The game Star Trek: Armada has four kinds of ships, that can be considered a battleship:

Depiction	Name
	Cube
	Sovereign
	Negh'Var
	D'deridex
	Breen War Ship
	Entity
	Galor Class
	Jem'Hadar Battleship
	Ferengi Marauder
	Son'a Battleship

Battleships are the most powerful of vessels after the super weapons. They feature two conventional and one special weapon. They have the strongest shields as well but are also rather costly. (Only casters and super weapons are more expensive.) Even one or two of them can deal considerable damage if not engaged immediately.
