Rotary AutoCannons

Rotary AutoCannons, or RACs, are ballistic weapon systems capable of producing high rates of fire and DPS.

Overview

A pre-0.6.0 Uziel B shows off the RAC2.

The Rotary AutoCannon make use of multiple barrels, allowing for a higher rate of fire by giving each individual barrel some time to cool down, resulting in a relatively high caliber gatling gun. Compared to their Standard AutoCannon or Ultra AutoCannon counterparts, the RACs can deal signifigantly more damage per second but this quality comes with reduction in range. Even with their multiple barrels RACs are prone to overheating under sustained fire, so short cooling breaks between bursts are recommended for optimal damage dealing.

Only Inner Sphere assets and the Lobo C use Rotary AutoCannons.

Gameplay & Hints

RAC2 and RAC5

• RAC2 and RAC5 both have a short spin up time (about 1 second) before the bullets start fying. The weapon also cools during the spin-up.
• Kinetic damage does some bonus damage to air units.

Canon

Rotary AutoCannon

The Rotary AutoCannon was developed by the New Avalon Institute of Science in 3062 and is both bulkier and heavier than Ultra-class AutoCannons. In addition, the expense of construction and inability to make use of specialty munitions have prevented it from being developed for the heavier AutoCannon calibers. Offsetting these factors, however, are the RAC's ability to fire at up to six times the rate of a Standard AutoCannon. While the weapon is prone to jamming at higher rates of fire one significant improvement over Ultra AutoCannon is the ability to clear the jam in the heat of battle.

Although initially developed and produced by the Federated Commonwealth, the FedCom Civil War saw the RAC quickly disseminate to other Successor States. Currently the Clans have yet to develop an RAC of their own.
