Their precise capabilities are unknown, but the ships of the class were outfitted with Chiss versions of the range of equipment found aboard a typical Star Destroyer. Like most Star Destroyer designs, the Chiss capital ships were powerful, but were also vulnerable to a concerted starfighter assault. The most prominent feature was a large dome amidships, thought by observers to house cloaking equipment, but for the most part the planes of the armoured hull were as blank as an expanse of duracrete, interrupted only by recessed weapons mountings. One distinct difference from most Star Destroyers was that the type lacked any obvious command superstructure, apparently in an attempt to deny attackers easy and visible targets.

The Chiss Star Destroyer somewhat resembled the 900m Victory-class Star Destroyer design, but its gray hull was slightly longer and slimmer, giving it an aggressive, needle-shaped appearance.
