    F414 is for F-18E. when you create RM12 based on F414 than comparision can be made.

    The F414G exists and flying! approx 50kg more. The biggest difference from RM12 is the fansize which is 3 inch wider.

    Ge has delivered 2 engines to date for the project. They, with other suppliers are in the project, just as much as saab(taking risk and in the technology transfers), and dont get any money from it until she sells.

    On paper? Everything needs a couple of blueprints, wouldnt you say?
    The Gripen NG has been on paper only for a few months, and is up and flying already!
    Look at the competion see how fast things is rolling. See how much money the competion is burning in the process.
    Using “COTS” makes it cheaper, hitech and wellproven.

    How long has SU-35 been “on paper”? for more than a decade? is it operational?
    EF started up on paper nearly “on par” with Gripen A/B, is it still fully operational? (weapons wise)

    On the IR-signature part, I wonder if you ever calibrated you instruments…if not, do that.

    star 49, please get the facts, not your “willing to be”.

    Surely Saab can provide $20 to $25B of offsets in current environment. Even Boeing/EADS would find it nearly impossible for that kind of investmeent. SAAB does not own all intellectual rights of Gripen components. Weapons are another issue. SAAB has to demonstrate real fighter with 6 to 7 tons weopons load not some paper specification.

    Saab isn’t the provider Investor is(biggest owner). One of the biggest investment companies in the world.

    6-7 tons, is that in the recuirements? do you distrust that SAAB can deliver what they offer? have they ever not delivered? :confused:

    intellectual rights isnt a problem, Saab has contracts with supplyers. The only thing that stops is the law from the suppliers nation. And if america and rest of europe can sell so can Saab..So the law will not stop.

    Dont know the name of The “Korea SAAB Offer”, but it has incorperated a new feature for making the canards steathy. Its a Z line in the body under the canards, that shows in the sketch. Dont no the works of it, but it is tested and patented by SAAB.

    This important statement. Its put to rest that EF is way better than the other 4th generation fighters. Decision is based on offsets and investments rather than technical abilities. labor costs and labor productivity are two different things.

    Are you kidding? Gripen has the upperhand in offsets, and tech-transfer, just look in norway, with over 180% offset, and full techtransfer on the offer.

    Gripen will be assembled by Tata motors if they win the deal.

    I think dassault should offer to integrate those missiles as cheaply as possible. I think the Rafale would overall benefit from having alternative sources for AAMs, even if one wouldn’t necessarily need more than the METEOR and MICA IR/EM combo. Customers which couldn’t get AMRAAMS, that couldn’t afford to purchase the MICA, or which would a common missile for all their aircraft fleet would look at the Rafale with a different eye.

    The dudes in charge being what they are, they probably are going to force the Mica down on potential Rafale customers… 🙁

    Nic

    Maybe you right, stubburn and pride as french be 🙂
    I hope, for there own good they wake up. Its to big of a deal for france and Dassault this time. And its easier today to integrate new things with all that software.
    And A-Darter is the partnership about, they still need BVR.

    And some funny facts:
    MICA:s radio link is made by SAAB(former Ericsson)

    Sign,

    You are comparing Gripen’s stall speed (97kts) with Rafale’s approach speed (120kts). 😮 To be brutally frank, you are completely discrediting yourself as a so called “expert”… 🙁

    FYI, the Gripen’s approach speed is about 125kts.
    http://www.gripen.com/NR/rdonlyres/D477E794-3F21-45AC-BBC3-D0E535F446E3/0/GRI9182AirDisplay_low060620.pdf

    FYI, the Rafale’s stall speed is below 100 knots. Rafale A flew at 100kts on flight #16 (1 Aug 1986) and 81kts (150kph) on flight #460 (12 Jul 1989). http://www.avions-militaires.net/forum/viewtopic.php?f=1&t=3859&start=0

    So Gripen & Rafale are in roughly the same category as far as lift & minimum speeds go. Since Gripen NG will be heavier than Gripen, it will comparatively disadvantaged in terms of lift and maneuverability.

    I never said i was an expert in anything, i said i was in the business…

    The only thing that pdf tells you is that the approach speed with a extremly short finale and high desend in a special airshow is 125 kt!?!
    Do you really think that is the standard approach on a small roadbase?
    if you do that many manoeuvers in normal approach speed the plane most likely will stall.
    It also tells u that the minimum speed in the show is 100kt!!?
    Du you really think they fly 3kt from stallspeed so close to the ground?!?
    thats the speed of fast walker, from stalling if youre right….hope they calibrated the venturi pipe and that the air is cold and dens 😀

    Do you really think that putting about 15% of all your wingarea in almost 35degres angle of attack wont give you any extra lift?

