    Yes, he embarrassed himself so badly so i saved his fantasies/commercial/gibberish 😮

    Haha yes. I had almost forgotten about that claim. To bad he stopped posting short afterwards, he was a good source for laughs.

    Nice cartoons, especially the F-3E one, which appears to have all-moving wingtips.

    @A500
    Yeah, that is possible.

    The article isn’t very well in the first place, so I think it should be taken with a grain of salt or two. However other media sources have also said an annoucement of future Gripen plans are imminent, so I guess we will know soon.

    (Oh, and sorry everyone, I actually meant to post all this in the Gripen thread, but missposted it here instead.)

    It’s speculated in Swedish media that tommorow, the swedish air force will present the results of their ‘Gripen roadmap’ studies.

    (Reported) options to be presented, ranging from cheap to expensive:

    1. Gripen E/F with uprated RM12 engines
    2. Gripen E/F with F414 engines
    3. Stealth fighte

    Personally, I very much doubt option 3 will materialize. (*IF* the article is correct)

    It is indeed a great achievement, despite the Gripen being dependent on US goodwill, and isn’t the fighter of choice if you want to be independant from the US (US engine, US radar (until AESA), US weapons mostly).

    Not that it’s that relevant to the point you where making, but just to be a nitpicky bezzerwiser: Gripen’s radar is actually based on a brittish one, i.e not a US design.

    Even today MS21 has not yet been defined, atleast not officially.

    First version five Visby corvette launched

    Version 5 improvements:
    – RCS reductions
    – RBS15 integration. First RBS15 firing planned later this year (About time…)
    – MASS installed
    – & more..

    The technical evaluation assessed the Gripen both in the C/D version and in the E/F version, and the E/F version still fell short.

    From what I’ve been able to deduce the techincal evaluation assesed Gripen C/D and Gripen C/D+ (which is not the same as E/F, but the proposed MS21 configuration at the time of evaluation).

    Low scores where given to capabilities that where not ready/risky/immature at the time of the 2008 and 2009 evaluations.

    Fast forward 2-3 years and the development of these capabilities have progressed significantly, yielding higher scores in a final evaluation and by doing so meeting the requirements. Since meeting the requirments and being the most cost-effective alternative, it won the tender.

    Do we know if the uncertainty factor was weighted on performance measures ? Or does it comes afterward ?

    In addition what Cle posted, SAAB’s chief of exports claims:
    “[…] They used a pretty tough evaluation method, where there was almost no points in what could not be flight tested at the time. Later, they realized that the Gripen is the system with the greatest development potential for the future,” he says.

    Surprised to see it mention ‘EW suite performance’ as one of the weak points of Eurofighter

    Not only it shows that they tried to milk the indians instead of making a good offer, but it also shows that they don’t even respect the indian decisions, which is pretty condescending if you ask me.

    Like (allegedly) Dassault in Switzerland then?

    Expendable decoys and directional IR countermeasures are fairly representative of a modern self-defence suite. As regards the use of AESA in a secondary jamming role, I suspect that the engineering details of this are classified to the point that little useful discussion of its likely effectiveness is possible in an open forum. But once again, if there are any open-source technical papers on the subject, I’d be grateful for details.

    It would be interesting to know in what bands the jamming works and what it’s implications are for frontal RCS. (I guess if it’s stretches the limits of the antenna the frequency selective radome has to cover a wider band of freqencies than what is optimal from an RCS standpoint).

    There is an excellent paper by Paul Bevilaqua (from LMSW, and coinventor of the liftfan solution) on how the JSF came to be.

    An interesting tidbit is how they decided to drop the original delta-canard design due to the fact they thought it would appear less risky with an aft-tail.
