In a significant leap toward bolstering India’s national security architecture, the Defence Research and Development Organisation (DRDO) is working on an ambitious and top-secret missile defense program—Project Kusha. Although largely kept under wraps, limited disclosures and strategic signals reveal that Project Kusha could become a critical layer in India’s multi-tiered Ballistic Missile Defence (BMD) system. As India’s strategic threats evolve, so does its approach to deterrence, and Project Kusha is a testament to that evolution.

What Is Project Kusha?

Project Kusha is a classified DRDO initiative designed to develop a next-generation ballistic missile interception system, likely capable of neutralizing intermediate-range and intercontinental ballistic missile (IRBM and ICBM) threats. Named after Kusha, the legendary son of Lord Rama, the project is a spiritual successor to earlier BMD phases but with significant technological advancements aimed at hypersonic and exo-atmospheric threats.

According to reports from India’s Ministry of Defence, the project was quietly sanctioned in 2022, with an allocation of over ₹4,500 crore (~$550 million USD), marking one of India’s most substantial investments in indigenous missile defense in recent years.

Strategic Context: Why Project Kusha Now?

India already possesses a robust missile defense roadmap. The earlier BMD phases focused on intercepting threats at endo-atmospheric (within the atmosphere) and exo-atmospheric (outside the atmosphere) levels using systems like PAD (Prithvi Air Defense) and AAD (Advanced Air Defense) interceptors.

However, with increasing missile sophistication from regional adversaries—especially China’s DF-26 and DF-21D missiles, and Pakistan’s Babur and Shaheen series—there is a clear need for a faster, higher-altitude, longer-range, and multi-target-capable system.

Project Kusha appears to be India’s response to:

• China’s expanding hypersonic and ICBM arsenal
• Pakistan’s continued development of tactical and cruise missile systems
• The global threat of MIRVs (Multiple Independently Targetable Reentry Vehicles)
• Space-based or near-space kinetic threats

Key Features (Expected) of Project Kusha

While much of Project Kusha remains classified, various defense sources and open-source intelligence point toward these capabilities:

🔹 Interceptor Missiles

• Likely to include exo-atmospheric kinetic kill vehicles (similar to THAAD or SM-3)
• Capable of neutralizing ballistic missiles in mid-course and terminal phase
• May include solid-fuel two-stage interceptors for rapid response

🔹 High-Speed Tracking Radars

• Likely to be integrated with Swordfish Long-Range Tracking Radar or its advanced variants
• Radar range: 1,500+ km, enabling early warning and tracking of incoming projectiles

🔹 Integrated Command and Control (C2) System

• Real-time data integration from satellites, radar systems, AWACS, and UAVs
• AI-enabled decision support for intercept coordination
• Seamless compatibility with Indian Air Defence Command under theatre commands

🔹 Kill Vehicle Technology

• Possibly based on hit-to-kill (HTK) principles using kinetic energy rather than explosive warheads
• Enhanced with infrared and radar seekers for terminal accuracy

Project Kusha vs. Other Global Systems

Interception Layer	Exo-atmospheric	High altitude & near-space	Exo-atmospheric	Low altitude (terminal)
Kill Method	Kinetic kill	Hit-to-kill + fragmentation	Kinetic kill	Fragmentation
MIRV/Hypersonic Capable?	Possibly Yes	Yes	Yes	No

Relation to Other Indian Defense Initiatives

Project Kusha is likely interconnected with other DRDO and military programs:

• Project AD-1 and AD-2 Missiles: Both are advanced long-range interceptors being tested for exo-atmospheric engagements.
• BMD Phase-II: Kusha may form the core of the second phase, targeting ICBMs and high-speed maneuvering warheads.
• NETRA and Space Surveillance: India’s space monitoring systems could provide early detection input for Kusha’s interceptors.

Testing & Timeline

• As per open-source defense monitoring, multiple AD-1 and AD-2 interceptor trials conducted at Wheeler Island (APJ Abdul Kalam Island) are seen as part of the Project Kusha framework.
• DRDO is aiming for limited operational capability by 2026–2027, with full-scale induction in the following years.
• User trials by the Indian Air Force and Strategic Forces Command are expected to follow once technical validation is complete.

Strategic Impact of Project Kusha

✅ Enhanced Strategic Deterrence

Project Kusha significantly boosts India’s capability to intercept nuclear-capable long-range missiles, deterring adversaries from considering first-strike options.

✅ Multilayered Missile Defense

Kusha complements:

• S-400 (already in service)
• Upcoming S-500 (if deal with Russia progresses)
• Indigenous PAD, AAD, and QRSAM systems

✅ Defending Urban & Strategic Assets

With higher accuracy and long-range interception, Kusha can protect critical infrastructure, nuclear command centers, space installations, and urban population centers.

Challenges Ahead

• Cost and Complexity: Advanced BMD systems are resource-intensive and require seamless coordination between multiple agencies.
• Technological Barriers: Hypersonic targets and MIRV technology are difficult to intercept reliably.
• Evolving Threat Landscape: Both China and Pakistan may seek countermeasures like decoys, EW jamming, and advanced cruise missiles.
• Secrecy vs. Transparency: While strategic secrecy is crucial, the public and parliamentary oversight is necessary for budgetary accountability.

Conclusion

Project Kusha is India’s bold answer to the evolving missile threats in Asia and beyond. It not only reflects a mature indigenous defense R&D ecosystem but also underscores India’s resolve to maintain strategic autonomy in a turbulent geopolitical environment. As Kusha advances from lab tests to field trials and full deployment, it could become one of the most significant milestones in India’s national security journey.
