India has taken a major step towards becoming self-reliant in strategic defence technologies with the successful maiden flight test of the Project Kusha Long-Range Surface-to-Air Missile (LRSAM). Developed by the Defence Research and Development Organisation (DRDO), Project Kusha is expected to become the backbone of India’s future air defence network and significantly reduce dependence on imported systems such as Russia’s S-400 Triumf.
The successful test marks the beginning of a new era in India’s indigenous missile development programme, strengthening the country’s capability to defend against modern aerial threats including fighter aircraft, cruise missiles, drones and high-speed airborne targets.
What is Project Kusha?
Project Kusha is India’s ambitious Extended Range Air Defence System (ERADS) designed to provide layered protection against multiple airborne threats over long distances.
The system is being developed entirely in India by DRDO with support from Indian defence industries. It aims to provide a highly mobile and network-centric air defence solution capable of protecting:
- Major cities
- Strategic military bases
- Air Force stations
- Naval installations
- Critical infrastructure
- Industrial hubs
Unlike conventional missile systems that defend only limited areas, Project Kusha is designed to become an integrated part of India’s nationwide air defence architecture.
Successful Maiden Flight Test
On 23 July 2026, DRDO successfully conducted the maiden flight test of the Kusha Long-Range Surface-to-Air Missile from APJ Abdul Kalam Island off the Odisha coast.
According to the Ministry of Defence:
- The missile intercepted a simulated high-speed, high-altitude aerial target.
- The engagement validated the missile’s guidance, navigation and control systems.
- All critical subsystems functioned as planned.
- The test demonstrated India’s capability to build indigenous long-range air defence systems.
Raksha Mantri Rajnath Singh described the achievement as a major milestone that will eventually eliminate India’s dependence on imported long-range air defence systems.
Key Features of Project Kusha
Project Kusha incorporates several advanced technologies:
- Long-range interception capability
- Multi-target engagement
- Network-centric operations
- Indigenous AESA radar integration
- Mobile launch vehicles
- Advanced command and control systems
- High survivability in electronic warfare environments
- Ability to intercept multiple aerial threats simultaneously
The system has been designed for rapid deployment and integration with India’s Integrated Air Command and Control System (IACCS).
Three Interceptor Variants
Project Kusha is expected to operate with three different interceptor missiles, creating a layered defence shield.
| Variant | Approximate Range | Primary Role |
| M1 | Around 150 km | Aircraft, UAVs, Cruise Missiles |
| M2 | Around 250 km | Extended Air Defence |
| M3 | Up to 350–400 km | Long-range interception of advanced aerial threats |
This layered approach allows India to engage hostile aircraft and missiles at different distances before they approach strategic targets.
What Threats Can Project Kusha Destroy?
Project Kusha is designed to intercept:
- Fighter aircraft
- Cruise missiles
- Armed drones
- UAVs
- AWACS aircraft
- Electronic warfare aircraft
- Large surveillance aircraft
- Stand-off precision weapons
According to DRDO, the system is capable of handling a wide variety of aerial threats across a large range and altitude envelope.
Is Project Kusha India’s S-400?
Project Kusha is frequently compared with Russia’s S-400 because both are long-range air defence systems.
However, there are important differences.
Similarities
- Long-range engagement capability
- Layered defence
- Mobile launchers
- Multi-target interception
- Networked radar systems
Differences
The Russian S-400 can intercept certain ballistic missiles in addition to aircraft and cruise missiles.
Current information indicates that Project Kusha is primarily designed to counter aircraft, drones and cruise missiles rather than ballistic missile threats. India’s dedicated Ballistic Missile Defence (BMD) programme addresses that requirement separately.
Why Project Kusha is Strategically Important
India currently operates Russian-origin S-400 air defence systems. While these systems have significantly strengthened India’s defensive capability, dependence on imports creates long-term challenges including:
- Foreign supply chains
- Spare parts availability
- Upgrade dependency
- Geopolitical uncertainties
- High acquisition costs
Project Kusha aims to overcome these challenges by providing a fully indigenous alternative developed and manufactured in India.
Benefits for India’s Defence Ecosystem
Project Kusha supports several national objectives:
Boost to Atmanirbhar Bharat
The project encourages domestic manufacturing and indigenous defence technologies.
Lower Import Dependency
Future procurement can increasingly rely on Indian industry rather than foreign suppliers.
Faster Upgrades
Since the technology remains under Indian control, future upgrades can be implemented without depending on overseas manufacturers.
Export Potential
If successfully inducted, Project Kusha could emerge as a competitive export product for friendly countries looking for advanced air defence systems.
Role in India’s Multi-Layer Air Defence Network
Project Kusha will complement existing systems including:
- Akash
- MR-SAM
- QRSAM
- S-400
- Ballistic Missile Defence Programme
Together, these systems are expected to create a comprehensive multi-layered air defence umbrella capable of defending India against evolving aerial threats.
Future Roadmap
Following the successful maiden flight test, DRDO is expected to conduct additional developmental and user trials before induction into the Armed Forces.
Further testing will validate:
- Extended engagement ranges
- Different interceptor variants
- Simultaneous target engagement
- Operational deployment scenarios
- Integration with existing air defence networks
The project is expected to become a cornerstone of India’s future air defence architecture over the coming years.
Conclusion
Project Kusha represents one of India’s most significant indigenous defence programmes in recent years. By developing a long-range, network-centric air defence system domestically, India is moving closer to strategic self-reliance while reducing dependence on imported platforms.
The successful maiden flight test has demonstrated DRDO’s growing technological capability and marked an important milestone in strengthening India’s national security. As additional trials are completed and the system moves towards induction, Project Kusha is expected to become a vital component of India’s integrated air defence network and a symbol of the country’s expanding defence manufacturing capabilities.
