The Scramjet Market Size is Anticipated to Exceed USD 90 Billion by 2033, Growing at a CAGR of 4.49% from 2023 to 2033. The term scramjet, which stands for "supersonic combustion ramjet," refers to a sophisticated class of jet engine designed for effective operation at hypersonic speeds, usually higher than Mach 5. Scramjet engines rely on the vehicle's velocity to compress incoming air, in contrast to conventional jet engines that use turbines for this purpose.
