Among all branches of the U.S. military, Navy veterans face the highest risk of developing mesothelioma, accounting for nearly one-third of all veteran mesothelioma cases. This disproportionate impact isn’t coincidental, it’s the direct result of extensive asbestos use throughout the Navy’s fleet and shipbuilding facilities from the 1930s through the 1980s. From aircraft carriers to submarines, destroyers to supply ships, virtually every vessel in the U.S. Navy was constructed with hundreds of asbestos-containing products. Understanding why Navy veterans were so heavily exposed, which ships and shipyards posed the greatest risks, and what this means for veterans today is critical for early detection and accessing entitled benefits.
High-Risk Navy Ships: Which Vessels Had the Most Asbestos
While nearly all Navy vessels built before 1980 contained asbestos, certain ship classes and specific vessels exposed their crews to particularly high levels. Resources focused on veterans who served in the Navy document hundreds of ships where sailors developed mesothelioma decades later.
Aircraft Carriers
Aircraft carriers, the Navy’s largest vessels, contained massive amounts of asbestos throughout their enormous structures. Famous carriers like USS Enterprise, USS Midway, USS Kitty Hawk, USS Constellation, USS America, and USS Saratoga all exposed their crews to asbestos. With crew complements often exceeding 5,000 sailors, these ships put thousands at risk during each deployment.
Destroyers and Cruisers
Smaller warships like destroyers and cruisers packed extensive mechanical systems into tight spaces, requiring heavy asbestos insulation. Notable vessels include USS Fletcher-class destroyers, USS Gearing-class destroyers, and numerous guided-missile cruisers from the 1960s and 1970s.
Submarines
Submarines presented unique dangers due to their extremely confined spaces and sealed environments. Asbestos fibers released in a submarine had virtually no way to escape, and crew members breathed recycled air containing these particles. Fleet submarines, ballistic missile submarines, and attack submarines all contained extensive asbestos insulation around their nuclear reactors, steam systems, and throughout their pressure hulls.
Amphibious Assault Ships and Support Vessels
Landing ships, supply vessels, oilers, tenders, and other support craft also exposed their crews to asbestos. Ships like USS Iwo Jima-class amphibious assault ships, USS Sacramento-class fast combat support ships, and countless others put sailors at risk.
Shipyards: Where the Exposure Began
Navy shipyards represented another major source of asbestos exposure for both active-duty sailors and civilian workers. During construction, overhaul, and repair operations, shipyard workers and ship’s crew members worked side-by-side in spaces filled with asbestos dust. According to detailed resources about veterans and asbestos-related diseases, major shipyards across the United States exposed hundreds of thousands of workers to deadly asbestos fibers.
Major Naval Shipyards with Known Asbestos Exposure
Pearl Harbor Naval Shipyard, Hawaii: This facility serviced the entire Pacific Fleet, with continuous ship construction and repair operations exposing workers from the 1940s through the 1980s.
Norfolk Naval Shipyard, Virginia: As one of the oldest and largest shipyards, Norfolk built and maintained hundreds of vessels, exposing countless sailors and civilian workers to asbestos.
Puget Sound Naval Shipyard, Washington: Located in Bremerton, this shipyard specialized in submarine construction and nuclear-powered vessel maintenance, areas requiring extensive asbestos use.
Philadelphia Naval Shipyard, Pennsylvania: Active from 1801 until closure in 1995, this facility exposed generations of workers to asbestos during ship construction and decommissioning.
Long Beach Naval Shipyard, California: Though closed in 1997, this facility’s legacy of asbestos exposure continues to affect veterans today.
Portsmouth Naval Shipyard, Maine: Specializing in submarine maintenance and overhaul, this facility exposed submarine crews and shipyard workers to high asbestos concentrations.
Other significant yards included Charleston Naval Shipyard in South Carolina, Mare Island Naval Shipyard in California, and Hunters Point Naval Shipyard in San Francisco.
The Navy’s Relationship with Asbestos: A Deadly Dependence
The U.S. Navy became the single largest consumer of asbestos-containing materials in the entire military. This wasn’t due to carelessness or ignorance initially, asbestos possessed properties that seemed ideal for naval vessels. The mineral was fireproof, heat-resistant, durable, inexpensive, and provided excellent insulation against both heat and sound. In the confined, high-temperature environment of a military ship, these characteristics appeared perfect for protecting sailors and equipment.
Between World War II and the late 1970s, the Navy incorporated asbestos into virtually every component of ship construction. Engine rooms, boiler rooms, pipe insulation, gaskets, valves, pumps, electrical wiring, deck materials, hull insulation, mess halls, sleeping quarters, and even the ships’ drinking water systems contained asbestos. According to comprehensive information for veterans exposed to asbestos, some estimates suggest that a single Navy vessel could contain more than 300 different asbestos-containing products.
