TEHRAN (FNA)- The Russian military has delivered new units of its state-of-the-art S-400 anti-aircraft systems to Syria.
Videos provided by the country's Defense Ministry show the arrival of four of the systems, RT reported.
Two were delivered by air to the Humeimim Airbase in the Syrian province of Lattakia, and two more were shipped to a Russian maritime facility located in Tartus.
The S-400 is the latest generation of Russian mobile anti-aircraft systems currently in service. It is designed to engage aerodynamic targets and ballistic missiles.
An S-400 unit can engage up to 36 targets simultaneously, according to its manufacturers, Almaz Antey.
In 2015, Russia deployed the system to Humeimim to ensure the safety of its aircraft during their operations against ISIL in Syria. The deployment came after the downing of a Russian Su-24 bomber by Turkey.
