This submarine was laid down by Union Iron Works in San Francisco and launched in 1918, which means asbestos might have been present in its walls as insulation. It conducted tests and exercises off the California coast in the summer of 1921. The USS S-30 was decommissioned twice for engine alterations and other reparations. It also won 2 battle stars during World War II. The vessel was finally decommissioned in 1945 and later sold for scrap.
