The Deredeo pattern Dreadnought is a dedicated heavy support frame, though it shares many core components and systems with the more general assault-based Contemptor class. Initially deployed in limited numbers to each of the Legions due to difficulties in its manufacture, its durability and firepower saw demand for the Deredeo pattern dramatically increase after the outbreak of the Horus Heresy.
The Deredeo pattern Dreadnought was in the displays at Warhammer World.
