Description[edit]

The LB 20-X AC was the autocannon with the largest bore capable of firing LB-X cluster rounds. Its slug round could deal a devastating amount of damage to one location, while its shotgun-like cluster munitions delivered 20 different projectiles to the target, an effect that was described as similar to a sandblasting. Unlike the lighter-bore LB-X autocannons, the battlefield specs of the 20-class were identical between the Inner Sphere and Clan versions, the only differences being in size and weight. The cluster munitions also made it easier to hit and performed well as flak, making it lethal when used against VTOLs. In addition, like other 20-class autocannons, the LB 20-X AC could be split among BattleMech locations.[2]

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 LB 20-X. Experimental prototype versions of this new weapon were used during Operation KLONDIKE in small quantities. The Clan Prototype LB 20-X available during this period had identical stats to the Inner Sphere LB 20-X autocannon, other than that it required additional mounting space.[8]

Models[edit]

The LB 20-X AC was manufactured on the following planets:

Defiance Disintegrator[edit]

The Defiance Disintegrator had a caliber of 200 mm. What was referred to as a "solid slug" round was actually a standard high-explosive armor-piercing round.[9]
