A Thunder Hammer is a melee Power Weapon often employed by Loyalist Space Marines of the Imperium of Man and by some Chaos Space Marines as well. Thunder Hammers are primarily used by Astartes encased in Terminator Armour when they serve as melee-focused Assault Terminators, though they have also been wielded by those in regular power armour with access to the relevant Armoury. Patterns of Thunder Hammer also exist that can be wielded by unaugmented Humans such as Inquisitors of the Ordo Malleus and members of the Adeptus Ministorum.

This large warhammer incorporates an energy field emitter within its head that activates only when the hammer strikes its target. This allows the weapon to store a tremendous amount of energy and release it only at the moment of impact, producing a terrific blast of energy and concussive force like the crack of thunder, from which the name of the weapon originates.
