Although Clan Snow Raven has developed numerous Zero-G and space variants of BattleArmor suits since first employing them in the Golden Century, none of these designs had been built expressly for space-born operations, either in free-flight or aboard larger vessels. In the 3060s, as the Clan began to expand out of its homeworld holdings and into the Deep Periphery, the Ravens gained access to new resources and areas of expertise, leading to the development of wholly new battlesuits.

         Although Raven scientists pursued numerous avenues of investigation, only one design-the lightweight Aerie-entered widespread use. Built with Clan technology and drawing on marine combat experience by both Snow Raven troops and their Outworlds Alliance counterparts, the suit masses just under 400-kg and is extremely swift and agile, as at-home in free-flight between orbiting vessels as it is on the ground. Its 35 kilograms of advanced armor composites provide significant protection against the hazards of space-not to mention weapons fire, though this protection is minimal compared to that available on combat-dedicated models. The suit's exoskeleton bolsters the wearer's strength, enhancing their load-shifting abilities and melee combat capabilities, but the lightweight design does not hamper freedom of movement. As such, it is ideal for close-quarters fighting aboard spacecraft (as when making or defending against boarding operations).
         The Aerie has no integral weapons but its lightweight manipulators allow the user to wield standard weapons like a regular infantryman. Raven armored infantry equipped with the Aerie generally wield laser systems, avoiding the recoil that might otherwise plague null-g operations, but troopers do sometimes employ ballistic and missile weapons equipped with recoil-suppression gear.

         Aerie use is limited to the Raven Alliance, though reports say that many Sea Fox convoys make use of them as well. They are seen by both ground forces and in space where they have proven their use and have become the favored suit in that element, presumably the reason that the Sea Foxes may have some.
