Supersonic passenger flight, which ended in 2003 with the retirement of Concorde, is seeing renewed momentum as several new programs and regulatory changes have shifted the landscape. The return of commercial supersonic aviation gained traction after a presidential executive order on June 6, 2025, dismantled the Federal Aviation Administration’s ban on overland supersonic flight and introduced a noise-based certification standard.
This shift is significant because it removes a major barrier that had prevented viable business cases for new supersonic routes. Previously, most attractive routes were limited by regulations that forced aircraft to fly subsonically over land, diminishing their time-saving advantages. The new policy aims to support sustained investment in supersonic technology.
Boom Supersonic’s Overture program is currently one of the leading efforts in this space. In January 2025, Boom’s XB-1 demonstrator became the first independently developed civil supersonic jet built in America to break the sound barrier since Concorde. The company has an order book of 130 aircraft and a production facility capable of building up to 33 jets per year. However, industry analysts note that airline commitments are non-binding and there remains a considerable gap between demonstrator flights and certified commercial service.
NASA is also playing a role with its X-59 program designed to address sonic boom concerns that have historically made overland routes politically challenging. Built by Lockheed Martin’s Skunk Works division, the X-59 aims to reduce sonic booms to quieter “thumps.” Its findings will help inform future FAA noise standards but do not guarantee commercial viability for all proposed routes.
Hermeus represents another frontier with ambitions for hypersonic passenger travel at speeds up to Mach 5—potentially cutting London-New York trips down to about ninety minutes—but this project remains at an early research stage without near-term plans for commercial entry.
The practical outcome of these developments may be premium-priced services aimed at business travelers on high-yield transatlantic routes such as New York-London or Boston-London rather than mass-market replacements for current widebody jets.
