Can't see it happen unless, in the future, they find an extremely cheap source of fuel and durable construction materials. Actually, I'm not entirely sure that fuel would be the show stopper here. I think that the best concept for a supersonic jet would be a combination of turbojets and ramjets, much like the SR-71 had. Ramjets come with the beautiful little detail that they get more efficient the faster you fly, because the pressure ratio increases with speed. What's been the showstopper for supersonic jets so far has mainly been the sonic boom, so that routes (or at least their supersonic parts) are limited to the oceans. This leaves only transatlantic, transpacific and some south-east asian routes. If any company could come up with an airplane that had the range for those routes, it might even end up selling fairly well, because you could demand quite the premium for a ticket that gets you to your destination in half the time. What's most prohibitive is probably the risk, coupled with the development costs.

I'd say from a market demand perspective anything with transpacific range will find it's passengers. Those flights take so long. Just think of all those ultra-rich IT-guys going back and forth all the time.

Just think of all those ultra-rich IT-guys going back and forth all the time. And this is one reason the next long-range supersonic aircraft might be a business jet. I remember Dassault started a project a few years ago, even trying in vain to get the French Air Force to pay for development of a suitable engine ...

Maximum speed of only Mach 1.5... Still, this news probably brings the programme closer to reality than any other post-concorde supersonic civil aircraft projects. Hope it goes all the way.

Their point is some advanced laminar flow wing. Sounds like they maybe even fly in supercruise without burners to get the required range.

Concorde I believe could super cruise with out the use of ABs (After Burners). The ABs were used for take off and climb to get as high as possible as quick as possible. If it needed ABs for sustained supersonic flight it would have ran out of fuel over the Atlantic ?

This, to me, was one of the most remarkable bits of engineering that went into the Concorde, especially given its size and weight. It was capable of supercruising without the use of fuel thirsty ABs at Mach 2.00. Fighter aircraft are generally limited to much less than this, although the 5th generation F-22 can do up to 1.8 for short periods.

The F22 could not even do the Atlantic with one PAX at super cruise without a tanker top up ! Concord (uk spelling), it could have done UK to Australia with a few top ups
