India has made a significant leap towards military self-reliance following the successful completion of the first development trials for Project Kusha, the nation's indigenous long-range air defence system.
According to recent reports, the Defence Research and Development Organisation (DRDO) and its key industry partner, Bharat Electronics Limited (BEL), have successfully wrapped up ground validations, including critical trials for the dual-pulse rocket motor.
This progress means the programme has moved beyond preliminary design and is now preparing for crucial integrated flight tests expected in 2026.
Officially designated as the Extended Range Air Defence System (ERADS), Project Kusha is designed to be India's homegrown equivalent to advanced systems like the Russian S-400 and S-500.
Approved by the Cabinet Committee on Security with a budget of approximately ₹21,700 crore, the initiative aims to build a robust, multi-layered shield over vital military assets and cities.
It is engineered to detect and neutralise a wide array of aerial threats, ranging from stealth jets and drones to cruise missiles.
By offering overlapping layers of protection, the system will allow armed forces commanders to heavily restrict enemy movement in Indian airspace.
At the heart of this new defence architecture are three distinct interceptor missiles, which will share a common kill vehicle but feature different booster stages to tackle threats at varying distances.
The primary missile, known as the M1, is built to intercept targets up to 150 kilometres away, effectively neutralising tactical fighters and precision weapons. DRDO has already fabricated this variant and verified its subsystems, setting the stage for its maiden flight test.
The second layer of the shield relies on the M2 interceptor, which extends the protective radius to approximately 250 kilometres.
This mid-tier variant bridges the gap between medium- and long-range capabilities, maintaining high accuracy through advanced tracking technologies like Active Electronically Scanned Array (AESA) seekers.
Ongoing development continues in tandem, focusing on enhancing propulsion systems to ensure it can effectively hunt down highly agile and evasive targets.
Serving as the outermost barrier, the M3 variant is designed to strike high-value enemy assets—such as airborne early warning aircraft, mid-air refuellers, and certain ballistic missiles—at distances exceeding 350 to 400 kilometres.
By developing these three complementary interceptors, DRDO is creating a highly survivable defence grid where each tier reinforces the others.
With initial ground validations complete, the immediate focus is on conducting integrated flight evaluations for the M1 missile.
Following these tests, progressive trials for the M2 and M3 variants will occur sequentially.
The Indian Air Force has already shown immense confidence in the project by securing an Acceptance of Necessity for multiple squadrons.
While early components of the system are anticipated to be operational by 2028, full deployment of all three layers is firmly targeted for 2030.
From a broader strategic perspective, Project Kusha is a cornerstone of 'Mission Sudarshan Chakra,' an ambitious plan to establish a comprehensive, nationwide air and missile defence grid by 2035.
Working in tandem with other homegrown systems such as the Akash-NG and Ballistic Missile Defence network, Kusha will heavily reduce India's reliance on foreign platforms.
This unified approach is expected to not only deter regional adversaries but also open future avenues for India to export cutting-edge military technology.
