"I reckon they call it the Osiris because no matter what you do, it won't stay dead..."
―Ensign Jacob Hansse

The Osiris-class Battleship is a heavily armed UNSC warship made for going toe to toe with vessels of similar tonnages and winning, using its heavy duty shielding, armour and weapons. The Osiris-class is exceptionally sturdy for a UNSC ship design, much akin to the Baal or Victoria class. It is honeycombed with titanium support struts along with carrying one of the most powerful UNSC shield generators, next to that found on Dreadnaughts. It ias armed in a similar fashion to Destroyers, with two prow MAC guns but is supplemented by turreted MAC guns, providing the ship with a brutal attack capability. However it does not carry any of its own escorts.

The ship is often assigned as the flagship of large fleets or as a primary protector of Super Carries, giving it heavy duty fire in exchange for fighter coverage.

UNSC Comments

"Its like someone just made a bigger destroyer. Way bigger."