    [QUOTE=Sign;1310320]Arguing seems go nowere.

    H K – the minimal lengh of a disperst airfield that are 800m, i would not dare try, it if I shore of being up after 600m. That is done today and is still a requirment from SwAF. this is stated in rec. for gripen NO also.
    The maximum weigh has gone up 28% and the thust,22%+, so you maybe right if they choose the lean road. Or maybe you only need to be more aggressive at takeoff? If not, the lean road is choosen its not going to be a problem.
    QUOTE]

    It turns out that Gripen has a approaching speed of only 97kt because of its large, highangle of attack, canards which generate alot of lift.
    To compare approaching speed of:
    Rafale 120kt
    F-18 134kt
    F-35 142kt

    The canards also used as a airbrake, and generates lots of downforce when landed(for even more wheelbraking).

    Getting ready for Super Hornet manufacturing? 😉

    India’s Tata moves closer to aerospace after manufacturing site is approved

    Why do you think it´s SH that ties up with Tata?

    offcourse you can use your gun to shot down the missile, but it would be kind of risky. What do you do if you fail to shot it down? Now the missile got even more fuel left for hunting you down(you speeded against it, when trying to shot it down).
    And would only mere effective on BVR(a long time before impact and time to react). But then again you must be aware of the missile early on.

    Future “smarter” flares should be able to put an AIM9X down, its an ongoing cat and mouse race, that will go on..

    An EMP would also be risky, it can hit you friends 100km from your tail or do civilian damage.

    Maybe a automated “shotgun”(backwards aligned) coupled to a small AESA radar in your tail(1- 4 T/R modules)? can a missile get though a “high speed” wall of led bullets? with its seeker intact?
    The small radar could also be an effective sensor and jammer in your back..
    Doesn´t SU have a back radar?

    Arguing seems go nowere.

    Nicolas10-i left it out because i have already commented it.
    “good one there Rafale!” remember?

    The emtyweight will increase by from 5700kg to 5900-6000kg or 7100kg different sources. The wingloading has steadely increased, but you have to see it as a flexibility, because of the standard loading is still smal.

    The IRST was never introduced in the C/D version jet(tested thou), because it was not found suitable for the scandinavian weather.

    The new radar is going to be alot heavier, so it have an impact on the instability if nothing else is moved back in the plane.

    H K – the minimal lengh of a disperst airfield that are 800m, i would not dare try, it if I shore of being up after 600m. That is done today and is still a requirment from SwAF. this is stated in rec. for gripen NO also.
    The maximum weigh has gone up 28% and the thust,22%+, so you maybe right if they choose the lean road. Or maybe you only need to be more aggressive at takeoff? If not, the lean road is choosen its not going to be a problem.
    But then again i hope saab though through the recuirements before stated them.

    Today with light AoA arment it can take to the air after 350m, so its STOL, just as it was design to be. The 10 min tingie is done today with tings like droptanks and RBS15, mjolner. and ofcourse load more takes longer time or more concripts.

    -Never seen anything about Rafale supercruise, enlighten me. ok maybe on the new engines, how much add thust in the dry part?

    – the Gripen in the other hand is doing it todate sustain 1,1, and will add at least 15% dry thust(as the SH engine), so it should handel the new belly.
    – you cant say a ECM is better because of the size of it. The EWS39 is very efficient, and been proven very good against “bigger systems”.

    I also found this on the engine:
    “The final growth step – Step C – would produce an engine with 30 percent more thrust than the F414 – just under 29,000 pounds, or about 128 kilo- Newtons. This thrust level is nearly equal to the F110 Increased Performance Engine. To reach this impressive thrust level will demand further airflow growth from the fan, a modest temperature increase, a new two-stage low pressure turbine and a new afterburner. “
    http://www.globalsecurity.org/military/systems/aircraft/systems/f414.htm

    “GE has tested growth versions of the F414 since 2004. Through application of advanced 3D-aero airfoil designs, low-loss structural frames, and the latest hot-section materials and cooling concepts, the F414 EDE offers up to 20% thrust increase over today’s F414-400 engine, or up to three times the life of today`’s hot section at current thrust levels. “

    this describs developmentsteps for the F-18, but not integrated on it. The C step and And the F414EDE fits the romurs perfect thou..

