Hermeus Begins Taxi Tests of Quarterhorse Mk 2.1 Supersonic Aircraft at Spaceport America
Hermeus has initiated taxi tests for its Quarterhorse Mk. 2.1 supersonic demonstrator at Spaceport America in New Mexico. This remotely piloted aircraft, powered by Pratt & Whitney's F100-229 engine, is designed for high supersonic speeds and aims to serve as a high-Mach unmanned aircraft for national defense. The Mk. 2.1 will be used by Kratos Defense for the U.S. Navy's MACH-TB program, with extensive flight tests anticipated following successful taxi evaluations.

Hermeus has started taxi tests for its Quarterhorse Mk. 2.1 supersonic flight demonstrator at Spaceport America, New Mexico. The aircraft, remotely piloted and powered by a Pratt & Whitney F100-229 engine, is designed for high supersonic speeds and will be used by Kratos Defense for the U.S.
Navy's MACH-TB program. The testing phase includes validating ground handling, braking, and systems integration. Future flight tests will provide insights for the Mk. 3 version, which will utilize a complete TBCC propulsion system. Extensive flight tests are expected, surpassing those of the previous Mk. 1 demonstrator.
