The Hellfire Plasma Cannonade was a Plasma Weapon system used by the ancient Deredeo Pattern Dreadnoughts of the Legiones Astartes during the Great Crusade and Horus Heresy eras. The Hellfire Plasma Cannonade was an experimental Plasma Weapon first tested on the Deredeo chassis. The Hellfire Carronade sacrifices the range of the Deredeo's standard armaments for increased armour penetration and allows for a higher rate of fire than many other Plasma Weapons used by the Imperium. The Hellfire Plasma Cannonade is still found in use by the various Space Marine Chapters and possibly the Traitor Legions that still maintain functioning Deredeo Dreadnoughts in the 41st Millennium.
