The Berzerk type cruiser was a battlestar group support vessel in service with the Allied Fleet since the First War. These vessels serve as support to their respective battlestar groups, where two or three can be assigned at a time. The Berzerk type appears to feature similar exterior technologies as the Galactica type, with exposed ribbing and hull plating. Ships of the line also feature exposed equipment and crew areas, with many windows running along the dorsal side of the ship, a feature common to older Colonial vessels. They are about half the size of a Galactica type battlestar , and feature a similar layout, consisting of an "alligator head" fore section, a midsection consisting of the ship's hangar deck, and an aft section which houses the main sublight engines.
