Hyderabad’s Raghu Vamsi Unveils India’s Indigenous 40 KGF Micro Turbojet Engine at Paris Air Show

In a major achievement for India’s aerospace and defense industry, Hyderabad-based Raghu Vamsi Aerospace Group unveiled a fully indigenous 40 KGF micro turbojet engine at the prestigious 55th International Paris Air Show, held from June 16 to June 22. This development marks an important milestone for India’s journey towards self-reliance in critical aerospace propulsion technologies.

The newly launched 40 KGF (kilogram-force) turbojet engine has been specifically designed for use in unmanned aerial vehicles (UAVs) and cruise missiles. According to a statement from the company, the engine underwent successful performance testing at their Hyderabad facility in the presence of officials from the Defence Research and Development Organisation (DRDO).

This turbojet engine is part of a larger family of four indigenous engines with thrust capacities of 14 KGF, 19 KGF, 25 KGF, and 40 KGF. All these engines have been entirely designed, developed, and manufactured within India, reinforcing the country’s growing expertise in advanced aerospace propulsion systems.

Key Specifications of the 40 KGF Micro Turbojet Engine:

• Thrust: 40 kilogram-force

• Type: Micro turbojet engine

• Application: UAVs and cruise missiles

• Development & Testing: Conducted at Hyderabad facility with DRDO oversight

• Part of Indigenous Engine Series: 14, 19, 25, and 40 KGF models

“This engine represents a historic leap for Indian aerospace propulsion. It is the result of years of dedicated research and development, manufacturing precision, and a bold vision for self-reliant defense technologies,” said Vamsi Vikas, Managing Director of Raghu Vamsi Aerospace Group.

Adding strength to their aerospace capabilities, Raghu Vamsi recently acquired WMT Precision LLC, a 40-year-old aerospace manufacturing company based in Syracuse, USA. This American firm specializes in producing fuel nozzles for major international aerospace giants like Collins, Parker, and Honeywell. The acquisition has significantly enhanced Raghu Vamsi’s expertise in the field of critical aero engine components.

At the Paris Air Show, Raghu Vamsi also introduced another impressive product — the Astra 100, a jet-powered kamikaze fixed-wing UAV developed under its deep-tech brand ARROBOT. With a range of 200 kilometers and a top speed of 450 km/h, this UAV successfully completed flight trials earlier this year. Powered entirely by indigenous systems — including its flight control, propulsion, and telemetry systems — the Astra 100 sets a new standard for autonomous combat UAVs made in India.

To meet the growing demand for their expanding aerospace product line, Raghu Vamsi has announced plans for a state-of-the-art 250,000 sq ft manufacturing facility at Hardware Park in Hyderabad. This advanced production center is expected to become operational by early 2026, further strengthening India’s position in global aerospace manufacturing.

This breakthrough not only showcases India’s growing capabilities in indigenous aerospace technology but also positions Raghu Vamsi as a key player in the future of defense aviation and unmanned systems.