    Are you serious?

    They were talking about the ECM, so the airframe of the SU35 or the F15 have nothing to do with it whatsoever in the ECM/electronic warfare grades.

    Saab has disclosed that it teamed with Thales in October 2007 to develop an AESA radar for the demo aircraft. The radar is intended solely for developmental and demonstration purposes, and combines modified back-end components from the Gripen’s standard Saab Microwave PS-05/A radar with an AESA using the same technology as the one Thales is developing for the Rafale.

    Gripen DEMO is a testbed. Not the same as Gripen NG. There are a handfull of suppliers of T/R modules. The alot modded PS-05 backend(much much more processing power), will be the the first gen fighter AESA part that is developed by Saab microwavesystems together with the thales antenna. This backend can fit any supplier(for a integrationcost), no more no less.
    Cant give you any more info on that one.
    You can read that in your own text: “The radar is intended solely for developmental and demonstration purposes”
    This is also goes well with image SAAB wants, “we can integrate anything” “Tailored” for customer.

    Bull****

    Sign,

    If you think a Gripen NG loaded with 8 GBU-12s and AAMs is going to take-off from a 600 meter runway and be rearmed in 10 minutes

    If you think you can fit the same avionics in a 7.1t airframe as a 9.5t airframe (especially ECM and optronics)

    If you think the Gripen NG’s higher MTOW and bulged fuselage won’t affect its lift/drag ratio, maneuvrability and take-off performance

    If you think the Rafale is more underpowered than the Gripen, when the Gripen has proven inferior in sustained maneuvering to both the Rafale and F-16

    If you think the scenarios you gave above are even remotely realistic in terms of their rearm times and sortie radiuses

    And finally, if you like ifs so much

    Then now’s probably the time to ask yourself whether you really know as much as you pretend you do…

    (P.S. I love the Gripen NG, but I think we should stick to comparing it with the F-16/Mirage 2000/Mig-29, not force it into the same league as a Typhoon or Rafale…)

    Your quite the man aren´t you? 😮
    You still compare rafale and f-16 with C/D gripens? this is not the threed for that. Never stated that rafale lacks power.

    This is facts, not “i think”, if official statments are correct(not the roomer thou) and so why doubt saab?, have they ever failed in deliver?, no not in over 60 years..
    The effort at saab has always been the compactness and the LCC of the systems, so yes you can fit a great system in a small compact formfactor. Look at your mobilephone for god sake… and the fact that they can always handpicks the best of things at a balanced price from the world market, swedish, french, american it doesn´t matter. In the NG program they even got the biggest supplyers onboard, no pay for the engine and other subsystems! They are in it for the money longterm!
    When size does matter is the antenna size, but the fact is rafale hasn´t got bigger randome, dont no about the other antennas thou.

    EF is not in, why is that? is it too big? no!, f-18 is still in, is it maybe not in the same league. :rolleyes:
    Infact EF has never won a non-fixt offer. Bae was the only contractor i Austria, and they priced gripen too high…And they still got the contract and got more cash out of it…and dont mention Saudi..

    Were are your facts?
    why dont you get down to biz, and compare the facts. Not your speculations of “how can the manage to that”, its in the offical specifications and thats that. The proved many of those things before and now the have a much bigger engine..so?
    When comparing keep i simple, otherwise you get stuck in tactics and training, jammerfunctions etc. which i did before.
    The comparison was only to prove my point “big trunk” isnt everything that counts in delivering the goods.

    But if you go a long way its best to have the “biggest trunk of them all” (read deep penetration )

    And i still wants a comparison, not “stuck in the wrong league” bull****.
    Which buy the way, is the lamest i heard in years..
    Gripen was the first of the 4 gen and the first that went through an update, so dont give me that crap.

    Dont get me wrong, Rafale is a really lovely jet, but get the facts, and prove my wrong!

    read somewere that Rafale has 1/10 frontal RCS of the Mirage 2000…

    Not in that competion..

    Sign,
    “In the categories of weapons and electronic warfare capability, only Rafale earned the “excellent” grade, according to the officials.”

    I dont see Gripen in that competion due to the single engine..
    Thou its nice to hear that Rafale beats the old F-15 frame, and also the SU 35?!
    Nice one there Rafale! :diablo:
    was it a F3 in the competion?
    Do you have any more ratings in other categories against the SU 35?
