First steps are hard. They require careful planning, calculated risk, and most of all, courage. We took a daring first step earlier this month with the completion of TA1’s first powered flight, reaching high supersonic speeds approaching Mach 5. The flight was a landmark moment on our path to providing our customers and nation a reusable and routine hypersonic test capability. Congratulations to the Stratolaunch team and our partners on this achievement! Stay tuned on our progress as we prepare to fly our first fully reusable TalonA vehicle, TA2, later this year.
