"Saw one of these beauties swivel its coilguns right at a Covie destroyer trying to ram her. Those guns tore right into that bastard's hull and finished it off with a B-missile. Never seen anything like it... Shame we lost so many of her during the war."
―Navy crewman recalling her time witnessing the Epoch-class in action

The Epoch-class heavy carrier (hull classification symbol: CV) is a purpose-built fleet carrier designed to project power throughout human space without the need of extensive battle groups. The Epoch arose primarily out of the Navy's need to modernize their carrier groups where some had entered service as early as the Inner Colony Wars.

The first carriers of the class were launched in 2522, being put to the test in policing the more unruly and dangerous regions of Insurrectionist-held systems. The Epoch-class and its "sister line", the Noryang-class came at a fortunate time for the Navy, as the outbreak of the Human-Covenant War put the carriers through the wringer. In 2530, the class received a number of revisions to its design, giving the class a major face-lift in combat effectiveness. Together with its new armament and thick armored hull, the Epoch-class became a formidable foe against Covenant vessels, a rare sight at the time. Unfortunately, the carriers became a major target for the alien hegemony, with the Navy losing all but two by the end of the war.

As the prospect of peace began to settle in the minds of humanity, military analysts studied the effectiveness of the Epoch-class during the war, and recommended that the Navy extend its service life. In 2554, the Epoch-class underwent another revision, upgrading its design and specification to meet the needs of the post-War Navy. As per the Naval Procurement Acts, ten new carriers have been ordered by the UNSC Navy.
