    And no, I do not know the name of J-10B’s AESA, just as no one knows the name of F-16E Block 60’s IRST. :rolleyes:

    What is the J-10B’s frontal aspect RCS?

    Smaller than an F-16E Block 60’s for sure. You don’t want slabbish titanium engine blades bouncing radar waves back. :p DSI bump has a much greater angle of incidence compared to slabbish engine blades, reflecting less radar waves back.

    Interestingly, early mockup of J-10 in 1991 looked very similar to F-16, with a very similar intake. This is because Israel delivered a Lavi to China.

    I am correcting you, you are wrong. You have no idea what the bird carries, let alone how it fares against its peers.

    What electronic warfare suite does the J-10B have? How does it fare against NG Falcon Edge?
    How does J-10B’s radar fare against AN/APG-80? Do you even know what its name is? I doubt that.
    In what way make the DSI intakes the J-10B more aerodynamic?

    I know F-16E has no DSI, a crucially new technology incorporated since the 2000s. J-10B has it. This implies J-10B is more technologically advanced than F-16E. Name me 1 technology F-16E has that J-10B lacks. :rolleyes:

    J-10B’s internal EW is at the top of the tail. http://www.youtube.com/watch?v=z6dwLp1KFxs

    With DSI, there is no gap between the intake and the rest of the fuselage, resulting in a unibody construction. No gap = more aerodymic. With F-16E, you can clearly see a slabbish gap between the intake and the rest of the fuselage. With J-10B, there is no gap because the intake and the rest of the fuselage are fused as one piece.

    How is the US going to pay for that? http://www.usdebtclock.org/

    J-10B will hardly be a match for F-16E. F-15SG/SE is a different beast, a league above that.

    F-16E Block 60 Desert Falcon has inferior technology compared to J-10B. J-10B is the most advanced single engined war jet in the world except F-35, but the latter won’t be operational till years after J-10B is operational. Correct me if I’m wrong, F-16E doesn’t even have MAWS like J-10B does. J-10B is also more aerodynamic and stealthy due to DSI configuration.

    F-35 v PAK-FA or J-20 depends on who detects the other first. First detection allows that flight (there’s always more than one jet) to bury the adversaries in a flurry of missiles.

    F-35 is like Virginia. PAK-FA (Su-50 in operational) is like Yasen. J-20 is like Type 095. Yasen is quieter than Virginia. This implies it is very possible Su-50 is stealthier than F-35. http://www.brainstormmag.co.za/index.php?option=com_content&view=article&id=4560:the-worlds-most-advanced-submarine

    Is an F-35B a match for the J-20?

    umm umm

    F-15SE is inferior to J-10B which gets delivered this year. It is also no match for J-20. South Korea made the right decision.

    The question we must ask is, does adding missiles to a plane add to radar signature? Certainly from the front due to more surface area added. From the side there is no addition because the missile’s body would block radar waves from hitting the side of the plane. If the missiles are air to air missiles, we know the side shape of the missiles which are round would reflect radar waves better than the slabbish side of a plane, and should therefore reduce the radar signature from the side. From the front there would be a minor addition of radar signature.

    Tanks?

    Do these tanks conform to the mathematics of being lighter outside the aircraft than inside the aircraft too? If g is a constant, I’m not sure that would be the case.

    No, but I’m sure conformal fuel tanks increases radar signature from the front and rear.

    Absolutely correct*…

    Same as when you put fuel on the outside of the aircraft, it is lighter than when you put fuel on the inside… :dev2:

    *Its signature will tend to zero after a short time in the air too…

    conformal fuel tanks :applause:

    J-10B loaded with 10 PL-12 long range air to air missiles has much less radar signature than F-15SE with no load on the outside. Each PL-12 will reflect radio waves away from the side of the plane more than the plane can itself. This is due to the difference between the shape of a missile’s side and the shape of a plane’s side. A missile’s frontal radar signature is negligible. Mathematically, one can show that, putting missiles on the outside of a plane reduces the plane’s overall radar signature.

    It is proven mathematically that carrying air to air missiles outside the plane rather than inside the plane overall reduces a plane’s radar signature. The reason is that, in terms of surface area, a missile’s side is much bigger than a missile’s front.

    Internal payload

    Internal payload matters little. Reflective surface of air to air missiles from the front is negligible due to size and shape of missile fronts. From the size, missile body and plane body coincide and therefore missiles do not contribute to additional radar signature. If anything, from the side, missiles reduce radar signature due to round body shape which reflects radio waves away more compared to plane body which is sort of flat in your face does. :applause:
