Stratolaunch has started construction on a prototype hypersonic vehicle designed to launch from the world’s biggest airplane.

Recent pictures the company shared on Twitter show a prelude of the sleek Stratolaunch Talon-A reusable hypersonic vehicle coming together in a manufacturing facility.

“The upper skin layup tool and prototype upper skin are giving us a peek at what’s to come. One. Step. Closer,” Stratolaunch said on Twitter Oct. 20. In a separate missive, Stratolaunch thanked their employees for the ongoing hard work. “Maybe we’re biased, but we think we have some of the coolest jobs on the planet … and beyond,” the company tweeted Oct. 22.

The construction is a promising start after months of uncertainty for Stratolaunch, the future of which came into question after founder Paul Allen (also co-founder of Microsoft) died in October 2018 and the company was sold a year later

In March 2020, however, Stratolaunch announced it would pivot its services to building, testing and operating hypersonic vehicles: vehicles that fly at Mach 5, or five times faster than the speed of sound.

“Our hypersonic testbeds will serve as a catalyst in sparking a renaissance in hypersonic technologies for our government, the commercial sector and academia,” Stratolaunch CEO W. Jean Floyd said in a statement on the company website.

Stratolaunch’s Talon-A will be 28 feet (8.5 meters) long with a mass of 6,000 lbs. (2,700 kilograms) and will fly as fast as Mach 6, the company has said. Key components for the plane appear to be well under way, too.

In late October, Stratolaunch said testing on its first engine was complete, courtesy of a partnership agreement with propulsion company Ursa Major Tech. You can see a two-minute video of an engine test here

Stratolaunch also signed an agreement with Draper, a decades-old engineering nonprofit, last month to provide guidance, navigation and control software for the hypersonic vehicle. 

“Under the multi-year contract, Draper will design, develop and deliver a guidance, navigation and control system for the Stratolaunch reusable hypersonic vehicle,” Draper representatives wrote in a statement. “The vehicle is designed for use by government, the Department of Defense, the commercial sector and academia, which will contract for payload capacity for space or Earth applications.”
