When the cruisers come under fire from plasma weaponry, the titanium slabs boil off, sparing the internal structure, weapons, and crew from critical damage until it is eroded away. Much of the resiliency these cruisers' display comes from the installation of thick plates of Titanium-A armor. The Autumn-class heavy cruiser is a well-rounded capital ship, striking a balance between mobility, armor, firepower, crew requirements, and ease of manufacturing.

Īutumn-class cruisers in Earth's low orbit 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. 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. 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. 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. 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.
