The S-400 is Russia's most advanced anti-aircraft defense system. It is as an upgrade of the S-300 Growler family, designed and developed by Almaz Antei. The S-400 is employed to ensure air defense using long- and medium-range missiles that can hit aerial targets at ranges up to 400 kilometers. The S-400 is capable of hitting tactical and strategic aircraft as well as ballistic and cruise missiles. The system includes a set of radars, missile launchers and command posts, and is operated solely by the Russian military. Khmeimim airbase in Latakia, Syria, accommodates Russian Air Force squadrons of Su-27SM and Su-30 fighter jets, Su-34 and Su-24 tactical bombers, which are all taking part in airstrikes on Islamic State positions. The airbase is protected by state-of-the-art air defense systems and radars. Khmeimim also has a fully operational unit for maintaining fixed- and rotor-wing aircraft and providing logistical assistance to pilots.
