Origin
Katie is a battleship, though it is unknown which one she is. A battle ship is a large armored warship with a main battery consisting of heavy caliber guns. During the late 19th and early 20th centuries the battleship was the most powerful type of warship afloat, and a fleet of battleships was vital for any nation which desired to maintain command of the sea. During World War II, the battleship was replaced by the aircraft carrier as the most powerful kind of warship afloat. Some battleships remained in service during the Cold War and the last were decommissioned in the 1990s. The word battleship was coined around 1794 and is a contraction of the phrase line-of-battle ship, the dominant wooden warship during the Age of Sail. The term came into formal use in the late 1880s to describe a type of ironclad warship, now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of HMS Dreadnought heralded a revolution in battleship design. Following battleship designs, influenced by HMS Dreadnought, were referred to as "dreadnoughts".
