The Anvilus Autocannon Battery, also known as the Anvilus Pattern Autocannon Battery, was the main ballistic weapon system used by the ancient Deredeo Pattern Dreadnoughts of the Legiones Astartes during the Great Crusade and Horus Heresy eras. The Anvilus Autocannon Battery was a set of two Anvilus Pattern Autocannons that shared a mount and firing system.
The Deredeo Dreadnoughts were armed with two such batteries that were then twin-linked together. The Anvilus Autocannon Battery was a fearsome development of the Autocannon that was able to engage and destroy enemy armoured targets with a punishing salvo of fire. The Anvilus Autocannon Battery 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.
