The Autumn-class heavy cruiser is a class of capital ship in service with the UNSC Navy, with members of this class given the hull classification symbol of CA. Manufactured by SinoViet Heavy Machinery, these heavy cruisers mostly fulfill attack or command roles within the fleet, though some also provide escort support when needed. Commissioned following the end of the Human-Covenant War to form the core of the reconstituted UNSC Navy’s task forces, the Autumn-class was designed to be the successor for the Marathon-class and the Halcyon-class, as most cruisers of those classes were destroyed or decommissioned in the war.

The name behind the Autumn-class is derived from the colloquialism for that of its lead ship, which in turn is named for the legendary Halcyon-class UNSC Pillar of Autumn. Adapting the improvements and modifications made to Pillar of Autumn for Operation: RED FLAG in 2552, the Autumn-class heavy cruiser represents a considerable leap forward in human warship design, a testament to the UNSC's modern technological prowess.

Overview

Superstructure and hull

As the first ships of the class were built on the recycled hulls of Halcyon-class light cruisers, the hull of the Autumn-class superficially resembles those of the Halcyon-class that preceded it. Additionally, a number of improvements and modifications tested on the UNSC Pillar of Autumn for Operation: RED FLAG were incorporated into the Autumn-class by SinoViet Heavy Machine
