The Russian S-400 SAM, known as the “Triumf” at home and better known to NATO as the SA-21 “Growler,” is the most capable and lethal long-range air defense missile system on the planet.
Developed by Almaz-Antey Central Design Bureau, the SA-21 has been in service with the Russian military since 2007. The system is capable of destroying airborne targets as far as 250 miles away
