Able to target and destroy the foe at close range the Contemptor-Mortis was outfitted with an advanced Helical Targeting Array that allowed it to provide a Space Marine spearhead force with close anti-air support when needed. During the last years of the Great Crusade, the Contemptor-Mortis sub-pattern was widely used by both the Dark Angels and Iron Warriors Legions, although it was used to some extent by all of the Legiones Astartes during this era. Ten millennia later, there remain several Contemptor-Mortis Dreadnoughts that are still operational. They are revered both as potent relics of the Imperium's Golden Age and as powerful weapons by those few Space Marine Chapters lucky enough to still possess them.
