Meant for engagements in both atmospheric and exoatmospheric conditions


MJOLNIR Powered Assault Armor/Pilot is a MJOLNIR armor-compatible version of the primary helmet used by UNSC Air Force pilots developed by Chalybs Defense Solutions.[1]

GEN1 overview[edit]


Intended for engagements in both atmospheric and exoatmospheric conditions, the helmet's primary advantages are its increased field of vision and its aerospace-oriented tactical software suite incorporated to the heads-up display.[1]

Development history[edit]

The Pilot helmet entered service in 2541 and was eventually adapted for use with all UNSC armor systems, including Mark IV and eventually Mark V. It looks remarkably similar to the MJOLNIR EVA and SPI helmets.[2] While the similarities with the latter are strictly coincidental, the resemblance to the EVA helmet is a byproduct of Chalybs' collaboration with the Ganymede-based branch of the Materials Group, leading to many similarities with the EVA variant's physical architecture.[1]


It was used by the select few SPARTAN-II and SPARTAN-III supersoldiers attached to the Air Force as pilots and combat controllers.[1]

In 2558 the Pilot helmet is still being used on posters in locations like the Promesa‎ research center on Andesia.

GEN2 overview[edit]

GEN2 compatibility[edit]

As Spartan pilots use flight gear similar to those used prior to their augmentation, the GEN1 Pilot helmet could still be requisitioned by Spartans for use with their GEN2 Mjolnir suits by 2558,[3] alongside the more modern Aviator-class armor suite.[4] By 2558, the Pilot helmet was often fielded with an integral hardened uplink module and features classified updates to the UNSC Air Force-standard machine interlink firmware.[3]
