Built in 1942 by Portsmouth Navy Yard, the submarine earned 7 battle stars for World War II performance. It was commissioned one year later and struck from the Naval Vessel Register in 1968, subsequently being sold for scrapping. Since it was laid down during the heyday of asbestos use, the USS Billfish contained this toxic mineral in numerous places onboard, such as the wall insulation, the gaskets, the boilers and the valves. Exposure to asbestos fibers occurs when one breathes them in, which may lead to serious diseases such as mesothelioma within 20 to 50 years later. We strongly encourage all veterans who served on this submarine to prevent the development of such a disease by undergoing annual medical examinations consisting of chest X-rays and, possibly, CT-scans. This way, they will rest assured their lungs have not been affected by asbestos exposure.
