Covenant air artillery

ERA HUMAN-COVENANT WAR Air Artillery

The Covenant Air Artillery was an early airborne Covenant weapons platform armed with three Plasma Mortars (also the main armament of the Wraith). As it had no onboard defenses, it could have been very vulnerable if dealt with promptly. However, its heavy plasma mortar cannons could lay waste to an entire UNSC base. This unit was cut from the final game.

Trivia

 * It was replaced in the game by the new Vampire due to the fact that the Covenant already have many vehicles. It was also the first known unit to be deleted from Halo Wars.
 * it is most likely like 3 wraiths put together
