The Navy’s Asbestos Legacy: Understanding Why Veterans Face Higher Mesothelioma Risks

For decades, the United States Navy employed asbestos as a “miracle material” to fireproof ships, insulate engines, and protect sailors from the extreme heat of naval operations. But this came at a horrific cost: generations of veterans are now at increased risk of mesothelioma, a rare and lethal cancer that is caused by asbestos exposure. The following are three reasons why Navy veterans are still particularly vulnerable to mesothelioma and why awareness can be a lifesaver.

1. Asbestos Was Embedded in the Naval Infrastructure

Thanks to its heat-resistance properties, asbestos was used in shipbuilding from the 1930s to the early 1980s. It was generally installed to protect boilers, pipes, and electrical equipment on submarines, aircraft carriers, and other Navy vessels. Working in narrow and poorly ventilated areas in ships, such as engine rooms and hull compartments, put Navy personnel at risk from asbestos dust from insulation, gaskets, and adhesives. Even workers who did not work with asbestos directly, such as electricians, welders, or mechanics, were secondarily exposed as fibers hitched rides on clothing, tools, and living areas.

For example, a sailor working on repairing a steam valve might have inhaled asbestos fibers released from nearby pipe insulation. These fibers gradually accumulated in the lungs and, over the years, could result in breathing problems and, decades later, mesothelioma. Since asbestos was in so many parts of naval facilities at the time, the risks affected almost every sailor from that era.

2. Latency Periods Delay Diagnosis and Awareness

Mesothelioma has such a long incubation period and may take up to 50 years to develop after asbestos exposure. Many mesothelioma Navy veterans were exposed in their youth. Yet it may not be until their 60s or 70s that they notice symptoms of shortness of breath, chest pain, or fatigue.

By then, they may no longer associate their illness with their military duty. Because of this delay, catching cancer early is not always possible, although it is the best time for successful treatment. The problem is also exacerbated by the fact that mesothelioma symptoms closely resemble those of common age-related diseases. These include COPD or heart disease.

Due to this, misdiagnosis is common. A veteran can dismiss a chronic cough as a part of normal aging or the result of smoking and have no idea it could be a sign of much more. When mesothelioma is diagnosed, the disease is in its later stages. Veterans need to be aware of this delayed correlation so that they can go for screenings more and let doctors know about their military service during medical exams.

3. Continued Exposure Risks in Deactivated Ships

Even after the Navy reduced its use of asbestos, many veterans continued to be exposed to it during vessel repair and decommissioning. Older ships, some of which remain in operation today, contain aging asbestos materials that become increasingly dangerous with age. As these materials degrade, they release toxic fibres during maintenance or demolition. Shipyard workers or salvage experts handling such ships never wore proper gear or received guidance on handling asbestos safely without endangering themselves.

For example, a veteran deployed to upgrade a Cold War-era destroyer might have inhaled asbestos dust while removing old insulation, thus inadvertently restarting the risk of mesothelioma cancer. Interest groups now advocate for increased safety protocols and comprehensive asbestos removal in aging Naval facilities, yet thousands of veterans still carry the burden of their earlier exposures.

Endnote

The Navy’s asbestos legacy is a stark reminder of veterans’ sacrifices and the necessity for continued support. Veterans with a history of past naval service should inform their healthcare providers about potential asbestos exposure, even if it has been several years since exposure. Early testing, including imaging scans and pulmonary function tests, can detect mesothelioma at more treatable stages. Also, facilities like the VA offer asbestos-related disease specialty care and benefits
