Photo on the cover: S-400 Triumf Air Defence System
The S-400 Triumf is a new generation Russian air defence system developed by Almaz Central Design Bureau as an upgrade of the S-300 family. It is currently in limited service with the Russian Armed Forces.
The S-400's NATO reporting name is SA-21 Growler, and the system was previously known as S-300PMU-3. It overshadows the capabilities of the other systems from the S-300 series, and its range is said to be at least twice that of the MIM-104 Patriot system.
