The Ork Kill Kroozer is as close to a "standard" type of Cruiser as Orks get. Usually based on the hulks of destroyed Imperial and Chaos Cruisers, Kill Kroozers are protected by heavy prow armour and primarily armed with lots of Gunz and Heavy Gunz, with some also adding Torpedo Launchas to their arsenal. Kill Kroozers were a major threat to shipping in the Gothic Sector even during peacetime, and their numbers only grew during the Gothic War, presumably due to all of the starship hulks left over from the battles between Imperial and Chaotic forces. Kill Kroozers also made up a large portion of the Warlord Ghazghkull Mag Uruk Thraka's armada during the Third War for Armageddon, and as such saw action in virtually every fleet engagement of the war. They were especially pivotal during the Battle of Pelucidar when a squadron of Kill Kroozers crippled and boarded the Apocalypse-class Battleship Triumph.

Notable Kill Kroozers

• Butcher - The Butcher was the only Kill Kroozer to be repeatedly identified by Imperial Navy intelligence during the Gothic War. It is suspected that there may have been other repeatedly-sighted ships that were simply not recognized due to having undergone the large number of additions and "improvements" that are common to all Ork technology. The Butcher attacked six convoys in the Quinrox Sound over the course of the Gothic War, destroying a total of fifteen badly-needed transports, seven Escorts, and the Cruiser Admiral Lenox. It is further believed that the Butcher led the looting of Bralutha Station.
• Grimzag's Ammer - The Grimzag's Ammer fought in the Third War for Armageddon. It was destroyed by Imperial Starhawk bombers launched by the Defiant-class Light Cruisers Archangel and Forebearer while fighting over St. Jowen's Dock.
