The most important airplane ever constructed now has two flights underneath its belt.
Stratolaunch’s Roc service airplane, which is being groomed to haul hypersonic automobiles aloft, performed its second-ever check flight Thursday morning (April 29).
The large plane, which includes a wingspan of 385 ft (117 meters), took off from Mojave Air and House Port in southeastern California at 10:28 a.m. EDT (1428 GMT; 7:28 native California time) on a data-gathering shakeout cruise that lasted three hours and 14 minutes.

Roc reached a most altitude of 14,000 ft (4,267 m) and a high velocity of 199 mph (320 kph) throughout Thursday’s check flight, which Stratolaunch deemed successful.
“We’re very happy with how the Stratolaunch plane carried out right this moment, and we’re equally enthusiastic about how a lot nearer the plane is to launching its first hypersonic automobile,” Stratolaunch chief working officer Zachary Krevor mentioned throughout a postflight information convention right this moment.
Microsoft co-founder Paul Allen established Stratolaunch in 2011 with the concept Roc can be used to launch satellites in midair. However Allen died in October 2018 with out seeing that imaginative and prescient change into actuality, and even seeing the twin-fuselage Roc get off the bottom. The airplane did not make its first — and, till right this moment, solely — check flight till April 2019.
The corporate was bought in October 2019 to its present house owners, who recast Roc’s function. The airplane will now function a cellular launch platform for hypersonic automobiles, maneuverable craft that journey a minimum of 5 occasions sooner than the speed of sound.
Stratolaunch is creating its personal household of hypersonic automobiles, together with a reusable 28-foot-long (8.5 m) craft referred to as Talon-A, which would be the first to fly with Roc. However that will not occur for some time but; Roc must make a lot of extra solo flights first, firm representatives mentioned right this moment.
If all goes in response to plan, the primary drop assessments with Roc and a Talon-A check article will happen early subsequent yr. An expendable model of Talon-A will attain hypersonic speeds later in 2022, and the primary flight with the reusable Talon-A variant will comply with in 2023, mentioned Stratolaunch chief expertise officer Daniel Millman.
The info gathered throughout Talon-A flights may be of curiosity to the U.S. navy, which has been creating its personal hypersonic automobiles for years now, although none are operational but. (Hypersonic automobiles are good weapon-delivery programs, as a result of their maneuverability makes them harder to counteract than conventional ballistic missiles.)
“One of many areas that we’re is, how can we assist the Division of Protection in mitigating dangers for lots of their costly flight testing?” Millman mentioned. “Our testbed has the power to hold payloads. It has the power to check supplies. It has the power to fly quite a lot of profiles which can be of curiosity to people throughout the spectrum each offensively and defensively when it comes to hypersonics.”
