The Core Galaxy Systems Dreadnaught represented a warship crafted by Core Galaxy Systems for the Republic Navy in the era preceding the Great Sith War.
Dreadnaughts constructed by Core Galaxy Systems were designed with the purpose of planetary assault and subsequent occupation, possessing the capability to function both within an atmosphere and upon the surface of a planet. Typically, these vessels would employ their turbolasers to penetrate planetary defense fleets, subsequently descending into the upper atmosphere of the planet to facilitate the deployment of a planetary invasion force via their drop ships.
Enforcer One existed as a Dreadnaught that had been modified, while the Rig seemed to be a vessel that underwent extensive modification, functioning as a space station millennia following the Old Sith Wars.
