India’s Hypersonic Scramjet Engine Passes Major Test

India’s defense agency DRDO successfully tested a hypersonic scramjet combustor engine for over 1,200 seconds (around 20 minutes) in Hyderabad. This was a major improvement over an earlier 700-second test conducted in January 2026. �

The test is important because scramjet engines are used for hypersonic cruise missiles that can travel faster than Mach 5 while remaining maneuverable, making them difficult for current air-defense systems to intercept. �

The engine uses “active cooling” technology to survive the extreme heat generated at hypersonic speeds. DRDO scientists also developed:
A special flame-stabilization system to keep combustion stable at ultra-high speeds
Advanced ceramic thermal barrier coatings that can withstand temperatures beyond steel’s melting point
An indigenous liquid hydrocarbon fuel that improves cooling and ignition performance �

Officials said the successful ground test strengthens India’s hypersonic cruise missile program and pushes the country further into advanced aerospace and next-generation military technology. �
