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.^[4][5]

GEN1 overview[edit]

Design details[edit]

The EVA variant for the Mark IV still required a T-PACK for maneuvering in zero gravity.^[4] The Mark V EVA variant had a shielded visor.^[1] The Mark VI EVA variant focuses on increasing exo-atmospheric endurance and improving mobility in zero gravity without the original use of back thrusters.^[5] The helmet also contains a single-beam laser TEAMCOM system for communications.^[4] The EVA helmet is capable of supporting AN/PCK-221 FARNDALE and AN/PCK-221 FARNDALE Command Network Modules, COURIER PEARL Hardened Uplink and Type C1 UA module.

Development history[edit]

As early as 2525 developmental Mjolnir permutations utilized physical architecture that would eventually be used for EVA.^[7] 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.^[1][8][2]

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. The GEN1 EVA helmet remained popular as late as 2558 and could still be requisitioned by Spartans for use with their next-generation GEN2 suits.^[9] 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.^[10]

As late as 2560, the GEN1 EVA helmet and shoulders could still be requisitioned by Spartans, upgraded to be roughly equivalent to GEN3.^[11]

Usage[edit]

On 2531, Kurt-051 used the Mark IV variant of the armor on a mission alongside Blue Team in Construction Platform 966A.^[4] A user of the Mark V variant of the armor was Emile-A239, who engraved a death's head on the visor.^[1]

GEN2 overview[edit]

Design details[edit]

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.^[3] The helmet can also be paired with all milspec hardshell and mechanical counterpressure suits.^[14]

The slim-contoured chest plate lowers physical profile dramatically. This variant also uses larger pauldrons than previous models.^[3]

Development history[edit]

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.^[3]

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.^[14]

Usage[edit]

Spartan Kelly-087 used this armor during Operation: RETRIBUTION on December 2553.^[15]

In-game information[edit]

Halo 3 - GEN1 Mark VI[edit]

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. 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.

In the Halo: The Master Chief Collection edition of Halo 3, the EVA armor (like all original Halo 3 permutations) is unlocked by default.

Helmet	Description	Unlock requirements (Halo 3)	Unlock requirements (Halo: MCC)
EVA	Helmet: The Mjolnir/V variant was developed and tested at UNSC facilities in Lister, Aigburth on Ganymede, integrating feedback gathered from the Summa Deep Space Incident.	Unlock Campaign Complete: Normal achievement.	Unlocked by default.

	MCC: EVA variants emphasize improved mobility and endurance in zero gravity, without the use of thrusters.	N/A

Halo: Reach - GEN1 Mark V[edit]

The Mark V variant features a large visor and 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". The HUL attachments to the EVA[C] helmet appear to be mislabeled: it is mislabeled as CNM in the first upgrade, and then mislabeled as HUL[3] in the second upgrade. These errors are likely related to the [C] variant's attachments having the same names and descriptions as those of the standard variant. 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.

All EVA armor types can be unlocked in the Halo: Reach's Armory through the game's purchase system via the use of cR. In Halo: The Master Chief Collection, the EVA set is attainable in the Season 1: Noble progression system.

Halo 4 - GEN2[edit]

EVA was one of the armor permutations to return, albeit completely redesigned for GEN2, in Halo 4. In The Master Chief Collection, the EVA set and its Breach (BRCH) skin variant are available by default.

Halo 5: Guardians - Upgraded GEN1 and GEN2[edit]

The Halo 4 design of EVA returns in Halo 5: Guardians. The helmet and body armour are unlockable through the Requisition system. The body armor includes the Recon chest and shoulders, the Ricochet forearms and Recruit legs. The GEN2 EVA set has four skins: Hadfield, Leonov, Solovyev, and Zhigang. The Memories of Reach update saw the addition of the WRATH helmet, based on Emile-A239's customized EVA helmet seen in Halo: Reach. The Classic Helmet REQ Pack added the GEN1 Mark V design from Halo: Reach.

Trivia[edit]

• The EVA helmet bears a resemblance to the Apollo Program's A7L PGA pressure helmet, which was called a "fish bowl" by the astronauts and support staff.
• Through the Career section of Halo Waypoint, a player that has achieved Milestone 50 (3900 achievement points on all Halo titles) will receive an EVA helmet for their Xbox LIVE avatar.
• The four skins for EVA in Halo 5: Guardians are named after astronauts Chris Hadfield, Alexey Leonov, Anatoly Solovyev, and Zhai Zhigang. Each astronaut is known for their EVA work: Leonov was the first person to perform a spacewalk; Solovyev holds the record for most spacewalks (16) and most time spent in EVA (over 82 hours); Hadfield and Zhigang were the first citizens of their countries (Canada and China, respectively) to perform spacewalks.
