Battleship
In 1906, Britain made a new kind of battleship called HMS Dreadnought. Though this ship was not much bigger, it had steam turbine engines which made it faster. All of its guns were also very large, which meant it could damage other battleships more from further away. People claimed one ship like Dreadnought could beat two earlier battleships, even battleships made just a few years before. Soon many countries were building ships like this, and calling them 'Dreadnoughts'.
