SA-21 Growler

The SA-21 Growler (Russian: S-400, also known as the Triumf) is an air and theater defense missile system based on the SA-10 (S-300PMU) family. It is designed to detect and destroy airborne targets at a range of up to 216 nm (249 mi, 400 km), or more than twice the range of the SA-10. Its target set includes low-signature and fast-moving threats such as missiles.

The Growler can track more targets and has improved electronic counter-countermeasures compared to earlier S-300...
