    ppp :

    Thats BS, there’s no reason to believe French AESA modules will be better, let alone being huge leaps ahead of those on Typhoon/F35/F22.

    Nobody talked about huge leaps ahead but you .
    Thalès people are very clever chaps and I have no doubt that their technology on Aesa modules is the very best in Europe .
    Some of their papers are showing very bright ideas and a real know-how , like this one :

    Nicolas10 :

    Or bluewings a confirmé :
    – pas de GMTI/T
    – Pas de détection de cible terrestres et de cibles aériennes simultanément sinon la possibilité de traquer une cible désignée par un autre capteur que le radar.

    – The radar detects and track the fast moving ground targets but the link (the software) in between the radar and the HUDs hasn ‘t been written yet . Basically , no firing solution against this type of target is offered to the pilot yet .
    – of course the radar can track terrestrial and aerial targets at the same time , or as I should say , almost simultaneously . Since the Pesa only use one beam , the radar has to “switch” in between targets every milliseconds when an Aesa can use multiple beams at the same time to keep a constant “eye” on multiple targets .

    Cheers .

    After asking for help for the Nth time to my friend , MK2-5 pilot here in Dijon , he told me that what want the UAE is crystal clear :

    – actually , the RBE2 (Pesa OR Aesa) is not capable to provide “velocity vectors” on moving ground targets (or fast moving boats) to the fire control system (to be able to put a weapon on it) because the logiciel (software code) hasn ‘t been written yet . So , GMTT/GMTI is only a matter of time and not a hardware bottleneck .

    – “interlacing between A-A and A-G modes” only refers (one more time) to the software and not to the hardware ~the radar itself~ . Presently , the RBE2 (Pesa) is already capable to “detect here” for air targets and tracking some of them while ‘tracking there” for static ground targets detected by Spectra .
    My friend doesn ‘ t understand what the UAE want exactly , since the Aesa RBE2 will give even more flexibility with regards to real time simultaneous detection and tracking of air and ground targets .
    What hasn ‘t been done is the link in between the hardware and the MMI : ground moving targets can ‘t be displayed on the HUDs .
    This is a software update and not a hardware bottleneck .

    He also told me that as far as he knows , the actual onboard processing power (back end) since the F2 upgrade took place is good enough for the AdA planned path .

    When I asked him about the “look” of the RBE2-AA and when he saw the pictures posted on the Net , he told me that he didn ‘t have a clue but he wouldn ‘t be surprised if that was the real end product .
    So , I bothered him a bit more by saying that the amount of T/R modules was only 838 and he responded with a smile , saying that this is not the way to rate a radar effectiveness and power because the modules used in the Aesa RBE2 have a more efficient power/ratio than the ones used by other foreign Aesa radars . He added that the maximum range and output power of a radar is not that important when one can count on third party “global eyes” , what is important is what your radar can do to put a weapon on a target without being noticed .

    Then , the discussion went on and on , until I asked if the new radar could be used as a jammer and help (or replace) Spectra . He told me that using the best Aesa radar on Earth as a jammer would be counter productive because its is NOT its primary purpose and a dedicated jammer does not use the same hardware and “ideas” .
    It is ~for now~ better to have a dedicated system than to use a radar .
    Regarding the capability for an Aesa radar to transmit data to other aircraft through high bandwidth, it is bound to distance and angular reception . He told me that the max range for a 5KW radar was about 15 nm and the receiver had to be (obviously) within the emitting radar cone , which is not possible when you fly a CAP or SEAD mission because your mates or wingmen are rarely that much in front of you .

    Then , the discussion went on and on again and he did burst some of my bubbles regarding the radars in general . He told me that without an AWAC or ground radars to help , a fighter is basically blind and relies mostly on its electronic “ears” rather than on its own radar to know what is going on around . A radar is only good when you know where to search .
    Since everybody , from the AWACs to the ground radars , is scanning on every frequency they can think of to detect hostiles from far away , it is better to listen than to emit . You learn far more and much quicker about the adversary when you want to penetrate , then it is stealthier .

    So , what ‘ s the fuzz about Aesa radars so , I asked ?
    Because there are extremely good at multitasking and rather discrete , he said .

    When he left , I was thinking of the countless fights I had on some US forums (like StrategyPage) with some idiots …
    Some names comes to mind but I can ‘t decently name them , unfortunately 😡
    And they think that the old AN-APG serie is better than the new RBE2-AA .
    They ‘ll better look at the APG-82(V)1 , it would be a closer call …

    Cheers .

