DRDO’s Project Kusha Phase II to Match S-500 Level Capabilities with Mach 7 Interceptor Missiles
India Defense
India is taking a major leap in indigenous defence technology with Project Kusha, an ambitious long-range air defence system developed by the Defence Research and Development Organisation (DRDO). Aimed at achieving capabilities on par with Russia’s advanced S-400 Triumf and potentially even the S-500 Prometheus, Project Kusha is a vital step in enhancing India’s strategic autonomy and self-reliance in defence production.
A New Era in Indian Air Defence
Project Kusha, also known as the Extended Range Air Defence System (ERADS) or Programme Long Range Surface-to-Air Missile (PGLRSAM), is designed to protect Indian airspace from a wide range of threats including stealth aircraft, ballistic missiles, and electronic warfare platforms. It fills the operational gap between India’s MR-SAM (Medium-Range Surface-to-Air Missile) with a range of 80 km and the S-400 system, which can strike targets up to 400 km away.Three Powerful Interceptor Missiles
At the heart of Kusha’s firepower are three types of interceptor missiles:- M1: Range up to 150 km
- M2: Range up to 250 km
- M3: Range up to 350 km
Advanced Specifications and Capabilities
- Kill Vehicle Diameter:
- M1 and M2: 250 mm
- M3: 450 mm
- Propulsion: All three missiles use dual-pulse solid rocket motors with thrust vector control, allowing high maneuverability during engagement.
- Hit Probability:
- Single missile: 85%
- Two missiles in salvo: 98.5%
- Radar and Sensors:
- Project Kusha will incorporate Swordfish Long Range Tracking Radar, upgraded to detect targets up to 1,500 km away.
- It will also feature AI-driven fire control systems for faster response and coordinated interception.
- Surveillance Range: The system’s radars can scan and track airspace 500–600 km deep into enemy territory, giving early warning against cruise missiles, stealth aircraft, drones, and hypersonic glide vehicles.
Phase-II and Beyond: Eye on S-500 Capabilities
The next stage of Project Kusha, referred to as Phase-II, aims to develop interceptors with ranges exceeding 400 km. These will target hypersonic weapons and next-generation ballistic threats, rivaling even the Russian S-500, which is designed to destroy hypersonic missiles and intercept targets at 600 km.
While technical details of Phase-II remain classified, its goals include:
- Defending against hypersonic glide vehicles (HGVs)
- Integration with space-based early warning systems
- Development of mobile launcher platforms for fast deployment
Leveraging Existing Missile Defence Experience
Project Kusha draws heavily from the technology base of India’s Ballistic Missile Defence (BMD) programme. Components and know-how from BMD systems are being reused to fast-track development. For instance, the M3 interceptor includes parts adapted from India’s Phase-I BMD missiles, enabling it to effectively neutralize high-value targets such as AWACS and electronic warfare aircraft.
This cross-utilization not only reduces cost but also shortens development timelines and enhances battlefield synergy across missile systems.
Operational Timeline and Cost-Effectiveness
- Deployment Goal: Full operational capability is expected by 2028–2029.
- Cost: Around ₹21,700 crore (~$2.6 billion) for five squadrons, making it significantly more affordable than importing five S-400 units, which cost approximately $5.25 billion.
Integration into India’s Air Defence Network
The Indian Air Force (IAF) will lead the integration of Project Kusha into the Integrated Air Command and Control System (IACCS). It will operate seamlessly alongside other air defence systems like:- Akash SAM
- Barak-8 (LR-SAM)
- S-400 Triumf
Strategic Shield for the Future
Project Kusha is more than a missile system—it’s a symbol of India’s defence transformation. With cutting-edge interceptors, AI-powered radar systems, and ambitions to counter hypersonic threats, Kusha will place India among the elite few nations capable of defending against next-generation aerial and missile warfare.By building a system comparable to the S-500, India not only enhances its strategic deterrence but also sends a clear message: the future of Indian defence is indigenous, advanced, and unstoppable.
