Boom XB-1
The Boom XB-1 "Baby Boom" is a retired 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, it was initially designed to maintain a speed of Mach 2.2, with over 1,000 nautical miles (1,900 km; 1,200 mi) of range; but the demonstrator was tested to only Mach 1.1 and no long–range flights were made.
