It consisted of four laser cannons which could be fired alternately in pairs or individualy in rapid succession, making them ideal for starfighter defense. They were very powerful compared to other ship-mounted weapons, and more affordable as well. They varied in size, from the relatively small versions mounted on the Millennium Falcon to larger variants mounted on smaller warships like the Lancer-class frigate. K-wing assault fighters were armed with quad laser cannons. An example of the quad laser cannon was the AG-2G quad laser cannon, of which the Millennium Falcon had two.
