Vortex Warhead

The Vortex Warhead (also called Vortex Missile) is an extremely rare and advanced type of specialised ordnance used only in the direst circumstances by the Imperial Guard, the Titan Legions or the Imperial Navy. The weapon looks like a large ballistic missile mounted either on a Titan weapon hardpoint, or a Deathstrike Launcher. The payload of the weapon is no mere explosives, bu a complicated mechanism which shows many similarities with the Warp Drives that equip the Imperium's starships. Once activated, this mechanism opens a "hole" to the Warp in realspace, which utterly annihilates anything caught in its area of effect.

Vortex weapons are extremely difficult to construct, and is also fickle and unpredictable. Indeed, once opened, the Warp vortex can drift randomly around, sustaining itself on the present Warp energies, and annihilating friend and foe alike. Vortex Warheads are only deployed and used with special authorization from the Adeptus Munitorum, and only when the Imperial commanders are past any consideration of collateral damage.
