Commissioned in 1942, the submarine received 8 battle stars for World War II activity. With Lieutenant Commander William T. Nelson in command, it completed 10 war patrols. On 5 May, she made a night attack conducted by sound and radar alone, firing three torpedoes at a target for one possible hit. After patrolling off Cape Oxford, the USS Peto (SS-265) headed for Brisbane on 20 May.
In 1960, the submarine was struck from the Naval Vessel Register and was subsequently sold for scrapping. Since asbestos was a very popular building material when the vessel was laid down, the toxic mineral lurked on the wall insulation, as well as in other machinery and equipment present on it. For this reason, we highly recommend veterans who served on this submarine to keep a close eye on their health and undergo yearly medical examinations to make sure the asbestos fibers they inhaled have not caused any damage to their lungs.
