DRDO’s Hypersonic Missile Actively Cooled Scramjet Combustor.
DRDO tests Actively Cooled Full Scale Scramjet Combustor for hypersonic missiles: New Delhi, May 9: India has marked a significant milestone in the development of next-generation hypersonic missile technology, with the Defence Research and Development Organisation (DRDO) successfully conducting an extensive long-duration ground test of an Actively Cooled Full Scale Scramjet Combustor.
The test, carried out by the Defence Research & Development Laboratory (DRDL) in Hyderabad on May 9, achieved a run-time of more than 1,200 seconds at the state-of-the-art Scramjet Connect Pipe Test (SCPT) Facility. The achievement represents a major leap in India’s efforts to develop advanced hypersonic cruise missile systems capable of operating at extremely high speeds.
The latest accomplishment builds upon an earlier successful test of over 700 seconds conducted in January this year, reflecting rapid progress in the country’s indigenous hypersonic propulsion programme.

Indigenous Technology Powers Hypersonic Ambitions
Officials said the scramjet combustor was designed and developed by DRDL with support from Indian industry partners, underlining the growing role of domestic collaboration in strategic defence technologies.
The successful test validated critical technologies associated with supersonic air-breathing propulsion systems, widely regarded as one of the most complex areas in aerospace engineering. The engine utilises an indigenously developed liquid hydrocarbon endothermic fuel system, high-temperature thermal barrier coatings, and advanced manufacturing techniques.
Scientists involved in the programme said the extensive ground-testing at the SCPT facility confirmed both the design efficiency of the actively cooled scramjet combustor and the operational capabilities of the sophisticated testing infrastructure.
Hypersonic systems, which can travel at speeds exceeding Mach 5, are considered a transformative technology in modern warfare due to their speed, manoeuvrability, and ability to evade conventional missile defence systems.

India Moves Closer to Advanced Hypersonic Missile Capability
The successful long-duration test is being viewed as a crucial step toward the development of indigenous hypersonic cruise missiles, placing India among a select group of nations pursuing advanced hypersonic weapon technologies.
Defence analysts say the development strengthens India’s strategic deterrence capabilities and demonstrates the country’s growing expertise in advanced aerospace systems amid evolving global security challenges.
Defence Minister Rajnath Singh congratulated DRDO, industry partners, and academia for the successful ground-test of the Full Scale Actively Cooled Long Duration Scramjet Engine. He described the achievement as a strong foundation for India’s Hypersonic Cruise Missile Development Programme.
Secretary, Department of Defence R&D and DRDO Chairman Dr Samir V Kamat also congratulated the scientists, engineers, and teams associated with the successful test.
The breakthrough further reinforces India’s push towards self-reliance in critical defence technologies and highlights the country’s expanding capabilities in futuristic missile and aerospace systems.
