The Cardan II was more able to defend itself due to more room and power for additional weapons. It carried three light turbolaser batteries, three point-defense light ion cannon batteries, two proton torpedo launchers, and two tractor beam projectors. It also had more hangar space than its forebear, and could hold twenty-four starfighters. Each station could also hold four shuttles
The Cardan II supplemented older models, and was sometimes seen accompanied by starships up to 650 meters long.
The Cardan II could retain its predecessor's capabilities whilst opening up new possibilities to construct capital ships. The expanded bays of the improved station could construct two new TIE models: the TIE/sr starfighter and, potentially, the TIE Phantom, although no station actually built these. The larger construction bays allowed for more independence from more large-scale shipyards such as Kuat. Two classes of patrol vessels were taken into consideration when Kuat Drive Yards began plans for expanding the Cardan I-class space station. The Tartan-class patrol cruiser was the first option, with the second being the more-or-less outdated Acclamator II-class assault ship.
