The new S-400 Triumph air defence system has been deployed for combat duty in the Moscow region, according to the Russian Defence Ministry.
Speaking to Russian news agency Interfax, the Defence Ministry’s Department of Information and Mass Communication said: “The SAM combat squads of the Moscow Region aerospace forces have put the new S-400 Triumph air defence missile system into service, and have gone on combat duty for the air defence 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 defence and protecting vital state, military, industry and energy facilities, as well as the Armed Forces troops and transport communications, from aerospace attacks.”
The new missile system, known as SAM, had been trialled in Kapustin Yar in southern Russia, and following successful testing it was transported to the Moscow region last month.
A total of four S-400 systems are due to enter service in 2017 after four air defence regiments were re-equipped with the new S-400 system last year.
The advanced anti-aircraft systems have been providing defence for Russian forces based in Syria since November, after Russian president Vladimir Putin ordered their deployment.
After their deployment was announced, Russian Defence Minister Sergey Shoigu said the S-400 system allows Russia to “destroy both sea and ground targets”.
The measures are aimed at reassuring US allies in the region following Russia’s annexation of Crimea in 2014.
US and Polish forces are expected to participate in a large ‘massing’ exercise in Poland at the end of the month.
