The Battleship is a naval unit. Heavily armored and slow, its twin cannons are very useful for bombarding ground installations, but it is of limited use against ground or sea targets.
The Battleship was planned be replaced by faction-specific capital ships in 2.0, but the navy as a whole was scrapped prior to the release of 1.85 due to technical issues. However, naval warfare is still available as an optional expansion for the mod.
