Stratolaunch's Talon-A, shown here in an artist's concept, is one of several new hypersonic vehicles to be launched from the company's massive carrier plane, the world's largest aircraft.
Stratolaunch's website now reveals that the company has reinvented itself as a builder, tester and operator of hypersonic vehicles those that can travel at least five times the speed of sound , or Mach 5.
The huge plane is key to this new mission, hauling vehicles aloft to test various payloads in the extreme environments imposed by hypersonic flight.
In August 2018, before Allen's death, Stratolaunch announced plans to use four different satellite-launching vehicles with the huge aircraft, including an orbital space plane.
The Stratolaunch Carrier has just one flight under its belt, a 2.5-hour test flight that took place in April 2019.
