EVA-class Mjolnir (Extra Vehicular Activity), also known as the MJOLNIR Powered Assault Armor/V variant, is a MJOLNIR armor variant produced by the Materials Group. It is designed to improve the survivability of Spartans when performing extra-vehicular activity in the vacuum of space.
The EVA variant for the Mark IV still required a T-PACK for maneuvering in zero gravity. The Mark V EVA variant had a shielded visor. The Mark VI EVA variant focuses on increasing exo-atmospheric endurance and improving mobility in zero gravity without the original use of back thrusters. The helmet also contains a single-beam laser TEAMCOM system for communications.
As early as 2525 developmental Mjolnir permutations utilized physical architecture that would eventually be used for EVA. The MJOLNIR/V variant was developed and tested at a UNSC Low/Zero Gravity Testing Facility facility in Lister, Aigburth on Ganymede, integrating feedback gathered from the Summa Deep Space Incident.
The EVA variant has spawned numerous offshoots and is generally renowned for its reliability, ergonomics, and modularity— features to which the design's enduring popularity is often attributed. After the first wave of GEN2 systems, based on requests of veteran Spartan-II and Spartan-III operatives, the UNSC Ordnance Commission considered reassessing a refined and upgraded version of the Mark V EVA, specifically the customized suit worn by Emile-A239 complete with the death's head engraving on the visor. This led to the creation of the WRATH-class Mjolnir. In addition, the INDOMITABLE-class Mjolnir's right shoulder pad is based off the Mark V EVA shoulders.
On 2531, Kurt-051 used the Mark IV variant of the armor on a mission alongside Blue Team in Construction Platform 966A. A user of the Mark V variant of the armor was Emile-A239, who engraved a death's head on the visor.
The GEN2 EVA armor is similar to its GEN1 counterparts in its design. This variant's helmet uses an open-view visor system typical of EVA configurations. It has 59-L20 Aureole braces in the helmet for awareness improvement. The helmet can also be paired with all milspec hardshell and mechanical counterpressure suits.
The slim-contoured chest plate lowers physical profile dramatically. This variant also uses larger pauldrons than previous models.
Due to their long-standing history of investment Materials Group retained the production rights after the Human-Covenant War. It remains the most effective option for Spartan personnel engaged in exoatmospheric and zero-gravity scenarios. It was tested in WG/Facility 58-32/B5D.
Though EVA-class armor is fully compliant with the strictest UNSC specifications for vacuum-rated environment suits, Material Groups has continued to optimize safety and protective features relevant for combat in the harshest microgravity regimes.
The GEN1 EVA helmet remains popular as late as 2558 and can still be requisitioned by Spartans for use with their next-generation GEN2 suits.

The EVA armor's helmet is aesthetically similar to the Semi Powered Infiltration (or SPI) armor's helmet. The visor is smaller than the Mark V variant. However, the rim from the jaw down to the chin is thinner, including the breathers, and the back of the head has a quarter-sphere shape. The helmet is also much more rounded than the SPI helmet. The helmet may have its characteristic visor for complete field of vision during space operations. It vaguely resembles the Security helmet, as they both share a very large visor. Because of this, it has been dubbed the "Fish Bowl" and the "Sniper Magnet" by some gamers due to the prominent, brightly colored, spherical shape of its visor.
Unlock: Complete The Ark level on Normal, Heroic, or Legendary difficulty.
The shoulder pauldrons are larger than the standard MJOLNIR plates and feature a long attachment to their center, another similarity to the SPI armor, which could be radios. The pauldrons also cover more surface area than other shoulder pieces.
Unlock: Complete Tsavo Highway on Normal, Heroic, or Legendary difficulty.
The chest plate is a seemingly standard MJOLNIR chest plate set with a small and minor attachment. The attachment consists of a small metal plate connected to a piece of black alloy that has several unknown equipment pieces set into it. It has been speculated that the compartment on the chest plate holds a cable that could be attached to docking ports so that a SPARTAN-II does not drift into space.
Halo: Reach - Mark V GEN1
The MJOLNIR V [V] variant was developed and tested at the UNSC facilities in Lister, Aigburth, Ganymede.
CNM cost: 7000 cR, Major
UA/HUL cost: 15,000 cR, Lt. Colonel
Base cost: 120,000 cR, Commander, requires EVA base
CNM cost: 25,000 cR, Commander
UA/HUL cost: 140,000 cR, Commander
The Mk. V variant features a large visor. It bears a striking visual similarity to the SPI helmet. A second EVA helmet, EVA [C], has a skull pattern engraved on the visor. The [C] likely stands for "Custom" or "Carved".
Two upgrades are available for the helmet, the first adds a Command Network Module on the left side (CNM), and the second adds an Up-Armor plate with a Hardened Uplink Module-3rd Generation on the right side (UA/HUL).
Two upgrades are available for the [C] variant of the helmet as well, the first adds a Hardened Uplink Module on the right side (incorrectly called CNM, should be designated HUL), and the second adds an Up-Armor plate with a Hardened Uplink Module on the right side (incorrectly called HUL, should be UA/HUL). These errors likely have something to do with the [C] variant's attachments having the same names and descriptions as the standard variant.
Cost: 3,000 cR, Corporal
The shoulder pauldrons are large and bulky, being several inches thick. The attachments on the sides of the pauldrons found in Halo 3 appear to be built into them, instead of hanging out.
Halo 4 - GEN2
The helmet has a much less curved surface, with a large dip halfway down its surface, and a more flared section at the bottom.
