The Defence Research and Development Organisation (DRDO) successfully conducted a long-duration test of its Actively Cooled Full-Scale Scramjet Combustor in Hyderabad. The test marks a significant advancement in India’s hypersonic missile development programme and strengthens the country’s indigenous aerospace capabilities.
Key Highlights of the Successful Test
The test was conducted by the Defence Research & Development Laboratory (DRDL), a Hyderabad-based laboratory of DRDO.
The scramjet combustor achieved a run-time of more than 1,200 seconds (around 20 minutes).
The latest test surpassed the earlier successful test of over 700 seconds conducted in January 2026.
The trial was carried out at the Scramjet Connect Pipe Test (SCPT) Facility in Hyderabad.
Importance of Scramjet Technology
Scramjet (Supersonic Combustion Ramjet) technology is considered essential for developing hypersonic cruise missiles that can travel at speeds greater than Mach 5.
The technology enables:
Extremely high-speed missile propulsion
Long-duration hypersonic flight
Improved missile manoeuvrability
Capability to evade advanced air defence systems
Significance for India’s Defence Sector
The successful test positions India among a select group of countries possessing advanced hypersonic propulsion technology. The development is expected to strengthen India’s strategic deterrence and indigenous defence manufacturing capabilities.
The Ministry of Defence stated that the test validated:
The design of the advanced scramjet combustor
Indigenous thermal management systems
Capabilities of the SCPT facility
India’s long-term hypersonic cruise missile programme
Technologies Used in the Development:
The scramjet combustor incorporates several advanced indigenous technologies, including:
Actively cooled engine systems
Endothermic hydrocarbon fuel technology
High-temperature thermal barrier coating
Advanced flame stabilization systems
