While the technology previously existed and NASA has already been testing a preliminary design called the Quiet Supersonic Transport, or QueSST, the U.S. government’s recently approved 2019 budget includes full funding for the experimental plane. "This budget maintains a robust investment of $633.9 million to improve air traffic management, make progress integrating unmanned systems into the airspace, and fund an experimental supersonic airplane and increase hypersonics research," NASA Acting Administrator Robert Lightfoot said during the annual State of NASA speech on Monday (Feb. 12).

The project “would open a new market for U.S. companies to build faster commercial airliners, creating jobs and cutting cross-country flight times in half,” according to the White House Budget, which also increases funding for “research on flight at speeds more than five times the speed of sound, commonly referred to as hypersonics,” used for spacecrafts and national defense applications.
A new plane that would fly from London to New York City in three hours has just received crucial funding. The aircraft, officially named Quiet Supersonic Transport (QueSST) and dubbed the "Son of Concorde", was proposed by NASA and has just been given the go-ahead by US officials. QueSST could make its maiden voyage in 2021 if all goes according to plan. If so, it will halve the current travel time between London and New York City.
