Hermeus has completed tests of its first Quarterhorse hypersonic unmanned aerial vehicle (UAV) – a ground test article dubbed “Mk 0”, according to a statement by the company. The ground tests are intended to pave the way for flight-testing later in 2024.

Testing of what the company calls its “dynamic iron bird” took place at the US Air Force’s (USAF’s) Arnold Engineering Development Complex in Tullahoma, Tennessee, over a 37-day time span. Among other tasks, the craft demonstrated ground-handling qualities of integrated subsystems, taxiing, and lost-link behaviour.

The vehicle was designed and constructed in six months, according to Hermeus.

“This was the first time our flight test team had an opportunity to work in a deployed test campaign with external stakeholders,” Don Kaderbek, Hermeus’ vice-president of test, said in a statement. “The more the team works together and establishes their battle rhythm, the smoother flight-testing will go.”
