January 8, 2026: The high-speed aircraft manufacturer Hermeus transferred development of its Quarterhorse Mk 2.1 to Spaceport America. Next steps will include reintegration of the tail and wings to the fuselage, ground operations and system checks, engine ground runs, taxi tests, and then preparation for first flight. Quarterhorse Mk 2 is designed to de-risk uncrewed supersonic flight and will enable both "high-cadence hypersonic flight test and novel operational defense capabilities."
