Boom Supersonic Announces Key Engine Updates

Boom Supersonic has announced that it has selected a space at the Colorado Air and Space Port in Watkins to support engine testing.

The engine tests, which will be located in Watkins, are essential for its Symphony propulsion systems, which plays a role in the construction of its Overture.

Boom Supersonic highlights that this site was previously utilised for hypersonic engine development and now will play a role in helping supersonic air travel return to the aviation industry.

The company will invest USD 3 to 5 million to prepare for supersonic engine testing, with a commencement date scheduled for later this year.

In the press release, Boom states that the facility it has selected is just 35 miles from its headquarters, allowing the company to establish a strong presence and rapidly evaluate findings.

Supporting the development of the engine is crucial for the long-term prospects of Boom Supersonic’s full-scale Overture entering the skies.

Boom says that it’s rapidly advancing the concept of Symphony and bringing it to reality with the first independently owned supersonic engine test facility, all for less than the cost of renting a government-provided facility.

Additionally, by vertically integrating the population, Boom Supersonic believes that overall development of this engine will accelerate, while costs will be reduced.

While crucial tests for the engine are scheduled to begin in late 2025, significant expansion efforts are also expected to be undertaken at the facility in 2026, as full-scale testing of the entire Symphony turbofan prototype is set to commence.

The Boom Supersonic Overture

Boom Supersonic’s Overture is the full-scale aircraft the company aims to release, which airlines are expected to adopt commercially and will mark the return of supersonic travel for the first time since Concorde.

Thanks to 100% sustainable aviation fuel (SAF), it aims to cruise at Mach 1.7, carrying 65–80 passengers over transoceanic routes while maintaining net-zero carbon emissions.

Boom Supersonic remains ambitious about its goals for this aircraft, but it also experiences significant scepticism about funding, the business case, and eventual adoption.

Despite this, the company believes that Overture will serve markets for decades and help redefine premium locations, offering faster leisure and business travel.
