DRDO’s 1,200-Second Scramjet Test Marks Major Step in India’s Hypersonic Missile Programme
A scramjet, or supersonic combustion ramjet, is an air-breathing engine designed for flight at hypersonic speeds, generally above Mach 5. Unlike conventional rocket motors that carry both fuel and oxidiser, a scramjet uses oxygen from the atmosphere, allowing sustained high-speed flight in the atmosphere. This makes the technology highly valuable for long-range hypersonic cruise missiles, where speed, manoeuvrability and reduced reaction time for enemy air-defence systems are crucial.
