    No idea which design they were referring to, but it could be the N/D-102, since Dornier wasn’t working on any other fighter design back then..it was sort of a YF-17 follow-on design.

    FlightGlobal article with a picture of N/D-102

    and

    Another one

    the N/D-102 did look like a design with a lot of potential. Good view for the pilot with a proper bubble canopy, a large delta wing meaning low wing loading and some clear influences from the YF-17, such as the notch in the wing that allows boundary layer air flow separated by the splitter plate to flow onto the wing. Interestingly, this feature is present on the LCA as well.

    The story in the first link says it was to be powered by two F404 “NON-afterburning” turbofans to reduce IR signature. Very interesting.

    TAI launches study on Turkish-built next generation fighter

    http://www.xairforces.net/images/news/large_news/100112_Turkish-Air-Force_F-35.jpg

    The Ministry of National Defence awarded a contract in August to TAI to launch an 18-month feasibility study on the so-called TFX programme, said Ali Yilmaz Guldogan, vice-president of strategic planning and industrial co-operation.
    A 40-strong staff comprising representatives from the Turkish Air Force, TAI and the undersecretary of defence industries is now preparing to deliver the study in early 2013.

    Any hint whether it would be a single engine Gripen- or F-16 Falcon-sized fighter or a twin engine Eurofighter/Rafale-sized one?

    Here is a summary

    http://forum.keypublishing.com/showthread.php?t=85882

    Oh, same old story. The RCS figure in that FOI paper is just an assumption made for the sake of modeling and simulation.

    One reason why they reached that result was that they were simulating the Meteor+Iris-T and not the AMRAAM-AIM9 for the Gripen.

    Another reason could also be the reliance on a combination of low RCS, and sophisticated EWS.

    It seems everybody says the Gripen has “a low RCS” without actually knowing what value it is.

    Does the Su-35 being bigger than the Gripen actually equal quality over quantity?

    I’m fairly sure SAAB would argue the Gripen is of equal quality to the Su-35. 🙂

    Thus a larger number of Gripens versus a number of Su-35’s would be quantity and at least equal quality versus quality?

    Yes, being able to fly farther with more missiles is certainly higher quality.

    yes indeed you could argue that.. but you could argue that
    a smaller number of high maintainance Su-35s might be cheaper to operate than a larger number of low maintainance gripens. You’d have to take into consideration the costs of pilots and personnel to take care of the Gripens and space concerns at the air base. you can even argue that more gripens in the sky are more noticeable than a smaller number of Su-35s

    its just a generalization.. I don’t know how much more Gripen NG would cost over an Su-35, especially since we’re talking about the different scales.

    Well, the Swiss government decided to have more of cheaper Gripens than a smaller number of more capable, larger & heavier alternatives.

    What prompted me to start this thread was a claim by Saab in 2009 that Gripen NGs defeated much larger Su-35s at a ratio of 16 to 10 in its 50 simulations.

    http://www.flightglobal.com/news/articles/gripen-revives-war-of-words-over-norwegian-fighter-assessment-327317/

    This claim should obviously be regarded with suspicion – computer engineers have a saying: garbage in, garbage out – but it gives me an impression that Saab believes cheaper lightweight fighters can overwhelm more expensive heavy fighters by numbers. At a given amount of money, you should be able to buy and operate more Gripens than Su-35s.

    I don’t think there is such an example what the OP is after for. History of aerial warfare is short, and many of the conflicts have been decidedly one-sided. Also, the belligrents have tended to use similar type of aircraft. Maybe closest one can get is Vietnam, where usually lighter NVA fighters caused some problems for generally heavier & more complex US aircraft, but did not really ‘defeat’ them, more like opposite in the end. Also, ‘lightweight’ side was numerically very much inferior.

    One can find isolated, tactical examples, of course – most notably some WW2 era heavy fighters like Bf-110 and P-38 which were sometimes badly beaten by lightweight fighters, but that evidence is anecdotal in nature and there are always counterexamples.

    Yes I am almost reaching a conclusion that there is no such an example.

    Location, location, location. If the Mirages stayed at high altitude, the Harriers could ignore them. No threat to the ships. They didn’t have enough fuel to use their speed advantage once they got down & dirty. Their nominally BVR R530s weren’t effective enough at BVR ranges to make a difference.

    AFAIK, the only engagement between Sea Harriers & Mirage IIIs was with equal numbers, two on two. One Mirage shot down, one used too much fuel to get home & diverted to Stanley, where it was hit by Argentinean ground fire.

    Comparing numbers of Mirage IIIs to Sea Harriers doesn’t mean much. The Mirages were always part of raids with other types.

    Yes, forcing the adversary to fly greater distances to fight is in effect a virtual attrition.

    you could argue many Luftwaffe battles against Allies.

    My question is “quantity overwhelmed quality” in air warfare.

    The Luftwaffe had less fighters than the Allies in 1944-1945 and didn’t have an overall edge in quality either.

    Vietnam?

    No the US had superiority both in quality AND quantity.

    I don’t know if either India or Pakistan achieved clear air superiority in the 1965 war, but India had more fighters than Pakistan, who committed a few supersonic F-104s into battle. AFAIK no Indian MiG-21 saw action in that war.

    The key is to achieve local superiority, it don’t really matter if you have more if they are late-comers, so communication & speed is also critical.
    Luck also plays a part.
    Like Patton said – “be there the fastest with the mostest”
    http://en.wikipedia.org/wiki/Battle_of_Midway

    It worked well enough for americans to pitch 5 patton tanks vs 1 tiger,
    only 1 patton tank was expected to survive the encounter, but they could afford it while germans couldn’t.

    good read

    What I want as a valid example is not a single battle, but an entire war.

    If I’m not mistaken the report straight up says that Gripen NG has not been evaluated. And that all figures covers the C/D version of Gripen.

    Isn’t the “MS21” the same standard as the NG?

    The EF is said to supercruise at Mach 1.4, wich is impressive

    Would be truly impressive if conditions are also specified – for how long, at what altitude and carrying what.
