Developed in 3062 by the Federated Commonwealth, the Rotary Autocannon/5 is based only loosely on the Autocannon/5. 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 up to three times the damage of even an Ultra AC/5. The weapon may be used 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 the Ultra autocannon, Rotary autocannons are unable to make use of special munitions.[2]

Clan Diamond Shark's engineers created their own version of the RAC/5 in 3069.[1]
