What Project Kusha is
Project Kusha (also known as the Extended Range Air Defence System, ERADS) is an indigenous surface‑to‑air missile programme led by India’s Defence Research and Development Organisation (DRDO) for the Indian Air Force and Indian Navy. It is designed as a mobile, long‑range air‑defence shield capable of detecting, tracking, and intercepting a wide range of aerial threats, including fighter jets, drones, cruise missiles, and certain ballistic‑missile‑class targets.
Core capabilities and design
The system is structured as a multi‑tier, long‑range air‑defence net, with at least three interceptor variants (often labelled M1, M2, and M3), each tuned for different engagement ranges and altitude regimes. Typical reported ranges are roughly 150 km for M1, around 250 km for M2, and 350–400 km for M3, giving India a 3‑layer shield that can engage threats at varying distances from the defended area. The system is expected to integrate with India’s Integrated Air Command and Control System (IACCS) and allied radars, enabling a network‑centric battlespace picture and coordinated engagements across large sectors of airspace.
How it strengthens India’s air defence
By providing a long‑range, area‑defence umbrella, Project Kusha aims to bridge the gap between India’s existing medium‑range systems (like the MR‑SAM / Akash family at about 80 km) and heavy‑weight imports such as the Russian S‑400 that can reach up to about 400 km. In practice, this means Kusha can push the outer edge of India’s defensive cordon further out, giving decision‑makers more time to react to incoming raids and allowing other assets to focus on closer‑in threats.
Why it reduces foreign reliance
India has historically depended on foreign long‑range air‑defence systems for high‑altitude and long‑range coverage, which introduces import‑driven risks in maintenance, upgrades, and data‑access control. Project Kusha, being a domestically designed and produced platform, gives India full ownership of the design, software, and logistics chain, cutting procurement‑related strategic dependence on external suppliers. The system is also being positioned as a potentially more cost‑efficient alternative to platforms like the S‑400 or Patriot, making it attractive not just for India but also for export‑market partners looking for a “Made‑in‑India” high‑end air‑defence option.
Strategic and regional impact
Once fully inducted (with phased roll‑out expected between 2028 and 2030), Project Kusha is expected to become a key pillar of India’s layered air‑defence doctrine, anchoring protection around major cities, command hubs, and critical infrastructure. By fielding its own 400‑km‑class shield, India signals that it can now manage sophisticated air‑and‑missile‑defence independently, without being forced into lopsided deals or compromised access to mission‑critical algorithms. This not only enhances deterrence in a tense neighbourhood but also reinforces India’s broader push for defence self‑‑reliance under the Atmanirbhar Bharat framework.
