Battleship
Battleships were also important at the start of World War II. But by the middle of World War II, battleships had become less important than aircraft carriers. Aircraft carriers had dozens of airplanes which could drop bombs or torpedos. Even though battleships had thicker armour than ever, several hits from bombs or torpedos would still sink a battleship. The planes could fly much further than a battleship's guns could shoot. There were some important battles between battleships in World War II, but more often battleships were less important than aircraft carriers. At battles like the Battle of Taranto and the Battle of Pearl Harbour many battleships were sunk by planes.
