The Autumn class' name is a colloquialism for that of its lead ship, which in turn is named for the Halcyon-class. Many of these ships serve as escort vessels for the.

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 4674 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.

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.
