Ork Kill Kroozers are built for a direct, head on attack and will seek to close the range rapidly. At close range the heavy guns which festoon the Kill Kroozer's prow and flanks can cause dreadful destruction. Add to this Orks penchant for boarding and its easy to see why the Kill Kroozer is a well know scourge of the Gothic Sector.
Heavy Ork warships were always a terror to merchant vessels plying the Gothic sector in times of peace. During the Gothic War, the number of sightings reported increased notably, presumably due to the number of hulks the Orks managed to salvage from battles between Imperial and Chaos forces. The most common style of Ork Kroozer mounts a bristling array of heavy guns and weapons batteries, mostly concentrated in powerful prow batteries.
Only one Ork Kroozer, dubbed the Butcher by Naval intelligence, was consistently identified in action throughout the Gothic War, though others may have been concealed by the constant patching and rebuilding Ork ships undergo. The Butcher attacked 6 convoys in the Quinrox Sound over the course of the war, destroying a total of 15 badly needed transport ships, 7 escorts, and 1 cruiser, the Admiral Lenox. The Butcher is also believed to have led the force that looted Bralutha Station and escaped before relief forces arrived.
