The Hawk Lords are a Codex Astartes-compliant Loyalist Chapter of Space Marines and a Successor Chapter of the vaunted Ultramarines raised during an unknown Founding, though many suspect that they are a Second Founding Successor Chapter, raised from the existing veteran pilot formations of the Ultramarines 21st Chapter, who were known as "The Hawks". The Hawk Lords Chapter heavily favours the use of their various gunships, and so are unsurprisingly the undisputed masters of aerial combat amongst the Adeptus Astartes. It is not unknown for pilots from other Chapters to hone their piloting skills while on secondment to a Hawk Lords Talon Wing.
