The Lockheed Martin X-59 QueSST (“Quiet Supersonic Transport”) is an American experimental supersonic aircraft being developed for NASA’s Low-Boom Flight Demonstrator program. Preliminary design started in February 2016, with the X-59 scheduled for delivery in late 2021 for flight tests from 2022. It is expected to cruise at Mach 1.42 (1,510 km/h) and 55,000 ft (16,800 m), creating a low 75 Perceived Level decibel (PLdB) thump to evaluate supersonic transport acceptability.
