Major breakthrough in Hypersonic Missile development: DRDO conducts extensive long-duration test of Actively Cooled Full Scale Scramjet Combustor

• DRDL (Hyderabad) of DRDO sustained an Actively Cooled Full-Scale Scramjet Combustor for >1,200 seconds on 9 May 2026, a global-class endurance for ground-tested air-breathing hypersonic propulsion.
• Lays the propulsion foundation for India's indigenous Hypersonic Cruise Missile (HCM) programme (Mach >5 class).
• High examinable yield: ministry, lab, facility, fuel chemistry, materials and dates are all MCQ-ready.
