Commandante Cappellini or Cappellini was a World War II Italian Marcello-class submarine built for the Italian Royal Navy (Italian: Regia Marina). After Italy's capitulation in 1943, the submarine, in the Far East, was captured by the Imperial Japanese Navy and handed over to Germany. Commissioned into the Kriegsmarine as foreign U-boat UIT-24, she remained in the Pacific despite failed attempts to return to Europe. At German'y surrender in May 1945, the submarine was taken over and commissioned into the Imperial Japanese Navy as I-503 and shuttled between ports as a transport submarine. At Japan's surrender in August, she was seized by the United States Navy, which scuttled her off Kobe on 16 April 1946.
