Philadelphia Naval Shipyard
Philadelphia Naval Shipyard: 50,000+ Workers Exposed to Asbestos During 195-Year Naval History
Executive Summary
The Philadelphia Naval Shipyard stands as America's first official naval shipyard and one of the nation's most significant sites of occupational[3] asbestos exposure.[4] Operating continuously from 1801 until closure in 1996, this historic facility constructed 53 warships during World War II alone while employing over 47,695 civilian workers at peak production, with total workforce numbers exceeding 60,000 including military personnel.[5] The shipyard's remarkable 195-year operational history encompasses revolutionary achievements in naval engineering, secret Manhattan Project contributions, and the construction of legendary Iowa-class battleships including the USS New Jersey and USS Wisconsin.
However, this industrial triumph carries a devastating human cost. According to Danziger & De Llano case documentation, more than 50,000 workers at Philadelphia Naval Shipyard experienced significant asbestos exposure during operations spanning from the 1880s through the 1980s. During World War II, when asbestos use reached its peak, workers handled materials containing up to 900 tons of asbestos per vessel without adequate protective equipment or warnings about the deadly health risks they faced daily.[6]
The health consequences have proven catastrophic. Research documented by Mesothelioma Lawyer Center confirms that 86% of ship repair workers developed asbestosis, with shipyard workers experiencing mortality rates from asbestos-related diseases 15 times higher than the general population.[7] Today, 33% of all mesothelioma cases link directly to shipyard exposure, with approximately 1,000 shipyard workers and Navy veterans[8] developing this fatal cancer annually across the United States.[9]
For workers and families affected by Philadelphia Naval Shipyard asbestos exposure, substantial compensation remains available through multiple pathways. Over $30 billion exists in asbestos bankruptcy trust funds from manufacturers who supplied the shipyard, while individual lawsuits have secured verdicts exceeding $7 million for former workers.[10] Navy veterans also qualify for VA disability benefits worth up to $48,539 annually, plus free VA medical care at specialized treatment centers throughout the country. Families should understand that the 42.8-year average latency period for mesothelioma means workers exposed during the 1960s-1980s are only now receiving diagnoses, making immediate legal consultation essential.[11]

What Is the History of Philadelphia Naval Shipyard?
The Philadelphia Naval Shipyard traces its origins to 1776 when the Continental Congress leased waterfront land for naval defense during the Revolutionary War.[12] Joshua Humphreys, appointed as the nation's first Naval Constructor in 1794, designed and built the USS United States, launched May 10, 1797, as the first American warship constructed under the U.S. Constitution. The federal government officially purchased Humphreys' shipyard in 1801, establishing the Southwark Yard as America's first government-owned naval facility.
The shipyard's early achievements established its significance in American naval history. The USS Franklin launched on August 21, 1815, before 50,000 spectators, marking the facility's first major warship. The crowning achievement of this era was the USS Pennsylvania, launched in 1837 after sixteen years of construction, which became the largest sailing warship ever built for America with 136 guns on four decks and a cost of $687,000 (approximately $22 million today).
How Did League Island Transform the Shipyard?
By 1862, the Civil War and ironclad technology rendered the cramped Southwark site obsolete. Philadelphia purchased the 923-acre League Island property for $310,000, presenting it to the Navy for $1 on December 22, 1868. This strategic location at the confluence of the Delaware and Schuylkill rivers served as the shipyard's home for the next 128 years, allowing dramatic expansion that would eventually make Philadelphia one of America's premier naval facilities.[13]
The Naval Aircraft Factory, established July 27, 1917, achieved remarkable speed in construction, with its main assembly building rising in just 110 days. The first H-16 flying boat flew successfully on March 27, 1918, merely 228 days after groundbreaking. By the Armistice, the factory employed 3,640 workers including 890 women, producing 137 H-16 flying boats, 31 F-5L flying boats, and 4 N-1 Davis Gun Carriers.
| "The Philadelphia Naval Shipyard represents a unique case in occupational health history. Workers who built and repaired vessels here faced some of the most intense asbestos exposures documented anywhere in American industry, yet most had no idea of the dangers they encountered daily." |
| — Paul Danziger, Founding Partner, Danziger & De Llano |
What Made Philadelphia Naval Shipyard's World War II Production So Significant?
The shipyard reached its zenith during World War II, expanding from 9,000 peacetime workers to 47,695 civilian employees by 1944, with total employment exceeding 60,000 including military personnel.[14] This massive workforce, one-third women serving as "Rosie the Riveters," constructed 53 warships and repaired 574 vessels while the Naval Aircraft Factory built 500 planes. The facility processed 70,000 Navy recruits through its receiving station while maintaining around-the-clock production schedules.
