USS Sea Cat (SS/AGSS-399), a Balao-class submarine, was a ship of the United States Navy named for a shortened form of sea catfish, a marine fish of little food value found off the southeastern coast of the United States commissioned on 16 May 1944, with Commander Rob Roy McGregor in command. During World War II Sea Cat operated within the Pacific theatre, conducting four war patrols in wolf packs accounting for up to 17400 tons in the form of three cargo ships and an enemy vessel (17000 tons unconfirmed by wartime Japanese records). Sea Cat earned three battle stars for her World War II service.
