UNCOVERED /  VIDEO – The Iranian air force and air defense base in Mehrabad-Tehran protects airspace out to roughly 300 kilometers (186 miles) around Tehran, an area with many security assets. Pay attention to the types of fighter and transport aircraft in the base and the array of radars and air defense batteries. The Iranians placed their most advanced systems: Iranian-made radars and fire control belonging to the Bavar 373 air defense system (with high probability also deployed in Syria) and Russian S-300 batteries.
