The world’s first independently developed supersonic jet
Proven at Mach 1
XB-1 is the demonstrator aircraft that proved the technology behind Boom’s supersonic programs — validating the aerodynamics, materials, and systems that now carry through to Symphony and Overture.
Pressure waves
Undisturbed air
Transonic
Supersonic
The first civil supersonic aircraft since Concorde
Breaking the sound barrier, privately funded
XB-1 became the first independently developed aircraft to fly faster than sound, proving that a small, focused team can achieve what previously required a national program.

What XB-1 proved,
Overture will fly
From demonstrator to airliner
The aerodynamic design, materials, and systems validated on XB-1 directly inform the design of Overture, reducing technical risk on the path to commercial supersonic flight.
