    you speak french, why dont you email thales ?
    sar isnt isar

    your link said its was the old rbe-2 that was tested, are you saying that has isar ?
    “The report of a flight-test of Rafale B301 in F3 standard before it has formally equipped AESA radar and Spectra EWS.”

    i’m not saying it isnt sea capable, it was in reference to isar and if we had the link to what blueapple found, it may give more info

    blueapple do you have the link to “F3 standards saw the addition of air-sea modes (including long-range ship tracking, at more than 100nm)”

    if one of you french speakers could send an email to Thales and get it clarified on the isar and ew/ea
    that will tell us what is going on

    i dont think osf-it is night/bad weather, but rafale is getting a decent IFF system
    nope, it was a guess based on the f-22 ID’ing at 180k in normal, i would have to look up and see if they give a range to an isar ID of a given radar
    i know very little about 2D isar imaging for automatic recognition within a library

    The TV channel of the the OSF make a big part of this job (with the advantage of being silent)

    at a guess, the difference is good weather, daylight 40k vs 100+k all weather, day/night
    why dont you read up on the use of isar

    Well the datasheet says SAR modes

    My humble opinion is that features will be implemented on the RBE-2AA step by step as it was the case with the pesa RBE-2.

    your humble opinion sounds fair to me and probable
    i think you are stretching with the “modes

    F414 has as much as 1/2 of the F135’s thrust, but costs 1/3rd of F135.
    In which universe that makes F135 cheaper in $/lb of thrust?

    when i went to school that doesnt make it 3 times as dear on a cost per LB thrust basis
    its about 50% dearer for a LRIP engine per LB
    the f135 is said to drop about 40% in price, that will come out to near enough the same price for 2xf414 or a f135 per Lb

    if you then factor in the rising cost of the f414’s as per your example 1/2m ea per yr, there may be a cross over point where 1 f135 will be cheaper than 2 f414 and including maintenance it should definitely have a lower life time cost

    your mistake was not saying 2035-40
    if the f-22 is irrelevant in 2020-25, where does that leave the gen 4’s ?

    yawn, the b1, b2, b52 and a few more arent in production and not exportable – hence irrelevant. Get with the program.

    Thales is well able to design a radar with isar, given the money
    the priority at this stage seems to be, to get an aesa antenna working on the rafale
    there has been no mention of any function changes

    have you read arthuro’s posts ?
    if having aesa on the canards first was the claim, there wouldnt be any disputes on it
    perhaps you can correct him when you see errors in his claims

    swerve
    they dont know what other planes have or can do
    all they know is that rafale is the best because …well just because its french

    i found out about gripen isar from a link off the br hammers site

    also india say isar too

    shouldnt we allow that the f135 has ~twice the thrust of a f414
    so to say its 3 times as expensive is misleading in 2 ways, cost per Lb of thrust and the fact that as spudman said its LRIP

    from a bad memory they were looking at a 40% price reduction on the f135 costs, down the track

    What’s your problem, Jackjack ?

    The claim that we’re ahead in Europe for fighter AESA ?

    you are going to be the first canard to have aesa, this doesnt make athuro’s claim that RBE-2 is better true

    The unproved fact that RBE-2 AESA may miss a function not necessarily required by Rafale for his maritime function ? Same for EW ? And thus the fact that Rafale fails (???) at its omnirole capability ?

    Unproved ?
    dont you accept the Thales site on their aesa either, or is it like AC and a national secret
    kovy used the term fighter and in a fighter role isar would mainly be used for target ID so i read, in its omni/strike role isar is more valuable, hence why i questioned it

    It would be strange for you not to say ISAR would increase the rafale’s maritime surface target capability, also land and air capability when it is of value.
    Thats why it is used
    This runs along the lines of other things including aesa, if rafale doesnt have it, its not needed, if rafale gets it, its fantastic and better than the ones on other planes 😀

    dam, and here i thought rafale was omnirole and also on carriers
    i can find more reasons for that, only a couple of reasons for a fighter
    arthuro if you choose the source for what ISAR is, i will be happy to explain why it is of value and why gripen and phoon are having it, as best i can

    it might be best if we let arthuro choose the ISAR source, as it will then be accepted
