USS S-21 (SS-126) Areas With Asbestos Exposure

Renowned for partaking in the first gravity measurements at sea, the USS S-21 was built at Bethlehem Shipbuilding Corporation in 1918. The submarine was also used in the first gravimetric observations at sea conducted by the United States. While it is not a certainty, asbestos might have been present in the wall insulation of the vessel, which means a considerable health danger to those who were present on it. The submarine was decommissioned in 1942, then transferred to the Royal Navy to finally be sunk as a target in 1945.
