History’s first independently developed supersonic jet

XB-1 is paving the way for mainstream supersonic travel by demonstrating the key technologies for safe and efficient high-speed flight.

Program milestones

Major assembly events mark key completed milestones along the path to supersonic flight. Each complete initiative serves to mitigate risk and maximize overall safety of the XB-1 program.

2023 – Flight testing begins

2021-2022 – Systems Integration & Engine Runs

XB-1 completes key test points, culminating in its first low speed taxi.


10.2020 – Rollout

XB-1 is fully assembled and revealed to the world for the first time.

09.2020 – Weight on wheels

XB-1 stands on its own for the first time, with the full weight of the aircraft on wheels.


8.2020 – Engines and inlets installed

Three J85-15 engines and supersonic inlets are installed to the aft fuselage.

08.2020 – Aft fuselage install

The fully titanium aft is joined to the forward fuselage.


07.2020 – Nose landing gear passed drop tests

The nose landing gear passed a series of drop tests at incrementally higher energy limits, validating this component’s performance up to an extreme 184 kts (212 mph) landing.


06.2020 – Forward fuselage closeout

The final significant bonding operation, closing of the forward fuselage, is complete.


03.2020 – Wing testing

A simulation of the most extreme flight conditions validated the wing design and approved the structure safe for flight.


03.2020 – Lefthand fuselage skin install

As the single largest-scale bond event, the left hand skin install completely closed the fuselage structure and set the final shape of the aircraft.

02.2020 – First flight of second-generation simulator

Assembly of the second-generation simulator enabled teams to finalize aircraft flight control design and enhance the pilot training program.


01.2020 – Wing closeout

The wing structure transformed from a skeleton frame to a completely closed unit, during this eight-hour bond event.


12.2019 – Nose landing gear and cockpit bond

This twenty hour bond event joined the nose landing gear bay and cockpit together, sealing the structure into the right hand fuselage skin.
