With 5 battle stars earned for World War II service, the submarine was laid down in 1942 by the Electric Boat Company in Connecticut. It completed 7 war patrols, out of which 5 were successful. Since it was built during the middle of the last century, when asbestos enjoyed great popularity as a construction material, the USS Mingo had this carcinogen present on it, mostly in the wall insulation. Therefore, we strongly advise veterans who served on it to keep a close eye on their health by undergoing yearly medical examinations to ensure the asbestos fibers they breathed in have not damaged their lungs. In 1955, the vessel was transferred to Japan, returned to the U.S. control in 1966 and eventually sold for scrap 7 years later.
