Five air defense regiments will be rearmed with advanced S-400 Triumf air defense systems in 2016, Chief of the General Staff of the Russian Armed Forces Gen. Valery Gerasimov said Friday.
"This year, five air defense regiments will be rearmed with S-400 air defense systems," Gerasimov said in an interview with Rossiya-24 television.
S-400 Triumf (NATO reporting name SA-21 Growler) is by far Russia's most advanced surface-to-air missile system that has a range of 400 kilometers (248 miles) and is capable of tracking and destroying all existing aerial targets, including ballistic and cruise missiles.
