The SPARTAN neural interface is an upgrade of the standard neural interface that is used by Spartan supersoldiers.

Background

In addition to the standard functions of a neural interface, the SPARTAN neural interface is unique in that it is designed to allow an AI construct to directly interface with the Spartan's brain. Therefore, the AI resides in both the armor and the wearer's mind; essentially, it exists in both places at once. The interface allows the AI access to most of the suit's internal systems, though the Spartan has override control. The AI is capable of significantly improving the data transfer rate between the motor cortex of the Spartan and the MJOLNIR's processing unit, further improving the Spartan's already lightning-quick reaction speed. The Smart AI Black Box interfaced with Naomi-010 during their assault on the Piety, utilizing the connection to experience the world around them as the Spartan did, while simultaneously maintaining his own, objective perception via the Mjolnir's helmet cam.

The AI's data crystal chip is inserted into a socket near the base of the Spartan's skull through a slot in the MJOLNIR armor.

Like the standard-issue and command neural interfaces, the SPARTAN neural interface can probably not be removed without advanced surgery or killing the host.

Operational history

Victor-101 of Black Team was equipped with the upgrade at some point before the Battle of Line Installation 1-4, though it was most notably issued to John-117 upon his reception of the Mark V MJOLNIR armor during the Fall of Reach in August 2552 in order to allow him to mentally interface with the smart AI Cortana.

At least a few other Spartans followed suit as Naomi-010 was equipped with a Spartan neural interface by February 2553 and Frederic-104 had one implanted by July of that year. However, this was likely done in Naomi's case due to her work with Black Box as part of Kilo-Five. In Fred's case, it was in preparation for him to work with the dumb AI Damon, something that he was less than thrilled to be ordered to do due to Fred's bad experiences with Intrepid Eye.

The interface is also a standard addition to the Spartan-IVs' augmentations.

Trivia

• Despite not having been known to have received the upgrade due to the UNSC Spirit of Fire going missing in 2531, Jerome-092 was able to interface with the logistics AI Isabel during the Second Ark Conflict, particularly on their mission to destroy the CAS-class assault carrier Enduring Conviction.
