Raptorus Rex

The Raptorus Rex was a vast, mobile star fortress of the Fire Hawks Space Marine Chapter used as their primary base of operations. During the Badab War this vessel was the largest warship operating within the Badab Sector and is indeed one of the largest warships in the Imperium's service. The formidable firepower of this colossus of war was able to scour the surface of a world within mere moments or challenge a cruiser squadron alone. The Raptorus Rex along with the entirety of the Fire Hawks Chapter Fleet disappeared and was officially declared 'Lost in the Warp' following an attempted Warp jum from the Piraeus System to the Crow's Word Sub-sector in 963.M41.

History
During the Wars of Apostasy circa 378.M36, the Fire Hawks Chapter was still young. They bravely joined the stand made by the Imperial Fists, Black Templars and Soul Drinkers Chapters, along with the Martian Tech Guard against the corruption and enormities of the megalomaniacal Goge Vandire. The Fire Hawks went on to fight valiantly in many major battles against the apostate force of the insane Vandire. Their defiance was paid for with the loss of their first homeworld, Zhoros, to mass thermal bombing by the Frateris Templar fleet. Refusing to relent, the Fire Hawks helped play a key role in Vandire's overthrow, taking part in the attack on Holy Terra which finally unseated the mad High Lord. Left in tatters, the Fire Hawks' diligence and valour was not in vain, as it is believed that at this time they received command of the Raptorus Rex as a gift from the hand of Sebastian Thor himself.

The Raptorus Rex is a truly immense and ancient vessel, believed to be pre-Imperial in origin. This mighty vessel was a legend long before its involvement in the infamous conflict known as the Badab War in 904.M41. This vast, mobile star fortress served as the Fire Hawks Chapter's base. This hulking colossus of war possessed firepower enough to challenge a cruiser squadron alone or devastate the surface of a world within moments. The 'Raptorus Rex's most dreadful reputation was as a burner of worlds, its hull studded with scores of orbital bomb racks enabling it to seed a planet's atmosphere with clusters of thermic bombs. But its greatest power lay in the sheer durability lent to it by its size and ancient design, which allowed it to shrug off the heaviest fire all but unscathed and smash aside defence lines and attacking fleets with arrogant power.
