The fusion blaster is the T’au Empire’s answer to Imperial melta weapons: a short-ranged fusion gun that turns armour into slag. It’s the go-to anti-tank pick for Crisis Battlesuits, and it’s been a staple of T’au armies since the faction’s early days.
What the fusion blaster actually does
It fires a blast of superheated fusion energy, similar in principle to Imperial melta weapons. That means it’s built for close range, where it can punch through vehicle plating rather than plink off the front.
T’au commanders typically use it to hit weaker rear armour, which is why you’ll see Crisis suits deep-striking or flanking before firing. It’s not a general-purpose gun, it’s a can-opener.
Who carries it
Crisis Battlesuits are the classic platform, kitted out as anti-tank specialists. XV25 Stealth Suits can also take one, which gives a stealth team a nasty surprise for enemy armour.
Larger battlesuits and vehicles use bigger fusion relatives like the fusion collider, fusion eradicator, and fusion cannon. Same idea, more punch.
- Crisis Battlesuits: the standard anti-tank loadout
- XV25 Stealth Suits: can swap in a fusion blaster
- Warmaker battlesuits: carry the Fusion Eliminator variant
- Vehicles: fusion cannon and other heavy fusion types
Variants worth knowing
The 9th Edition T’au codex introduced specialised fusion blaster patterns. The Alternating Fusion Blaster uses an oscillating energy wave that chains between targets, arcing secondary streams from one victim to the next.
There’s also a Dispersed pattern for wider blasts and a High-Energy pattern for focused shots. The Fusion Eliminator is a distinct weapon mounted on Warmaker battlesuits, previewed by Games Workshop in late 2025.
| Variant | What it does |
|---|---|
| Alternating Fusion Blaster | Chaining fusion streams that arc between targets |
| Dispersed Fusion Blaster | Fires dispersed blasts |
| High-Energy Fusion Blaster | Fires focused blasts |
| Fusion Eliminator | Mounted on Warmaker battlesuits |
How it fits into T’au warfare
The fusion blaster reflects the T’au approach: specialised weapons on mobile platforms, applied at the right moment. It’s not meant to trade shots at range, it’s meant to appear where the enemy’s armour is thinnest and delete something important.
That makes it a natural pairing with jump-shoot-jump tactics and deep strike. Get in, fire, get out before the return fire lands.

FAQ
Is the fusion blaster the same as a melta gun?
Functionally similar, yes. Both are short-ranged fusion weapons designed to burn through armour. The fusion blaster is the T’au version, and it’s usually mounted on battlesuits rather than infantry.
Which T’au units can take a fusion blaster?
Crisis Battlesuits are the main carrier, and XV25 Stealth Suits can take one too. Larger suits and vehicles use heavier fusion variants instead.
What’s the difference between a fusion blaster and a fusion collider?
Scale. The fusion blaster is the battlesuit-sized version, while the fusion collider and fusion eradicator are larger fusion weapons mounted on bigger T’au war machines.
