Boom XB-1

When fully operational, the Starship launch system is expected to dramatically lower the cost of access to space through its tremendous economies of scale and is a crucial component of the company's goal of reaching Mars, so this first successful test marked a major milestone in the process of unlocking the next era of space access and exploration.

On March twenty-second, Boom Supersonic conducted the first successful test flight of their XB-1 demonstrator aircraft, which they say will be, quote, "the world's first independently developed supersonic jet." It reached a top speed of two hundred and seventy-three miles or four hundred and thirty-nine kilometers per hour in twelve quick minutes of flight.

This was just the first of a number of test flights the company conducted this year at the Mojave Air and Space Port, and March's flight was the first instance of a non-military supersonic aircraft flying in US airspace in twenty years, last done by Concorde, even if it didn't yet reach supersonic speeds.

Developing and successfully flying this single-seat jet is a crucial step in Boom's goal of introducing its eighty-seat commercial supersonic aircraft, Overture, to the skies by twenty twenty-nine.

Where does Boom Supersonic stand with the Overture airliner? Boom Supersonic holds thirty-five firm orders and ninety-five options for Overture and has no FAA type certificate.

Its XB-1 demonstrator, a tri-jet with three General Electric J85-15 engines and a maximum takeoff weight of thirteen thousand five hundred pounds, first flew on March twenty-two, two thousand and twenty-four and reached Mach one point one two two on January twenty-eight, two thousand and twenty-five.

The final planned test flight on February ten, two thousand and twenty-five demonstrated Mach cutoff operation under a special flight authorization.

XB-1 is a different aircraft from Overture, and its results do not certify the airliner.

Overture is specified at Mach one point seven cruise, sixty thousand feet, four thousand two hundred and fifty nautical miles of range, sixty-four to eighty passengers, and a maximum takeoff weight of four hundred and fifteen thousand pounds, powered by four Boom Symphony medium bypass turbofans.

Disclosures place Symphony thrust between thirty-five thousand and forty thousand pounds per engine.

Hermeus pursues defense demand, and NASA community response data will inform both the FAA and ICAO.

If the FAA finalizes the zero point one one PSF standard by June sixth, two thousand and twenty-seven and later issues a Part thirty-six landing and takeoff standard, overland routes such as New York to Los Angeles would open to aircraft that meet both.

Boom Supersonic, whose turbines they were buying, is a company whose entire reason to exist is building a supersonic airliner.

Their demonstrator jet, the XB-1, actually broke the sound barrier for the first time in early 2025, the first civil supersonic flight over the continental U.S., So the same turbine tech that came out of chasing supersonic passenger flight was about to power an AI data center in Texas.

That's a genuinely strange supply chain.

That is a beautiful piece of trivia.

The small team with a big dream.

In 2025, XB-1 became the first privately developed jet to break the sound barrier.

You are go for Mach 1.1.

But this time, we demonstrated that supersonic flight could be boomless.

Thank you.

Uh, I thought that would get old, but it never does.

Uh, XB-1 uses actually a far simpler technique than others have talked about to solve sonic boom.

We call it boomless cruise, and it uses the natural refractive power of the atmosphere to redirect the sonic boom upwards.

So, yep, three and a half hours.

So, Boom's XB-1 demonstrator has already taken shape and proven that aerodynamic principles behind overture aren't theory.

And unlike the Concorde, Boom is committing to 100% sustainable aviation fuel, trying to solve...

The environmental criticism that helped ground the Concorde.
