About the Company

Hermeus

Develops hypersonic defense aircraft and engines

Hermeus designs and builds high-Mach and hypersonic aircraft for defense, using uncrewed test platforms and a reusable propulsion system. Its core approach centers on the Quarterhorse testbed and the Chimera engine, a turbine-based combined cycle that starts in a turbojet mode for runway takeoff and transitions to a ramjet for speeds above Mach 5. The company differentiates itself with rapid, hardware-focused prototyping drawn from a spaceflight background and a clear path to production through government contracts with the DoD, DIU, and ABMS programs. Its near-term goal is to mature Quarterhorse and Darkhorse into production-capable systems for defense missions, while its long-term vision includes Halcyon, a 20-seat commercial airliner flying transatlantic routes in about 90 minutes.
