Gloriana-class Battleship

The Gloriana-class Battleships were among the largest warships in the Imperium, and perhaps the most powerful vessels in the Galaxy during the Great Crusade and the Five Ruins. It is believed that one was constructed for each of the Legiones Astartes, to serve as the flagships of their Primarchs. This role was due to these warships incredible array of firepower which allowed them to single-handedly batter entire fleets or recalcitrant planets into submission. These warships were far larger than other known class of Imperial vessels, with perhaps only a few exceptions.

As expected of such monumental warships, the armour of the Gloriana-class was incredibly thick and protected by overlapping Void Shields which allowed them to absorb stupendous amounts of damage. During the Great Crusade, these warships helped the Legiones Astartes swiftly conquer and bring newly-discovered worlds into Imperial Compliance, which helped to establish the nascent Imperium of Man and its domination of the known galaxy. These vessels were effective at sundering numerous xenos fleets and were put to similar use during the Ruins.
