S-400 Missile
About
- The S-400 Triumf, developed by Russia’s Almaz Central Design Bureau, is widely regarded as one of the most advanced surface-to-air missile (SAM) systems in the world.
- The S-400 is designed to provide a multi-layered air defence shield capable of intercepting a broad spectrum of aerial threats, including fighter jets, ballistic and cruise missiles, drones and stealth aircraft within the range of 400km.
- Equipped with sophisticated phased-array radar, these missiles can engage multiple targets simultaneously flying at speeds up to Mach 14 (approximately 17,000 km/h) and at altitudes ranging from 10 metres to 30 kilometres.
Why in News?
- India has received the fourth squadron of the S-400 air defence system, strengthening the country’s long-range air defence network.
- The delivery is part of a $5.43 billion agreement signed between India and Russia in 2018 for the acquisition of five S-400 regimental systems. Three S-400 squadrons have already been inducted into service; the fourth has now arrived, following delays linked to the Russia-Ukraine conflict.
