Poseidon-class light carrier
From Halopedia, the Halo wiki
The Poseidon-class carrier is sleek, elongated, and somewhat cylindrical in general shape. Its structure comprises two main sections covered with white plating; in the fore section, the plating mostly covers the vessel's dorsal surface. This plating is absent on most of the underside of the ship and in a spar connecting the two main sections. A series of rectangular blue lights are arranged in the sections lacking the white plating. 719 meters in length, the Poseidon is exceeded in both size and tonnage by the Orion, Epoch, and Punic carrier classes. It is armed with point defense guns and presumably at least one Magnetic Accelerator Cannon.
Several ships of this class were part of Battle Group Dakota alongside a number of Vindication-class light battleships and Strident-class heavy frigates. These ships engaged the Forerunner vessel Mantle's Approach during the Didact's attack on Earth on July 25, 2557.
