Vivace-built propulsion hardware supported both TA-1 and TA-2 during successful powered and hypersonic tests in the past year.
The TA-2 vehicle exceeded Mach 5 again in March 2025, confirming reusability and advancing the goals of the MACH-TB programme.
Primary objectives for the flight test included accomplishing safe air-launch release of the TA-1 vehicle, engine ignition, acceleration, sustained climb in altitude, and a controlled water landing.
While the company had conducted several successful ground tests fueling and igniting the system, it needed to evaluate how the system performs in the flight environment prior to release.
The ongoing flight test program continues on target towards separation test and the first hypersonic flight of TA-1 within the first half of 2023.
Stratolaunch's Roc aircraft took off from Mojave Air and Space Port on October 28 during its first captive carry flight with the Talon-A separation test vehicle, TA-0. This was the eighth flight of the Roc aircraft.
GNC software commissioned from Draper in 2020 has now been installed on the Talon-A. Draper has long experience, having worked on the Apollo program, Space Shuttle missions and the International Space Station.
Stratolaunch's Roc carrier aircraft has completed its fourth flight test. The primary mission objective was to fully retract and extend the aircraft's landing gear for the first time.
Launched from Stratolaunch's Roc carrier aircraft, the Talon-A is a rocket-propelled, autonomous, reusable testbed carrying customisable payloads at speeds over Mach 5.
Talon-A is a fully reusable, autonomous, liquid rocket-powered Mach 6-class vehicle which can provide over 60 seconds of hypersonic flight test conditions. It needs a monster carrier aircraft to get it airborne.
The Talon-A is designed to fly at speeds up to Mach 6, and will now feature a composite fuel probe from LMS and a signal conditioner unit that will communicate fuel quantity to the avionics over an ARINC 429 bus.
