MJOLNIR POWERED ASSAULT ARMOR/V VARIANT
Yet another variant of the Mjolnir armor that has found its way into the second generation of high tech assault armor fielded by Spartan IVs, the Extra-Vehicular Activity armor’s earliest issued variant can be traced all the way back to the Mjolnir MK IV; the very first Mjolnir system ever equipped by Spartans.
With the goal of improving Spartan survivability and efficiency in zero gravity environments, the EVA armor has prove quite capable in the vacuum of space and equally well on numerous terrestrial locations.
Developed and tested by the UNSC at a Low/Zero Gravity Testing facility in Lister, Aigburth on Ganymede, the EVA armor was developed by integrating feedback on the Summa Deep Space Incident, and is also speculated to have been influenced by the brief skirmish between the UNSC Commonwealth, and a Covenant vessel in orbit above Chi Ceti IV. During that battle three Spartan-IIs, newly outfitted with the Mjolnir MK IV armor boarded the Covenant ship and attempted to detonate in from the inside. Due to Mjolnir being pushed forward by Doctor Catherine Halsey, the armor was not yet as efficient against Covenant weaponry as it would later be.
Unlike the EVA armor, the MK IV was breeched relatively easily, costing Samuel-034 his life.
The hallmark of the armor system is the wide visor, which not only greatly increases the field of view of the user, but also aids in visibility should the Spartan for any reason; leave the area of operations.
As Mjolnir advanced, so too did the EVA variant. Not long after the Chi Ceti IV incident, the MK IV version of EVA was introduced and worn by several Spartans, the most notable being Kelly-087 during a rescue mission.
That model was soon replaced by the MK V version that saw use during the Fall of Reach in late 2552 by Spartan-III, Emile-A239. With Reach glassed, all Mjolnir development was shifted to Earth temporarily. During this time the MK VI variant was completed but never saw wide spread adoption due to the limited number of remaining Spartans and the Battle for Earth taking place shortly after Reach fell.
With the Covenant War officially ending in 2553, the EVA armor was one of the few original variants that were not only continuing development, but also one of the few that were still designed and produce by ONI’s Materials Group.
