    I’ll have to find the original source, but here is a graphic from a university study. Keep in mind that no RAM was used and only shape was considered. It’s also a generic airframe that conforms to normal VLO design precepts (no right angles, continuous curves, etc).

    Note that the differences between 1Ghz (UHF/L Band) and 12Ghz Ku Band) are not that great.

    Note I’ve also previously stated its complete bullsh!t.

    You’ll have orders of magnitude difference over that wavelength range.

    The results of some harried undergrad student in a final year project don’t invalidate peer-reviewed work… no matter how much it disagrees with your worldview.

    I’ve tested with the pilot skill level turned right down on the blue side which lowers its kinematics significantly. Makes no difference as the f-35 rarely has to evade. The delay this causes to the ooda loop also doesn’t matter as the flankers are identified early.

    Dropped the missiles down to 120b. Still the same result when keeping the front aspect pointed at the red jets and keeping ir signature low.

    In all scenarios and configs where the f-35s can launch before the flankers see them, they win. With ability for stealth aircraft to position themselves early the advantages are just unfair.

    The f-35s ability to show the pilot exactly how close they can get to the enemy undetected just adds to that.

    Whoosh.

    Jessmo23 had no trouble grasping my point. It flew straight over your head though.

    Either way, is the EM accurate? No, its classified. Is the radar inaccurate ? No sir thats classified too.

    A lack of precise parameter information is quite different from a brutally simplified modelling approach that only uses 2 or 3 parameters.

    So we both agree that the simulation isn’t.100% military clearance accurate.

    100% accurate?

    Its probably not even 10% accurate.

    With that said is it that hard to believe that the F-35 could possibly dominate?

    Yes, at least, in the fashion shown.

    The Germans f**ked up badly when they bought the F-104 rather than indigenous designs such as the Fokker DR.1e which had 4 missile mounts per half wing for a total loadout of 24 missiles, go-faster stripes down the side and the latest in lightweight helmet & goggle technology. Killed the European fighter aerospace industry so it did.

    Hence why knowledgeable men like Erich Hartmann protested so much…. no doubt the dodgy bribery dealings didn’t help either.

    If all the planes are armed with HOBS weapons what difference does it make?
    With the exception on a guns only fight any WVR fight with these weapons will be a wash.

    :rolleyes:

    *Breaks out the crayons*

    It means, if kinematics are modelled that simplistically, just how complex do you think the EM modelling is?

    Pardon me
    i dont necessary disagree with your other comments, but how do we know you are an actual marine engineer officer?, i saw people claim they are involved with military all the times, sometimes they tell the truth, sometimes they lie so that other stop questioning their point of view

    Well, if you want something more meaty to chew on – the game supposedly ranks aircraft maneuverability by generation. No further fidelity involved.

    Which would mean the F-35 has kinematics as good as an F-22. Anyone willing to defend that assumption?

    Excellent praise for the F-35.

    In other news, driver says Ferrari 488 is quicker than Ford Escort Mk I. :stupid:

    Ah, lick of paint and she’ll be grand. We’ve more important things to worry about than a wee fire… like beating them welsh-uns tomorrow in Lansdowne Rd.

    That photo looks like an A320 (or family) to me.

    Why are the Russians, Japanese, Chinese, and others using the Same plaform alignment techniques, and continuous curvature, if it doesn’t work?

    It does work – against Ku and X-band radars. [Fighter control and missile seekers]

    Its less effective but still very useful against L and S band radars. [most AWACs, GCI, SAM search radar]

    Its effectiveness is very questionable against VHF or UHF radar. [old or dedicated anti-VLO long wavelength search radar]

    edit: Hence why I’m not sure these command simulations are worth much – but it’d be interesting if the Su-35 had effective GCI guidance how different the engagements would be.

    that rule is wrong though

    That rule of thumb is from NATO for low RCS aircraft.

    50 dBsm is simply too much , low band radar isnt magic , 50 dBsm different is 100000 times different in RCS , which mean according to your logic : even at the least reflection arcs , stealth fighter still have RCS around 10- 100 m2 in 1-2 Ghz , a radar work in 1-2 Ghz will have no problem detecting stealth fighter at range from 300-400 km even in head on

    A good rule of thumb is the change in RCS is proportional to the wavelength^2.

    it not a high school report though

    according to graph the difference in signatures between 10 Ghz and 1 Ghz is around 10 dBsm, which mean 10 times different , i dont see how that remotely similar, at all

    Your right. Its undergrad… Which is not vastly different as far as accuracy goes.

    I know from experience just how hashed together such projects are. They’d one guy doing control, verification of control using flight sim and then RCS.

    according to graph the difference in signatures between 10 Ghz and 1 Ghz is around 10 dBsm, which mean 10 times different , i dont see how that remotely similar, at all

    I would expect variation on the order of 50 dB.

    i dont have the radar scattering graph of F-35 , but a VLO fighter design ( without any RAM ) will have scattering value value some what similar to this

    That is the high school report I pointed out as one that no heed should be paid to.

    No aircraft with empennage has such similar signatures over such a broad spectrum range.

    And you believe the figures floating around for the F-35’s RCS (0.001-0.01 sq.m) are vastly overstated?

    Well.. perhaps you and Andraxxus are both right and the average RCS is actually north of 0.1 sq.m meaning the aircraft is not really VLO and can be tracked at ranges well exceeding 100 km. In which case they’re probably better of with an upgraded F-15E re-engined with the F119. (The Russians in turn ought to scrap the PAK FA in favour of a Su-35Z.)

    You need to understand that RCS varies with radar wavelength.

    Will the F-35 have an RCS of 0.001-0.01? Yes, absolutely, I’m sure from certain angles as seen by certain radar it will be better than 0.001 m2. But, from other angles with other radar, it’ll be orders of magnitude higher.

    As for why it’d be better than an F-15E, the better RCS averages will focus around the Ku and X band which are of course fire control radar and seeker heads.

    But I’m not convinced its standalone* good enough to operate in an environment with long wavelength GCI and opposing fighters armed with medium-to-long ranged heat seeking missiles.

    *By this I mean without F-22 support. So, for the USAF it’ll be grand, for the UK, it will do in a pinch, for the likes of the Dutch…. unconvinced.

    Many forum members who are not American might not understand how “Think Tanks” operate within the Washington DC beltway.

    They are lobbyist scum.

    Yet another instrument of derailed “democracy”.

    Truth be told, you yanks are sadly in an even worse boat than us – and I really think we wouldn’t recognise true democracy if it was actually implemented.
