India Develops First Indigenous 350 kg Turbojet Engine, Boosting Aatmanirbhar Bharat

India has developed its first indigenous 350 kg thrust-class expendable turbojet engine, marking a major milestone in the country’s defence aviation programme. Designed by the Gas Turbine Research Establishment (GTRE) under the Defence Research and Development Organisation (DRDO) and manufactured by Azad Engineering, the engine is intended for missiles, Unmanned Aerial Vehicles (UAVs), and anti-drone systems.

Why Indigenous Turbojet Engines Matter

Modern missiles and military drones rely on compact, high-performance engines to travel long distances with speed and precision. Developing such engines is one of the toughest challenges in aerospace engineering, and only a few countries have mastered this capability.

What Is an Indigenous 350 kg Turbojet Engine?

A turbojet engine generates thrust by compressing air, mixing it with fuel, and releasing high-speed exhaust gases. The 350 kg thrust class indicates the engine’s power output, while “indigenous” means it has been designed and built within India.

What Has Been Announced?

India has successfully completed the development and delivery of its first indigenous expendable turbojet engine in the 350 kg thrust class. The programme was completed in just 24 months, marking a significant step in India’s ability to develop advanced propulsion systems for defence applications.
