''Not to be confused with the [[Squats|SPESS DORF's]] [[Thunder-Fire Cannon]]. For the full page, [[Thunderfire Cannon|see here.]]'' 

The actual cannon of the Thunderfire Cannon Unmanned Ground Vehicle. This gigantic piss-off quad-barrelled cannon is a short-ranged artillery piece that is less indirect blind(-ish) firing and more in-your-face levels of FUCK OFF. It's like the [[Angry Marines]] of artillery guns. These cannons are so ECKSBAWKSHUEG that the vehicle it is mounted on is actually like, 50% of the total weapons system.

The only people even qualified of handling this thing are the [[Techmarines]]. For much added [[Lulz]], the cannon of the Thunderfire Cannon can be mounted as the primary weapon for the [[Land Raider Achilles]]. Oh yes, we know what we are all thinking. [[Meme|Yo Dawg, we heard you like artillery guns, so we put a artillery gun inside a artillery gun so you can shoot whilst you shoot!]]

The Techmarine manning a Thunderfire Cannon can set its shells to detonate in a variety of different ways, depending on the tactical situation. Surface detonations are employed against numerous enemies in comparatively clear terrain, airburst shells are used to scour a foe from cover, and the Techmarine can even program the shells to burrow deep into the ground before detonating; though the force of the blast from such Tremor Shells is greatly reduced, the resulting shockwave is sufficient to leave the foe sprawling, making them easy pickings for his brother Space Marines.

They also look similar in appearance to the Astartes Quad Launcher found on the [[Rapier Armoured Carrier|Rapier Carrier.]]
