Japanese and French companies will develop a new commercial aircraft capable of flying faster than the speed of sound to succeed the disused Concorde supersonic jet, according to a press release by Japan's trade ministry.

I wish them luck, but unless its operating expenses allow the airlines to offer comparable fares to sub-sonic flights, it would likely meet the same fate as Concorde. Hopefully new materials and technologies will allow this dream to become reality. It would be wonderful.

Well somebody has to research the stuff, we cannot make sonic transports Boeing style, can we? Someone has to take the risk for laying the ground work, even the tiny pieces. The reason subsonic airplanes flourish the way they do today is because there is a GIANT infrastructure for it in terms of investment in materials and design which creates what we now know as 'proven' and 'practical' technologies.
Get it in your head: More than enough people cared for subsonic aircraft, just because few care for supersonics doesn't mean it cannot work any time soon! I am sick of this cynical pathetic stance, really. With enough money anything can happen fast (to get their money, they have to believe in your product, which means you have to have convincing data, etc).
Without risk and investment there is nothing to go on, modern subsonics have a 60 year base but we got the hang of it 30 years ago, nothing has really changed since then. I don't see the point of bashing the concept and pushing it cynically out to next century.
The meaning of life is curiosity; we were put on this planet to explore opportunities.

The biggest problem remains... Making a supersonic aircraft that doesn't produce a supersonic boom. It is a vital requirement for the next Concorde, and so far, no one knows how we can do it, if we can do it!

I understand your frustrations.
Because no government, institution, or business is willing to spend billions or trillions into supersonic research. Most people would prefer to spend only two hours on a plane from Tokyo to New York. But at what cost? Unfortunately, aeronatuical engineering has developed at the most rapid pace when there is competition and conflict (e.g. Cold War & WW2).
Barring an unusual basic research breakthroughs in energy combustion or air flow dynamics, supersonic travel will not or cannot happen in the near future.
Current environment dictates a slow pace, so Japan is now shifting gears to conduct research with the French.

Wasn't Dassault working on a supersonic bizjet with the Russians just a short while ago?
I do assume this is more bizjet-sized rather than a 100-seater project, which would make precious little sense. Probably a good idea for Dasasult to get its piece of those juicy Japanese aerospace subsidies too.

The technical issues aside, why on earth does a new supersonic aircraft have to provide seats as cheaply as subsonic aircraft? Sure, make them cheaper than Concorde's seats to generate more demand but why wouldn't First and Club travellers want to pay similar prices to get there at Mach 2? BA managed to make a profit with a handful of Concordes.

I wonder if AF and BA will buy this jet? (if it ever happens...)
Its seems AF got rid of their Concorde's quickly, giving them to musiums and breaking them up etc, but BA seem to have kept a few of theirs at some airports. I think if BA broke up one of their Concorde's at LHR or MAN, there would be public uproar...
Also, which other airlines do you think are interested in supersonic jets?
If they weren't as loud as Concorde, then I wouldn't mind putting a bet on SQ, seeing they once, briefly had a Concorde or two...

Trans-Atlantic and trans-Pacific routes would obviously be candidates. Although the boom can't be eliminated yet, its effects can be reduced. I've heard a few sonic booms from high altitude aircraft, including Concorde, and they weren't as loud as the gun that's fired in the centre of Edinburgh at 1 pm every day, or as annoying as my downstairs neighbours.

That report seems short on a couple of important points.
Firstly, why assume it is Airbus? It could just as easily be Dassault. It doesn't include any details either on proposed size for the study and could therefore be the high end bizjet market rather than airliner size.
The article is very vague on several areas. Somehow I also have my doubts about the Japanese being able to manufacture a high-thrust supersonic capable engine as they don't have the experience to the degree of the three biggest engine making nations.

I think this a ploy/method/way for France to ingratiate themselves with Japanese to pave the way for Airbus sales down the road and nothing more. Can I prove this assertion? No I cannot. However it fits the pattern of French's government's willing role as a Airbus de-facto sales agent and of their industrial policy to a tee.
If I were the Japanese government, I would insist on one condition beforehand: that any airplanes that come to existence because of this project be assembled and rolled out in Japan. Let the French firms do the sub-assemblies and fabrication. I would make this demand early in the process.
The French recently muscled Japan out of a huge nuclear fusion project. I think Japan would have some ground to stand on.

This is absolutely impossible. The sonic boom is created because the air can not get out of the way quickly enough. AFAIK the shape of the wings etc could possibly reduce the effects but never eliminate them.

There actually could be a niche market for such aircraft for business travellers who can afford to pay the premium and the time advantage over conventional transport justifies the extra expense. Flying between major financial centers (Tokyo, Paris, London, New Your, Sydney, etc.). The sonic boom is not a big issue if they are routed over oceans or sparcely populated areas, and/or fly high enough. I think it is more important to maintain the take off and landing noise comparable to conventional modern airplanes.

1) to noisy (especially during takeoff and landing, also sonic boom can be reduced with modern aerodynamics)
2) inefficient old design (a more efficient and lighter plane can be build using modern aerodynamics, materials and engine technologies)
3) very expensive to maintain due to unique and outdated technologies
4) probably too big for a niche market, at least to some locations

Quoting Cornish (Reply 22): too big a terrorist target amongst other things. If loads of people bought this potential plane and it became the norm rather than exclusive like Concorde then it would be less of a target.
Understood, but I think I was trying to say is why didn't Concorde become the norm if the restriction of it flying over the oceans was acceptable (which Katekebo was saying in his original message).
Point taken though - a much more efficient version might do better, but I think they would have to do something about the sonic boom. And what about the design of the wings - it would have to be more efficient at landing speeds as well as up there travelling at mach 5 so they can reduce the noise near airports. Will be interesting to see what they come up with.
