Boom Supersonic's Overture Aims to Revive Commercial Supersonic Travel with 2029 Service Target
Why It MattersA successful Overture program would reopen a supersonic passenger segment dormant since Concorde's 2003 retirement, testing whether clean-sheet airframe and engine certification can be achieved simultaneously.
Boom Supersonic is developing the Overture airliner to carry 64 to 80 passengers at a cruise speed of Mach 1.7, roughly 1,300 miles per hour, in a single premium cabin designed to run on up to 100 percent sustainable aviation fuel. The company's one-third-scale demonstrator, XB-1, broke the sound barrier over the Mojave Desert on January 28, 2025, reaching Mach 1.122, becoming the first independently developed supersonic aircraft to do so.
Boom targets 2029 for the start of commercial service, with first flight of the full-scale Overture planned for 2027, though independent analysts expect the timeline could slip into the early 2030s. The program's biggest technical risk is the simultaneous certification of a clean-sheet airframe and Boom's own Symphony medium-bypass turbofan engine, developed after no established engine manufacturer agreed to build one; Symphony is designed to sustain supersonic cruise without afterburners. Boom has also demonstrated boomless supersonic flight using Mach cutoff, in which shockwaves refract through atmospheric layers and dissipate before reaching the ground, potentially reopening overland supersonic routes closed since the 1970s. Overture is designed to cruise at approximately 60,000 feet and uses external camera-based vision systems in place of Concorde's mechanically drooping nose.
American Airlines has placed a conditional order for 20 aircraft, United Airlines for 15, and Japan Airlines has also signed on, with combined orders and options totaling up to 130 aircraft; Delta Air Lines has publicly declined, with CEO Ed Bastian stating in 2022 he had more questions than answers, and at least one previously linked airline has since withdrawn. Boom's projected routes are concentrated on oceanic corridors, including New York to London in approximately 3.5 hours versus today's roughly 6.5 hours, Tokyo to Seattle in 4.5 hours versus 8.5 hours, and Los Angeles to Sydney in 8.5 hours versus 14.5 hours, with the company saying Overture could eventually serve more than 600 profitable routes worldwide. Ticket pricing has not been published, though Boom has stated it is targeting business-class-range fares rather than Concorde-era luxury pricing. Commercial supersonic flight has not operated since Concorde's retirement in 2003; only Concorde, jointly operated by British Airways and Air France from January 1976 to 2003, and the Soviet-built Tupolev Tu-144 have ever carried passengers supersonically.
