    -The NG AESA “on the market”? You are jocking, I suppose…At least 4-5 years to tune it … if ever operational.
    -0.1 m2 with combat load??? Again, you’r just kidding…
    -I am aware of the tentative IR -OTIS…never heard of any operational…
    -Where you fanboys screw it is when you combine the two afirmations: 1) grippen can fly for 2500 km and 2) grippen can carry 7 tons; you conclude that 3) the grippen can fly 2500 km with 7 tons…which it can’t :diablo: Not to mention that the range figure seems to be pulled of SAAB PR department’s asses.

    No bother fanboy, its all offical data. stop twisting and bending. Have you ever seen rangedata with maxload ever?!
    If you have no interest in the real world figures, get out..or get a grip

    I’m sure it will be some orders for the terrible Swedish fighter… Some 6-12 of them for 1th class AFs such as Hungary, Czech Rep or Thailand…

    any claims of yours is only flaming with no fact what so ever :rolleyes:

    just as a note:
    AESA ES 05 raven is a product thats on the market and flying.
    >0,1m2 RCS is better than the most.
    IR is known to be at best
    2500km range, on internal is not “point defence”
    a cold day in sweden on 28000ft is like a hot day over the sahara on 28000ft, its no difference..:D
    How often do you use a “decent” loadout of more than 7t (C version) or 9t (NG)?!
    Look at the number of fighter orders in the western world the last 5 years and see how many of those has gone in favor of gripen..extrapolate that.

    According to Vishnu Som it will be configured with Enhanced Performance engines. It will also be 9G capable 😎

    Sustained G force, is made with more thust,
    instantaneous turn rates is made by aerodynamics and airframe strength.

    Instantaneous turnrates is the one usually referd as the 9 G limit.

    So a G-limit will not change with new engines!

    So do I, if you add the Roadmap improvements to Rafale F3 (F3+) it becomes a totaly different story again.

    Untill we know what this version will really be like, i prefer not to speculate.

    I look at Gripen and always am impressed even with the baseline version though, this is why i was comparing (as a succesor in the class) to Mirage 2000.

    At any given moment the last updated will have an advantage, More and more advantages lies in softwares…and extremly hard to compare

    But at the moment hardware wise, gripen has an advantage in:
    Sensorfusion with other gripens and systems
    Probably RCS and IR signature

    Rafale has advantage in
    more power and endurance, optical systems
    and EWS.

    The smartest tactical use and pilot skill will probably win….
    but thats my 50 cents…

    NG will change all that and have a bigger advantage, and F3+ will probably have it when time comes….but then NG+ apear! 🙂

    Article excerpt from Defense Industry Daily

    South Africa to Cancel its A400M Order
    05-Nov-2009 20:32 EST

    In April 2005, South Africa’s Public Enterprises Minister Alec Erwin expected the cost of the SAAF’s 8 planned Airbus A400M medium-heavy military transport aircraft to be EUR 830 million. That converted to R 6.5 billion at those exchange rates, or about $177.75 million per plane in American dollars. South Africa reportedly intended to take delivery of 8 of the A400Ms from 2010-2014, with a further 6 on option. Ordering those additional 6 aircraft would reportedly have pushed the total contract value to EUR $1.5 billion, or about R11.9 billion at those exchange rates. When the deal was signed in December 2006, the price for 8 aircraft and initial fielding had risen to R 17.646 billion, or almost $2.5 billion: about $308 million per plane.

    Meanwhile, South Africa bit the bullet and decided to upgrade its 8-9 aged C-130B Hercules planes. The first SAAF C-130Bs were delivered in 1963, and badly needed additional upgrades and refurbishment.

    Subsequent delays to the A400M program were set to either extend the C-130Bs’ service, or force reliance on charters, even as the A400M’s likely costs grew. That SAAF aerial uncertainty has only grown, now that South Africa has become the first country to pull out of the A400M program…

    those props looks avesome! it sad it turns out this way..

