S-400 ‘Growler’ missile systems – used widely in Syria – have been stationed outside the Russian capital.
Russia’s defense ministry also confirmed that an air force regiment had been deployed to the region around the city.
Another air defense regiment equipped with the S-400 system will be put on combat duty near Moscow soon, officials said.
The S-400, known in Russia as the ‘Triumf’ missile system and by NATO as the ‘Growler’, is the country’s most advanced surface-to-air missile system and can hit a target 250 miles away.
The weapon has been sent to the city of Podolsk, 15 miles south of Moscow, local media reported.
“The combat crews of the Aerospace Forces’ Moscow Region air defense formation’s surface-to-air missile regiment, which received the new regimental set of the S-400 anti-aircraft missile system, have begun air defense combat duty on Wednesday, January 11, in Moscow and Russia’s central industrial region,” the defence ministry said.
The deployment will offer protection to the Russian capital at a time of heightened tensions with the West.
