Unidentified UNSC capital ship (dorsal plated)

This class of ship was attached to Battlegroup Dakota of the UNSC Navy.

Design
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 and attacked the Mantle's Approach during the Didact's attack on Earth in 2557.

Behind the scenes
These ships are intended to appear only in the background during the level Midnight. However, exploiting a glitch allows the player to examine these vessels up close, along with two other theretofore-unseen classes. 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.
