Many veterans, shipbuilders and others experienced asbestos exposure on ships. Ship construction incorporated products like asbestos insulation for much of the 20th century. Naval and commercial vessels both used these products. People who worked or served on them may develop mesothelioma.

01. Asbestos Use on Ships

How Was Asbestos Used on Ships?

Commercial ships and naval vessels both need to withstand fire and extreme heat. As a result, asbestos was incorporated into ship and shipbuilding products to make them durable and fire resistant. The mineral was especially common in insulation used in boiler rooms, but ships also contained many other asbestos products like cement and adhesives.

Common Asbestos Products Used in Ship Construction

Although many products on ships contained asbestos, the mineral was most heavily used in the boiler and engine rooms and for insulation purposes.

For instance, boilers produce high temperatures and steam. To contain the heat, asbestos insulation was often used to line the interior of the equipment. Most boiler insulation on ships contained about 15% asbestos. Other asbestos components, such as gaskets, were often used in boilers to further improve fireproofing and durability.

Pipes on ships may also contain large amounts of asbestos insulation. Research suggests pipes were often insulated with a layer of felt containing up to 50% asbestos fibers.

Any repairs or maintenance on asbestos materials could cause dangerous fibers to become airborne. Because ships had tight quarters and poor ventilation, this could put anyone on board at risk of asbestos exposure.

Asbestos Use on Ships Today

Today, asbestos on ships is less of a hazard than it once was. Although asbestos is still not fully banned, commercial and military ships stopped using it beginning in the late 1970s. But older ships may still contain asbestos products.

If the asbestos materials remain in good condition and are not disturbed, they are not an immediate danger to human health. However, any disturbed asbestos materials may pose an exposure risk for anyone on the ships.

02. Notable Ship Types

Navy Ships Built With Asbestos

Many types of ships used asbestos, ranging from aircraft carriers to submarines. As a result, hundreds of ships used commercially and by the military contained the mineral. For most of the 20th century, Navy ships contained many products made by asbestos companies. This put thousands of crew members, shipyard workers, veterans and passengers at risk of exposure.

Aircraft Carriers

Aircraft carriers are warships used to transport aircraft. Aircraft carriers were first built in 1922 and became more prominent during times of war. These Navy vessels were in World War II, the Vietnam War, the Korean War and the Cold War. During these wars, asbestos was a popular component in shipbuilding, putting those who served on or maintained aircraft carriers at risk of exposure.

Amphibious Warships

Amphibious warships are designed to land ground force cargo and support U.S. Marines on land. The Navy largely commissioned these ships during the 1940s, when asbestos use was prominent. Amphibious warships, such as the USS Cavalier, were built with many asbestos products. This posed a health risk to crew members and veterans.

Auxiliary Vessels

Auxiliary vessels play an important role in the U.S. Navy. These ships support combat vessels on missions by supplying fuel, ammunition, supplies and more. They have been a critical part of the Navy for more than 100 years. Auxiliary ships used asbestos just like many other Navy ships. Asbestos was used during ship construction and in various components, which put sailors at risk of exposure.


Navy battleships were versatile during wartime. Construction of the popular ships started in the early 1900s. As a result, many battleships were built with asbestos-containing products to protect them from extreme heat and fire. Battleships could carry several thousand passengers at a time, putting crew members, soldiers and others at risk of asbestos exposure.


Cruisers are large combat ships that served during World War I, World War II, the Korean War, the Vietnam War and the Cold War. More than 140 Navy cruisers were constructed and repaired with asbestos-containing products. Navy personnel aboard cruisers were at great risk of asbestos exposure, especially those serving in the engine and boiler rooms.


Navy destroyers are fast warships first commissioned in the early 1900s. Destroyers were built and repaired using asbestos in boilers, pumps and other equipment. With more than 300 active destroyers during World War II alone, thousands of veterans potentially faced exposure aboard these ships.

Destroyer Escorts

Destroyer escorts were primarily used to support the Merchant Marines during World War II. The United States built more than 450 destroyer escorts to support these efforts. Many of these ships contained asbestos products. As a result, thousands of people faced exposure and the risk of developing mesothelioma.

Escort Carriers

Escort carriers were predominantly used during World War II. More than 120 escort carriers were built during this time, all of which may have used asbestos materials. Sailors who served on or maintained these ships risked asbestos exposure.


