A capital turret mounted on Khons
Often installed as defensive armaments on starships and space stations to fend off attacks from enemy capital ships, capital ship turrets (also known as capital turrets, or sometimes referred to as cap turrets) were a type of laser cannon. It is believed that they were either comparable to, or possibly a specific type of, the turbolaser.
The Trade Federation and the Sabaoth Squadron both utilized capital ship turrets in their fleets. A number of these turrets were used to defend Spacestation 1138 which was located within the Karthakk system. Moreover, each Sabaoth Destroyer was outfitted with six of these turrets, in addition to the standard laser turrets. These particular weapons presented a significant threat to Mere cruisers. During the First Battle of Geonosis, which took place in orbit, Adi Gallia and her fellow Jedi pilots prioritized the destruction of all capital turrets mounted on three Sabaoth Destroyers so that they could better assist the Mere Resistance.
