Description[edit]

The Ultra AC/20 is the largest bore Ultra Autocannon. Like all Ultra autocannons, it is capable of twice the rate of fire of a standard autocannon, doubling its heat output and, potentially, its damage. Only the brand new Clan HAG 40 can match the sheer damage output of the Ultra AC/20, though even that cannot place 20 points of damage squarely in a single target area. The only weapons that are capable of delivering more damage to one location are the Heavy Gauss Rifle and the experimental Improved Heavy Gauss.

Variants[edit]

In the years between the Second Exodus and the beginning of Operation KLONDIKE the nascent Clans began development of what would become the Ultra Autocannon/20. Experimental prototype versions of this new weapon were used during Operation KLONDIKE in small quantities. The Clan Prototype Ultra Autocannon/20 available during this period has identical stats to the Inner Sphere Ultra Autocannon/20, with the following differences: the Ultra Autocannon/20 occupies one additional critical slot, and suffers a weapon jam on a to-hit result of 2 or 3.[3]
