In a move that some say is directly related to the Obama administration sending 3000 US troops to Poland, Russia is installing advanced anti-aircraft missiles around their capital city of Moscow.

The S-400 Anti-Aircraft Missile System (NATO codename SA-21 Growler) was originally developed in the 1990’s and has been in service since 2007. The S-400 uses a four missile package with each missile designed for different ranges: very-long-range (400 km), long-range (250 km), medium-range (120 km) and short-range (40 km).

Defense Ministry’s Department of Information and Mass Communication told Interfax: ‘The SAM combat squads of the Moscow Region aerospace forces have put the new S-400 Triumph air defense missile system into service, and have gone on combat duty for the air defense of Moscow and the central industrial region of Russia.

‘The main task of the anti-aircraft missile troops of the Russian Aerospace Forces is air defense and protecting vital state, military, industry and energy facilities, as well as the Armed Forces troops and transport communications, from aerospace attacks.’ – Daily Mail

The S-400 is one of Russia’s most technologically advanced anti-air defense systems.
