    no the 2010 suits my point fine

    What the Emirians are calling for is much more complex. They want, in addition to the AESA, to have new functionalities on their Rafale, such as GMTT / GMTI detection and tracking of moving ground target, interlacing between air/air and air/ground modes, etc
    (do you know what this means ?)

    the key Emirian demand is about the range of the RBE2. And, with the same antenna diameter, the only way to achieve the 10% range increase (compared with the Basic AESA F3 “roadmap”) that wish to obtain the Emirians, is a big boost to the power of the radar.
    But more power to the RBE2, could it be a risk to generate serious electromagnetic interference (EMI) with the SPECTRA receptors ?
    There is indeed a very real EMI risk to treat. This is the case whenever we want to change aircraft emission systems. There are solutions, obviously, but this will require to reexamine SPECTRA. But the biggest problem we have identified is about electric generation, which could be insufficient. To increase the maximum range of a few nautical miles, we would have to deeply review the electrical generation system of the aircraft.
    In short, to conceive what it could be a Rafale-9, that is to say a new aircraft moving away from the similarity you want with french Rafale.
    The Emirati experts participating in negotiations are well aware of the problem. But they are also used to have very high quality weapons systems. They want to avoid any regression with the Rafale, at least on the radar range, compared to the F-16 Block 60,
    (well it looks like they cant give uae the range and he seems to acknowledge there are some other things rafale cant match on the block 60)

    you’re a giggle, so a direct quote from dassault is my invention

    “the upgrade to the active antenna simply involves replacing the tube
    transmitter and passive electronic scanning antenna with active modules”

    so are you still saying rbe2 is multibeam ? i notice you have dropped the subject, its a joke to try and compare it to the apg-79

    didnt you see, it wasnt SP, it was a french site
    http://www.airtalk.org/image-vp113192.html

    as i said according to dassault, it is simply a matter of putting an aesa antenna on the old backend
    from dassault fox three
    Designed from the outset to
    deploy an electronically scanned
    radar, the Rafale is equipped
    with the RBE2 radar from Thales.
    In production since 1997,
    the upgrade to the active antenna
    simply involves replacing the tube
    transmitter and passive electronic
    scanning antenna with active modules.

    This operation is independent
    of other functional developments
    underway. An active module is a
    transmitter/receiver based on
    solid-state technologies
    (gallium arsenide semiconductors)

    no the uae wants it to be a decent radar before they buy it. even if it doesnt do all the new fangle stuff, as the 2010 interview said

    it is what it is and needs money spent on it
    i didnt say it could do nothing good, even though it cant even do ground hugging still
    this seems to be where the yanks are at

    Interesting article from the Armed Forces Journal about Marine Corps strategy and the F-35B. The author suggests buying fewer F-35B’s and supplementing them with F/A-18F’s – noting that you can buy 3 F/A-18F’s for the cost of one F-35B – and adding new capabilities at the same time.

    http://www.afji.com/2010/07/4679496

    well he knows nothing of the internal politics of it all, does he
    the marines have point blank refused the fa-18 previously for this very reason of thin end of the wedge, once they have one, they will have many
    they dont want it and want the f-35

    it may be my settings ?
    ok,israel gets about 10%? of its defense funds in aid from usa, if israel uses their aid to buy f-35, its true
    if they use their aid for other purchases, and pay for the f-35 out of their defense funds, its wrong,
    the point of the story is that the aid and cost of 20 f-35 are about the same
    they can buy f-15/16 or whatever if they want

    As for what specific modes are and are not available, I think the internal technical info is only available to Thales and the various governments who are purchasing the Rafale. We really don’t know without access to internal documents. Frequency hopping is standard in modern radars, however, and I doubt that the RBE2 is any different. I don’t think beamforming with more than 1 beam is particularly difficult either and I wouldn’t be surprised in the slightest to see such modes on the RBE-2.

    well they havent and there are no plans to
    they simply stuck an aesa antenna on the old rbe2 backend and tidied it up a bit

    yes i changed my mind and gave a french source
    this has all been done before, its easier just to quote a french site
    http://www.airtalk.org/image-vp113192.html
    However, Dassault and Thales are not proposing to make the AESA the
    all-encompassing RF Cuisinart that Boeing (for example) envisages for the
    Super Hornet, with features such as passive detection, multi-beam operation
    and jamming. Nor does the team intend to exploit the AESA’s wide bandwidth,
    which would mean a new radome. (This suggests that the current radome is a
    bandpass design, transparent at the RBE2 frequency but stealthily reflective
    at any other.) Rather, the approach is to minimise cost and risk by keeping
    the same modes as the RBE2, while harvesting what are seen as the most
    valuable advantages of the AESA. These include a 50 per cent-plus increase
    in detection range – a better match for Meteor – much better performance at
    the edges of the elevation and bearing envelope, better reliability through
    the elimination of single-point failures and lower through-life costs.
    With only 120 aircraft planned by 2012, the pace of the Rafale programme has
    been influenced more by budget considerations than by technology. Aside from
    Singapore, Greece and possibly Saudi Arabia, there are – for the moment –
    few potential export customers for the fighter, and nothing except some
    unexpected problems with JSF is likely to change that in the long term. But
    with its unique balance of high performance, heavy load and stealth, Rafale
    appears to be far ahead of most of the new generation in terms of maturity,
    and is positioned to take advantage of any new opportunities.

    since uae owns the license to the block 60 and anyone whould have to pay a premium to uae and work with them and usa, its safe to say there wont be any other countries having the block 60,

    Man, I’d like to see your sources…

    you’re not really going to say that the rbe2 is multi beam, are you ?
    do you really know that little about your favorite plane ?

    how is the 120 planes by 2012 going….. ?

    LOL the only similarity is they are both aesa

    do i really need to put up the apg-79 functions and show you what rbe2 doesnt have ?

    your link doesnt work, but israel does get aid from usa, what they buy from usa is up to them, as history shows

    australia has ordered 14
    f-35 – 2
    rafale – nil

    plus uk norway dutch have ordered test planes

    well you better go back to the source document and give the details, as the A&C has it wrong
    perhaps even the link so we can see it, last resort would be an email to gerard
    simply looking at the functions on the apg-79 shows its nothing like the rbe2
    read my post above quoting the french, it isnt even upto a f-16

    as per usual you’re http://www.w54.biz/images/smilies/horse.gif
