HyperMach’s planned 20-seat supersonic business jet (SSBJ)–SonicStar–will be able to fly at speeds up to Mach 4.0.
HyperMach said it is increasing the top speed of its planned supersonic business jet from Mach 3.6 to Mach 4, which would allow the aircraft to fly from New York to Dubai in only 2 hours 20 minutes. The jet won’t enter service until at least 2025.
