Ushuaia Armory is a defense development and manufacturing firm that produces matériel for the United Nations Space Command. It was based on the planet Reach[1] and had at least one factory on Mars.[2]


In 2535, after an unknown development period at the firm's Siófok Firing Range, Ushuaia produced the Mjolnir Powered Assault Armor/AA variant.[1] This helmet is an improved version of the helmet worn by the Orbital Drop Shock Troopers that was designed for and adopted by the UNSC Army Airborne. The helmet was also used by the Spartans, most notably Catherine-B320.

Ushuaia performed a substantial amount of work on the development of the UNSC Marine Corps Battle Dress Uniform, particularly the CH252 helmet.[1] Ushuaia may not have been solely responsible for the BDU's development, as Misriah Armory also manufactures the CH252 helmet. However, it is possible that Ushuaia developed the helmet, while Misriah is responsible for the helmet's manufacture.[3]

Ushuaia was also responsible for the development of the D96-TCE Albatross heavy dropship. The Albatross can transport large quantities of supplies, up to fifty personnel, or several vehicles. The dropship can seemingly also serve as a mobile command post.[1]

The firm also manufactures the M9 Wolverine Main Anti-Aircraft Tank.[1] In 2535, Insurrectionists bombed the Mars-based factory that produced the Wolverine. This halted further production of the unit, at least temporarily, as they are seen again in use in the Battle of Draetheus V.[2]


Ushuaia is the capital city of Argentina's Tierra del Fuego province. It is considered the southern-most city in the world.
