Hypersonic aircraft developer Hermeus took the wraps off its first flying prototype, Quarterhorse Mk 1, this week as it moves to initial flight testing later this year. Built and integrated over the past seven months, Quarterhorse Mk 1 follows the completion of the ground-test campaign late last year of the initial non-flying, fully integrated prototype, dubbed Quarterhorse Mk 0. Development of Mk 1 keeps Hermeus on pace for developing one aircraft a year, a target the Atlanta-based company has set for itself.

Powered by a GE J85 engine, the uncrewed, remotely piloted Quarterhorse Mk 1 will demonstrate high-speed takeoff and landing, which Hermeus called a “key enabling capability to the future hypersonic aircraft.” Plans call for those trials to take place at Edwards Air Force Base.
