USS Razorback (SS-394), a Balao-class submarine, was the only ship of the United States Navy to be named after the razorback, a species of whale (Balaenoptera physalus) found in the far southern reaches of the Pacific Ocean. She is arguably the longest-serving combat front-line submarine still existing in the world, having been commissioned by two different countries for 56 years of active duty. She was in Tokyo Bay during the surrender of Japan. In 2004, the state of Arkansas adopted the submarine (although she was not named after the University of Arkansas Razorbacks mascot) and she is now a museum ship at the Arkansas Inland Maritime Museum.
