DRDO Demonstrates SFDR Missile Technology
The Defence Research and Development Organisation has successfully demonstrated Solid Fuel Ducted Ramjet (SFDR) technology, marking a major milestone in India’s long-range air-to-air missile development programme.
Successful Flight Demonstration
The technology demonstration was carried out from the Integrated Test Range at Chandipur in Odisha. During the test, key subsystems including the nozzle-less booster, SFDR combustor and fuel flow regulation systems performed as designed. The test validated the transition from booster phase to sustained ramjet-powered flight.
What SFDR Enables
SFDR is an air-breathing propulsion system that allows missiles to sustain thrust at high speeds by using atmospheric oxygen. Compared to conventional rocket motors, it enables longer range, higher speed and improved manoeuvrability, significantly enhancing air combat capability.
Strategic Significance
With this successful demonstration, India joins a small group of countries that have mastered SFDR technology. The system is expected to power future long-range air-to-air missiles for the Indian Air Force, strengthening indigenous defence capabilities and reducing reliance on imported propulsion systems.
The development is seen as a key step towards next-generation missile systems and improved aerial deterrence.
