Battleship
After World War II there was not much point to a battleship. Aircraft carriers had become even better, because of jet aircraft and missiles. Also, even a heavily armored battleship could be sunk by a nuclear bomb. Even so the United States Navy kept a few battleships during the Cold War. The very big guns on a battleship were still useful to shoot at shore targets if there was an invasion from the sea. American battleships were also given new weapons like guided missiles to make them more useful if there was a war with Russia. However, only the United States could afford to keep battleships like this. No-one else did. Some American battleships shot at Iraq in the Gulf War. This was the last time when any battleships fought. The United States kept battleships until 2004, when the last ones were made into museums.
