Raghu Vamsi Unveils Flight-Ready Indra Series Turbojet Engines For Target Drones, Loitering Munitions, And Unmanned Combat Systems
Hyderabad-based aerospace manufacturer Raghu Vamsi has successfully launched
its Indra Series Turbojet Engines, marking a significant leap toward complete
self-reliance in small jet propulsion technology.
The company announced that the engines are 100% designed, developed, and
manufactured in India, reinforcing the nation’s “Atmanirbhar Bharat”
initiative in the aerospace and defence domains.
The Indra engine series, aimed at powering target drones, loitering munitions,
and unmanned combat systems, represents a major step in India’s indigenous
propulsion capabilities. Raghu Vamsi’s design integrates advanced
high-temperature alloys, fuel-efficient combustion architecture, and
lightweight composite materials to ensure high thrust-to-weight ratios and
operational durability under demanding conditions.
These flight-ready turbojets reportedly underwent rigorous endurance and
flight validation tests, demonstrating consistent thrust performance and fuel
efficiency across varied altitudes. The company collaborated with leading
Indian test facilities to achieve certification benchmarks comparable with
global propulsion standards.
With the Indra line entering production, Raghu Vamsi positions itself as a key
private-sector contributor to India’s defence and aerospace engine technology
ecosystem. The firm is expected to supply these engines for upcoming
programmes involving indigenous drone swarms and subsonic cruise platforms,
reducing dependency on foreign engine imports.
