    RECO-NG is the same as DB-110 on F-16, if needed similar system will be integrated into F-35 multi-mission pod

    Mig-31bm, having witnessed your efforts at derailing various Russian threads over the last while, your ad hominen attack, off topic and unwanted here, is very unwelcome.
    Your post has added ZERO to the thread or its actual subject. It has been an interesting ON TOPIC discussion until your unwanted off topic post, and it really should on another day be reported as a blatant attempt at derailing

    Me derailing various Russian thread ? nope. The only Russian thread i usually on is PAK-FA one, and even then i rarely comment there. And iam not trying to derailing this thread but rather a head up for others about the accuracy of LEG posts. Because, it has been my experience that, while they seem very long and informative at first, they more often than not contain many mistakes ( or better said just made up numbers).

    If the wall of text came from someone else i would have been impressed, but remembering what LEG posted and his style (mixing a bunch of military terms to sound like “someone in the know” then mix it up with facts and factoids both real and imagined) in https://forum.keypublishing.com/showthread.php?2902-F-32, i have no choice but to be skeptical. Just a head up, long posts may or may not be accurate

    In air sound only travel slightly faster than cruising speed of aircraft and much slower than missiles so I think it is rather useless for air defense

    Its a Titanic level disaster. Or the shuttle Columbia. For one of the 1st operational F-35’s to be broad sided by an old Soviet missile is a historic disaster

    yet it is every bit as legit as Doomsday in 2012

    As to why the J-20 emphasizes radar, larger radars are supposed to be able to jam smaller radars.

    Jamming doesn’t work based on which side have higher total transmitting power. If that was the case, you will never be able to jam ground radar with ECM pod on aircraft. Jamming effect depend on the power of your own reflection/jamming signal. So you can easily jam powerful radar with weak ECM pod as long as your RCS is low or you stay far from the radar.

    Also, another point of interest might be the J-20 radar. Now that we have precise measurements, the radome is about 1.3 meters, implying about 1 meter aperture diameter, or a 30% superiority in size over the F-35.
    There’s this article I’ve been meaning to find of late that reports the J-20 jamming and spoofing older Chinese AESAs. With the large diameter, what this implies is that the J-20, with same generation radars, can suppress the F-35’s radar system, nullifying its inferiority in stealth and forcing the latter to rely on EODAS

    In real combat environments with surface clutter, jamming and decoys, all stealth fighters will detect and track each others by IRST and ESM long before they can see each others on radar.

    If the J-20 is flying higher than the F-35, the latter can’t utilize its EOTS while the J-20 can, meaning that the latter is now out-sensored by the J-20 and has to rely on its defense systems

    There isn’t enough altitude difference between J-20 and F-35 for J-20 to stay out of EOTS field of regard and aircraft cruising near their service ceiling will fly pitch up slightly anyway to generate more lift.

    Common sense vs “eyeball markI forum level integrated joint RCS measurement apparatus”

    If only RCS is as simple as common sense…

    About rafale RCS you can find a good rafale documentary which is available on YouTube :

    https://www.youtube.com/watch?v=q7RYZovAj54

    Bruno Revelin Falcoz, the father of the rafale, states directly that Rafale frontal RCS is equivalent to a smal bird which puts it in the VLO category. That would be for a “clean” rafale of course

    I don’t think Rafale is in VLO category in the same way J-20, PAK-FA or F-35 are..etc.
    One can also look at the scattering chart below and say a clean F-16 has RCS of a bird from some very specific aspects, while it is technically correct, it doesn’t make F-16 a stealth aircraft. Rafale, Eurofighter, Gripen are likely to have reduced RCS in the same way F-18E/F is

    Except the F 35 meme has historic precedent. This was an actual postcard

    If you make a meme everytime fighters penetrate air defense then you can make dozens of them too. It doesn’t change the fact that this story from conspiracy site is utter nonsense.

    This will also throw some cold water on your meme …bla bla bla

    Do you understand sarcasm?.

    There is no direct hit in air defense, but missile explode near the plane. SA-5 missiles are old, so we do not know if warhead works properly and at what distance it detonated. If too far from plane, than it only damage it.

    The possibility that this incident happened is the same as this one
    Malbrunot reported that on January 12, Israeli F-35s took out a Russian-made S-300 air defense system around Syrian
    http://www.businessinsider.com/f-35-combat-mission-syria-2017-4
    In short, zero possibility

    M1A2 and M2 are demolished by 100-150 kg IED but F-35 can take a direct hit from a missile that has 200 kg warhead, flying at Mach 5. Seem legit .It take a special kind of stupid to believe that.

    B-52 is still used because it is a big bomb truck that can launch missiles from 5000-10000 km aways. You don’t need a fast aircraft that is several times more expensive to do that.

    providing stand-off EW range counter-VLO capability or/and burn-trough capability in heavy jammed environment.

    The table is strictly in no jamming environment.

    I would expect half wavelength spacing, hence a 2x2m array @ 4000 elements,

    S band with 15 cm wavelength (2Ghz).
    4000 elements=> 64 vertical and 64 horizontal lines
    If the aperture is square then its length 64×15÷2 = 480 cm or 4.8×4.8 meters with half wavelength spacing.

    S band with 11.5 cm wavelength (3Ghz) need 3.6×3.6 meters array for 4000 elements.
