The Ork Deff Dread (Ork shorthand for Death Dreadnought) is a large Ork combat walker that is essentially a cross between many other combat walkers they encountered. The machine is smaller than an Ork Stompa, but is larger than a Killa Kan. The Deff Dread is also capable of carrying up to four weaponised arms. Also like a Dreadnought, a Deff Dread's Ork pilot must be cybernetically hardwired into the machine. As a result, the construction of a functional Deff Dread requires the skills of both an Ork Mekboy and a Painboy. When it is possible to craft a Deff Dread many Orks volunteer for the process since it will allow them to essentially become one of the biggest and most powerful Orks in the clan. Deff Dreads are also popular with other Orks since their immense destructive capacity, large number of weapons and tendency to stomp things to death lie at the very heart of what defines Ork "kulture."
