Fusion Cannon

A Fusion Cannon is a Tau weapon that is a larger versions of a Battlesuit-mounted Fusion Blaster. A Fusion Cannon is a form of Melta Weapon, and fires blasts of energy which can reduce even the most heavily armoured vehicles or fortifications to slag in the blink of an eye. Fusion Cannons have an extended range compared to a Fusion Blaster, and also have a blast radius that allows them to destroy closely packed groups of enemy vehicles and heavy infantry. Hammerhead gunships are the only Tau unit able to be armed with Fusion Cannons, as they can be mounted as a twin-linked primary turret weapon system in place of a more common Railgun or Ion Cannon.

Fusion Cannons were first encountered by the Imperium during the Taros Campaign, where Imperial tacticians believe the weapons were being field-tested for the first time.
