Autumn-class heavy cruiser

The Autumn-class heavy cruiser is a class of capital ship commissioned into service with the UNSC Navy following the end of the Human-Covenant War. It was designed to be the successor for the Marathon class and the Halcyon class as most vessels of those classes were destroyed in the war. Many of these ships serve as escort vessels for the UNSC Infinity.

The Autumn class' name is a colloquialism for that of its lead ship, which in turn is named for the Halcyon-class UNSC Pillar of Autumn.

Specifications

Hull

Superficially, the Autumn class closely resembles the preceding Halcyon class, particularly the Pillar of Autumn after the ship's last refit in 2552. However, the Autumn class differs from its namesake in a number of details, primarily its much greater size. Specifically, an Autumn-class cruiser is 1,425 meters (4,674 ft) long (255 meters longer than a Halcyon) as well as proportionally wider and taller. It has a different number of viewports and the radar dishes are smaller, with different configurations across the hull. The antenna-like protrusion at the front of the ship is double the length of the original Pillar of Autumn's.

These vessels are equipped with energy shields.

Armament

The vessel's primary armament is a single Mark IX, Heavy Coil-45J3d3 Magnetic Accelerator Cannon. Secondary and tertiary armament comprises an unknown number of M58 Archer and Shiva-class nuclear missiles. The class sports thirty-six M910 point defense guns, four fewer than the Pillar of Autumn's complement.
