The Kumauri Empire was short-lived, quickly absorbed by the Galactic Republic, but its legacy survived in a series of massive capital ships capable of planetary bombardment, known as the Kumauri Battleship. The last line in the series was the three kilometer long Cal-class battleship. The primary weapons of these warships were mass drivers that could launch asteroids at surface targets, and were only rendered obsolete by the development of effective planetary shields.
