• What? Long-duration ground test of full-scale actively cooled scramjet engine
• Who? Defence Research and Development Organisation (DRDO)
• Where? Scramjet Connect Pipe Test (SCPT) Facility, Hyderabad (Telangana)
• Lab: Defence Research and Development Laboratory (DRDL)
• Purpose: Development of Hypersonic Cruise Missile capability
• Speed: Over Mach 5 (exceeding 6,100 km/h)
• Test Duration: Over 12 minutes
• Technology: Air-breathing supersonic combustion ramjet (scramjet) with active cooling.

About Scramjet Test:
Performance: The combustor operated for over 12 minutes, validating sustained supersonic combustion and test infrastructure performance.
Technology: The air-breathing scramjet engine uses supersonic combustion and active cooling to enable hypersonic flight beyond Mach 5.
Development: The combustor and facility were indigenously designed and developed by DRDL with support from industry and academia.
Capability: The technology supports hypersonic cruise missiles exceeding 6,100 kilometers per hour (km/h), with high maneuverability and low-altitude flight that complicates interception.
Validation: The test confirmed both the advanced combustor design and the performance of state-of-the-art hypersonic test infrastructure.
Progressive Scramjet Tests: Earlier ground tests, including a 120-second run (January 2025) and a 1,000-second endurance test (May 2025), gradually scaled up scramjet technology, strengthening India’s regional deterrence.
About Defence Research and Development Organization (DRDO):
DRDO was formed by merging the Technical Development Establishments (TDEs) of the Indian Army(IA), the Directorate of Technical Development & Production (DTDP), and the Defence Science Organisation (DSO).
