Synopsis
- The concept envisions a five-layer integrated air and missile defence architecture, combining directed-energy weapons, short-range interceptors, long-range air defence systems, and advanced ballistic missile defence.
Mission Sudarshan Chakra represents India’s emerging roadmap to counter the growing missile and drone threat posed by the People’s Liberation Army Rocket Force. The concept envisions a five-layer integrated air and missile defence architecture, combining directed-energy weapons, short-range interceptors, long-range air defence systems, and advanced ballistic missile defence. The goal is to neutralize potential missile saturation attacks and grey-zone drone warfare along the Himalayan frontier.
Understanding the PLARF Threat
Over the past decade, China has expanded the capabilities of the People’s Liberation Army Rocket Force (PLARF), deploying a wide range of ballistic and cruise missiles capable of striking targets across Asia.
Modern Chinese missile doctrine increasingly emphasizes saturation attacks, where dozens of missiles could be launched simultaneously to overwhelm enemy air defence systems. Some estimates suggest that a large-scale strike scenario could involve 50 or more missiles fired in coordinated waves, supported by drones and electronic warfare systems.
Among the systems raising concern for regional planners are hypersonic weapons such as the DF-17, which combine maneuverability with extremely high speeds, making them difficult to intercept with conventional missile defence systems.
Mission Sudarshan Chakra aims to address these challenges through a layered defensive network, allowing India to engage incoming threats at multiple ranges and altitudes.
Tier 1: Terminal & Counter-Swarm Layer (Drone Shield)
The first defensive layer focuses on neutralizing low-cost drone swarms and loitering munitions, which have become increasingly common in modern conflicts.
Key systems in this tier include:
- Bhargavastra – an indigenous counter-drone system designed to destroy hostile UAV swarms.
- Redon Bheeshan – a short-range anti-drone weapon system intended for base protection.
- DRDO Durga-II DEW – a directed-energy weapon under development capable of using high-energy lasers to disable drones and electronic sensors.
The advantage of directed-energy systems such as Durga-II lies in their very low cost per shot, making them ideal for countering large drone swarms that might otherwise exhaust missile-based defenses.
Tier 2: Short to Medium Range Defence (Point Protection)
The second layer is designed to protect forward bases, logistics hubs, and military formations near the Line of Actual Control.
Important systems include:
- QR-SAM – mobile missile defence for fast-moving battlefield scenarios.
- VSHORADS – shoulder-fired systems for engaging low-flying aircraft and drones.
- Akash-1S – radar-guided missile system designed for short to medium range air defence.
Together, these systems provide point defence coverage against cruise missiles, attack helicopters, and tactical UAVs operating close to the frontline. Recent operational success of the Akash short-range air defence system against Pakistani rockets, missiles, and aircraft made it battle-tested for the very first time. Its upgraded version, Akash-NG, is now almost on the verge of operational induction and deployment, which is superior in range, detection, and interception capability.
Tier 3: Long-Range & Theatre Air Defence
The third layer aims to create a deep defensive shield across large geographic areas, capable of targeting high-value enemy aircraft.
Key components include:
- S-400 Triumf – capable of intercepting aircraft and missiles at ranges up to 400 kilometres.
- Barak-8 – deployed for both naval and land-based air defence with ranges upto 100 kilometres.
- Project Kusha – India’s upcoming long-range surface-to-air missile system currently under development. It will be similar in range and detection capability like the Russian S-400 Triumf system with a range of 400 kilometres. It will be able to intercept aircraft, hypersonic missiles, ballistic missiles, cruise missiles.
These systems are designed to deny airspace to hostile fighter aircraft and other high-value targets like airborne early warning aircraft, refuelling tankers, long-range bombers, short-range ballistic missiles, hypersonic missiles, and cruise missiles operating from bases deep inside Tibet.
Tier 4: Strategic Umbrella – Ballistic Missile Defence
Beyond traditional air defence lies India’s Ballistic Missile Defence (BMD) architecture, designed to intercept incoming ballistic missiles in both exo-atmospheric and endo-atmospheric phases.
This program, led by the Defence Research and Development Organisation (DRDO), has already demonstrated successful interceptor tests. The next stage involves deploying advanced interceptors capable of dealing with higher-speed threats.
Future interceptors such as the AD-1 interceptor missile and the AD-2 interceptor missile are expected to strengthen this strategic shield.
Sensor Fusion: The Brain Behind the Shield
A layered defence system only works if all components are connected through a common command network. In India’s case, this role is performed by the Integrated Air Command and Control System.
The system integrates radar inputs, satellite surveillance, and battlefield sensors into a unified command network. Through this architecture, a frontline missile operator using a short-range defence system can receive targeting data from long-range surveillance radars or airborne sensors.
This sensor fusion approach allows India to respond more effectively to complex threats such as simultaneous drone and missile attacks.
The Road Ahead: Preparing for Hypersonic Warfare
While existing layers already provide significant defensive coverage, future challenges are expected to come from hypersonic glide vehicles and advanced maneuvering missiles.
India’s next phase under Ballistic Missile Defence, named BMD Phase-III will feature AD-AH (Air Defence – Anti Hypersonic) and AD-AM (Air Defence – Anti Missile) interceptors that will provide defence against Hypersonic Glide Vehicles and Hypersonic Cruise Missiles respectively. These systems are currently in design and development phase. This phase of the BMD, is very cruicial in terms of India’s air defence network in the long run as China is investing heavily on hypersonic systems which is a threat for any existing air defence systems around the world.
Mission Sudarshan Chakra, therefore, represents more than a single system—it is an evolving architecture designed to protect India’s airspace against a rapidly changing missile and drone threat environment. Particularly assessing the Chinese Rocket Force, its future upgrades, and continuous stress on hypersonic systems development has made Indian Defence Planners create an umbrella of protection which will not only protect India’s capital but the entire country if a situation of saturation attack by missiles, drones, and aircraft happens in the future, especially in any intense war against China.
