ORS-class heavy cruiser (EXverse)

The ORS-class heavy cruiser is one of the most powerful Covenant ship still active with various Covenant remnant groups. Built using Forerunner technologies such as a weapon core, its importance within the Covenant fleet was so high that its deployment could be authorized only by Hierarchs.
This class of cruisers took part to the Human-Covenant War only in small numbers, often to lead small battlegroups. As such, only nineteen were lost in the war, less than the half involved. After the war these powerful vessels fell into various Covenant splinter factions' hands, as each of these knew how much useful could be an ORS cruiser, and their still relevant number was a major threat to the UNSC, to the point that ONI tried to track every cruiser until the rise of the Created.
