Yes. Scramjet engines are real and have been tested in multiple research and defense programs. Green Launch specifically notes a series of nine hypersonic combustion ramjet launches with SHARP and reports free-flying scramjet operation at Mach 8, exceeding an earlier Mach 5.5 record. These tests show scramjets can operate in extreme high-speed flight when supported by the right launch conditions.
