Deleted vehicles of the Covenant

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 on board 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.

The Gorgon was intended to be a Covenant anti-air oriented ground vehicle to appear in Halo Wars, likely filling a similar niche to the UNSC MAAT-9 Wolverine. It used two sturdy legs to carry a bulky chassis, which was equipped with several Heavy Needlers capable of shooting down enemy aircraft. It was eventually deleted in favor of the Vampire unit for two reasons: it created a recognition problem, confusing players as to whether it was infantry or a vehicle; and the Covenant had too many ground units already, and needed more air units.
