    even if we dont know the length of j10b, which we kinda do, we should know the lengths of either: j7e, jf17 or the pl8 under the j10b’s wing or pl5e under the jf17’s wing. Using pl8, j20 is between 20,38 and 20,04 meters long, depending on whether we use 2,95 or 3 meters for pl8. using pl5e’s dimensions we get 20,27 meters for j20.

    thank you, bager, do you happen to have a source for all that? A paper or at least a website?

    Basically, you’re saying that catapults on both carriers are powerful enough to launch planes at their mtows even if there is zero wind and carrier is stationary? I must say that goes against what is always cited about carrier operations. why is wind over deck important then? for landings? For having the luxury of not using the catapults at 100% their strength, thus saving their life expectancy, as well as not stressing the aircraft airframes as much?

    So, french decision to make their carrier’s top speed 25 to 27 knots is perfectly valid from a/c operation viewpoint and it doesn’t impede a/c efficiency in any way?

    i’ve been to that website but i don’t see a simple equation for my problem, like i gave an example of. there are only more complex equations used which have several unknown variables to me. i need an equation which only shows the relative dependance of wavelength change to the detection range.

    probably the latter. though, this looks like quite a thorough refurbishment. probably not unlike the one il76 went through before they became awacs. so perhaps more il-76 based awacs are coming?

    alternatively, if it IS y20, then it looks to be quite similar to il76, almost a copy, taking its worst trait – the fairly narrow fuselage. i do hope, for chinese sake, that were looking at an il76.

    that looks like il-76 to me. even the hatches on top match.

    while j20 doesnt look like a very good knife fighter, using just guns, it does look optimized for supersonic regime. it may not be able to keep turning and turning and hold its own in a long dogfight but it does look optimized for a very fast first turn or two, getting the nose pointed wherever it needs to be pointed at. And it certainly looks as if it is meant to carry a LOT of fuel. that might mean inefficient engines or long range. or, probably, something in between.

    IF the next gen missiles versus next gen defensive systems can regularly achieve 30-40% kill ratios, i’d say its design is very prudent. If it turns out missiles (versus same gen systems) will offer just 10-20% kill ratios, then its design might turn out to be too risky.

    I think you are forgetting Chinese assembled ones with Russian kits, 95 of them.

    Russia delivered 76 of them then 200 local assemble deal is signed, 95 produced. After that J-11 came and after than J-11B.

    So, ~400 is correct.

    the way i am interpreting the newsbits over the years the original j11 WAS the localy assembled su27sk. over time, more and more chinese parts were used and less russian made parts were used. then at one point, assembly ceased after some 95-100 units of j11 and production of all-chinese j11b started. scramble’s orbat certainly supports that theory as they list some 170-180 su27s and j11s combined.

    the list seems accurate enough for most types – save for j11s. there is no way there are so many su27s and j11s. it is well documented that at best some 100 j11s were produced before production switched to j11b model. and it is also very well documented there were, all in all, 76 su27sk and su27ubk (combined) delivered in the 1990s. I’d therefore lower the flanker family variant figure by some 100 planes. also, what about adding bombers to the list? H6? does anyone know how large h6 squadrons are? i have a feeling they seem to change sizes and that plaaf and planaf squadrons might have different compositions and numbers…

    I keep reading about those underwing tanks being 1150 liter ones, not 1500 liters ones. Does anyone have a proper source on that?

    I would like to see how MIG 29K with 1064 element Zhuk AE and R 77/R73E will do against Super Hornet Block II 🙂

    Considering r77 and r73e are missiles with some 15-20 year old technology in them and havent been updated since – probably not too well. mig29 with rvv-sd and especially rvv-md might be a different ordeal.

    So question is whose seahawks are those. Who, besides americans, uses such seahawks in the operations near libya? What unit do those seahawks belong to?

    it is not clear if j11a can use r77, true, but chronologically, didn’t the j11a come after the last batch of ubks? that would point to likelyhood of all the flankers coming after the ubks having at least same avionics.

    alternatively, if the planes were modernized after being bought, during their service, it is even likelier all the j11a have r77 integrated, as why would anyone in their right mind modernized the trainer flankers but not the flankers meant for combat?

    as for j10b, it sure does look like a new position for rwr, especially if you look at j10a, which has a similar thingy on the side of the intake, but here in j10b thats missing and the new thingy is moved half a meter up, near the canards.

    So, basically, pretty much ALL of the flankers chinese have in service are wired for missiles with active radar guidance? We’re talking over 300 planes here. And with over 200 j10 and some 100 j8f that gives a sizable force of relatively potent planes. Never thought of that before…

    don’t the su30 have horizontally cut tail tips? and ubk should have tail tips cut at an angle? these have straight tail tips…

    Different avionics may mean a lot of things. Adding new software to existing hardware is already different avionics in some regard.

    And considering design freeze for j11b was probably sometime before 2007. it is very much possible and probable avionics design for a plane that is only now testing will be frozen a few years later.

    Being a naval plane, additional mods for naval search and integration of antiship weapons may already constitute different avionics. Now we don’t know if perhaps j15 will be purely a fighter, but if it isn’t, new software for new weapons is enough to say it has different avionics.
