Lost on 26 AUG 1949 after being hammered by a violent polar gale off Norway, causing an electrical fire and battery explosion that generated hydrogen and chlorine gasses.
In extremely bad weather, men of USS COCHINO and USS TUSK (SS-426) fought to save the submarine for fourteen hours, performing acts of skillful seamanship and high courage. After a second battery explosion, abandon ship was ordered and USS COCHINO sank at 71°35' N., 23°35' E.
USS TUSK's crew rescued all of USS COCHINO's men except for one civilian engineer. Six sailors from USS TUSK were lost during the rescue.
