Science and Technology

Two and a half times faster than the Concorde and capable of crossing the Pacific in about two hours, the hypersonic ramjet engine tested by JAXA at the Kakuda Space Center passed the combustion test at Mach 5, a milestone that brings the dream of commercial flight at 5,300 km/h closer, still expected for the 2040s.

Science and Technology

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.
