India's Jet Engine Breakthrough

India has successfully unveiled its first fully indigenous expendable turbojet engine, marking a major milestone in defence technology.

Designed Entirely in India

The engine was designed by DRDO's Gas Turbine Research Establishment (GTRE) and manufactured by Hyderabad-based Azad Engineering.

What Makes It Special?

This is India's first completely indigenous expendable turbojet engine, designed, manufactured and assembled within the country.

350 kg Thrust Engine

The engine produces around 350 kg of thrust (about 3.5 kN), making it suitable for modern missile and drone applications.

What Does 'Expendable' Mean?

Unlike aircraft engines, expendable turbojet engines are designed for a single mission. Once the missile or drone reaches its target, the engine is destroyed along with it.

Why Turbojet Instead of Rocket?

Turbojet engines use oxygen from the atmosphere instead of carrying an oxidizer, making them lighter, more fuel-efficient and ideal for long-range cruise missiles.

Where Will It Be Used?

Experts believe the engine could power: – Long-range cruise missiles – Jet-powered UAVs – Kamikaze drones – Decoy systems Official deployment details have not yet been announced.

Why It Matters

India can now reduce dependence on imported engines, strengthen defence self-reliance and improve supply security during future conflicts.

Built on Years of Research

Technologies developed during the Kaveri engine programme helped GTRE gain expertise in metallurgy, turbine blades and engine design, contributing to this achievement.
