A Chaos Sonic Dreadnought armed with Sonic Weapons and a Dreadnought Chainfist

A Sonic Dreadnought, also referred to as a Slaanesh Sonic Dreadnought, is a variant of the Chaos Dreadnought used by the Traitor Legions of Chaos that is dedicated to the service of Slaanesh, the Chaos God of pleasure and excess. The Sonic Dreadnought is used almost exclusively by the Emperor's Children Traitor Legion and their many fragmented warbands.

The Sonic Dreadnought differs from other Chaos Dreadnoughts in that its standard main armament is replaced with the Sonic Weaponry often favoured by the servants of the Prince of Pleasure. During combat, the Sonic Dreadnought moves across the battlefield continuously broadcasting discordant howling and screams of ecstasy and madness, driving its enemies insane or killing them with the power of extreme sound. These Dreadnoughts are usually sighted fighting alongside Chaos Noise Marines whilst on the battlefield.


A Sonic Dreadnought armed with a set of twin-linked Sonic Blasters, a hull-mounted Heavy Flamer, a Dreadnought Chainfist, Dirge Casters, and Smoke Launchers.

The Sonic Dreadnought replaces the standard weapons of a Chaos Dreadnought with that of Sonic Weapons. In place of the standard long-ranged weapon arm of the Chaos Dreadnought there is a set of twin-linked Sonic Blasters or a single Blastmaster. The Dreadnought retains the standard Dreadnought Close Combat Weapon located on its other weapon arm, usually making use of a Dreadnought Chainfist with a hull-mounted Heavy Flamer.

The Sonic Dreadnought is also usually armed with a Doom Siren mounted within its modified face plate, which can be used alongside the hull-mounted Heavy Flamer and is also used during close-combat. The Sonic Dreadnought is often outfitted with a set of Dirge Casters or Warp Amplifiers located on the top of the Dreadnought's chassis.

It is unknown if the walker can be armed with any Dreadnought Close Combat Weapons like a standard Chaos Dreadnought or if it can only use a Dreadnought Chainfist. The Sonic Dreadnought can, however, be outfitted with standard Chaos Dreadnought upgrades and attachments such as smoke launchers, extra armoured plating, and a searchlight.

Lament of the Damned

There exists a Chaos Dreadnought battle formation used by the Forces of Chaos known as the Lament of the Damned. This formation is made up of at least three Chaos Sonic Dreadnoughts and can contain as many as nine. The Dreadnoughts are led into combat by a fallen Chaos Lord or Chaos Champion of Slaanesh who has been eternally enslaved within a Dreadnought frame and daemonically-possessed through the enactment of occult rituals.

The combined effects of the Sonic Dreadnoughts' many Dirge Casters and Sonic Weaponry can drive even the hardiest of enemies insane merely by being within proximity to the Dreadnoughts, as reality itself rebels and begins to mutate under the power of their Warp-fueled assault. This formation is known to have been used by the Exquisite Host Chaos Space Marine warband during the 13th Black Crusade of Abaddon the Despoiler in 999.M41.
