The USS S-20 (SS-125) was a first-group S-class submarine of the United States Navy, laid down on 15 August 1918 by the Bethlehem Shipbuilding Corporation's Fore River Shipyard, Quincy, Massachusetts, launched on 9 June 1920 sponsored by Miss Anne Claggett Zell and commissioned on 22 November 1922 with Lieutenant John A. Brownell in command. Because it underwent reconstruction during the heyday of asbestos, the mineral might have been present on this submarine, too. The USS S-20 was decommissioned in 1945 and subsequently sold to North American Smelting Company for scrapping. In the early 20th century, the US Navy used asbestos as a source of insulation in naval structures. Those serving aboard ships, especially in close proximity to engine rooms, engine rooms, navigation rooms, weapons, and ammunition storage rooms, were at the highest risk of exposure. If you suffer from a disease caused by exposure to asbestos and you are also a Navy veteran, you may be eligible for compensation from asbestos trust funds and VA claims.
