Technical specifications



The MJOLNIR Powered Assault Armor [GEN3] is the third system-wide generation of the MJOLNIR Powered Assault Armor.[2]


Early history and development[edit]

MJOLNIR Mk VI variant being assembled and marked.

Although the MJOLNIR Powered Assault Armor (GEN2) meant a radical simplification of the Mjolnir platform, to the point it could be mass-produced, some in the Spartan Operations branch were dissatisfied with its minimal performance improvement over the old GEN1 systems. By that reason, the UNSC decided to manufacture the next generation of Mjolnir armors.[3]

Around October 17, 2558,[4] the Mark VII was used as the testbed for the [GEN3] improvements, but it remained uncertain if manufacturers would adopt the standards and cost accounting by the Unified Earth Government.[2]

On February 10, 2559, four months after the rise of Cortana and the Created, the Materials Group manufactured the [GEN3] armor.[1] In October of 2559, John-117 and Blue Team were deployed on a covert mission to CASTLE Base.[5] The armor saw use during this mission.[6] Several months later on May 28, 2560, the armor was used by John-117 during a conflict on a Halo ring.[7]


Design and features[edit]

The conceptual design framework incorporates lessons from the MJOLNIR [GEN2] line of Mjolnir, while also using performance and higher levels of protection given by the MJOLNIR [GEN1] line of Mjolnir.[2]

The GEN3 armor used by the Master Chief in 2559[8] looks aesthetically similar to a MJOLNIR [GEN1] Mark IV armor variant used by some SPARTAN-II commandos during Operation: WARM BLANKET, while the helmet shares similarities with the MJOLNIR [GEN1] Mark VI helmet he used during the last months of the Human-Covenant War.[1]

Armor variants and upgrades[edit]


The following is a list of major variants of the GEN3 platform.

Armor components[edit]

  • Energy shielding: A protective barrier that surrounds the armor and protects the user from harm.[1]
  • Compact fusion reactor: The fusion reactor is the most essential part of the MJOLNIR system, as it provides power to all equipment on the armor—the reactor is built into the suit and allows for nearly unlimited movement.[1]
  • Magnetic weapon holder strips: The MJOLNIR armor features very small, yet powerful magnets placed on the legs, waist, and back of the suit that are used to hold any equipment or any weapons with a magnetic property.[1]
  • VISR[1]
  • Force-multiplying circuits[1]
  • Motion tracker: Shows movement of friendly and enemy units within the system's radius.[1]
  • Pressure seal: The pressure seal is a vital component to the MJOLNIR system, it keeps the system airtight, underwater or in space.[1]
  • Hydrostatic gel: On top of the inner skinsuit is a gel-filled layer, which regulates the temperature of the suit and can change its density to conform to the wearer's shape. The temperature inside the suit is controlled by the moisture absorbing cloth suit underneath the hydrostatic layer. The hydrostatic gel layer can also be pressurized to various levels to potentially save the wearers life should the wearer be subjected to high G forces or a high velocity impact. Spartans in Gen 3 can avoid blacking out in conditions up to 38 g.
  • SPDR counterintrusion measures: Generally placed in UNSC AIs, MJOLNIR [GEN3] is the first generation of Mjolnir armors to include them.[1] This also includes a weapon containment device, possibly to store Created AI's for later analysis.


In Discover Hope, while John-117's armor BIOS is activating, a line in the HUD reads "Preparing A.I. Intrusion countermeasures". This is likely to prevent AI intrusion following the rise of the Created.[1]
