{{ImperialGuardPortal}}{{stub}}The '''Hellhammer Cannon''' is a heavy version of the [[Battle Cannon]] mounted on a [[Hellhammer]]. It has shorter barrel with heavy-gauge suppressors to fire extremely high -calibre shells. This allows it to fire without ripping itself apart. The shells are designed to destroy armour and emplacements with an unstable sub-atomic charge.^{{Fn|1}}
