S-400 Air Defence Systems- Gamechanger in a True Sense: All you need to know


S-400 Air Defence Systems: The S-400 Triumf, previously known as the S-300 PMU-3, is an anti-aircraft weapon system developed in the 1990s by Russia's Almaz Central Design Bureau as an upgrade of the S-300 family. It has been in service with the Russian Armed Forces since 2007. 

The S-400 uses four missiles to fill its performance envelope: the very-long-range 40N6 (400 km), the long-range 48N6 (250 km), the medium-range 9M96E2 (120 km) and the short-range 9M96E (40 km). The S-400 was described by The Economist in 2017 as "one of the best air-defence systems currently made".

Despite the threats of sanctions looming large, India went ahead with the S-400 deal with Russia and inked the pact to procure the air defence systems during Vladimir Putin's visit to New Delhi in October. The S-400 Triumph missile defense system is a significant strategic upgrade in India's military hardware.
