The USS S-37 (SS-142) was launched in 1919 and was also part of the United States Asiatic Fleet. What is remarkable regarding this submarine is its Natsushio victory and the fact that it won 5 battle stars during World War II. Nonetheless, asbestos exposure might have taken place on it, as the mineral was widely used as wall insulation during that time. The submarine was struck from the Naval Vessel Register in 1945 and sank en route for being used as a bombing target. Particularly before 1980, it is likely that Navy veterans were in contact with dangerous levels of asbestos, increasing their chances of developing diseases like lung cancer, asbestosis, and mesothelioma. Asbestos was routinely utilized to insulate steam pipes in ships built and repaired at shipyards across the United States. There was even an asbestos mixing room where workers would combine magnesium oxide and asbestos fibers to make the insulation. Additionally, protective clothing worn by welders and foundrymen included asbestos fiber in the leggings, aprons, and gloves.
