In service since 2007, the S-400 Triumf (NATO codename SA-21 Growler) is an anti-aircraft and anti-missile system capable of intercepting all types of modern air weaponry, including fifth-generation warplanes, as well as ballistic and cruise missiles at a maximum range of nearly 250 miles. The complex, comprising up to eight battalions, is reported to be capable of engaging up to 80 targets.
The S-400 is equipped with four types of missiles, including the very-long-range 40N6, which is said to have an operational range of 400 km (nearly 250 miles), the long-range 48N6 missiles (250 km), the medium-range 9M96E2 missiles (120 km) and the short-range 9M96E (40 km).
