Yamato
The Japanese Super Battleships YAMATO and MUSASHl were the largest battleships ever built by any nation. The YAMATO was completed just before the outbreak of the war in the Pacific and was Admiral Yamamoto's flagship during the Pearl Harbor attack and the Battle of Midway. The YAMATO continued to be the flagship of the combined fleet even after Yamamoto's death, but for most of the war this ship was kept almost in the backwaters of operation in the south and central pacific. It was not until the Battle of the Philippine Sea in June of 1944 that this ship was committed to action, and for the first time the US Navy got a good look at her. The MUSASHl was lost in the Battle of Leyte Gulf after taking an incredible 20 torpedoes and 10 bomb hits, even then taking over 4 hours to finally sink. The YAMATO on the other hand survived long enough to be sent on a one way mission to try and stem the tide of battle at Okinawa. The massive battleship was only 50 miles south of Japan when she was overwhelmed and sunk by US Navy aircraft, again only after taking an incredible amount of damage from torpedoes and bombs.
Bismarck
The BISMARCK & TIRPITZ were the largest and last Battleships to be completed by the German navy. At the time of their completion these were the largest, fastest and most powerful battleships in service in any of the worlds navies. The BISMARCK'S career was short and famous, her only war cruise catching the attention of almost the entire civilized world. From her quick and incredible destruction of the Royal Navy's H.M.S. HOOD until her own sinking 3 days later, almost every Royal Navy warship in the Atlantic was put on alert to help track BISMARCK down. The life of the TIRPITZ lasted a few years longer, laying in a Norwegian fjord, she successfully tied down many major warships of both the Royal and US navies that had to remain on patrol to guard against her breaking out into the Atlantic shipping lanes.
Scharnhorst
The German Battleships SCHARNHORST and GNEISENAU were the most active of all the big ships that were built by the German navy prior to the outbreak of World War Two. The SCHARNHORST was an almost constant consort of her sister ship GNEISENAU when both of these ships carried out successful anti-shipping raids out into the vast Atlantic ocean. The cost to the allies in both ships sunk as well as ships and war supplies to track them down or keep them in check, far surpassed the effort it took the Germans to construct and operate these two ships. SCHARNHORST was lost in the Battle of North Cape on 26-DEC.-1943 while trying to attack an allied convoy headed to Russia. GNEISENAU was severely damaged in drydock and never fully repaired.
