'''Defence Lasers''' are a common anti-voidship defensive weapons used by the [[Imperial]] [[Planetary Defense Force]]s. A gigantic [[laser weapon]], it is a monstrous engine of destruction so large it can only be mounted on fixed platforms. They use vast amounts of power to fire, blacking out power grids for miles around with each volley. Designed for use against invading warships in orbit, they can drive away anything up to a [[Cruiser]].{{Fn|1}}
