The Whirlwind Artillery Tank is a Rhino-based multiple rocket launcher. One of the few indirect-fire vehicles fielded by the Space Marines besides the Land Raider Helios, the Whirlwind provides accurate fire support for the suppression of numerous or highly-mobile enemies. They were used by the Allies and the Imperialists. Based upon the Rhino chassis, the Whirlwind is both fast and mobile, able to keep up with a Space Marine battlegroup.
