Project Kusha: India’s Next-Gen Air Defence System Explained

What is Project Kusha?
Project Kusha, also known as the Extended Range Air Defence System (ERADS), is a cutting-edge missile defence initiative by DRDO. It is designed to:
Detect and destroy stealth aircraft, drones, cruise missiles, and hypersonic threats.
Operate at three interception ranges: 150 km, 250 km, and 400 km.
Integrate advanced radars for superior detection and targeting.
Strengthen India’s self-reliance in defence technology, reducing dependency on foreign systems like Russia’s S-400.

Why is Project Kusha a Game-Changer?
Indigenous Development – Unlike imported systems, Project Kusha is 100% Made in India, boosting the Atmanirbhar Bharat initiative.
Multi-Layered Defence – It will work alongside other systems like Akash and Barak-8, creating a comprehensive air shield.
Export Potential – Once proven, India can export this system to friendly nations, enhancing strategic partnerships.
Cost-Effective – At ₹21,700 crore, it is a budget-friendly alternative to expensive foreign imports.
Future-Ready – Designed to counter hypersonic missiles, it ensures India stays ahead in defence technology.


Project Kusha vs Global Systems (S-400 & Iron Dome)
While Russia’s S-400 has a 400 km range, Project Kusha aims to match its capabilities with indigenous technology. Key differences:
S-400 is battle-tested but expensive and imported.
Iron Dome (Israel) excels against short-range rockets but lacks long-range interception.
Project Kusha offers customization, cost benefits, and strategic independence.


Why is Project Kusha Important for Competitive Exams?
Defence projects like Project Kusha are frequently asked in UPSC, SSC, PSC, NDA, CDS, and CAPF exams. Understanding its technology, strategic impact, and comparison with global systems helps in:
Current Affairs (Defence & Security)
Science & Technology (Missile Systems)
International Relations (India’s Defence Exports)
