia Navy Yard on the Delaware River
Naval shipbuilding in Philadelphia goes back to the early years of the country, and the League Island yard in South Philadelphia carried that work through the twentieth century. During World War II, the workforce grew into the tens of thousands as the yard built and repaired warships around the clock. After the war, the yard’s mission shifted toward repair, conversion, and modernization, including major aircraft carrier overhauls that continued into the early 1990s. A federal base closure decision ended most of the yard’s work, and the shipyard shut down later that decade.
That long overhaul era matters. Exposure at the yard did not end with wartime construction. It continued for decades, every time an older ship came in and its insulation came out.
Why Navy Ships Contained So Much Asbestos
Fire is one of the greatest dangers at sea, and asbestos was the Navy’s answer to it for generations. Insulation covered boilers, steam piping, turbines, and machinery throughout engineering spaces. Asbestos-containing materials also appeared in bulkheads, gaskets, valve packing, and deck coverings. A ship packed all of it into enclosed steel compartments, where dust had nowhere to go except into the air that crews and yard workers breathed.
Shipyard Trades With the Highest Asbestos Exposure
Insulators cut, mixed, and fitted asbestos insulation by hand. Shipfitters, boilermakers, and pipefitters worked constantly on and around insulated systems. Machinists, electricians, welders, riggers, and painters shared the same compartments and the same air, because below decks, there was no such thing as someone else’s dust. A trade-by-trade breakdown is available for jobs with asbestos exposure.
Ship Overhauls and Asbestos Removal at League Island
New construction meant installing asbestos. Overhaul meant tearing it out. Stripping old, brittle lagging from boilers and steam lines filled engineering spaces with dust, and this was routine work at League Island for decades. Many yard workers diagnosed in recent years spent their careers not building ships but removing and replacing what earlier generations had installed.
Asbestos Claims for Civilian Shipyard Workers and Navy Veterans
Most of the yard’s workforce was civilian. Civilian workers’ claims generally proceed against the companies that manufactured and supplied the asbestos products used aboard the ships, along with asbestos bankruptcy trust claims where applicable. As federal employees, some workers may also have options through the federal workers’ compensation system. Navy veterans who served aboard the ships have similar civil options plus a separate path through VA benefits, covered in mesothelioma claims for veterans. Many Philadelphia families have both histories in one household.
Mesothelioma Latency: Why Diagnoses Come Decades Later
Asbestos exposure is the primary cause of mesothelioma, and asbestos-related diseases often take decades to appear, according to the National Cancer Institute (NCI asbestos fact sheet). A worker who left the yard when it closed or retired long before may only now be receiving a diagnosis. This is general medical background, not medical advice.
Proving Philadelphia Naval Shipyard Asbestos Exposure
The Philadelphia Naval Shipyard has an extensive record in asbestos litigation. Ship records, yard employment records, and years of testimony help identify what was installed, what was removed, and who did the work. A family’s knowledge of the worker’s name, trade, and time at the yard is often a strong starting point. That existing record, part of the larger map of Pennsylvania asbestos exposure sites, can help fill in the details. Spouses and family members who washed yard work clothes may have their own claim path as well, described at asbestos exposure from washing clothes.
Because the yard was a federal facility, civilian employment can often be confirmed through federal personnel records, union records, and Social Security earnings statements.
Pennsylvania Asbestos Lawsuit Deadlines and Wrongful Death Claims
Pennsylvania law sets time limits for filing asbestos claims, and those deadlines can be shorter than families expect. When a worker has already passed away, surviving family members may still be able to bring wrongful death and survival claims, so a late diagnosis or a recent loss does not necessarily close the door. Philadelphia courts have run a dedicated asbestos program for decades, and Michael Schafle is counsel in that program.
