India Develops First Indigenous 350 kg Thrust Turbojet Engine
India achieves milestone in aero-engine tech, boosts defence self-reliance. DRDO-GTRE develops first indigenous turbojet engine.

India has successfully developed its first indigenous expendable turbojet engine in the 350 kg thrust class, a major milestone in the country's defence research and development. The engine, designed by the Defence Research and Development Organisation's (DRDO) Gas Turbine Research Establishment (GTRE), was manufactured and assembled by industry partner Azad Engineering.
The successful development of the engine marks a significant step forward in India's efforts to strengthen self-reliance in advanced aerospace and defence technologies. According to the Ministry of Defence, the engine was delivered to GTRE by Azad Engineering on July 22, representing the culmination of years of precision engineering, advanced manufacturing, and close collaboration between India's scientific and industrial communities.
GTRE had selected Azad Engineering as its industry partner for the manufacturing and assembly of the engine. The ministry noted that jet engine technology is mastered by only a handful of countries and is considered among the world's most complex engineering disciplines, requiring exceptional precision, advanced metallurgy, and stringent manufacturing standards.
The successful development and delivery of the engine based on DRDO's design demonstrate the growing technological capabilities of the Indian defence industry and its ability to manufacture highly sophisticated propulsion systems. The engine was formally handed over by Azad Engineering Chief Executive Officer Rakesh Chopdar to Distinguished Scientist and Director General (Aeronautical Systems) Dr K. Rajalakshmi Menon and Outstanding Scientist and Director, GTRE, Dr S.V. Ramanamurty.
Defence Secretary, Secretary of the Department of Defence R&D and DRDO Chairman Rajesh Kumar Singh congratulated GTRE and its industry partner on the achievement, saying the collaboration had been instrumental in transforming the vision of an indigenous expendable turbojet engine into a historic milestone for the country's aerospace and defence ecosystem.
The successful development of the engine is expected to further strengthen India's indigenous defence manufacturing capabilities and support the country's broader goal of achieving self-reliance in critical military technologies. This achievement reflects the country's commitment to reducing its dependence on foreign defence technologies and promoting indigenous research and development.
India's defence industry has been working towards achieving self-reliance in critical technologies, including aero-engine technology. The development of the indigenous turbojet engine is a significant step towards achieving this goal. The engine is expected to have a significant impact on the country's defence capabilities, enabling the development of advanced aerospace and defence systems.
In recent years, India has made significant progress in developing its defence manufacturing capabilities, with a focus on promoting indigenous research and development. The country has established several research and development institutions, including the DRDO, to promote the development of advanced defence technologies.
The successful development of the indigenous turbojet engine is a testament to the country's growing technological capabilities and its ability to manufacture highly sophisticated propulsion systems. This achievement is expected to have a significant impact on the country's defence industry, enabling the development of advanced aerospace and defence systems and promoting self-reliance in critical military technologies.
In conclusion, the development of India's first indigenous expendable turbojet engine is a major milestone in the country's defence research and development. The successful development and delivery of the engine demonstrate the growing technological capabilities of the Indian defence industry and its ability to manufacture highly sophisticated propulsion systems. This achievement is expected to further strengthen India's indigenous defence manufacturing capabilities and support the country's broader goal of achieving self-reliance in critical military technologies.
