Hermeus is an Atlanta-based aerospace company focused on developing hypersonic aircraft for both military and commercial applications. The company's primary goal is to create reusable aircraft capable of reaching speeds of Mach 5 (over 3,000 miles per hour) or higher. Hermeus' technology is centered around its proprietary Chimera engine, a turbine-based combined cycle (TBCC) engine that integrates a turbojet for low-speed flight and a ramjet for high-speed operations. This innovative propulsion system allows for seamless transition between different speed ranges, enabling aircraft to take off from standard runways, reach hypersonic speeds, and land conventionally.

The company is currently developing a series of unmanned aircraft prototypes called Quarterhorse to demonstrate and refine its hypersonic technology. In March 2024, Hermeus unveiled its first flyable aircraft, the Quarterhorse Mk 1, which is expected to undergo flight tests at Edwards Air Force Base later in the year. This prototype is powered by a General Electric J85 engine and is designed to test high-speed takeoffs and landings. The company plans to progress through iterations, with the Quarterhorse Mk 2 aimed at achieving supersonic flight in 2025 using a modified Pratt & Whitney F100 engine.

Hermeus' long-term vision includes developing two primary aircraft: Darkhorse, an unmanned hypersonic vehicle for defense applications, and Halcyon, a commercial passenger aircraft capable of flying from New York to London in 90 minutes. The company's approach focuses on iterative development and cost-effective manufacturing, including the use of 3D printing for some components.
