An aerospace company called Hermeus on Thursday announced a contract with the US Air Force and the Presidential and Executive Airlift Directorate to develop a hypersonic aircraft for the presidential fleet.
While the next Air Force One, a modified 747-8, is due to be delivered by Boeing next year, the Hermeus contract looks toward its eventual replacement.
Hermeus said it won the contract after designing, building, and successfully testing a prototype of an engine capable of propelling an airplane to Mach 5, or five times the speed of sound — about 3,300 mph. Mach 5 represents the delineation between supersonic and hypersonic speeds.
The company completed those tests in March, Aviation Week reported.
Hermeus plans to build a demonstrator vehicle over the next five years, with commercial aircraft envisioned in about a decade, Skyler Shuford, its cofounder and chief operating officer, said in 2019. A press release announcing the Air Force contract said part of the project would focus on integrating Air Force requirements into the airplane's designs.
I suspect it will be prototyped as Air Force Two...maybe Three...
