Context
India has embarked on the ambitious “Sudarshan Chakra” shield project—a fully integrated, multi-layered air and space defence system designed to protect vital national assets and population centres by 2030. Combining satellite surveillance, advanced radars, directed energy weapons (DEWs), and missile systems, this initiative marks a transformative step in India’s quest for comprehensive aerospace security and technological sovereignty.
Key Highlights
- Strategic Objective:
Mission Sudarshan Chakra aims to create a national defensive umbrella against aerial threats ranging from missiles and aircraft to drones and hypersonic systems. - Space-Based Surveillance:
The shield will incorporate 52 new surveillance satellites under the Space-Based Surveillance (SBS) Programme to provide real-time tracking of airborne threats across India’s borders and oceanic regions. - Advanced Weapon Integration:
The system will include Over-the-Horizon (OTH) radars, Directed Energy Weapons (DEWs), and integrated missile batteries capable of intercepting high-speed projectiles. - Core System – IADWS:
The Integrated Air Defence Weapon System (IADWS)—featuring multi-layered missile networks and a 5-kilowatt laser weapon—will serve as the operational backbone of the shield. - Indigenous Development:
The Defence Research and Development Organisation (DRDO) is leading the indigenous design and production, ensuring reduced import dependency and alignment with the Aatmanirbhar Bharat vision.
Significance
- Comprehensive Network Design:
The shield will integrate multiple systems—satellites, radars, anti-aircraft guns, anti-drone systems, and missiles—into a single real-time communication grid capable of automated threat detection and interception. - AI and Quantum Integration:
Artificial Intelligence (AI), machine learning algorithms, data analytics, and quantum computing will enhance situational awareness and accelerate decision-making in live combat environments. - Over-the-Horizon Radars:
These radars can detect targets beyond the line of sight by reflecting signals off the ionosphere, offering early warning of incoming aircraft or missiles hundreds of kilometres away. - Directed Energy Weapons (DEWs):
Laser-based DEWs will form the inner defensive layer, neutralizing low-altitude drones, UAVs, and precision-guided munitions with pinpoint accuracy and minimal collateral damage. - Strategic Coverage:
The system will prioritize metropolitan cities, critical infrastructure, nuclear facilities, and major defence installations, eventually expanding into a nationwide command-and-control network.
Technological and Strategic Implications
- The project signifies a fusion of space and terrestrial defence, positioning India among nations like the U.S., Russia, and China that possess integrated aerospace command capabilities.
- The Sudarshan Chakra shield will enhance India’s ability to detect, deter, and destroy threats long before they breach national airspace.
- It underscores India’s transition from reactive air defence to proactive, predictive, and autonomous protection through indigenous innovation and advanced research.
