Stratolaunch’s Roc Drops Talon Hypersonic Vehicle in Successful Test Flight

The first drop test of Stratolaunch’s Roc carrier plane was successfully conducted. The Roc released the Talon hypersonic vehicle prototype high above the Pacific Ocean. The representatives of Stratolaunch expressed satisfaction with the test and are preparing for future ambitious tests.

Zachary Krevor, the CEO and president of the company, announced plans for the first hypersonic flight in late fall. A significant milestone in its pursuit of super-speed travel has been reached by Stratolaunch. The Roc released the Talon, a separation test vehicle, successfully on May 13, 2023. Possibly reaching Mach 5 to Mach 7, Tyson-AA has the potential to travel at supersonic speeds.

Marking the 11th flight for Stratolaunch‘s Roc launch platform, this flight was the first successful separation of a test vehicle. The clean and safe separation of hypersonic vehicles from Roc’s center-wing pylon was demonstrated by the test. During the test, telemetry between the vehicles and Vandenberg’s Space Force Base’s communication assets was confirmed.

For its 11th flight, Roc took off from the Mojave Air & Space Port in Southern California. Performing gliding maneuvers and sending telemetry back to the mission team, the Talon-O separation test vehicle was carried by Roc. Meeting all objectives, Talon-o touched down on the water as part of the flight plan.

Marking the completion of the landmark test, Roc successfully landed at Mojave after the flight. In late summer, the team is now progressing towards the first hypersonic flight of the TA-1 expendable test bed.

CEO and President of Stratolaunch, Dr. Zachary Krevor, praised the test as exceptional and emphasized the achievement of hypersonic flight. Although the Talon-O aircraft didn’t have an engine, it provided valuable data through gliding mane Ubers. Established in 2011 by Microsoft co-founder Paul Allen for air-launching rockets, the Stratolaunch shifted its vision to hypersonic research in 2019.

Air launch strategies for satellite and space tourism missions are also used by Virgin Orbit and Virgin Galactic. Expected in a few months, Saturday’s success brings Stratolaunch closer to its first hypersonic flight. New possibilities for the future of high-speed travel are opened by this exciting progress.
