Boom Supersonic's XB-1 has achieved a major milestone in supersonic flight, and it's a game-changer for the industry.
The XB-1 successfully completed its supersonic flight test without producing a sonic boom, a feat that's been elusive for decades.
This breakthrough achievement is a result of Boom Supersonic's innovative design and testing.
The XB-1's unique design and technology allow it to fly at supersonic speeds without producing the characteristic sonic boom that typically accompanies supersonic flight.
Boom Supersonic's innovative approach is a significant step forward in making supersonic flight a reality for commercial aviation.

Boom XB-1 Achieves Supersonic Flight
Boom Supersonic's XB-1 demonstrator aircraft broke the sound barrier three times during its first supersonic flight, reaching speeds of Mach 1.12.
The test flight originated in California's Mojave Desert on January 28th.
XB-1 broke the sound barrier three times without generating an audible sonic boom, thanks to a phenomenon called Mach cutoff, where the sonic boom refracts in the atmosphere and dissipates before reaching the ground.
A unique perspective: Does Sonic Have Gravy?
Boom Supersonic CEO Blake Scholl confirmed that the flight was a success, stating "XB-1 broke the sound barrier three times during its first supersonic flight—without an audible boom."
The company plans to incorporate this technology, called Boomless Cruise, into its Overture airliner, which is designed to reach Mach 1.3 over land without an audible boom.
This innovation has the potential to reduce flight times by up to 90 minutes on U.S. coast-to-coast routes.
Boom expects to begin engine core testing for the Overture airliner by the end of 2025, which will be powered by the Symphony engine that allows the aircraft to break the sound barrier at high altitudes.

What Is Boomless Cruise?
Boomless Cruise is a game-changer in the world of supersonic flight. By flying higher before transitioning to Mach 1, the XB-1 aircraft was able to minimize the disruption of the sonic boom on the ground.
The benefits of this approach have been explored by companies like NASA, which published a paper on the topic as far back as 2016. This research aims to deliver supersonic speed without the noise.
Boom Supersonic's XB-1 flew along a path with microphones placed along its route, confirming that no sonic boom reached the ground on every transition. This is a major breakthrough in the quest for boomless supersonic flight.
Several projects, including the Lockheed Martin X-59 Quesst, are working to deliver supersonic speed without the sonic boom disruption. It's hoped that as these technologies are proven, regulators will be more inclined to allow new supersonic transports to fly at supersonic speeds.
