Devana-class battlecruiser

The Devana-class battlecruiser (hull classification symbol: CB) were a class of early MAC-armed capital ships employed by the UNSC Navy in the Cold War, Insurrection, and early Great War. Designed to destroy the new generation of cruisers, the Devana-class was built to counter what would become the Hades-class heavy cruiser of the CMA. Fast enough to catch cruisers, and with a MAC that was one of the most advanced of the time. The power and range of the gun allowed it to deal with all but the heaviest of spatial combatants. The Devana-class would first enter service in 2482 with the UNSC planning on build 48 ships of the class. It's first decade of service would be marred by technical issues leading to the UNSC only commissioning half of the initially planned ships. Although the technical problems would largely be resolved by the end of the 2480s, the ships would remain stigmatized as poorly built.

The class would not see much action during the Insurrection despite heavy deployments throughout the Outer Colonies. As dedicated spatial combatant it lacked a large troop complement, although it did provide a good showing in the few space battles it participated in. However, by the 2510s the ship was an aging platform, combined with little need for a ship of its type, the decision was made to decommission the class. With the last ships exiting service and being transferred to the Reserve Fleet in 2521. The class would reenter service in 2526 soon after the outbreak of the Great War.

17 of the ships were considered in good enough condition to fight and underwent modernization programs to bring them up to standard. Notably modernizing its MAC to retain its battlecruiser classification. The ship’s refits meant it missed the Second Battle of Harvest. The class would see service in the latter part of the Harvest campaign, with its significant successes in ambushing Covenant logistics vessels and lone capital ships. Despite these successes the ships would be pulled back for defensive deployments as the Covenants campaign into the Outer Colonies intensified. The Devana would participate in the Battle of Chi Rho with all but 3 ships surviving to retreat to the Inner Colonies, and were ultimately decommissioned and scrapped.