Philadelphia Naval Shipyard earned distinction as the only facility to build two Iowa-class battleships during World War II. The USS New Jersey (BB-62) launched on December 7, 1942, the first Pearl Harbor anniversary, and commissioned May 23, 1943, eventually becoming the Navy's most decorated battleship with 19 Battle and Campaign stars. Her sister ship USS Wisconsin (BB-64) followed, launching December 7, 1943, and commissioning April 16, 1944. These engineering marvels measured 887 feet 7 inches overall, displaced 57,540 tons fully loaded, and achieved speeds exceeding 33 knots with nine 16-inch guns capable of firing 2,700-pound shells over 23 miles.
What Was the Manhattan Project Connection?
One of the shipyard's most significant yet least-known contributions involved Dr. Philip Abelson's uranium enrichment work for the Manhattan Project. Working at the Naval Laboratory from 1942 to 1945, Abelson developed the liquid thermal diffusion process that separated fissionable uranium-235 from uranium-238. His June 22, 1942, achievement of 9.6% enrichment, later improved to 21%, provided the breakthrough that enabled industrial-scale uranium production.[15]
The Navy authorized construction of a pilot plant at the Naval Boiler and Turbine Laboratory on November 17, 1943, completing it by July 1944 for just $500,000. This Philadelphia prototype enabled construction of the massive S-50 plant at Oak Ridge in an astounding 69 days, ultimately producing nearly 45,000 pounds of enriched uranium by July 1945. According to Dr. Abelson, this technology helped shorten World War II by an estimated seven days.
| ℹ️ Did You Know: Philadelphia Naval Shipyard revolutionized global shipbuilding by becoming the first facility worldwide to employ floating dry docks, allowing workers to inspect and service normally submerged hull areas without constructing expensive permanent dry docks. The yard's 3,500-ton League Island Crane, installed in 1919, was then the world's largest. |
What Asbestos Exposure Did Philadelphia Naval Shipyard Workers Face?
Asbestos use at Philadelphia Naval Shipyard spanned from the 1880s through the 1980s, with peak exposure occurring during World War II when over 50,000 workers handled materials containing up to 900 tons of asbestos per vessel.[16] The Navy classified asbestos as a "critical material" in 1939, mandating its use in military contracts. Philadelphia's wartime construction of 53 ships and repair of 1,792 vessels exposed workers to 298 different asbestos-containing products throughout every ship compartment.
Three asbestos types contaminated the shipyard. Chrysotile (white asbestos) comprised 90-95% of materials, used in insulation, gaskets, and packing. Amosite (brown asbestos), the second most common, appeared in pipe insulation, ceiling tiles, and thermal barriers. Crocidolite (blue asbestos), though less common, proved most deadly in steam engine insulation and spray coatings. While commercial vessels contained up to 10 tons of asbestos, Navy ships held up to 900 tons of asbestos materials, essentially making them floating hazardous waste sites for workers.[17]
Which Occupations Faced the Highest Risk?
Asbestos pervaded every ship system and shipyard building. Ship components included pipe insulation throughout vessels, boiler and turbine wrapping, engine gaskets and valve packing, fireproof doors and walls, deck tiles and adhesives, electrical cable insulation, machinery casings, brake linings, and clutch components. The entire hull often featured asbestos lining, with concentrated exposure in engine rooms, boiler spaces, and sleeping quarters where workers spent extended periods.
Insulation Workers and pipefitters faced the highest exposure, cutting through asbestos-wrapped pipes and installing new insulation that released millions of fibers.[18] Boilermakers maintained steam systems laden with asbestos lagging. Electricians handled asbestos-containing cables and panels. Welders created toxic clouds when cutting through asbestos materials. Machinists, sheet metal workers, and painters encountered contamination throughout their work areas. Even laborers not directly handling asbestos suffered "bystander exposure" from airborne fibers that remained suspended for hours.
| "In our decades of representing shipyard workers, we've observed that the most dangerous exposure often occurred during 'ripout' operations when workers removed old insulation during overhauls. Workers describe clouds of asbestos dust so thick you couldn't see across the compartment. No protective equipment was provided, and workers often ate lunch covered in asbestos dust." |
| — Rod De Llano, Founding Partner, Danziger & De Llano |
How Did Secondary Exposure Affect Families?
