Battleship, also known as warship or warship. Historically, battleships have the characteristics of large displacement, comprehensive weapons and equipment configuration and strong weapon attack power, and are in the position of "leading boss" in naval vessels.

A warship is a heavyweight naval warship. But before 1860, the battleship was always one of the main ships of major sea power countries, so it was once called the main ship. However, with the rapid development of the army in recent years, modern weapons with the same weight and firepower are more suitable for modern operations. Therefore, this capital ship disappeared in the historical process of the development of naval vessels, and its glory was left to history forever.
