Officially classified as a type of command [[Battle Barge]], the vessels were around 20 kilometres in length, though their size and appearance varied greatly.{{Fn|1}} These massive ships were frequently used as flagships for Imperial fleets and even [[Primarch]]s. The Gloriana Class vessels are the largest known Imperial warships after the ''[[Phalanx]]'' and [[Furious Abyss]]-class vessels.{{Fn|1}} Some of the largest known Gloriana-class vessels were the ''[[Vengeful Spirit]]'', ''[[Conqueror (Ship)|Conqueror]]'', ''[[Hrafnkel]]'', and ''[[Iron Blood]]''.{{Fn|4}}

The [[Dark Angels]] had perhaps the greatest fleet of the Space Marine Legions during the time of the [[Horus Heresy]], including many advanced relic ships which had been granted to them by the Emperor, among these were a fleet of Gloriana Class vessels.{{Fn|10c}} These vessels, or other first-rate warships, formed the core of many of the Dark Angels Support flotillas.{{Fn|10c}} During the [[Rangdan Xenocides|First Rangdan Xenocide]] at the [[Battle of Advex-Mors]] the leading squadron of the Dark Angels fleet fielded no less than three Gloriana class vessels, the ''[[Invincible Reason]]'', the Legion’s flagship, ''[[Truth's Razor]]'' and the ''[[Paradigm of Hate]]'', which would later sacrifice itself to destroy a [[xenos]] war-moon.{{Fn|10e}} Later two unnamed Dark Angels Gloriana Battleships were seen during the [[Thramas Crusade]],{{Fn|10a}} and another unnamed First Legion Gloriana battleship was present during the [[Sealing of the Black Gate]].{{Fn|10d}}