The tragic reality is that asbestos manufacturers knew about the health dangers as early as the 1930s but deliberately concealed this information from the military and the public. Internal company documents later revealed in lawsuits showed that these corporations prioritized profits over the safety of American service members. The Navy, trusting these suppliers, unknowingly placed millions of sailors in harm’s way.
High-Risk Areas Aboard Naval Vessels
Not all areas of a ship posed equal risk. Certain spaces exposed sailors to concentrated levels of airborne asbestos fibers, particularly when materials were damaged, disturbed during maintenance, or degraded from age and use.
Engine Rooms and Boiler Rooms
Engine rooms and boiler rooms represented the most dangerous areas aboard any Navy vessel. These spaces operated at extreme temperatures, requiring extensive insulation on every pipe, valve, turbine, and surface. Sailors working in these compartments, including machinist’s mates, boiler technicians, and enginemen, faced daily exposure to asbestos dust. When insulation cracked from heat stress or required repair, clouds of asbestos fibers filled these poorly ventilated spaces.
The confined nature of below-deck compartments meant asbestos particles had nowhere to dissipate. Ventilation systems, rather than removing contamination, often circulated asbestos fibers throughout the ship, exposing crew members in other areas as well.
Pump Rooms and Pipe Spaces
Naval vessels contained miles of piping for steam, water, fuel, and hydraulic systems, nearly all wrapped in asbestos insulation. Pump rooms, where these systems intersected, became hotspots for exposure. Pipefitters, hull technicians, and damage controlmen routinely worked in these spaces, cutting, fitting, and repairing asbestos-insulated pipes. Each cut or repair released countless microscopic fibers into the air.
Sleeping Quarters and Mess Halls
Even areas where sailors slept and ate weren’t safe. Overhead insulation, deck tiles, wall panels, and ventilation systems in berthing areas and mess halls contained asbestos. While these spaces might not have generated the same fiber concentrations as engine rooms, the cumulative exposure from spending hours daily in these compartments added to each sailor’s total asbestos burden.
Shipboard Repair and Maintenance
Perhaps the most dangerous exposures occurred during repair and maintenance operations. Grinding, cutting, removing old insulation, and installing new equipment disturbed asbestos materials, creating hazardous conditions. Many veterans recall clouds of white dust filling compartments during these tasks, with no protective equipment provided because the dangers weren’t understood, or weren’t disclosed.
Why Navy Veterans Still Face Risks Today
Even though the Navy stopped using asbestos in new construction by the early 1980s, exposure risks persist. Older vessels still in service, particularly those undergoing maintenance or decommissioning, can expose current service members to asbestos. Additionally, the long latency period of mesothelioma means veterans who served decades ago are only now developing symptoms.
Understanding legal benefits and compensation available to Navy veterans with mesothelioma has become increasingly important as more veterans receive diagnoses. The VA recognizes service-connected asbestos exposure and provides disability compensation, but veterans can also pursue additional compensation through asbestos trust funds and lawsuits against the manufacturers who supplied these deadly products to the Navy.
Occupational Specialties at Highest Risk
Certain Navy ratings (job specialties) faced dramatically higher exposure levels than others:
Machinist’s Mates (MM): Working directly with engines, pumps, and machinery wrapped in asbestos insulation.
Boiler Technicians (BT): Operating and maintaining boilers with extensive asbestos components.
Hull Maintenance Technicians (HT): Repairing and maintaining ship structures, pipes, and ventilation systems.
Damage Controlmen (DC): Managing firefighting equipment and damage control systems containing asbestos.
Pipefitters: Installing and repairing asbestos-insulated piping systems.
Electrician’s Mates (EM): Working with asbestos-insulated electrical systems and wiring.
Enginemen (EN): Operating and maintaining engines with asbestos components.
However, detailed information available through veteran-focused mesothelioma resources emphasizes that sailors in virtually any rating could have been exposed, particularly during general quarters, damage control drills, or when simply living aboard vessels for months or years at a time.
What Navy Veterans Should Know
If you served in the Navy between 1930 and 1980, you were likely exposed to asbestos regardless of your rating or assigned ship. Understanding your exposure history is crucial for several reasons:
First, awareness allows you to monitor for early warning signs of mesothelioma and seek medical screening. Early detection significantly improves treatment outcomes.
Second, documenting your service aboard specific ships or at particular shipyards strengthens your VA disability claim. The VA requires proof of service-connected exposure, and knowing which vessels you served on helps establish this connection.
Third, understanding which ships and shipyards used asbestos supports potential legal claims against manufacturers. Specialized attorneys maintain extensive databases documenting asbestos products used on specific ships, helping veterans prove exposure even if their memories of specific incidents have faded.
The disproportionate impact of mesothelioma on Navy veterans represents one of the most significant occupational health disasters in American military history. While nothing can undo the exposure that occurred, understanding the scope of the problem, knowing your risks, and accessing available benefits and compensation can help you and your family face a mesothelioma diagnosis with greater resources and support.
