The world's biggest plane broke another milestone after it flew with a fully-fueled hypersonic vehicle prototype for the first time.
Stratolaunch's Roc took to the air on Saturday carrying its TA-1 Talon-A hypersonic vehicle, fuelled with live propellant. This was a "significant step" forward in Talon-A's development, the company said in a statement.
"While we have conducted several successful ground tests fueling and igniting the system, we needed to evaluate how the system performs in the flight environment prior to release," said Zachary Krevor, chief executive for Stratolaunch.
The company plans to eventually use Talon-A to help the US military test components at hypersonic speeds, according to The Defense Post.
Initial results from Saturday's flight, which lasted three hours and 22 minutes, showed the Talon-A's propulsion system "performed as predicted" while fully formed during the flight.
The company will review the data before determining the next steps but stated it aims to conduct a fully powered test flight of the Talon-A vehicle in the "near term."
Roc is Stratolaunch's carrier system, a mothership designed to bring heavy payloads like planes and rockets to the air. With its 385-foot-wide wingspan and six Boeing 747 engines, it can carry up to 500,000 pounds under its wings.
But after Allen died in 2019, the company focused its efforts on hypersonic research, developing vehicles that aim to fly at least five times faster than the speed of sound, per Space.com.
The company has also teased the development of other lines of vehicles called Talon+ and Space Plane, though it has not released more information about the projects.
