The XB-1 "Baby Boom" is 68 feet (21 m) long with a 17 ft (5.2 m) wingspan and a 13,500-pound (6,100 kg) maximum take-off weight. Powered by three General Electric J85 engines with variable geometry inlets and exhaust, the prototype should be able to sustain Mach 2.2 with more than 1,000 nmi (1,900 km; 1,200 mi) of range.

XB-1’s engine intakes slow supersonic air to subsonic speeds, efficiently converting kinetic energy into pressure energy, allowing conventional jet engines to power XB-1 from takeoff through supersonic flight.

2025年1月28日 · The successful first supersonic flight of Boom’s demonstrator aircraft, XB-1, took place on January 28 2025 at the Mojave Air & Space Port in California. Boom designed, built, and flew the world’s first independently developed supersonic jet—the first civil supersonic jet …

2025年3月3日 · Before today's sound barrier-breaking flight, the XB-1 underwent 11 test flights. The aircraft includes features like an augmented reality system to make takeoff and landing easier and has a...

2025年1月28日 · Boom Supersonic's XB-1 made history on Tuesday by becoming the first civil aircraft to break the sound barrier. Before Tuesday, no civil private manufacturer had passed the sound barrier with...

2025年2月11日 · The XB-1 is a one-third-sized proof-of-concept meant to demonstrate the aerodynamics involved in Overture, the company’s proposed commercial supersonic jet.

2025年1月29日 · Having demonstrated the technology with the XB-1, Boom plans to reintroduce commercial supersonic flight with its Overture aircraft, capable of carrying 64 to 80 passengers at Mach 1.7 – approximately twice the speed of today's subsonic airliners.

2025年2月8日 · Boom Supersonic's XB-1 prototype jet has achieved supersonic flight, marking a significant milestone toward developing commercial aircraft that fly twice as fast as today's airliners.

2025年3月3日 · NASA teams also collected data on XB-1’s acoustic signature at one location on the flight route. Boom analysis found that no audible sonic boom reached the ground as the jet flew at supersonic speeds. “This image makes the invisible visible—the first American made civil supersonic jet breaking the sound barrier.

2025年3月10日 · — Boom Supersonic's XB-1 jet breaks sound barrier 3 times on final test flight (video, photos) — NASA's new supersonic X-59 jet hits the afterburner (photos) The Feb. 10 test flight was the ...