    AIM-9L has Indium Antimonide (InSb) head that works in 1-5um, wavelength, so that’s IR.

    Are they fired from 1kW emitter??
    Let’s see how far will you be able to scan with average medical X-ray installation. 😉

    Just kinging with you, i would not use gamma or cosmic either way. Its not healthy..:)
    But a Q-swiched LRF in IR or IIR does emit 1kW in a pulse its more like a 1 GW..

    OK Sign; i am not trying to be confrontational for the stake of it or have a go at you.

    My point is, this “HOBS” mode for AIM-120 was only thaught of because AIM-9X Block II wasn’t ready and F-22 didn’t have HMS.

    It doesn’t have the design specs to be a true HOBS capable missile, it doesn’t accelerate fast enough and doesn’t have the lift either.

    HOBS was developed from the most agile IR AAMs of the time (Python III Magic II) which already had High Off-Boresight maneuvring capabilties but lacked the guidance/seekers to offer the real HOBS envelop.

    If these maneuvring capabilties are missing, the problem remains the same, close-on, an AIM-120 wont be able to pull enough g to hit a target 180* behind the shooter in a defensive envelop, that of EODAS detection range.

    What you are looking for is a missile that turns straight off the rail and can sustain the turn so as to hit a pursueing target within this buble or else you wont be able to cue it with EODAS or even detect it at all.

    Other than that any BWR could be loaded with HOBS softwares it won’t make them capable of close-in defense.

    IR AAMs are meant for self defense not offencive BWR.

    I cant say anything against you there, its no comparison.

    But the AIM-120 got more burntime to get to target than a magic, and it turns alot faster then the jet that derailed it.
    So it should be good thing for AIM-120 users, but not as big step as shortrange IR HOBS was…

    The most important performance number for the F-35’s mission is it’s fuel fraction. Name another fighter that compares?

    The Rafale is a great airplane, but it’s actually too small for the mission. Which is why it hasn’t sold well.

    As for the whole F-35 vs Rafale, well, the F-35 will either shoot it down at BVR range or simply fly around it without engaging.

    As for the 11g claim as the design load capacity of the Rafale, if true, that just tells me that the Rafale is overdesigned and hence, heavier than it needs to be for the mission. Which would be an even larger detriment considering it’s size.

    unstable/canard means less load at the same g..(alot bigger momentarm between the weight and the controlsurface) and rafale got a smaller wingloading(more wing less bulky) in a light configuration. So it does not need to be “overdesigned”!

    Awesome! Do you have a link for this?

    this is no suprise, due to TILDS, all sensordata is triangulated. It is whats called is the sensor-fusion(gripen sense) and is part of gripens strongpoints.

    Gamma or cosmic waves has quite long range and those are quite short 🙂

    What i AM saying is what i wrote.

    NO point trying to pass AIM-120 for an agile IR AAM.

    I got into the debate late, and i am not trying anything like it… a shortrange high of borsite IR AA is ofcourse more agile… thats the point of it.. just pointning out things thats need to be taking into considuration, in a “normal” comparison. Not an apples with pears comparison.

    No point trying.

    All AAMs have smart and more energy-saving algorythms, there NO such thing as increasing LIFT and g tolerences in software.

    so youre saying theres no difference between missiles in, detector, the use of detector information, and the output from these datachanges?! Then theres no need for missiles to get any smarter in the future then…its all been done.

    The only thing that reduces the need for maneuvering is difference in speeds between target and projectile. The larger the difference the less g a projectile needs to pull.

    a missle that dont have any problems with chaffs or flares, and can predict flightpaths faster, more accurate and better need less manuvering..

    The EODAS is farther along than the F-35 as a whole. As of March 09, it had over 240 hours of flight time and over 25000 hours of lab time. We are well beyond those numbers now.

    Please, y guys, is this Gripen News Info?!!?!?
