TEHRAN (Press Shia Agency) – A video footage released by the Russian Defense Ministry showing the delivery of S-300 systems, interceptor missiles, radars and other hardware to Syria.

The delivery of Russian air-defense system to Syria is meant to boost the country’s air-defense capabilities in the wake of the downing of the Russian Il-20 military plane.

The night-time footage shows the military hardware being unloaded off the world's largest military transport jet, the Antonov An-124 Ruslan (the Condor), designed to carry a payload of 120 tons.

The video shows the gigantic front cargo doors of the aircraft opening up, through which the Russian servicemen rapidly unload an S-300 launcher, radar and control vehicles, as well as the mounting of surface-to-air interceptor missile tubes onto a hauling unit.2

According to Defense Minister Sergey Shoigu a total of 49 pieces of military equipment were supplied to Damascus and all of it will be integrated with the Russian anti-air capabilities into a unified air defense control system by October 20, while Syrian crews will be trained to operate the new hardware within three months.

The delivery of S-300 units to Damascus was ordered by President Putin in response to the downing of the Il-20 reconnaissance plane with 15 servicemen on board by Syrian air-defense units during an Israeli raid.