Secondary exposure affected families when workers brought contaminated clothing home. Studies show that 11.3% of shipyard workers' wives and 7.6% of sons developed asbestos-related lung damage from household contamination.[19] Family members who never set foot in the shipyard developed serious respiratory diseases simply from laundering work clothes or greeting workers who arrived home covered in asbestos fibers. These secondary exposure cases now represent a significant portion of mesothelioma claims related to Philadelphia Naval Shipyard workers.
| ⚠️ Important for Families: If your spouse, parent, or family member worked at Philadelphia Naval Shipyard between 1940-1990, you may have experienced secondary asbestos exposure. The 42.8-year average latency period means health effects from exposure decades ago may only now be emerging. Contact an experienced mesothelioma attorney for a free case evaluation. |
What Health Statistics Confirm the Occupational Disaster?
The statistics reveal an occupational health catastrophe of unprecedented scale affecting Philadelphia Naval Shipyard workers and their families.[20] During World War II alone, 4.5 million Americans experienced asbestos exposure in shipyards across the nation. Research confirms that 86% of ship repair workers developed asbestosis, including those who never directly handled asbestos materials. Shipyard workers experience mortality rates from asbestosis 15 times higher than the general population.
Italian maritime studies tracking 466 mesothelioma cases from 1993-2018 found shipyard workers' Standardized Mortality Ratio for mesothelioma at 575, nearly six times expected rates. The SMR for asbestosis reached an astounding 2,277, over 22 times normal rates. Lung cancer SMR measured 154, with 22.6% of lung cancer deaths attributed to asbestos exposure. A 1984 Norfolk Naval Shipyard survey found 79% of workers showed lung abnormalities. According to Mesothelioma.net data, Philadelphia-specific exposure rates were likely comparable or worse given the facility's size and operational scope.[21]
| Health Metric | Shipyard Workers | General Population |
|---|---|---|
| Mesothelioma SMR | 575 (5.75x expected) | 100 (baseline) |
| Asbestosis SMR | 2,277 (22.77x expected) | 100 (baseline) |
| Lung Cancer SMR | 154 (1.54x expected) | 100 (baseline) |
| Workers Developing Asbestosis | 86% | <1% |
| Lung Abnormalities (1984 Survey) | 79% | ~5% |
The latency period averaging 42.8 years means workers exposed in the 1960s-1970s are only now developing diseases. Mesothelioma, with median survival of 12 months post-diagnosis, affects 30% of military veterans. The Environmental Working Group estimates 40,000 veterans have died from asbestos-related illnesses, with deaths continuing to mount annually. These statistics represent individual tragedies multiplied thousands of times, as each percentage point represents hundreds of Philadelphia workers who brought home deadly fibers to their families or died decades after believing they had escaped harm.
What Compensation Options Exist for Philadelphia Naval Shipyard Workers?
Affected workers and their families have secured significant legal victories against asbestos manufacturers who supplied Philadelphia Naval Shipyard.[22] Edward Merwitz, a 62-year-old shipfitter exposed from 1965-1970, received $7.25 million in 2014 after developing mesothelioma. Eight companies settled confidentially before trial, with Rockbestos Cable Corporation paying $805,250 of the award. Three Navy veterans received $14 million collectively in consolidated cases, with one receiving $6 million and two others $4 million each for mesothelioma caused by exposure to pumps, valves, and gaskets.
Additional verdicts demonstrate consistent success for shipyard workers: $40 million for a Navy boiler tender; $7.2 million for an aircraft carrier worker's family; $6.5 million for a submariner; $5.8 million for a worker with pleural mesothelioma.[23]
What Trust Fund Compensation Is Available?
Over $30 billion remains available in bankruptcy trust funds from manufacturers including IMO Industries, Johns Manville, Owens Corning, and GAF Corporation.[24] These trusts compensate victims when original manufacturers declared bankruptcy to escape mounting liabilities. According to Danziger & De Llano case data, Philadelphia Naval Shipyard workers typically qualify for claims against multiple trusts based on the documented use of products from dozens of manufacturers at the facility.
| ✓ Multiple Compensation Sources Available: Philadelphia Naval Shipyard workers and their families can pursue multiple compensation sources simultaneously. Trust fund claims don't reduce your insurance benefits, VA disability payments, or legal settlement amounts. An experienced attorney can identify all available sources to maximize your total recovery. |
What VA Benefits Can Veterans Receive?
VA disability benefits provide crucial ongoing support for Navy veterans exposed at Philadelphia Naval Shipyard.[25] Veterans with mesothelioma receive 100% disability ratings worth $3,831.30 monthly for single veterans or $4,044.91 for married veterans, totaling up to $48,539 annually. Additional benefits include free VA medical care, Aid and Attendance payments for those requiring assistance with daily activities, and survivor benefits for spouses and dependents.
