Defence Research and Development Organisation (DRDO) has conducted a successful ground test of full scale actively cooled long-duration Scramjet Engine for the Hypersonic Missile Programme. Defence Ministry in a statement today said that Defence Research and Development Laboratory (DRDL), the Hyderabad-based laboratory of DRDO, achieved a run time of over 12 minutes at its state-of-the-art Scramjet Connect Pipe Test (SCPT) Facility. Hypersonic Cruise Missile is capable of exceeding five times the speed of sound, over 6,100 kilometres per hour, for extended periods.
The remarkable feat is achieved through a cutting-edge air-breathing engine, which utilises supersonic combustion to sustain long-duration flight. The ground-tests conducted at the SCPT facility have successfully validated the design of the advanced scramjet combustor, as well as the capabilities of the state-of-the-art test facility.
The Combustor and test facility were designed and developed by the DRDL and realised by industry partners. The successful test positions India at the forefront of advanced aerospace capabilities. This significant achievement builds upon the earlier subscale test conducted on April 25, 2025, for long duration, marking a crucial step forward in Hypersonic Missiles development.
Defence Minister Rajnath Singh complimented DRDO, industry partners and academia on the successful ground test of the Full Scale Actively Cooled Long Duration Scramjet Engine. He said that the achievement is a solid foundation for the nation’s Hypersonic Cruise Missile Development Program.
