The keel of the USS Redfin was laid down by the Manitowoc Shipbuilding Company in 1942, as was the case of most Gato-class submarines. It was later turned into a radar picket submarine. During World War II, the USS Redfin earned numerous awards, including the Navy Occupation Medal, the Asiatic-Pacific Campaign Medal and the National Defense Service Medal, as well as 6 battle stars and one service star. However, despite the remarkable performance of this submarine, it contained asbestos in the wall insulation and in other components such as gaskets and valves, too. For this reason, we advise people who served on it to keep a close eye on their health and undergo periodical medical examinations to ensure the asbestos fibers they breathed in have not damaged their lungs. The submarine was struck from the Naval Vessel Register in 1970 and subsequently sold for scrap.
