Aerion is looking beyond the 2027 launch of its AS2 supersonic business jet for the ultra-rich, to something for the rest of us. The AS3TM, if it gets built, would be a 50-passenger supersonic commercial airliner capable of speeds over Mach 4.

That's at least twice the maximum speed of the venerable Concorde, and represents a ground speed somewhere over 3,000 mph (4,800 km/h). That would mean LA to Tokyo in under three hours, according to Aerion, instead of nearly 12 hours on today's airliners.

The AS3TM would have a range around 7,000 nautical miles (12,964 km, 8,055 miles). If that's a genuine, usable range figure and doesn't include mandated fuel reserves, it's enough to handle most long-haul routes outside the top 10 longest flights in the world. Aerion eventually wants to let people travel between any two points on the globe in three hours or less.

The company says this supersonic airliner "is targeted to take to the skies before the end of the decade," but the hurdles between here and your first Mach 4 plane ticket are substantial. Firstly, there's the issue of regulations, which, as we discussed with Gene Holloway, Aerion's Chief Sustainability Officer and Executive VP Environment & Sustainability last year, won't be allowing supersonic flight over land any time soon. Even transonic flight using boomless cruise technology is still up in the air.

Then there's the market. The long-term financial effects of COVID-19 on the aviation industry are still unknown, but certainly one of them is that the world as a whole is now very comfortable with doing business online instead of face to face. Will it pick back up and exceed previous levels before the end of the decade? It's hard to say.

Still, this will be a premium offering, and the fact that anyone flies first class at all demonstrates pretty clearly that there are plenty of people out there willing to pay many times the economy ticket price for a little extra comfort. We're sure there are some deranged lunatics out there that actually enjoy 12-hour flights, but for the rest of us, a supersonic option that cut it down to the length of a single movie and a trip to the bathroom might look attractive at any price.

Aerion is well-funded, with Boeing on board as an investor/partner and billionaire Robert Bass its founder. Its new office building, under construction in Melbourne, Florida, is a US$300 million facility. The AS2 business jet has already made at least US$10 billion worth of pre-sales at US$120 million a pop. So the AS3TM is certainly within the realms of possibility. We'll learn more about the aircraft later this year. Check out a video below.

We really need to work out how to make a practical Star Trek 'Beam me up Spock' transporter instead of harming the Earth via fossil fueled planes.

"Will it pick back up and exceed previous levels before the end of the decade?"

I'll give you a hint: no.

Also... safety?

There is an upside: flying at mach 4 at the edge of space is super cool. I think people would be willing to pay for the experience of becoming a pseudo astronaut, and getting from point A to B would be a happy side benefit.


@VincentWolf They ostensibly use matter-energy conversion in ST, which is would both solve a whole bunch of problems way beyond transportation and risk dooming the entire human race.

Consciousness uploading is *more* practical, but still a rather difficult problem. Using a holodeck at either end of a meeting would be easier, and I think thats where the world is headed.

Well, anything that pushes the tech forward! I hate long flights. My dad (born in 29) told me when he first flew to America from Europe it took 3 or 4 hops in a propeller plane and 3x as long, so I shouldn't complain!

So their first jet will go mach 1.4, cool, but even the Concorde could do mach 2.
Also, they have no interest in reducing the sonicboom, it's obvious that they think their ties with Boeing will get them through all that red tape.
But I wish them the best of luck, ALL air travel should be supersonic by now.

It will require a very significant breakthrough in intake technology to reach Mach 4; unless they've cracked the supersonic combustion ramjet, of course.
