    how much would the difference really be

    I think actually the difference is big…just by adding weapon bays complicate the design…that not counting with the new production line, i wonder if Saab would want to make their own “JSF”…Japan, korea and many other countries would be interested..all under the Saab advisement..

    But still your point is valid, wonder if they presented that option to Norway

    *edit* nevermind i dont want to start all that mess again..

    Anyway about the topic, if somebody have the mechanical diagram of the 14’s swift wing?, how it controls it angle? with gearing or with mechanical breaks?

    I dont know if Saab has offered the same product/program of a 5th gen plane based on the grippen?, like they did to korea?, and more important did Saab offered that idea to the sweden AF?

    Some of you guys are spicing with paranoia the f-35 requirement (“the russians are comming” stuff).., but Norway is already into the JSF project?

    Still there is uncertainly about the 35 and it final cost (which shouldnt be above 80 mill, shouldnt…but could be) Why politicians would like to block the 35?, why would they preffer the grippen?, Saab share produccion components with norway industry?

    (edited idea , coz i confused all the whole thing :))

    Not so. Remember that Mig-25 is fast at low level also (1300kmh, earlier versions 1200kmh). It is in fact capable of 11 G pull-outs with subsequent safe landings, which was proved.

    But we are talking about over gs and special cases there, i agree that ppl understimate the agility and airframe strenght of the foxbat (specially the agility at height), mainly due cold war myths , and because ppl claim the g limit as 5-4 gs, when that is under supersonic speed, anyway at low level the plane is not a dogfighter specially against a 4th gen plane

    BTW…welcome back…

    One radar to pick up the scatterings of another radar in a network? Is that possible? Aren’t their accuracy and latency issues? I don’t know much about radars, but I have trouble imagining that this really works, with all the different refractions, waveform issues and angular resolution. Hmmm….

    Waveform, refraction, different modulation, etc are the same problems that must face all the radars with their own returns, if you share the same frecuency, share the same radar receiver or RWR systems (which also helps you to identify friendly radar signals -then it could come the sensor fusion thingy-) you should do it with out problems, remember that at least the Irbis has (due it antenna) almost full dimentional reception capacity, so i dont see real any problem there

    Edit: nevermind guess i just did over-complicate the things with the other explantion…what im saying there is just pasive radar tactics, no more no less, now of course you add networking on it

    Lmraptor, you must remember that the radar signal is not absorbed by the airframe (at least not most of it), the return tries to go away from the radar source

    I really dont see too hard to arrange a fighter/radar formation to catch the signals and by info networking (data link) tell where are the stealthy planes, so some planes will get the data that others arent recieving, especially when you look the raptor/35’s geometry (which don’t send the signals upwards), so a formation with a distance of 50-30 km of 2 planes, one working as the receptor of the other should do the job, when u get a RCS of 0.XXX, it does not mean is the RCS of the plane, it means it true RCS went to another place..remember that even the 22’s engine fans are optically visible at certain angle…and im not talking about the RF visibility

    PPP, sensor fusion is nice, but in this task the networking , and receiver/electronic standaritation is what do the job

    About the grippen, any sign of these famous conformal fuel tanks?

    I’m really wondering, all that conformal tank fashion (rafa,typhy, and this one), is not a bit too lazy answer for a better range?

    Really where is the advantage?, i mean if you redesign the airframe , you will have a strengthed fuel tank and will save a lot of weight

    So why not better just redesign the airframe or just strenght it , and add 2 more hardpoints to attach more tanks?

    In my very humble opinion, CFT’s is one of the worst ideas on modern aerospace tech

    Edit: Is ok, we also should consider how further the wing and lower airframe could be strenghted before to increase the weight in a significative level, still the instalation of it adds unwanted weight instead to redesign a bit the airframe, not counting the restrictions of an attached device

    BIO when i was talking about “out of the box” was not about the “last moment tactic”, was about how most ppl think about warfare and the tech involved, is not about to push a red button and end of the story 😉

    There are options, and the ppl that are involven on that knows it

    Yes, while the technology moves forward , it imposse limits to the older systems, but you must know where are these limits, and with out any kind of evaluation (like djcross did) you will fall in the “newer means instantaneously success”, but that sometimes happens, sometimes is mixed achieve, and sometimes is just a void and senseles claim, yeah stealth tech makes the things harder and many sam systems would need to deploy at least in some proportion active heads to their interceptors and new software and data link architecture to use correctly it tracking beam, but nothing impossible to modern tech

    Guys , if you see the thing on the search radar, adjust your tracking radar and missiles , combining inertial flight with command guidance and active seekers, or delaying the target adquisition from SARH , any stealthy plane will have a bad day

    You should think out of the box, with the conventional tools that you have, that is what tactics is all about

    Only if USA rejects to sell F414 to Gripen NG………

    Saab did not have studied that alternative? at least common instalations? is possible some buyers would want that option, which for me does not look impossible

    Would it be safe to say that “stealth” could give u an RCS of…..a bee? or something

    There are different tests which are done with different frequencys, some of them are way above the frequency of figther radars, so if you do a test with K band (20 Ghz) and drops you the “bee” RCS that does not mean is the same RCS that a Irbis will be see

    Also is a bit more complicated , since the Radars actually dont work in that way as an static RCS

    And then i have some pretty strong doubts about the shape effectivity of these new planes…since them have challenged all my knowledge (not godlike, but fair enough) on optics and EM

    Ok..lets move on 😉

    Any possibility for the grippen with the EJ200?

    -The EF is too interceptor oriented
    -The F-18e is too heavy ,14 tons…is almost another su-30, but with all the issues of the Hornet
    -The mig-35 and the rafale are the most balanced planes
    -The grippen coluld be the great surprise

    Th MMRCA is the great oportunity for the Rafale, which IMO is better suited for the contest than the EF

    The fight will be between the Rafa and the 35

    But then it have the AESA issue, so the Rafale will have AESA for the contest? or wont get it in time?

    Don’t get me wrong, but it looks like Mig is more interested to win the MMRCA than Dassault….

    I dont think so, and im start to thinking these famous 0.00000X values are the peak RCS value under certain angle…now check how is the variance of the RCS on a conventional graphic…

    …can it? http://www.cheesebuerger.de/images/smilie/konfus/k020.gif

    Never saw that movie, dont pay a lot of attention on these figther-movies, but never underestimate the craptastic holywood powers 😉

    The best movie involving fighters was the “flight of the dark angel”…or something like that, no cheesie “young ameicans cool pilots on their uber fighters”, no “evil commies, muslims, ruskis”, was about an excelent american pilot, but depressed to madness, his kfir and a nuke ;), and his instructor that thought he knew all about him, never liked the plot turn in which he kills all his family, the story would have been more interesting

    Anyway..expect another generation of OMG! this XY plane is the best uber crap ever! 😉
