Battleships are large, heavily armed maritime vessels utilized by Bowser and his armies. Battleships are equipped with various artillery, such as cannons, Bob-omb launchers, and also Rocky Wrenches. Their texture is the same as that of the airships in Super Mario Bros. 3.
In Super Mario Bros. 3, only one Battleship fleet that guards Dark Land appears. The fleet, composed of three battleships, is stationed near the beginning of the area, just after the tank level, and is commanded by Boom Boom. Although the battleship fleet is stationed on the world map on what resembled a lava lake, the actual level depicted a brownish liquid that the player can swim in.
The battleships also reappeared in Super Mario Advance 4: Super Mario Bros. 3, in a World-e level called Koopaling Confusion. Besides the battleships themselves, it also took place in an area that resembled a port or dock, which had a short lower path and a higher longer path; regardless, the player will fight Ludwig von Koopa, though his health depends on the path chosen.
