Boom Supersonic’s XB-1: 1st Civil Aircraft To Go Supersonic In U.S. History

January 29th, 2025

Via: Live Science:

Boom Supersonic’s XB-1 has successfully broken the sound barrier, becoming the first supersonic civil aircraft in U.S. history.

Today (Jan. 28), the XB-1 took off from Mojave Air and Space Port in California and reached Mach 1.1 — equivalent to 1.1 times the speed of sound, or 844 mph (1,358 km/h). It reached this record speed on three separate occasions during its 34-minute test flight.

Boom Supersonic is now the first independent company to break the sound barrier with an aircraft intended for civilian use. (The Concorde was created in agreement with the U.K. and French governments, while the Tupolev Tu-44 was designed and manufactured with support from the Soviet government.)
