The keel of the USS Nautilus (SS-168) was laid down by Mare Island Naval Shipyard in California in 1927. The vessel received multiple awards, such as the Presidential Unit Citation and the Asiatic–Pacific Campaign Medal, also winning 14 battle stars. Additionally, Lieutenant Commander William H. Brockman Jr. was presented with a Navy Cross for his actions during the Battle of Midway. The submarine was decommissioned in 1945 and later sold for scrap.
Aboard US Navy vessels built in the first half of the 20th century, there are asbestos-containing boilers, pumps, valves, and miles of pipes. All of this equipment requires maintenance or repair work over the life of the ship. If you served in the Navy prior to 1980, you may still be at risk of developing asbestos-related illnesses such as mesothelioma, and you should make an appointment with your doctor at your earliest convenience.
