Laid down by Union Iron Works, the submarine was launched in 1918 and commissioned 2 years later. However, in 1922, it was temporarily decommissioned for alteration, during which asbestos insulation might have also been installed on the walls of the vessel. For this reason, we highly encourage people who served on it to undergo periodical medical examinations in order to make sure the asbestos they breathed in caused no harm to their lungs. The USS S-33 won one battle star during World War II. It was permanently decommissioned in 1945 and later sold for scrap.
