Ru'swum-pattern Phantom

Were you looking for the Type-52 Phantom, which was introduced in Halo 2?

The Type-44 Troop Carrier, commonly known as the Phantom, is a Covenant dropship manufactured by Achoem Weapons.

Overview
The Type-44 Phantom's prominence was due to its speed, maneuverability, and firepower in atmospheric and exoatmospheric environments. It was later supplanted by a newer model, the Type-52, which was ubiquitous later in the Human-Covenant War. Jul 'Mdama's Covenant faction uses the Type-44 as their primary dropship, likely due to the scarcity of the newer model.

Trivia

 * The Type-44 shares the same aesthetic properties as the Type-52 from Halo: Reach.
 * During the level Composer, in the hangar, if the player activates the barrier while a Phantom is still inside the station, the vehicle will explode once it comes in contact with the barrier.
