The Indian Air Force (IAF) has revealed the first image of its S-400 air defence system, named 'Sudarshan,' marking a significant enhancement to India's air defence capabilities. This advanced surface-to-air missile system is designed to detect and neutralize a wide range of aerial threats, including jets, UAVs, and missiles, over long distances. Its induction is seen as a paradigm shift, strengthening the nation's airspace protection and deterrence posture.
