Prinz Eugen was an Admiral Hipper-class heavy cruiser, the third member of the class of five vessels. She served with the German Navy (Kriegsmarine) during World War II. The ship was laid down in April 1936 and launched in August 1938; Prinz Eugen entered service after the outbreak of war, in August 1940. The ship was named after Prince Eugene of Savoy, an 18th-century Austrian general.
Prinz Eugen saw extensive action during Operation Rheinübung, an attempted breakout into the Atlantic Ocean with the battleship Bismarck in May 1941. The two ships engaged the British battlecruiser Hood and battleship Prince of Wales in the Battle of Denmark Strait, during which Hood was destroyed and Prince of Wales was severely damaged. Prinz Eugen was detached from Bismarck during the operation to raid Allied merchant shipping, but this was cut short due to engine troubles. After putting into occupied France and undergoing repairs, the ship participated in Operation Cerberus, a daring daylight dash through the English Channel back to Germany. In February 1942, Prinz Eugen was deployed to Norway, although her time stationed there was cut short when she was torpedoed by the British submarine Trident days after arriving in Norwegian waters. The torpedo severely damaged the ship's stern, which necessitated repairs in Germany.
Upon returning to active service, the ship spent several months training new officer cadets in the Baltic before serving as artillery support to the retreating German Army on the Eastern Front. After the German collapse in May 1945, the ship was surrendered to the British Royal Navy before being transferred to the US Navy as a war prize. After examining the ship in the United States, the US Navy assigned the cruiser to the Operation Crossroads nuclear tests at Bikini Atoll. After surviving both atomic blasts, Prinz Eugen was towed to Kwajalein Atoll where she ultimately capsized and sank in December 1946. http://en.wikipedia.org/wiki/Operation_Crossroads
