The Hellhammer is a super-heavy tank of the Astra Militarum that is a variant of the infamous Baneblade tank. The Hellhammer replaces the rocket-assisted Mega Battle Cannon or Baneblade Cannon of the Baneblade with a Hellhammer Cannon, a variation of the Battle Cannon commonly found on the Leman Russ main battle tank.
It has a shorter barrel with special heavy-gauge suppressors built into it that allows it to fire extremely high-calibre shells without ripping itself apart. These shells are designed to destroy armour and emplacements with an unstable sub-atomic charge.
