The Defence Research and Development Organisation has successfully conducted the maiden flight-test of the indigenous Kusha Long-Range Surface-to-Air Missile. Fired from the APJ Abdul Kalam Island off the coast of Odisha, the missile engaged an electronic target simulating a high-speed, high-altitude aerial threat. The system successfully intercepted the target, validating the missile along with its associated radars, tracking systems, and command infrastructure.
This test marks a key milestone for Project Kusha, formally known as the Extended Range Air Defence System. Developed primarily for the Indian Air Force, the project aims to give India a homegrown long-range air defense umbrella comparable to top global systems.
Understanding Project Kusha and Its Core Specifications
Project Kusha is designed to protect critical infrastructure, military bases, and airspace from a wide range of airborne threats. These include fighter jets, stealth platforms, unmanned aerial vehicles, cruise missiles, and high-altitude targets.
Instead of relying on a single missile, the system uses a three-tier interceptor architecture. This design allows the system to engage targets at different distances and altitudes efficiently.
- Kusha M1 Interceptor: Designed for short to medium ranges up to 150 kilometers, this missile handles tactical targets like fighter aircraft, drones, and cruise missiles.
- Kusha M2 Interceptor: Extends the engagement zone out to 250 kilometers, providing mid-tier coverage against high-speed incoming threats.
- Kusha M3 Interceptor: The longest-range variant, built to hit targets between 350 and 400 kilometers away. This missile travels at speeds around Mach 5.5 and targets high-value enemy assets.
All three interceptor variants use dual-pulse rocket motors and active radar seekers to ensure high accuracy during terminal flight. Bharat Electronics Limited serves as the primary integration partner for the radar and electronic systems, while Bharat Dynamics Limited handles missile assembly.
Integration into India’s Integrated Air Defence Network
The true strength of the Kusha system lies in how it connects with existing air defense infrastructure. Rather than operating as an isolated battery, Kusha is fully integrated into the Indian Air Force’s Integrated Air Command and Control System.
This network-centric setup combines feeds from military radars, civilian radars, and satellite tracking stations across the country into a single air picture. This allows the command center to automatically evaluate incoming threats and assign the most suitable interceptor.
When integrated, Kusha bridges the gap between India’s medium-range missiles, such as the 80-kilometer MR-SAM, and imported long-range systems like the Russian-made S-400. By combining short, medium, and long-range systems under a unified command network, India creates a layered defense shield. If an enemy threat slips past long-range interceptors, medium and short-range systems like Akash and Quick Reaction SAMs stand ready to engage.
Practical Use Case Scenarios
The 400-kilometer reach of the Kusha M3 missile alters tactical planning in potential border conflicts.
- Neutralizing Support Aircraft: Modern air warfare relies heavily on Airborne Early Warning and Control aircraft and mid-air refuelers. By positioning Kusha systems near border areas, the Indian Air Force can force these high-value targets to operate hundreds of kilometers behind enemy lines, limiting their effectiveness.
- Stopping Stand-off Precision Strikes: Adversaries often launch standoff cruise missiles from outside the range of traditional air defenses. Kusha can track and destroy these incoming missiles at long distances before they reach critical targets.
- Area Denial: Deploying mobile Kusha units allows commanders to create temporary no-fly zones over specific battlefields or strike groups, protecting ground forces from enemy air sweeps.
The Road to Operational Deployment
With its successful maiden flight-test, Project Kusha enters an intensive flight trial phase. The success of this trial reduces India’s long-term reliance on foreign suppliers for strategic missile shields.
Over the coming years, DRDO will conduct additional firing tests for the longer-range M2 and M3 interceptor variants. Phased induction into active military service is targeted to begin between 2028 and 2030, reinforcing national air security through domestic innovation.
