Autumn-class vessels are heavy cruisers, but also provide escort support when needed.
The Autumn-class heavy cruiser is a United Nations Space Command cruiser starship classification designed after the war and based on the unique design of the heavily upgraded Halcyon-class light cruiser UNSC Pillar of Autumn.
During the war, Halcyon-class cruisers performed relatively well against superior Covenant vessels, largely due to their complicated and costly design. The cost of the unique Halcyon design required to construct many of these cruisers caused NAVCOM to introduce a new, more economical, standard cruiser classification early in the war. The Navy had only a handful of cruisers by the final days of the war. One heavily modified Halcyon-class vessel (one of the oldest of its kind), UNSC Pillar of Autumn, received a wide array of upgrades prior to the failed Operation: RED FLAG near the end of the war. These upgrades allowed Pillar of Autumn not only to serve with distinction during the Fall of Reach and the Battle of Installation 04, but allowed it to go head-to-head against a Covenant Supercruiser and emerge victorious, something no UNSC ship could boast until that point. The Autumn would eventually be destroyed on Installation 04.
The heavily modified Autumn would serve as the base of the class. Several Halcyon-class hulls were used to create the first Autumn-class ships.
Following the war, the Autumn-class would form the backbone of the UNSC Navy's new fleets. The Home Fleet, decimated during the Battle of Earth and Battle of Mare Erythraeum, possessed at least ten Autumn-class heavy cruisers by early 2558, an improvement over the less than twenty Marathon-class heavy cruisers that remained Navy wide by the end of the war.
Original Pillar of Autumn SpecificationsEdit
The following were the unique upgrades given to the Pillar of Autumn, which served as a base for the design of the Autumn-class.
|Hull and Armor Overhaul||At the time of its refit, the Pillar of Autumn was equipped with 2 metres of the latest available Titanium-A ablative armor plating.|
|Triple Fusion Reactor||The Pillar of Autumn sported three Mark II Hanley-Messer rectors, which recharged the MAC and powered the ship's thrusters.|
|Magnetic Accelerator Cannon||The UNSC Pillar of Autumn used a Mark II, Light Coil - 56A2D4/MAC, which allowed the primary weapon systems to fire three times in a row without needing to recharge.|
Armament & DefenseEdit
The Autumn-class vessels feature a novel variation of electromagnetic armor that incorporates a distributed array of small shield generators, which are cheaper and easier to manufacture. When the outer Titanium-A hull plates are hit, sensors within the armor trigger the nearest generator, creating an intense, transient energy shield effect localized on the point of impact.
Drop Pod BaysEdit
On the Autumn-class existed six bays for 216 SOEIVs or cargo pods. Additional quarters and storage existed for ODSTs and their gear.
Ships of the LineEdit
- While it shares the same classification as a Marathon-class heavy cruiser, the Autumn-class is 233 metres (760 ft) longer than the Marathon-class and is a mere 93 metres (310 ft) shorter than the Valiant-class super-heavy cruiser.
