A History of Navy Asbestos Exposure Posted on March 18, 2026March 18, 2026 by Christopher Dryfoos 4 Min Read For most of the 20th century, the Navy used tons of asbestos to fireproof and insulate ships. In fact, virtually all U.S. Navy ships used asbestos, and anyone exposed could develop dangerous cancers like mesothelioma later in life. This history of Navy asbestos exposure spans decades, beginning in 1922 and running through the 1980s, with usage peaking during World War II. As a result, millions of U.S. Navy veterans were put in danger of exposure and serious cancers like mesothelioma. “Navy vessels were using asbestos for so many components, like insulation, soundproofing, fireproofing, throughout most of the vessels that were produced into the 1980s.” – Major Jonathan Nelson (Ret), VA-accredited attorney & Marine Corps veteran The Mesothelioma Veterans Center stands ready to support veterans now facing mesothelioma from Navy asbestos exposure.

The first patent for asbestos steam insulation was issued in 1828, and through the rest of the 1800s, key asbestos-containing products like lagging, gaskets, and packings, were developed — all of which would become staples of U.S. Navy ship production in the 20th century. Early 20th Century U.S. Navy Asbestos Use (1922-1939) For much of the 20th century, every branch of the U.S. military heavily used asbestos to insulate and fireproof barracks and all kinds of transportation — but none as much as the Navy. Following World War I, the U.S. began officially mandating the use of asbestos aboard its vessels, starting with the construction of new submarines in 1922, according to The Ulster Medical Journal. Did you know?The U.S. would expand use of asbestos through the 1930s, and by 1939, the Navy began to stockpile asbestos-containing materials to construct and service its expanding ship fleet. At the time, the risks of asbestos weren’t understood by the public. Instead, it was seen as an inexpensive and safe way to keep high-heat components like boilers well-insulated and functioning properly. World War II Navy Asbestos Use (1941-1945) As World War II drove the U.S. Navy to deploy thousands of battleships, aircraft carriers, and other vessels, asbestos use on Navy ships skyrocketed. In fact, government mandates required the use of asbestos aboard all U.S. Navy ships, and an order from President Franklin Delano Roosevelt gave the military priority access to asbestos components through 1945. Heavy asbestos exposure was common among Navy workers such as: Boiler technicians Insulators Longshoremen Machinist mates Pipefitters Shipyard workers Nearly 4.3 million Americans worked in shipyards during World War II, and the yards were so clouded with asbestos dust that workers couldn’t see to the other end, per The New York Times. Of these employees, nearly 14 in every 1,000 died of asbestos-related cancer, as noted by The Virginian-Pilot. If you or a loved one served in the U.S. Navy, you could have been exposed too.

Navy Asbestos Risks in the Korean and Vietnam Wars (1950-1975) U.S. Navy veterans continued to suffer exposure to asbestos through Korea and Vietnam, as mandates requiring the use of asbestos aboard military vessels remained in place. Anyone serving could have been exposed, but those at the highest risk worked with asbestos every day. For instance, Walter Twidwell worked directly with asbestos boilers through his 20-year Navy career, where he served in both Korea and Vietnam. Decades later, he developed mesothelioma. “I was a boiler tender when I went aboard my first ship. I asked them what the material was made out of on the boilers and they told me asbestos. It didn’t kill anybody on the spot. It took years later to start catching up with us.” – Walter Twidwell, mesothelioma patient & U.S. Navy veteran In 1973, the U.S. Navy started to phase out the use of some asbestos-containing materials aboard its ships. But, every vessel built before 1975 was believed to contain asbestos components like insulation, per the Occupational Safety and Health Administration (OSHA). This amounts to over 3,300 U.S. Navy ships. When Did the Navy Stop Using Asbestos? (1980s-Present) In the late 1970s, the dangers of asbestos became publicly known, leading to major changes in the U.S. Navy’s use of asbestos. By the late 1970s, the U.S. Navy was taking steps to limit the use of asbestos aboard its ships, and finally stopped using it altogether by the early 1980s. It also began conducting major renovations throughout the 1980s to keep U.S. Navy veterans safe while serving. Only a very small handful of ships that were built when asbestos was in use are still active today. However, many U.S. Navy veterans are still in danger of getting sick today because mesothelioma takes 10-50 years to form after asbestos exposure.