The VA requires only proof of honorable discharge and service-connected exposure, with no filing deadline for mesothelioma claims. Success rates remain high for mesothelioma cases, with average processing taking 3-6 months. Veterans typically receive over $1 million from legal claims plus $48,000+ annually from VA benefits when pursuing all available compensation simultaneously.[26]
Pennsylvania workers' compensation covers civilian employees, while the Federal Employees Compensation Act protects federal workers. Maritime workers access benefits through the Jones Act and Longshore and Harbor Workers' Compensation Act.
| "We work closely with veterans and civilian workers to identify every potential compensation source. Many families don't realize they can pursue trust funds, VA benefits, and lawsuits simultaneously. The key is acting quickly because statutes of limitations vary by state, and evidence becomes harder to gather over time." |
| — Michelle Whitman, Attorney, Danziger & De Llano |
What Is the Current Status of Philadelphia Naval Shipyard?
The Base Realignment and Closure Commission recommended closure in 1991, citing foreign competition and reduced post-Cold War requirements. Despite legal challenges including Senator Arlen Specter's personal Supreme Court argument, the shipyard officially closed September 26, 1996, after 195 years of continuous operation. The USS Blue Ridge, launched November 14, 1970, became the last vessel built at Philadelphia, and ironically remains active today as the oldest deployable warship in the U.S. Navy.[27]
Philadelphia's remarkable transformation began in March 2000 when the city acquired 1,000 acres for redevelopment. The Philadelphia Industrial Development Corporation invested $150 million in infrastructure, leveraging over $750 million in private investment. Today's Navy Yard houses 150+ companies employing 16,500 workers across 8 million square feet, with major tenants including Urban Outfitters, GlaxoSmithKline, and Hanwha Philadelphia Shipyard.
Environmental remediation began in 1991 when the Navy initiated assessment of contamination spanning nearly two centuries. The EPA and Pennsylvania Department of Environmental Protection supervised cleanup of asbestos in buildings, PCB-contaminated transformers, underground storage tanks, heavy metals, and volatile organic compounds. Remediation included asbestos abatement, soil removal, landfill capping for asbestos waste, and installation of long-term groundwater monitoring systems.
What About the Mothball Fleet?
Philadelphia's Naval Inactive Ship Maintenance Facility currently stores approximately 20+ vessels, making it one of America's largest ship storage sites. The facility houses five Ticonderoga-class cruisers including the lead ship USS Ticonderoga (CG-47), plus 15 Oliver Hazard Perry-class frigates, more than any other storage facility. These vessels undergo preservation through humidity control systems, cathodic protection against corrosion, and continuous flood and fire watch maintenance.
The recent departure of USS John F. Kennedy on January 16, 2025, for scrapping in Brownsville, Texas, marked the end of an era. This last conventionally-powered carrier to receive major Philadelphia work symbolized the yard's transition from active shipbuilding to vessel storage and disposal. Environmental concerns persist regarding lead paint, asbestos, and potential fuel contamination from aging ships, requiring ongoing monitoring and remediation efforts.
How Can Affected Workers and Families Get Help?
For Philadelphia Naval Shipyard workers diagnosed with mesothelioma, asbestosis, or other asbestos-related diseases, immediate action is essential to protect your legal rights and access available compensation.[28] Pennsylvania's statute of limitations for personal injury claims is two years from diagnosis or discovery of the connection between your illness and asbestos exposure. However, trust fund claims and VA benefits may have different deadlines, making prompt consultation with an experienced attorney critical.
| ⏰ Time-Sensitive: Filing deadlines vary and evidence preservation is critical. Employment records, co-worker testimony, and company documents become harder to obtain over time. If you or a family member worked at Philadelphia Naval Shipyard between 1940-1990, contact an attorney immediately for a free case evaluation, even if you have not yet been diagnosed with an asbestos-related disease. |
What Documents Should Workers Gather?
Workers should begin gathering documentation immediately upon diagnosis or suspicion of asbestos-related illness:
- Employment records including dates, job titles, and departments
- Military service records (DD-214 for veterans)
- Medical records and diagnostic imaging
- Names and contact information for former co-workers
- Photos or documentation of workplace conditions
- Social Security earnings records showing employment history
- Union membership records if applicable
An experienced mesothelioma law firm can help obtain additional documentation including asbestos product identification records, company bankruptcy and trust fund information, expert witness reports, and historical exposure documentation that strengthens your claim.
