Stratolaunch TA-1 Hypersonic Test Vehicle Completes First Powered Flight

Stratolaunch said the main objectives of the test on March 9 included the basic phases of the TA-1’s flight, such as a safe release from the Roc air-launch aircraft, followed by engine ignition, acceleration, and sustained climb in altitude. The flight concluded with a controlled water landing. 

“[It] was a great day for the Stratolaunch team,” said Zachary Krevor, president and CEO of Stratolaunch. “I am extremely proud of their perseverance to reach this point. The successful outcome of the test is a direct result of the team’s technical prowess and professionalism.” 

While the company said the flight met all of its objectives, it declined to share specific altitude and speed information from the test because of certain agreements with customers. Krevor revealed that the TA-1 “reached high supersonic speeds approaching Mach 5” and collected valuable data. The test took place at the Mojave Air & Space Port in Mojave, California.

“Our goal with this flight was to continue our risk reduction approach for TA-2’s first reusable flight and be steadfast on our commitment of delivering maximum value to our customers,” Krevor said. “We are excited to review the data from today’s test and use it as we plan our next steps toward TA-2’s first flight later this year."

As TA-1 testing continues, Stratolaunch is moving ahead with the manufacture of the TA-3, the second fully reusable vehicle in the Talon-A family. The company said it is also working on modifications to its additional launch platform, a Boeing 747-400 called the Spirit of Mojave.
