Boom Supersonic’s XB-1 Demonstrator Inches Closer to Breaking the Sound Barrier
Boom Supersonic’s XB-1 demonstrator is close to breaking the sound barrier, potentially becoming the first commercial jet to do so since Concorde. In its 11th test flight, the aircraft achieved Mach 0.95 (728 mph) at a low altitude of 29,481 feet, enduring intense dynamic air pressure. The tests aim to incrementally expand speed and altitude limits, with plans to exceed Mach 1 in early 2025. The XB-1 serves as a testing platform for the Boom Overture, a supersonic passenger jet slated for the 2030s, capable of reducing transatlantic flight times to 3 hours and 30 minutes.
Boom Supersonic’s XB-1 supersonic demonstrator is on the verge of becoming the first commercial jet to break the sound barrier since Concorde. After successfully completing its 11th test flight, the aircraft achieved Mach 0.95 (728 mph or 1,172 km/h) at low altitudes, showcasing its potential to redefine air travel.
The test, conducted on January 10, took place at 29,481 feet (8,986 meters)—a lower altitude than previous flights at similar speeds. This resulted in the aircraft experiencing intense dynamic air pressure, a significant milestone in proving the durability and stability of its airframe under transonic conditions. Despite the stress, Boom confirmed that the XB-1 will face less strain during its operational flights, which will occur at higher altitudes with thinner air.
Nick Sheryka, Boom Supersonic’s chief flight test engineer, emphasized the importance of incremental progress: “The second half of our test campaign focuses on gradually increasing altitude, speed, and Mach number until we create that sonic boom.” He also highlighted the challenges of flying a piloted aircraft, contrasting it with the faster iteration cycles possible with unmanned systems.
Since its inaugural test in March 2024, the XB-1 has undergone rigorous evaluations, including testing its digital handling system and the structural integrity of its airframe under high-speed airflow. The company plans to surpass Mach 1 speeds by early 2025, barring the need for an additional 12th test flight.
The XB-1 is a precursor to the Boom Overture, a supersonic passenger jet designed to carry 64 to 80 passengers on transatlantic routes in just 3 hours and 30 minutes. Scheduled for launch in the 2030s, the Boom Overture aims to revolutionize commercial aviation much like Concorde did decades ago.
By achieving these milestones, Boom Supersonic is paving the way for a new era of faster, more efficient air travel.
Disclaimer
The XB-1’s development represents significant technological advancements, but testing is ongoing, and final performance is subject to further trials and regulatory approvals.
