What is it?
- It is an air defence missile system developed by Russia, which integrates a multifunction radar, autonomous detection and targeting systems, anti-aircraft missile systems, launchers, and command and control centre.
- It is essentially one of the best Modern Long-Range Surface to Air Missile (MLR SAM) in the world, considered much ahead of the US-developed Terminal High Altitude Area Defense system (THAAD).
- It is capable of firing three types of missiles to create a layered defence.
- Within a range of 400 kilometres and at a height of up to 30 kilometres, the system can engage all types of aerial targets, including aircraft, unmanned aerial vehicles (UAVs), and ballistic and cruise missiles.
- It can track 100 airborne targets and engage six of those airborne targets at the same time, and it can be integrated into existing and future air defence units of the air force, army, and navy.
- The command post is equipped with LCD consoles to process the air space surveillance data of the individual batteries.
- It controls and monitors long-range surveillance radar, tracks airborne threats, prioritises the threats, and coordinates other batteries.
Significance of acquiring S-400 Triumf
- India’s acquisition is crucial to counter attacks in a two-front war.
- For the Indian Air Force (IAF), the high-end technology S-400 would give a fillip and make up for its falling fighter aircraft squadrons in the medium-term.
- China has also agreed to purchase six battalions of the S-400 Triumf from Russia, thus India should be ready to confront it.
- The S-400 system’s acquisition by China has been dubbed a “game changer” in the region. Its usefulness against India, however, is limited. Experts say Delhi would be at the end of its range even if stationed right on the India-China border and relocated into the Himalaya mountains.
Why in News
