The US has ended its 52-year ban on supersonic flights over land through an executive order by President Trump, supporting the revival of high-speed aviation and benefiting companies like Boom Supersonic, though technical, financial, and commercial challenges remain.
Venus Aerospace is developing a hypersonic aircraft called Stargazer that can carry about a dozen passengers and travel at Mach 9, or 6,905 mph, at an altitude of 170,000 feet. The aircraft will use a rotating-detonation engine that burns 20% less fuel than a conventional engine and has been successfully tested using a room-temperature storable propellant. The Stargazer will take off with conventional jet engines and transition to rockets once it reaches altitude. The company hopes to begin hypersonic flight testing with a 20-foot drone that will reach Mach 5 before building the Stargazer prototype. Other firms, including Sierra Space and Hermeus, are also pursuing hypersonic aircraft concepts.
