Answer: Defence Research and Development Organisation (DRDO)
Notes: Defence Research and Development Organisation (DRDO) successfully tested an Active Cooled Scramjet Combustor for 120 seconds. Scramjets, an upgrade to ramjets, generate thrust via supersonic airflows and combustion. They operate at hypersonic speeds, exceeding Mach 5 (over 5,400 km/hr). Hypersonic missiles can bypass air defense systems for rapid, high-impact strikes. Countries like the USA, Russia, India, and China are advancing hypersonic technology. Scramjets are air-breathing engines sustaining supersonic combustion without moving parts. Defence Research & Development Laboratory (DRDL), a DRDO lab in Hyderabad, developed this scramjet-powered hypersonic technology. This milestone boosts hypersonic missiles, fast air transport, and low-cost satellite launches.
