The Ultra AC/10 is the second largest of the Ultra Autocannons. First introduced into the Inner Sphere by the Clans, Free Worlds League scientists were the first to retro-engineer the weapon and make it viable for mass-production, though the knowledge quickly spread to the other Successor States. The weapon itself is capable of firing two shots per turn, like all Ultra autocannon, resulting in doubled heat and, potentially, damage.
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/10. Experimental prototype versions of this new weapon were used during Operation KLONDIKE in small quantities. The Clan Prototype Ultra Autocannon/10 available during this period has identical stats to the Inner Sphere Ultra Autocannon/10, with the following differences: the Ultra Autocannon/10 occupies one additional critical slot, and suffers a weapon jam on a to-hit result of 2 or 3.
Ultra AC/10 is manufactured on the following planets:
|Imperator Ultra-10||Atreus||Imperator Automatic Weaponry|
|Mydron Excel||Quentin||Independence Weaponries|
|Type 9||Tamaron||Ashton 'Mech Production Complex|
The Ultra Autocannon/10 has been used in various video games, each with their own stats for the weapon; below is a list of the games that use it along with a link to each version's stats:
