The '''Whirlwind Artillery Tank''' is an [[Rhino]]-based artillery support vehicle. The Whirlwind along with the [[Land Raider Helios]] are the closest weapons [[Space Marine]] [[Chapter]]s use that could be considered true artillery. It is primarily used to soften up a heavily-fortified or well-defended target prior to the main attack. It mounts a [[Whirlwind multiple missile launcher]] on its turret, firing either tactical warheads or rapidly deploying minefields a variety of different missiles with the special 'Castellan' missilesdifferent purposes. The Whirlwind design is not available to [[Chaos Space Marines]], since the [[STC]] technology from which is was derived was discovered after the [[Horus Heresy]].¹ ===Varius Ammonition===The whirlwinds missile launcher is capable of firing 3 different kind of missiles²:<br />1. Vengeance Missiles: The standard explosive warhead, functions like a regular missile.<br />2. Castellan Missiles: A specially made warhead the explodes in midair at a designated spot and scatters a number of smaller mines. Used to quickly establish minefields without tideus labour.<br />3. Incendiary Castellan Missiles: A modified castellan warhead where the warhead have been fitted to scatter huge amounts of burning prometheum. This gruesome warhead is used to 'cook' enemies taking cover.<br />

The '''Whirlwind Hyperios''' is a rarer version of the standard Whirlwind, designed as an anti-aircraft vehicle. It mounts in place of the standard missile launcher, an anti-aircraft missile launcher designed to target and shoot down enemy aircraft. They are used when [[Thunderhawk Gunship]]s are not available to defend important positions from air attacks.²³
