India Receives 4th S-400 Squadron, Major Boost To Air Defence Near Western Border

India's air defence capabilities have received a major boost with the arrival of the fourth squadron of the Russian-made S-400 Sudarshan Chakra missile system. Defence sources say the unit is expected to be deployed in Rajasthan, strengthening India's defensive posture along the western frontier. The delivery marks another milestone in the landmark India-Russia defence agreement, with the final squadron expected by late 2026. The S-400 gained significant attention during Operation Sindoor, where it reportedly played a crucial role in countering aerial threats. Capable of tracking and engaging multiple targets at long ranges, the system forms a key pillar of India's multi-layered air defence network.
