Description[edit]

The Ultra AC/20 (also UAC/20) was the largest bore Ultra autocannon. Like all Ultra autocannons, it was capable of twice the rate of fire of a standard autocannon, doubling its heat output and—potentially—its damage. Only the Clan HAG 40 could match the sheer damage output of the Ultra AC/20. The only weapons capable of delivering more damage to one location were the heavy Gauss rifle and the experimental improved heavy Gauss rifle.

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 AC/20. Experimental prototype versions of this new weapon were used during Operation KLONDIKE in small quantities. The Clan prototype Ultra AC/20 available during this period had identical stats to the Inner Sphere Ultra AC/20 required additional mounting space and was more prone to jamming.[3]

The Ultra AC/20 was used on the following planets in the Inner Sphere:
