The Iranian authorities announced the commissioning of a new underground base Oghab 44 of the Iranian Air Force. The air base, located underground, can accommodate various types of military aircraft, the video shows one of 70 American-made F-4 Phantom fighters of the Iranian Air Force. The air base is divided into several sectors: a command post, a combat alert zone, aircraft hangars, a repair and technical center, fuel storage facilities, rooms with navigation and airfield equipment. The reason why the base is built underground is the high probability of Israeli strikes against important Iranian ground targets. The Oghab 44 air base is not the first facility of its kind in Iran, earlier the Iranian Air Force disclosed information about the underground UAV base, called Drone Base 313.
