Boom Supersonic, the aerospace innovator behind the future’s fastest passenger aircraft, Overture, made headlines with the successful maiden flight of XB-1, the first supersonic jet developed independently, at the Mojave Air & Space Port in California. The XB-1, a testament to cutting-edge advancements, incorporates revolutionary materials and technology, such as carbon fiber composites and sophisticated avionics, to achieve efficient supersonic travel. It also features digitally refined aerodynamics and a leading-edge supersonic propulsion system.

“Today, XB-1 took flight in the same hallowed airspace where the Bell X-1 first broke the sound barrier in 1947,” said Blake Scholl, founder and CEO of Boom Supersonic. “I’ve been looking forward to this flight since founding Boom in 2014, and it marks the most significant milestone yet on our path to bring supersonic travel to passengers worldwide.” 

The XB-1’s inaugural flight was piloted by Boom’s Chief Test Pilot, Bill “Doc” Shoemaker, with Test Pilot Tristan “Geppetto” Brandenburg flying the T-38 chase plane for observation. Launching from Mojave Air & Space Port, the XB-1 soared through airspace that has witnessed numerous groundbreaking flights, such as those by the Bell X-1 and the SR-71 Blackbird, meeting all its test goals. It reached an altitude of 7,120 feet and speeds of up to 238 knots (273 mph).

“Everyone on the XB-1 team should be incredibly proud of this achievement,” said Bill “Doc” Shoemaker, Chief Test Pilot for Boom Supersonic. “It has been a privilege to share this journey with so many dedicated and talented professionals. The experience we have gained in reaching this milestone will be invaluable to Boom’s revival of supersonic travel.” 

This event marks a significant milestone nearly twenty years following the Concorde’s retirement, heralding the resurgence of commercial supersonic flight. The XB-1 project not only lays the groundwork for Overture’s development but also emphasizes a commitment to safety and innovation in aerospace engineering and manufacturing. The XB-1 has validated several pioneering technologies:

• An augmented reality vision system, employing two forward-facing cameras enhanced with flight data to feed into a high-resolution display for the pilot, ensuring superior visibility and streamlining aerodynamics without the need for a bulky, movable nose.
• State-of-the-art aerodynamic modeling, with engineers leveraging computational fluid dynamics to refine thousands of design iterations, culminating in an aerodynamically optimized structure that maintains stability and efficiency across various speeds.
• The extensive use of carbon fiber composites, enabling the XB-1 to embody a complex aerodynamic shape in a durable yet lightweight framework.
• Advanced supersonic intakes designed to decelerate air from supersonic to subsonic speeds, effectively transforming kinetic energy into pressure energy, facilitating the use of conventional jet engines from takeoff to supersonic velocities.

As the XB-1 takes to the skies, the Overture project moves closer to fruition, supported by a global consortium of leading suppliers and a robust order book from major airlines, including American Airlines, United Airlines, and Japan Airlines. Overture aims to transport 64-80 passengers at speeds of Mach 1.7, doubling the velocity of current airliners, with a design focused on speed, safety, and eco-friendliness, capable of operating on 100% sustainable aviation fuel (SAF).
