    What happened to IR OTIS and NORA ? And maybe even more important: what is the next step in the development of Gripens’ datalink ?
    I think there was some talk about some kind of satcom ?!

    The NORA projects were only testbenches. Knowhow and functions developed will be incorperated in Gripen AESA (and other future radars uppgrades in like Erieye, giraffe, arthur etc).
    The OTIS IR is seen in marketing presentations for NG, so it´s a choise for any customer i guess.

    WRONG, In Kosovo, Mirage 2000C pilots used to follow their leaders through bad weather and cloud layers (including heavy rain) using the IR Seeker of Magic II.

    Range is reduced but not enough to affect safety of patrol flight.

    You guys lake the most basic experience of military life or what? 😮

    Another KNOWN FACTS Laser degrades WAY faster than IR and the technology isn’t progressing as fast either.

    Military life? 🙂 You people use the equipment i make… i´m not in to the magic seeker thou.. still, IR cant physically find its way through clouds, same as the VIS spectra. Were they flying tight formation? or just 200 m apart:)

    Considering its a lightweight fighter of relatively small size, I guess they cant do an awful lot about the rest of the excess weight, and hence the requirement for a more powerful engine. What you said, however, raises another question. Any idea about the weight of the production variant? Would it be 1 ton heavier or only 700 or so kg as it shouldn’t have any test equipment. So what do current official LCA spec (if any) say about weight?

    If IAF buys some Gripens for MMRCA, they will get some really good lightweight systems in technology offsets..

    Suffiscience in in the lack of understanding of

    1) MICA IR doesn’t NEED range finding simply because its seeker range is already higher than that of the laser beam, 18 km is for an AIM 8L or so, MICA IR seeker range is WELL beyhond BVR as are those of the AIM 9X and ASRAAM.

    2) Laser rangefinding is only effiscient at up to 30/33 km in optimal conditions and its performances DEGRADES WAY FASTER than that of IIR seekers in adverse MTO conditions.

    3) Something else; while you’re a it, learn about optical systems as well perhaps the word “Field of View” will make some sense to you and with more than 30 km detection range you certainly don’t miss much in terms of range with an IR…

    IR degrades realy fast to! You cant see throu clouds or rain with IR, thats a physical fact, not a technical issue. Lasers can penetrate a bit with its high intensity..and also, laserrange varies a lot, mainly because of the output energy/pulstime variation.
    And, you need to know the range for determine if your enemy are in range..otherwise you just wasted a really good missile on a object far beyond range..
    A passive IR detection is always a “2D” detection without range..
    But you should be able to detect a target range passively if you combine two friendly planes in a passive triangulation(a good separation) which makes it “3D” detection. this would be possible with a good radiolink.

    Have you ever seen anything get off the ground quicker?

    http://www.flightlevel350.com/Aircraft_Eurofighter_Typhoon-Airline_United_Kingdom_-_Air_Force_Aviation_Video-10859.html

    I make it 7-8 seconds! With a tank and two asraams!

    If that doesnt give an indication of what exceptional acceleration the typhoon has, I don’t know what does 😉

    I would say 8-9 sec from 2.00 to about 2.09. but thats real good anyway.

    I clocked a Gripen to 10 sec.
    http://www.youtube.com/watch?v=QJQKCUjcslM
    from 3.10 to about 3.20.

    Would be nice to see a SU and the F-22 doing the same.

    Is the gripen radar purely swedish or a product of europeon cooperation.

    The PS-05A is a SAAB Microwave product(former Ericsson microwave) some parts evolved from Blue Vixen radar (United Kingdom), the mechanical parts.

    The new AESA will have a non-swedish antenna(front-end), but rest from SMW(back-end).
    The maker of the antenna is still a buisness matter. Best performance and politics is usually the case the choice.

    Thank you flex297. Very informative.

    The other thing that comes to mind is about the RBS-15. Does it have a land attack capability and would Sweden be game for integrating that onto export Gripens?

    Sounds like a poor mans’s Storm Shadow

    RBS-15s Shadow KEPD 350
    warhead 200kg 450kg 500kg
    weight 800kg 1230kg 1400kg
    range >200km >240km >500km
    Seeker Act-Radar/GPS/Inertial inertial/GPS/IR inertial/IR/GPS/IBN
    Signature nonstealth stealth stealth
    in service -85 -02 ?
    Operators 7 5 3 orders?
    Unit price ? 800000eur 950000eur

    The RBS-15 platform has been around since the the 80:s. the size and warhead was optimized for taken down a “big ship”. So maybe shadow/KEPD will be an littorly overkill for that kind of target.

    It would be nice to know the unitprice of the RBS15?
    Anyone that knows?

    And its also very flexible with land/marine/air launch to land/ship

    Thailand has bought the RBS-15F for its gripens. Dont know if the have land-attack..

    The KEPD 350 will be integrated on gripen, dont know when thou..

    So let me get this stright, the F-35 (JSF) cockpit is “to small for a tall Dutch pilots”.

    Is the F-35 cockpit too small for a tall American, British, Australian or Norwegian, pilot the same height as a tall Dutch pilot?

    If you are taler than 1,93m that should be a problem….

    There is an easy solution for this, all future pilots for the JSF will be Dutch women. The men can fly the transports instead.

    :D:D:D:D

    The longest woman on earth, isnt she Dutch?

    Gripen NG will have increased air inlets to make sure the F414 gets the air it needs 🙂

    The jump in thrust from RM12 to F414 is anyway smaller than from F404 to F414 (ca. 25% vs 35%) since RM12 was boosted by ca. 10% compared to F404.

    L

    Knowone except maybe GE and SAAB or Volvo knows the end-result of the testbenching.

    I never said the doors was closed! More to the point the US will adjust the door as it see fit…………..

    As i pointed out is that US law can only stop a sell, in the same way they stop a f-16. Hope you understand that now… otherwise make some calls to GE…

    It is safe to say the US will control its technology and hardware from being exported to a third party without its consent. To think otherwise it totally ludicrous………..:eek:

    I have already told you how it works….:eek::eek::eek:
    Concent is already made before ex. engineparts are integrated. Otherwise knowone will put the money in it?! Not even GE would put there money in it, like they have(GE does not get a penny from all the integrationwork, but the sales). Companies like GE, Thales, Volvo, Honeywell, Rockwell Collins, APPH, Martin-Baker and Terma is all in it with there own money, SAAB hasnt pay a dime for there integration.

    The only thing in ex. US law that could stop a gripen sale, is the same law that stops a f-16 sale. The US list of blacklisted nations!
    please go back and read the last 20 posts again. Look it up make some calls or stop jibiling!

    General Electric:
    GE Aviation and Volvo Aero Corporation will be working collaboratively on the new F414G fighter engine for the Gripen Demonstrator programme.

    The F414G engine selected by Saab uses a similar architecture to the popular F414-GE-400 engine powering the F/A-18 Super Hornet, with minor changes to the alternator (for added aircraft power) and modified Full Authority Digital Electronic Control software for enhances single-engine operation. The F414 engine is capable of producing more than 22,000 pounds (96 kN) of thrust.

    These engines combine advanced technology with proven reliability, maintainability and operability of its successful F404 predecessor while providing 35 % more thrust, with approximately 750,000 flight-hours and 700 engines delivered, the F414 engine continues to exceed U.S. Navy reliability goals.
