“
Autumn-class vessels are heavy cruisers, but also provide escort support when needed.[2]
”


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.

The Hull classification symbol for ships of the Autumn-class was CA.[3]

Class HistoryEdit

OriginsEdit

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.[3]

Active ServiceEdit

Following the war, the Autumn-class would form the backbone of the UNSC Navy's new fleets.[4] 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,[5] an improvement over the less than twenty Marathon-class heavy cruisers that remained Navy wide by the end of the war.[6]

DesignEdit

The Autumn-class was manufactured by Sinoviet Heavy Machinery[1][3] in orbit of a planet, including Earth.[7]

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.[1]

Upgrade Purpose
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.[8]
Triple Fusion Reactor The Pillar of Autumn sported three Mark II Hanley-Messer rectors, which recharged the MAC and powered the ship's thrusters.[8]
Magnetic Accelerator Cannon The UNSC Pillar of Autumn used a Mark II, Light Coil - 56A2D4/MAC,[8] which allowed the primary weapon systems to fire three times in a row without needing to recharge.

Armament & DefenseEdit

ShieldingEdit

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.[3]

LayoutEdit

HangarEdit

The Autumn-class has a hangar at the bottom of the ship. This hangar can hold at least six D79H-TC Pelicans.[5] The hangars are modular and can be swapped out for different packages.[3]

Drop Pod BaysEdit

On the Autumn-class existed six bays for 216 SOEIVs or cargo pods. As well, some quarters existed for the ODSTs and their gear.[3]

ComplementEdit

The orbital assault and strike configuration of the Autumn-class had 45 Marines and 220 Orbital Drop Shock Troopers. The ship usually carries 12 of either the D77-TC or D79H-TC Pelicans.[3]

Ships of the LineEdit

At least 13 Autumn-class ships are known to exist by 2557.[9]
