The Gloriana -class Battleship was a massive class of Imperial Battleship constructed during the height of the Great Crusade and were operational from the late 30th Millennium into the early 31st Millennium during the Horus Heresy.
Each of these mighty vessels was highly individualistic and unique from
one another in both form and armament. During the Great Crusade each
individual Space Marine Legion acquired at least one such vessel which inevitably became the Legion's flagship, utilised by their respective 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 any other known class of Imperial vessel, with the two exceptions
of the mobile star-fortress known as the Phalanx used by the Imperial Fists Legion and the Abyss-class Battleships unleashed by the Word Bearers Traitor Legion during the Heresy. The largest of these vessels, the Macragge's Honour , is twenty-six kilometers in length, while the Shield of Cydonia is twenty-two kilometers in length. As expected of such monumental warships, the armor 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 Horus Heresy. During the
conflict several of these ships were destroyed in combat but because of the
ailing state of the Imperium following the galaxy-wide rebellion, which
cost the galaxy dearly in both blood and treasure, the Mechanicum's shipyards were unable to continue producing such powerful and advanced vessels. The Shield of Cydonia was the flagship of the Sons of Athena. A substantial number of decks of the great vessel have been dedicated to medicae and laboratoriums filled with cloning tanks and stasis chambers for the purpose of force growing specialized Gorgonseed Progenoid Glands that can be implanted into either male and female humans that have received the Athenian retrovirus serum. The serum was the key to the genetic engineering program instituted by the Legion's Primarch, and the cause of her downfall. The Shield of Cydonia also contains the remnants of the Legions war gear: including six Devourer dropships, one hundred Jetbikes, sixty-four Land Raider tanks and one Malcador super heavy tank, as well as four remaining Virus Bombs and six Vortex torpedoes in its torpedo bay (which has room for a maximum of sixteen torpedoes or bombs in total; twenty if four were left in the tubes, logs mention that it originally carried ten Virus Bombs, five were employed during the Great Crusade). The Shield of Cydonia 's prow launch bay is so large that it may fit four voidships of frigate class or smaller, and its port and starboard launch bays each house three of its Devourer dropships in addition to a total of two wings of Marauder bombers capable of functionally in atmosphere or space. In its day the vessel carried five hundred Space Marines, all their support auxiliaries, vehicles and equipment. It still contains nearly one hundred suits of 'Crusade' model mark one power armor and suitable weapons for a legion of super warriors. Lastly, the Shield of Cydonia is outfitted with an archaeotech Castellan-pattern triple voidshield array that includes multiple redundant systems and an overload capacitor fail safe system that allowed it to automatically restore an overloaded voidshield up to three times per day, it could also effectively double its voidshield rating for a single strategic turn (from 3 to 6, although it also doubles the power consumption from 9 to 18), although on the strategic turn immediately following the array has one less shield available due to the strain placed on its emitters, one shield emitter must be taken offline to avoid being damaged.The overload capacitors are currently damaged, requiring exotic materials not found on board to repair, the void shield generators suffered battle damage the last time they were employed which the heretics guess was during the Great Crusade, evidence remains that partial repairs were conducted so it wasn't difficult to bring the primary void shield online with a little effort on the part of the traitorous Crimson Guard repair crews, the secondary and tertiary shields remain damaged along with the overload capacitors which are an archaeotech component that doesn't look like a simple fix (-50 to Tech-Use tests even if the necessary parts are acquired).

the black between stars, and was missing its main plasma engines.
According to the ships log the drive had been jettisoned to avert the
destruction of the battlecruiser after it sustained catastrophic damage.
The heretics later retrofitted it with the plasma drive from a crippled
Imperial Navy light cruiser. In its hey day, the ships drive would have produced ~100 units of power every hour, and the vessels systems would have consumed nearly all of it when in battle.
