Unrelenting Light
Like other Space Marine chapters, the Grey Knights' primary mode of transport is the strike cruiser class of ship that is exclusive to the chapters of the Adeptus Astartes. The Grey Knights' ships however are specially modified in several ways. One is the hexagrammic and anti-daemonic wards that are built into the entire ship from bridge to landing struts and every bulkhead in between, similar to those that are placed under the skin of the Grey Knights themselves that lend the ship added protection from the forces of Chaos. Also, the Grey Knights' strike cruisers are equipped with significantly more advanced armour than the ships of other chapters. This is to allow them to close with more powerful foes and reach their destination safely since the Grey Knights have to fight more powerful enemies than the standard Adeptus Astartes chapters. Finally, the landing and drop pod bays are enlarged to be able to deploy larger numbers of marines faster.[Needs Citation]
The modifications to their ships are made possible by two factors. The first is their fortress-monastery's location in the rings of Saturn, its close proximity to Mars, the greatest Forge World in the Imperium of Man, allowing access to technology that was forgotten or is impossible to replicate anywhere else in the Imperium (this could also explain the high quality of all Grey Knights equipment). The other reason is the resources that the Ordo Malleus gives the Grey Knights due to their close working relationship as the Ordo's Chamber Militant.
