In this segment of OPEN COLLAR, Major Gaurav Arya and Air Vice Marshal P.K. Srivastava (Retd.) explain India’s Integrated Air Command and Control System (IACCS) — the invisible network behind the country’s air defence. They discuss how radars, satellites, and sensors from the Army, Navy, and Air Force combine to create a real-time national air picture, enabling rapid detection, identification, and interception of aerial threats like missiles, aircraft, and drones.