    I ‘ve been following this excellent thread from day one and some very clever things have been posted 🙂

    Wrt the total amount of T/R modules fitted on the real RBE2-AA , it is still everyone ‘s guess until a French “Méca” in the airbase ‘s shelter get us a snapshot of the real thing .

    The difference and the edge when compared to other Aesa fighters arrays lies elsewhere .
    As an example , when one wants to “calculate” the possible range of a radar , he has first to know the total output power but not all T/R modules have the same output power .;)
    Is it better to have an Aesa radar made of 1200 T/R modules rated at 8W each , or an array made of 838 (?) T/R modules rated at 20W each ? 😉

    If you do the maths , you ‘ll get just under three times more output power , which is then used accordingly with the back-end and the software in charge .
    And since the latest MMICs are less sensitive to heat , the planned cooling system is right up to the task .
    And some are talking about the old APG-80 technology .:rolleyes:

    Now , the real problem lies with the output power generated by the aircraft : the Rafale comes a bit short but without being left behind , nonetheless . 😮
    Thalès has the best Aesa radar in Europe and the end product is as good or better than some US Aesa radars and the French software coding knowledge is highly regarded .

    But the Rafale ‘s primary shortcoming (who maybe was unseen from the original blueprints and not given enough thinking after a while) is its total electric output power .
    It needs more but a total re-design is desired .
    As Dassault said , maybe a -9 Rafale ?
    When you know than Aesa “cheek arrays” are planned , where will they get the power from ? :confused:

    Cheers .

    We never left, there was never any joining back.

    ?? :confused: You said :

    France joined back NATO command

    which is true , so make up your mind … :rolleyes:

    Ero Senin :

    The only reason why France joined back NATO command, since France never quited the NATO organisation, is because president Sarkozy decided to do it, without any valid reason and against the country and most politician opinion.

    I beg to disagree . The reasons to join back are perfectly valid .
    He did well .

    @Mercurius

    Could you give us your personal view on that J-20 , please ?

    This is not the end product yet I believe , most probably an advanced demonstrator , just before to go to the real prototype stage . Maybe its final shape could even be slightly different .

    What are they trying to archive and for what purpose ?
    As I said before , I see a stealth long range multirole fighter .
    You ?

    Cheers .

    PParker :

    your hopes of stealth being useless is completely unfounded in reality.

    I agree with you for the time being .
    But as others have said before me , if everybody is stealthy , we ‘ll end-up in WVR everytime .

    Passive stealth is still a great advantage and to this day , it is a powerful force multiplier even against a well equipped foe . No doubt . 😎
    There are other ways to archive the stealth factor but they are more complicated ways , mostly based on electronics or on EM fields (plasma) .

    Nicolas10 :

    I said that stealth better serves in a stealth UCaV than in a multirole manned fighter

    I disagree . I think that it is wrong for two reasons :
    1) a human is superior to a machine .
    2) protect the human , not the bot .

    alfakilo :

    A weapon system like this is only needed if one has an aggressive intent. Do you think the Chinese have an aggressive intent?

    kgblue nailed it with his answer :

    the US deployed F22 and B2 in Guam, was that a aggressive or a defensive move to fly a “stealth fighter” thousands miles away home???

    I would like to come back to the first phrase :
    “”A weapon system like this is only needed if one has an aggressive intent.””

    Which is true wrt the USA+F-22 . :diablo:
    No one in the World would even dare to try to gain the air superiority over the US soil even if the USA were using F-16s only .
    The F-22 has never been needed to defend the US airspace . It has been built exclusively to archive air superiority in enemy airspace , which shows that the USA are always building stuff to go to war and not to defend the motherland .
    As far as we know , this is the only Nation is the World to act this way … Maybe with North Korea :rolleyes:

    If I was chinese , I would ask my Gov to spend even more on R&D and national defense .
    No alfakilo , the Chinese don ‘t have any aggressive intent , by that I mean that they are not going to go to war with anybody unless they are seriously threatened . The only possible adversaries are India or the USA .
    By 2025 or so , China will be unbreakable .
    They ‘ll better be or the trio India/Japan/USA (with S. Korea et Oz) could decide to attack for whatever reason backed up by the UN (Russia would not move , too much to lose . Better side-up with the Europeans) .

