The Road to High-Mach

Rather than trying to create a fully operational high-Mach aircraft in one step, we’re building a series of increasingly capable aircraft. Each aircraft is purpose-built to solve a defined set engineering problems, validate critical systems, and reduce technical risk for the next one we build. That roadmap is Quarterhorse.
