    @Sintra
    Paint me quite skeptic there.
    If in just three years they have changed so radically idea that means that they are gooses lost in the fog.
    So, i’m more inclined to believe that those are just proof of concepts

    Merge all the new 5 gen projects made not by the usual great ones in just a thread?

    @ haavarla
    It seems me that he was asking about the higher lenght not the smaller.
    In every case each of such bnd is better at a certain phase of the engagement process: metric band is the lest affected by the stealth feature but it is not precise, so it will gave you an early warning but just a general idea where the plane really are. L/S band is still capable to get a good range and an overall good precision in the same time, while the X band is the one for targeting but would not get nothing operating alone..
    So first one discover the menace , the second one refine the search and the third one does the killing.

    It only understandable that every new plane to be designed would be a stealth one and that it would try to address the perceived shortcomings of actual designs, more specifically the proportion between the internally carried weapons and the total possible payload.
    So they would try to get 4 full proportion weapon bays, centered on A2A weapons, and more specifically a new ramjet powered missile with two lateral intakes.
    About the three preliminary designs, 23 is based on the F-35, 24 look likea XF-23/PAK-FA mix, and the 25/26 on J-20 without canards.
    So I would guess it would be an air superiority fighter with a secondary maritime strike capability, about all of the weapons would be carried inside the weapons bays.
    23 seems me hopeless, so I’ll expect a match between the other two models

    @ Y-20 Bacon.

    Question is..
    will it be as capable as the mig-35?

    It look like the MiG in some angles but it has a completely, much more conventional configuration.
    No blended wing/body, no engine pods, just the “sting” between the two engines is not sufficient to claim any possible similarity.

    Tell my with whom you go and I will know who you are.
    Joking , also I would have voted for anyone instead of Killary.

    For the rest, Emals are a tech more important for conventional carriers, allowing them to work on a standard COGAG/CODlAG plant instead of steam than to nuclears powered ones i.e. with what is still a steam based engine..
    I would try that it means that US would stick to their 100.000+ ton CVN for a long time, without trying alternative ways.

    Also because it would be a very good thing for Russia to sell more engines while they also produce them for MiG-35.

    @ Swerwe.
    To be precise 41, from 131 to 90, 60 F-35A + 15 F-35B for AMI and 15 F-35B for MMI.

    @Haavarla
    Yes, so my surprise in seeing it sold like an actual debate.

    Think the problem is more about maintenance contracts.
    Still, I repeat, no any hinth of this in the press here, both national than local.

    Frankly, there in Italy no one is talking about it at all, so I wonder if it is just some rumors running through internet and resurfacing at times.
    Given that I live less than 10 miles from where the factory is, neither in local press I found nothing about it.

    For what I know there is not any programs like Cuda, aiming at a miniature size A2A missile specifically designed for internal carrying, neither in Russia, nor in China but even in W.Europe.

    Issue it is not about an internal weapon carryng in general but about a specific weapon and the IMHO completely flawed preliminary assumtions leading to its own development.

    @hopsalot.
    You see, maybe there is a reason because for fifty years after them not any operative plane EVER sported an internal carriage for AA missiles.
    The picture i posted (someone has told that the attachments didn’t worked?) was intended to give an hint about the problems they gave, so please allow me to repost them the again and add a comment.

    [ATTACH=CONFIG]253390[/ATTACH] Problem 1: Overly complicate and heavy expulsion system.
    [ATTACH=CONFIG]253391[/ATTACH] Problem 2: there is a great discrepance between the optimal form for storage efficiency and the one for performance.

    First one can be resolved, second one is still problematic.
    While for a bomb or even a A2G missile a compromise could be found for an AA missiles it is much more complicated, being smaller and less areodinamically efficient and maneouvrable are a bane for such category of weapons.

    @ hopsalot
    Getting a procedure of infraction from European central bank for buying weapons instead of lowering our deficit imbalance?
    Thank you for your valuable contribution.

    In response to:
    Hopsalot and MSphere

    A2A missiles designed along those guidelines for internal carriage has been developed already and put on operational use : AIM-4 and AIM-26 Falcon deployed on F-102 and F-106.
    An utter disaster but they exemplify well the problem with internal carriage of such a category of weapons .

    Compared with AIM-9

    How them were carried

    The discussion there seems me finally of a good overall lvl, just don’t exceed in defending the respective positions so not to turn it back in a fight, please.

    I’m not great on technical matters so i’ll will just made some general puntualizations.

    – there is surely an issue in integrating existing weaponries, thought for external carry and so maximizing low drag over compactness on 5gen fighters weapon bays, F-35 is not the only one having that problem.
    Solution can be different, some, like foldable fins, can be made available quite fast while designing ad hoc weapons, although optimal would surely take a huge amount of time.
    Some weapon that can alleviate the problem, like the SDB already exist, and the recent exercises have found an elegant operative solution for the time being, so we can take our time.

    – about the new GaN and Photonic radars, for what I heard more than the range or the raw emitting power their main utility against 5gen lies in the increase of resolution, shifting decisively down the point where the radar’s return signal get clouded by the environmental noise for a given emission power.

    -same for missiles, actually about all of them have midcourse guidance system, so if an plane or AD radar can get a sufficient precise position of an adversary, and with the above said system you bet they will, they can just guide its own ARH missile close enough for its own sensor to work.

    This obviously doesn’t mean that we have to thrash stealth as a whole, just that the idea of spending lot of money and about all time to made a more compact but with limited range A2A missile with tha expectancy that future combat 5gen planes would happen at a much closer range than actual ones, seems me flawed from thee beginning.
