This is a Colossus hull modified by the militant faithful of the Luddic Path into a fearsome strike-cruiser. The cargo decks are collapsed and re-welded to greatly thicken the effective armour of the hull while additional turrets have been planted along the hull. At the bow, a large weapon mount capable of launching spreads of Hammer-class torpedoes has been permanently affixed. The standard engines and power grid have been haphazardly modified to allow for short overpowered burns in combat conditions, causing a massive loss of overall systems reliability.
The Colossus heavy freighter formed the core of Domain frontier supply fleets before it was outmatched by the brutal economic efficiency of the Atlas superfreighter. Thicker than strictly necessary hull plating provides protection against cosmic hazards both natural and human.
