Russia’s S-400 Triumf (NATO reporting name: SA-21 Growler) is an advanced long- and medium-range air defense and missile defense system that can use five different missile types to destroy aerial targets including planes, drones, cruise missiles and ballistic missiles at a range of 40 to 400 km (25 to 250 miles) at altitudes of up to 30 km.

The system was developed in the 1990s as an upgrade of the S-300 family, and was approved for service in Russia in 2007.

A typical S-400 system includes a combat control post, a jam-resistant phased array radar to detect aerial targets, and six to eight missile complexes.

The S-400 can detect targets up to 600 km away, and can engage up to 36 targets and guide up to 72 missiles simultaneously.
