The world’s first independently developed supersonic jet

Designed, built, and tested in Centennial, Colorado, Boom’s supersonic technology demonstrator,  XB-1, recently moved to the Mojave Air & Space Port to continue flight preparations.

Built for speed

XB-1’s carbon composite and titanium fuselage is propelled by three General Electric J85 engines.

Aerodynamic Balance

The ogive (modified delta) wing balances low-speed performance for takeoff and landing with high-speed, supersonic flight performance.

Safety Diligence

The XB-1 team has completed hundreds of hours in the simulator for aircraft evaluation, operations development, and human factors assessments.

An Up-Close Look at XB-1

Program Advancements

Jeff Mabry, VP of XB-1, details the aircraft’s 2023 end-of-year milestones and its progress toward first flight, which is planned for early 2024.

XB-1 Taxi Testing

XB-1 has continued extensive ground testing since arriving at the Mojave Air & Space Port. Watch XB-1’s recent taxi test events.
