MOJAVE, Calif. (Stratolaunch PR) — Stratolaunch announces the completion of its seventh flight test of Roc, the world’s largest flying aircraft. The aircraft flew for 3 hours and 1 minute over the Mojave Desert and reached an altitude of 27,000 feet (8200 meters), a new altitude record for the aircraft. 

The seventh flight focused on continuing Roc’s flight envelope expansion with the recent addition of the pylon on the aircraft’s center wing. Test objectives included:

  • Demonstration of increased maximum altitude capability
  • Continued validation of the aircraft’s general performance and handling characteristics, with the addition of the recently installed pylon hardware
  • Continued validation of landing gear operations including door functionality, and alternate gear extension

“Today’s flight is a success story of the Stratolaunch team’s ability to increase operational tempo to the pace desired by our customers for performing frequent hypersonic flight test,” said Dr. Zachary Krevor, Stratolaunch Chief Executive Officer and President. “Furthermore, the team reached a new altitude record of 27,000 feet, thereby demonstrating the aircraft performance needed for our Talon hypersonic vehicle to reach its wide design range of hypersonic conditions.”

The Stratolaunch team recently integrated the TA-0 separation test vehicle with the carrier aircraft for the first time, signaling a priority push toward captive carry and separation testing happening later this year. The company is also making solid progress on system integration of its first hypersonic flight test vehicle, TA-1 and on the fabrication of a third vehicle, TA-2, the first fully reusable hypersonic test vehicle. The company anticipates delivering hypersonic flight services to government and commercial customers in 2023.
