USS Barb (SS-220), a Gato-class submarine, was the first ship of the United States Navy to be named for the barbus. The craft compiled one of the most outstanding submarine records of World War II. During the seven war patrols she conducted in the Pacific between March 1944-August 1945, Barb is officially credited with sinking 17 enemy vessels totaling 96,628 tons, including the Japanese aircraft carrier Unyo. In recognition of one outstanding patrol, Commander Eugene Fluckey was awarded the Medal of Honor and Barb received the Presidential Unit Citation. On the sub's 12th and final patrol of the war, Barb landed a party of carefully selected crew members who blew up a railroad train. This is notable as the only ground combat operation that took place on the Japanese home islands.