    So , an aircraft like the J-20 makes perfect sense and it has been planned long ago already .
    Some experts are already saying that it is going to be a “newer” Mig-31 like Interceptor , or a long range striker “a la” F-111 , etc …
    I say that the J-20 will be used as a stealth multirole fighter , with the intended capability to fight against other stealth aircraft on equal ground (?) or to run strikes against a well defended Naval Force .

    Its top speed should be around Mach 2 (or Mach 2.2 , depending on the engines and on the RAM coating quality) , its range and payload should exceed US 5th gen fighters .

    From what I know and from what I read , its RCS head-on during cruise with canards deflected by no more than 5 degrees should be rather low , lower than “discrete” 4.5 gen fighters .
    Its first operational radar should be a Chinese/Russian Pesa radar similar in capability than the early French RBE2 but with a greater range . I guess a 180km detection range against a F-16 size target .
    AtoA and AtoSea modes will be developed first .
    It will have a long range focal array based IRST and a domestic HMS .
    From chinese papers posted on some military forums , it seems that the operational J-20 could use local low power plasma generators placed on the airframe where the radar spikes are . Diagrams and translations have been provided .
    ECMs are unknown at this point .

    250 J-20s (or more) should give China a big edge in Asia .
    From the videos I ‘ve seen and from the numerous photos of the aircraft taking off or landing , the fly by wire works correctly . The different moving surfaces move as expected and the aircraft looks very stable .
    I would ‘t be surprised to see a “fly by light system (optical fibre) like the one on Rafale .

    Sensor fusion is still unknown at this time but when one look at the latest pits on display at the recent air-shows and at some photos from the Net , it is rather neat at least regarding the MMI .

    Just to say that if the program is going well and if the J-20 ends-up as it should be , it is going to be a very capable aircraft .

    Cheers .

    mabie to Amiga500 :

    how can you not accept accept the Brawler modeling conclusion that the F-35 achieves a loss:exchange ratio 400% better than its nearest competitor?

    Personally , I discard every modelling simulation wherever it comes from .
    It is 100% BS everytime because some parameters are simply wrong and some are unknown .
    Then , you can ‘t compute pilot effectiveness and tactics you are unaware of .
    Virtual “wargames” never reflect reality , never .

    We better use Joint exercises like Red Flag , Cruzex , NATO Tiger meet , etc (there are dozens of them) or real war Ops to judge how perform an aircraft and its pilot .
    The operational F-35 doesn ‘t exist yet .

    Cheers .

    With a full internal load of fuel and weapons, the F-35 is as agile as a “clean” F-16 carrying no weapons.

    To put it simply , I don ‘t believe it 😡

    So which of the two would win in a dogfight? Difficult to answer, says Beesley who states that “subsonically, the F-35 and F-22 are very much the same airplane.

    He is blatantly lying . Fortunately , no one is this World believes such nonsense 😎

    Mein GOTT B.W- Is SATAN himself Ice skating to work, has the sky falling. Me and thee actually agree on something. 😀

    Good ! It shows that you get clever by the day :D;)
    (kidding)

    P.P. Question 1 youre target is 500miles the wrongside of Bogrovias border how do you propose to get within strike range undetected (un intercepted) without being down in the weeds.

    Question 2 as per question 1 but you are a small nation without hundreds of spark varks/ growler/prowlers etc.

    May I answer !? Please , please , may I ? :p

    I’m fairly certain if the RAF had to strike those same targets again today they would go for an LGB attack from medium level.

    I hope not unless the SEAD/DEAD work has already been done or it would be very … dangerous .
    They would use cruise missiles (Storm Shadow) from stand-off range .

    Wrightwing :

    A fighter that can turn as well or better than an F-16, and point its nose better than an F-18, is certainly nothing to sneeze at.

    We ‘ll wait to see the end product for proofs .:cool:
    It depends on what the other is flying :rolleyes:
    A Flanker is more manoeuvrable than a Viper or a Superbug .
    It also has an HMS and some good IR missiles …

    Then add in the VLO and avionics(and 360deg spherical situational awareness/engagement). I don’t think one can simply take for granted that an F-35 will be easy pickings in WVR.

    True (but to be VLO is useless in dogfight) .
    Tell me again , during a “discrete strike” how many sidewinders there are in the bays ? :rolleyes:

    Cheers .
