The Covenant Air Artillery was an early airborne Covenant vehicle armed with three Plasma Mortars (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. It only appears in Halo Wars.[1] Ensemble has confirmed that the unit has been cut[2] from the final game.
