Boom Supersonic, based in Colorado, is currently developing the world’s first supersonic passenger aircraft since the retirement of Concorde over two decades ago. The company recently achieved a milestone in the project when its small-scale test aircraft, the XB-1, successfully broke the sound barrier. The aircraft is made primarily from lightweight carbon fibre and utilizes an augmented reality vision system to aid in landing. Boom’s Overture airliner aims to be the first supersonic passenger aircraft in more than 20 years, and the company believes that it can achieve sustainable commercial supersonic flight.
In the 1950s, the aviation industry was enthusiastic about supersonic air travel, following Chuck Yeager’s achievement in breaking the sound barrier. Major manufacturers like Boeing and Lockheed began developing supersonic passenger aircraft, including the Boeing 2707 SST and the Lockheed L-2000. However, neither aircraft entered production. The only supersonic passenger planes to ever enter service were the Russian Tupolev Tu-144 and the Anglo-French Concorde. Concorde, in particular, faced challenges related to noise, fuel consumption, and high operational costs, which ultimately led to its retirement in 2003.
Concorde’s issues with noise, sonic booms, and high fuel consumption contributed to its downfall. The aircraft was forced to operate at subsonic speeds over land due to complaints from communities below its flight path. This limited its potential routes and passenger appeal. Furthermore, the aircraft’s operational costs were high, resulting in exorbitant ticket prices. The fatal crash of an Air France Concorde in 2000 further highlighted safety concerns and maintenance costs, ultimately leading to the retirement of the Concorde fleet.
Boom Supersonic aims to address the challenges that plagued Concorde, notably noise, cost, and efficiency. The company’s Overture airliner will not use afterburners, reducing both fuel consumption and noise levels. Advanced soundproofing measures will enhance passenger comfort, and the use of sustainable aviation fuel will further reduce environmental impact. While the sonic boom effect will not be eliminated completely, the company promises a significant reduction in its impact. Overture is expected to be able to fly over land at Mach 0.94 without breaking the sound barrier, offering a faster option for transoceanic routes.
Boom is targeting a niche market of business travellers with its more affordable ticket pricing compared to Concorde’s ultra-luxury fares. The company has received orders for 130 Overture aircraft from global airlines, with an entry into service planned for 2029. By addressing the issues that led to Concorde’s retirement, Boom Supersonic aims to bring mainstream supersonic travel back into the aviation industry. With advancements in technology and market demand for faster air travel, the company believes that the time is right for the reintroduction of supersonic passenger flights.
