One of the known battleship classes introduced around the year 10,000 BBY, were vessels created in imitation of the long-running planet buster Kumauri Battleship line. This trend culminated with the Cal-class battleship, which was popular with several governments, most notably the Galactic Republic. These battleships were used to intimidate or destroy hostile civilizations, as the Republic aggressively expanded outward into the Galaxy. They were also effectively used as terror weapons during the Tenth Alsakan Conflict.
