Soon after, in May 1961, Alan Shepard became the first American and second person to fly hypersonic when his capsule reentered the atmosphere at a speed above Mach 5 at the end of his suborbital flight over the Atlantic Ocean. [3] In November 1961, Air Force Major Robert White flew the X-15 research aircraft at speeds over Mach 6.
A Chinese aerospace firm has completed the first test flight of a passenger plane that it claims can fly at Mach 4 – more than twice the speed of Concorde.. Beijing-based Space Transportation ...
In Hermeus’s hypersonic design, a ramjet, which can only operate at high speeds as it uses this air to pressurize air and fuel in the combustion chamber, kicks in and carries the theoretical ...
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
Project Mayhem, the Air Force's secret new hypersonic bomber, is underway. Development on the bomber, which travels at Mach 10, just took a big step forward.

The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010. After two unsuccessful test flights, the X-51 completed a flight of over six minutes and reached speeds of over Mach 5 for 210 seconds on 1 May 2013 for the longest duration powered hypersonic flight.
