The German heavy cruiser Prinz Eugen was the famous companion of the famous battleship Bismarck in 1941, but would go on to serve the Kriegsmarine until the end of the war. Transferred to the US Navy as a war prize, she would end her days at Kwajalein Atoll in the Pacific after surviving two nuclear explosions.

Originally intended to be the third of the Yamato Class Battleships, the Shinano was the largest aircraft carrier ever built until the US nuclear carriers in the 1960s. She also remains the largest ship ever lost to a submarine in combat.

The USS Housatonic was an Ossipee Class Sloop of the United States Navy that operated during the American Civil War. She is best known for ending her brief and otherwise successful career by becoming the first victim of a submarine attack in history when she was sunk in 1864 by the Confederate sub HL Hunley.
