More than two decades after the retirement of Concorde, which defined civil supersonic flight for a generation, the aviation world may be on the verge of a new era of high-speed travel. At the center of this development is Boom Supersonic, a Denver-based aerospace technology startup developing the "Overture" supersonic aircraft. Based on current information, this aircraft could soon enter service with several US airlines.
A key impetus for this is a recent executive order by the U.S. government aimed at removing decades-old regulatory barriers that have hindered the development and operation of supersonic aircraft in the United States. United Airlines, in particular, as the first U.S. carrier with a firm order for the Overture, could benefit significantly from these developments.
Boom Supersonic and the return of supersonic travel: A vision becomes tangible
Boom Supersonic was founded in 2014 with the ambitious goal of bringing a commercially viable supersonic aircraft to market. The company's flagship aircraft, the Overture, is designed as a passenger jet capable of carrying between 64 and 80 passengers at Mach 1,7. With a cruising altitude of an astonishing 60.000 feet, the Overture strives to minimize drag and maximize fuel efficiency. A key component of Boom's development strategy was the XB-1 Baby Boom, a full-scale prototype that successfully broke the sound barrier in 2025 and completed more than ten test flights. These test flights were used to refine the design, optimize the use of lightweight composite materials, and improve noise reduction techniques.
The development of the "Overture" aims to meet strict international noise standards, particularly ICAO Chapter 14 noise standards. This is crucial to meeting the certification requirements of the U.S. Federal Aviation Administration (FAA) and ensuring the aircraft's broad operational capability. Production of the supersonic aircraft is planned in Greensboro, North Carolina, with an initial capacity of 33 jets per year, which could double if demand increases. Boom Supersonic aims to make supersonic flight safe and economically attractive by 2029 through the use of advanced aerodynamics and engine systems.
The Overture's ability to halve travel times promises a revolution for business travelers, allowing them to take day trips to destinations previously unimaginable. Imagine being able to complete transatlantic business meetings in a single day. This would not only increase efficiency but also fundamentally change the way global business is conducted.
United Airlines as a pioneer: A strategic commitment to supersonic flight
The aviation industry is eagerly awaiting the developments emerging from Boom Supersonic. One of the most significant expressions of confidence in the project came from United Airlines in June 2021. The airline became the first U.S. carrier to formally commit to the "Boom Supersonic Overture." United Airlines placed a firm order for 15 aircraft and secured purchase options for an additional 35 aircraft. This order, however, is contingent upon successful type certification and the achievement of stringent performance milestones.
United Airlines' strategic rationale for this investment lies primarily in the significant time savings offered by supersonic flight. With a cruising speed twice that of conventional models, the Overture could enable transatlantic business trips in one day. This would give United Airlines a decisive competitive advantage in key business travel markets and strengthen the airline's position in the premium segment. Travelers willing to pay a premium for speed and comfort would be the primary target audience for such services.
To ensure the smooth introduction of the "Boom Overture" into its fleet, United Airlines is investing not only in the aircraft themselves but also heavily in infrastructure improvements. This includes extending runways, implementing noise mitigation procedures at airports, and building the necessary ground handling facilities. These investments underscore United Airlines' commitment to the supersonic project and help strengthen the case for the necessary regulatory support for the "Overture."
A Presidential Executive Order paves the way: Deregulation in the service of innovation
A critical turning point for civil supersonic aviation in the United States is an executive order signed by former President Donald Trump on June 6, 2025. This order aims to remove decades-old regulatory barriers that have hampered the growth of the supersonic aviation industry in the United States. Historically, supersonic flight over land in the United States was prohibited due to the so-called "sonic boom." The new order directs the FAA to lift this ban, allowing aircraft to legally fly faster than Mach 1 over U.S. territory.
The order proposes the establishment of an interim, noise-based certification standard designed to align community tolerance levels with technological capabilities. This will replace older acoustic limits established prior to recent technological advances in noise reduction. These new standards are critical to increasing public acceptance of supersonic flight and minimizing operational limitations.
In addition, the executive order includes additional provisions directing the FAA to repeal other regulations that impede the design, development, and entry into service of supersonic aircraft. These include, but are not limited to, flight testing restrictions and hurdles to engine manufacturer certification. The order also calls for coordinated research and development in supersonic flight to be pursued by various government agencies under the direction of the National Science and Technology Council and the Office of Science and Technology Policy.
The executive order also calls for international engagement to promote the acceptance of supersonic flight worldwide. This includes encouraging the renegotiation of bilateral air service agreements that facilitate supersonic flight. This order is part of a presidential agenda emphasizing industry deregulation and aimed at accelerating technological innovation and strengthening the United States' competitiveness in key industries.
Potential impact on United Airlines: A clear path to market leadership
The recent executive order from the White House will undoubtedly have a positive impact on United Airlines, as it paves the regulatory path for the Overture to operate both domestically and internationally. The lifting of the ban on supersonic overland flight will allow United Airlines to operate the Overture on the most popular domestic routes within the United States. This could significantly reduce intercoastal flight times; for example, a New York-San Francisco connection could be reduced to approximately 2,5 hours. For business travelers commuting between the country's major metropolitan areas, this would represent a significant time savings and a critical competitive advantage.
The proposed new interim noise certification standard is also beneficial for United Airlines. It will help reduce uncertainty and resistance to supersonic flight from both local communities and airports. The elimination of additional regulations, including flight test restrictions and engine manufacturer approval hurdles, will also shorten the implementation timeline, potentially making it easier for the airline to bring the Overture into service as early as 2029.
The need for international regulatory coordination is a crucial component of United Airlines' strategy, as the airline also plans transoceanic supersonic flights. Global regulatory harmonization would allow the airline to operate its supersonic aircraft on global routes without being hampered by differing national regulations. All of these factors reduce the investment risk for United Airlines and increase the likelihood that the airline can offer supersonic flights sustainably, safely, and profitably.
United's vision: Using the Boom Overture on premium routes
United Airlines plans to position the "Boom Overture" as a premium high-speed travel offering, focusing on the most lucrative international and transcontinental routes. Initial routes currently being evaluated include services from Newark (EWR) to Frankfurt (FRA), from San Francisco (SFO) to Tokyo (NRT), and from Los Angeles (LAX) to Sydney (SYD).
The introduction of a Mach 1,7 service would drastically reduce travel times on these routes, allowing business travelers to complete round-trip day trips. On the San Francisco to Tokyo route, for example, the travel time would be reduced from the current 15-plus hours to less than XNUMX hours, allowing business travelers to attend meetings in Asia and return to the United States the same day. On the Los Angeles to Sydney route, which currently takes XNUMX-plus hours, the Overture could cut flight time by about half, significantly reducing travel time for travelers.
United Airlines intends to offer one or two daily departures on each of these supersonic routes, taking into account peak business traveler demand. The introduction of relaxed regulations for supersonic overland flight could also allow United Airlines to operate its supersonic aircraft on highly profitable transcontinental routes. For example, the New York-San Francisco route could become a 2,5-hour flight, which, considering the time difference, could result in some passengers landing before their scheduled departure time.
United Airlines' strategic vision, consistently characterized by bold thinking in the years following the pandemic, includes not only flights to more ambitious destinations but also a radical fleet expansion through the integration of new technologies. Operating supersonic flights would fundamentally change the airline's business model and the way it serves the most affluent demographic of premium travelers. This represents an incredible opportunity for the airline to generate significant revenue from these premium services. While significant hurdles remain on the path to implementing "Overture" on many of its key routes, American Airlines believes it has taken an important step toward removing these barriers with the President's recent executive order.
