The Autocannon is a direct-fire ballistic weapon, firing HEAP (High-Explosive Armor-Piercing) rounds at targets either singly or in bursts.

Different manufacturers and models of autocannons have different calibers (25mm-203mm) and rates of fire. Due to this, autocannons are grouped into generic "classes" of autocannons with common damage ratings, with Autocannon/2s having an extremely long range at the cost of having a very small damage output.[1]

An Autocannon/2 can use special munitions to increase its effectiveness.


The Autocannon/2 is manufactured on the following planets:
