Rotary AC/2

Developed in 3062 by the Federated Commonwealth, the Rotary Autocannon/2 is based only loosely on the Autocannon/2. While it has the same bore, it is capable of firing up to six times as many rounds as its standard cousin, allowing it to deal three times the damage of even an Ultra AC/2 (while the Inner Sphere variants suffer from a minor drop to effective range). The weapon may be use to fire up to six times in a turn, with each additional shot giving the potential for increased damage. At the same time, each extra shot increases the amount of heat the autocannon builds and increases the chance for a jam. Like Ultra autocannons, Rotary autocannons are unable to make use of special munitions.

Clan Diamond Shark's engineers created their own Clan-tech version of the RAC/2, starting development in 3069, producing prototypes in 3073, and finally starting line production in 3104 with the Clan-RAC/2 becoming widely available by 3145.
