The preliminary design review was originally planned to be completed by June 2017. [5] While NASA received three inquiries for its August 2017 request for proposals, Lockheed was the sole bidder. [6] On April 2, 2018, NASA awarded Lockheed Martin a $247.5 million contract to design, build and deliver in late 2021 the Low-Boom X-plane.
The Boom XB-1 "Baby Boom" is a one-third-scale trijet supersonic demonstrator designed by Boom Technology as part of the development of the Boom Overture supersonic transport airliner. Powered by three General Electric J85 engines, [ 2 ] it is designed to maintain a speed of Mach 2.2, with over 1,000 nautical miles (1,900 km; 1,200 mi) of range.
Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).
The X-59 is the latest in a series of experimental planes which include the X-1, which in 1947 became the first manned aircraft to exceed the speed of sound, and the X-15, which still holds the ...

Manned by Boom Supersonic's chief test pilot Tristan "Geppetto" Brandenburg, the XB-1 launched in the early hours of Tuesday, reaching an altitude of 35,290 feet and accelerating to speed Mach 1. ...
The Douglas D-558-2 Skyrocket (or D-558-II) is a rocket and jet-powered research supersonic aircraft built by the Douglas Aircraft Company for the United States Navy.On 20 November 1953, shortly before the (17 December) 50th anniversary of powered flight, Scott Crossfield piloted the Skyrocket to Mach 2, or more than 1,290 mph (2076 km/h), the first time an aircraft had exceeded twice the ...
One unique aspect of supersonic flight has nothing to do with speed, but instead altitude. Up around 50,000 feet, Drake said he could see the curvature of the earth.
