Supersonic Comeback
In January 2025 Boom's XB-1 became the first independently developed jet to break the sound barrier; the Overture airliner is planned for about 2029.
Open in the interactive tree →Concorde flew from 1976 to 2003 and was retired because of cost, noise (sonic boom) and the 2000 accident. New designs rely on more efficient engines, composites and computational aerodynamics. Supersonic flight over land has been banned in principle in the US since 1973; relaxations are under discussion.
As of October 2026
Boom's XB-1 reached Mach 1.12 on its 12th test flight on 28 January 2025 and is regarded as the first independently developed supersonic jet. Boom plans the first flight of its Overture airliner (Mach 1.7, 60-80 passengers) for 2027 and service entry around 2029, with orders and options for 130 aircraft (United, American, JAL) - all company targets, and no type certificate exists. NASA's X-59 low-boom demonstrator has flown more than 25 test flights and is meant to give regulators data on how communities react to quieter sonic booms. A June 2025 executive order told the FAA to repeal the US ban on supersonic flight over land; the FAA published a proposed rule on 2 July 2026 (comments closed 17 August), and no final rule had been reported by late August 2026.
Open steps
- Public response data for quiet booms Medium AI leverageCollect and analyse X-59 survey and microphone data from several cities so regulators can set a sound-based limit for overland supersonic flight.
- An efficient, quiet supersonic engine Medium AI leverageBuild and certify an engine that cruises supersonic at acceptable fuel burn and airport noise; Boom's Symphony turbofan is not yet certified.
- Low-boom shape for a passenger airliner Medium AI leverageScale the shaping that makes the X-59 quiet to a 60-80 seat airliner with real payload and range.
- Climate effects at high altitude Medium AI leverageQuantify NOx, water-vapour and contrail effects at supersonic cruise altitudes and test whether sustainable fuel can offset the climate cost.
Where AI could help
Low AI leverage. Overture needs a new engine, certification and sonic-boom rules; AI can speed aerodynamic and boom-shape design, but flight tests decide.
- Design low-boom shapes by inverse design with neural networks
- Use surrogate models to optimise wing and inlet for drag and boom
- Optimise engine cycle and noise with learned models
- Analyse community response data from X-59 flights for rule-making
Shown so far
- In 2023, a deep-neural-network method for inverse design of low-boom supersonic configurations produced a ground signature consistent with the target (Advances in Aerodynamics). source