Frigates were another active ship type during World War II. Frigates primarily escorted and protected destroyers. At least 114 frigates were active during World War II. All of these ships may have been built and repaired with asbestos products.

Merchant Marine Ships

The Merchant Marines serve as an auxiliary branch of the military. At one point, there were more than 1,000 Merchant Marine ships in its fleet. Asbestos was frequently used in the ships’ construction. Although many of these ships are no longer active, Merchant Mariners are still at risk of mesothelioma cancer from past exposure.


Minesweepers were responsible for clearing an open area of mines so larger naval warships could pass through safely. During World War II alone, shipbuilders constructed more than 350 minesweepers. Those who served aboard these ships may have been exposed to asbestos.


Submarines served in many wartime efforts. During World War II, there were at least 280 submarines in active service. Those who worked or served on submarines spent much of their time in confined areas with poor ventilation. As a result, they may have been frequently exposed to high levels of harmful asbestos, leaving many at risk of developing mesothelioma.

03. Who Is at Risk?

Who Is at Risk of Asbestos Exposure on Ships?

Crew members, Navy personnel, shipyard workers and passengers were at risk of asbestos exposure on ships. Some people who worked in poorly ventilated spaces, like boiler workers, faced especially high risks of exposure. Navy veterans and shipyard workers are among the most at risk for exposure and developing a disease such as mesothelioma.

Family members of these workers and military service members were also at risk of secondary exposure. Workers could unknowingly bring home asbestos fibers on their person.

Occupations at Risk of Asbestos Exposure on Ships

No amount of asbestos exposure is considered safe. Veterans and others who worked on ships containing asbestos materials may be at risk of diseases such as mesothelioma, asbestosis and asbestos lung cancer. It can take decades after exposure for these illnesses to present symptoms.

Individuals who believe they may have been exposed to asbestos on a ship should talk to their doctors.

04. Asbestos Lawsuits

Asbestos Lawsuits and Compensation

Veterans and others who develop mesothelioma from asbestos exposure on ships have compensation options. Many veterans have sought payouts from companies that provided asbestos materials to the U.S. Navy. As a result of successful lawsuits, these companies have been found liable for millions of dollars.

Mesothelioma law firms specialize in representing asbestos exposure victims. Lawyers at these firms have won numerous settlements and verdicts for their clients.

Navy Veteran With Mesothelioma Awarded $40 Million

In 2018, a New York jury awarded a Navy veteran $40 million in a lawsuit against Goodyear. The veteran served as a boiler tender in the Navy starting in 1954. He conducted maintenance and repair work on seven vessels. During his service, he faced asbestos exposure from gaskets produced by Goodyear. He was diagnosed with mesothelioma in 2017.

Navy or Marine Corps veterans who served on asbestos-containing naval ships may be eligible for various veterans benefits. Through the U.S. Department of Veterans Affairs (VA), veterans who develop an asbestos-related disease may be eligible for low-cost treatment at VA health centers. Veterans may also be eligible for VA benefits.

Some individuals may also be eligible to file asbestos trust fund claims. Various asbestos manufacturers have gone through bankruptcy proceedings and created trust funds to compensate victims.

An experienced lawyer can help asbestos victims understand all of their filing options.

05. Reducing Exposure Risks

Reducing Asbestos Exposure Risks on Ships

Although asbestos use was no longer common after the 1980s, past uses may still pose a health risk. The Occupational Safety and Health Administration (OSHA) developed a program and regulations to help prevent exposure on ships. The U.S. Navy also created a program to help those with previous exposure.

OSHA maintains the National Emphasis Program on Shipbreaking to reduce workplace hazards at shipyards. As part of the program, ships and shipyards must undergo safety and health inspections. These inspections may identify hazards, such as asbestos, and help eliminate exposure risks. In addition to this program, the agency has other regulations in place for asbestos handling at shipyards to protect workers.

The Navy also developed a program to help monitor veterans’ health, called the Asbestos Medical Surveillance Program (AMSP). The AMSP maintains records for those who have faced occupational exposure. Doctors monitor their health through various exams such as lung tests.

These programs and other federal asbestos regulations can help those who already experienced exposure and potentially prevent future asbestos exposure on ships.
