The Syrian Air Defense Force (SyADF), officially the Syrian Arab Air Defense Force (Arabic: قوات الدفاع الجوي العربي السوري) is an independent command within the Syrian Armed Forces. It is responsible for protecting the Syrian airspace against any hostile air attacks. The SyADF is one of the most powerful and combat-tested air defence forces in the region. A large number of Iranian air defense systems were delivered to the country in 2021: Mersad, Khordad-3, Bavar-373 and Khordad-15 systems.
