Poseidon-class light carrier

The Poseidon-class light carrier is a capital warship in service with the UNSC Navy in the post-Covenant War years.

Design details
This class of ship is sleek, elongated and somewhat cylindrical in general shape. It consists of two major 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.

Service history
Several ships of this class were part of Battlegroup Dakota alongside a number of s and s and attacked the Mantle's Approach during the Didact's attack on Earth in 2557.

Behind the scenes

 * Several Poseidon-class light carriers appear in the background of the Halo 4 level Midnight; given their nature they are intended to be seen only from a considerable distance. However, exploiting a glitch allows the player to examine these vessels up close, along with a number of s and s. Because these ships are intended to appear only as scenery, they are rendered as brushes rather than level geometry; as such, the player can fly the Broadsword through them without harm. By the same merit the ships' in-game models are not to scale with their canonical incarnations.
 * The Poseidon-class carrier and Vindication-class battleship were to be featured in Halo 4: The Essential Visual Guide but were cut due to space constraints.
