Autumn-class cruiser

The Autumn-class (C98H) of heavy cruisers is the UNSC Navy's first class of cruisers designed for the post-war environment. Autumn and her sister ships are manufactured by to specifications of the retrofitted -class light cruiser, of which the lead ship is named after.

Slated to replace the aging -class beginning in 2555 on a 3:1 basis to bolster the Navy's cruiser strength, these multi-role warships wield their power to conduct fleet command-and-control, anti-air defense, and independent long-range scouting. Highly mobile Carrier Strike Groups place Autumn-class cruisers as the nucleus of their escort force. The colonial flagship, Infinity (ASVK-1), is rarely seen without a complement of a half dozen or more of these ships.

These cruisers introduced the layered defense scheme in the Navy, with new ships equipped with advanced Titanium battle plating (armored) and/or energy shielding (protected); the Autumn-class is hardened with a dual armored-protected system.
