The Whirlwind Hyperios is a newer variant of the Whirlwind designed to replace the Hunter variant as the Astartes' only anti-air vehicle. The Hyperios is rarer than the standard pattern Whirlwind, and its missile turret has been replaced with a battery of anti-aircraft surface-to-air missiles (SAMs) and a linked fire-control targeting Cogitator that is intended to lock on approaching enemy aircraft and bring them down. The Whirlwind Hyperios are most commonly deployed by Space Marine forces when their Thunderhawk gunships are not available to provide close air support. The Whirlwind Hyperios' missiles are able to target enemy ground targets during emergencies, and although they are not effective against heavy armour, they can still cause heavy damage to enemy light and medium vehicles.
