Hermeus conducted testing of its iron bird Quarterhorse Mk 0_0 at the Arnold Engineering Development Complex (AEDC) in Tullahoma, Tennessee, enabling the company to work directly with U.S. Air Force personnel.

Hermeus completed testing of its first fully integrated vehicle, Quarterhorse Mk 0, a non-flying prototype used as a “dynamic iron bird” for testing subsystems of what would become a hypersonic aircraft.

Mk 0 is one of four test vehicles in the Quarterhorse program, involving the development of a subscale hypersonic aircraft that will test the company’s Chimera engine, reach speeds of Mach 4, and refine concepts for future civil and military hypersonic aircraft.
