USS Wahoo (SS-238) was a Gato-class submarine, the first United States Navy ship to be named for the wahoo. Construction started before the U.S. entered World War II, and she was commissioned after entry. Wahoo was assigned to the Pacific theatre. She gained fame as an aggressive and highly successful submarine after Lieutenant Commander Dudley Walker "Mush" Morton became her skipper. She was sunk by Japanese aircraft in October 1943 while returning home from a patrol in the Sea of Japan.
