Stratolaunch Completes Vital Test of Launch System for Hypersonic Vehicles

The flight, which took place over the Vandenberg Space Force Base's western range off the central coast of California, was the 11th test sortie for Roc and the second time the group has carried out flight operations at Vandenberg.

Stratolaunch said the flight lasted four hours and eight minutes and showed the Talon-A system “can cleanly and safely separate hypersonic vehicles from Roc's center-wing pylon.” The test also confirmed communications between the test vehicles and the ground were working properly for data collection during planned hypersonic flights.

"Today's test was exceptional," said Dr. Zachary Krevor, Stratolaunch president and CEO. "It was exhilarating to see TA-0 release safely away from Roc, and I commend our team and partners. Our hardware and data collection systems performed as anticipated, and we now stand at the precipice of achieving hypersonic flight."

With this test complete, according to Stratolaunch, its team will move toward its next major goal of achieving hypersonic flight with the TA-1 expendable testbed vehicle, progressing toward its first hypersonic flight of the TA-1 late this summer.
