    Thats really odd flex – because I’ve seen the EF about 8 times now and I can’t see how you describe its flight as sluggish….

    so ur comparing non-fbw MIG-29 with 400 hr engine life with 4000hr engine life F-16. Remember engines loses thrust due to wear and tear. only 60 to 70% of thrust is available in real life.

    I am comparing a stable Mig-29 vs the relatively unstable F-16 that has an engine compromised between performance and endurance yet still is reportedly superior to the Mig-29 above the low speed regime. If the F-16s engines were tuned to deliever 400 hours of thrust – imagine how much extra juice they would pump out.

    @star – grow up.

    @doomlordis – “It has a lower wing loading , better thrust to weight ratio” – those are pretty irrelavent – as you dont know what the lift/weight*drag ratio is. Nor do you know the actual TWR at alts and speeds – let alone the T-W*D ratio.

    Just because of the sensation that was created over the 90s low and slow Su-XX airshow routines – doesnt mean the F-15 doesn’t out maneuver it at relavent combat speeds – they are probably quite evenly matched. See the Mig 29 vs F-16 examples over Germany. Everyone seems to base the Su-XXs outstanding maneuverability on its airshow displays – this is pretty foolish as many have claimed – yet so many people still talk about it.

    Essential agility now occurs at supersonic speeds and high altitude. There is a real performance gap between legacy designs and new models like the EF. So significant it will definitely shrink the NEZ of enemy weapons – and therefore relatively – increase your own weapons NEZ. This is the area that systems engineering/avionics can only do so much to bridge – it’s where raw performance is coming back and is becoming relavent. It is a bit like when the first afterburning jets started hitting the scene after the earlier gen jets. There is a substantial performance gap – try watch videos of jets at 40 000+ foot and see how relatively sluggish they become to what you see at an airshow.

    Venky it’s clear you – like so many others – have little or no understanding of what is actually relavent, most of the time, in aerial combat. What Su-XX does, is bleed energy at a alarming speed while doing any of those post stall maneuvers – while watching the Typhoon – see how it seemlessly transitions from maneuver to maneuver – without significant speed or altitude loss… That is truely impressive and truely relavent.

    People in the typical 90s TVC “fanboy” camp – that judge the Su-XX as amazing because of their post stall maneuvers are foolish at best. One reason the Eurocanards and the F-22 are not legacy aircraft – is because they have grasped a new concept in aerial warfare. One of top end agility and acceleration at high altitudes and speeds – things you cannot grasp by merely watching an airshow. Numerous “well respected” forum members here can’t grasp this concept – so I don’t blame you for not either. It’s not sprouted by the ignorant nor the Russian PR machine that has up till the PAK-FA – been stuck with legacy designs.

    Hmm, I think I read it from a more substantial source, yet to found, than a letter. Its a rather bold statement to be made up, totally out of the blue don’t you think? I believe there is truth to it, after all I think the article was speaking words from an RAF pilots mouth.

    Of course I don’t know how it does it, but I would like to keep it that way, keeping the EF ahead of competitors.

    True about not giving hard nose evidence, but I’ll see what I can dig up….

    Nah – its based on a letter thats floating around the net. Which was sent to one of the mags and published… It was extremely shoddy work – and astoundingly published. If you believe it – you might aswell believe the EF pilot who apparently said the F-22 is invulnerable in BVR and makes the EF look like a F-16/5 in WVR. I’m not saying nothing has happened between these two jets – although thats the official line – I’m just saying be careful about what you believe in. Especially if it concerns things like the electronics/systems on a jet – they are the most complex and secret of all the systems… its well known that even allies like the UK and the USA – USA and France – don’t operate their radars/EW kit to its full potential in any DACT. 🙂

    I’ll go find it, cannot remember exactly where its from, but it stands out in my memory because its a big point. I think it may have been an RAF typhoon article in AFM, not sure but I’ll go find it and post the relevant info.

    It was based on an unknown letter with an unknown source… sent to one of the UK based mags. It was completely unstubstantiated – with no proof other than word of mouth. If that’s what we go by then there are similar claims from people around the Nellis range that say the F-22 is pretty much hammering the EF BVR in these “supposed” DACTs and that the EF is only competitive in WVR – where it can “see” the F-22. Even then in WVR – it’s claimed to be a similar to a match up of F-16/5 vs an EF – while we know the EF hammers them.

    Now I personally don’t believe in any of these claims – especially since they are contradictory. While they generally have little to no truth and hardly any relavent context. The point is – don’t be to quick to quote unstubstaintiated rumours – that have no real source… other than word of mouth.

    As Dj says… The F-22 – if reports can be believed – has without a doubt proven its combat capabilities – if RoE permit – as the foremost AD/Anti-system platform out there. Exact specs are irrelavent – as it brings a synergy to the fight that other aircraft can’t compete with. Whether it is relavent – or whether it’s cost effective are seperate issues. But questioning its ability to sweep up hordes of legacy jets – is finally a non-issue, even amoungst its greatest detractors.

    Wow that must be one of the best – if not the best routine – I have seen any jet do. Thanks for the upload.

    And even from real-life we know those numbers are wrong. They present the F-35 as worse than the F-16, yet we know that the non-weight-optimized AA-1 F-35 is routinely out-running and out-climbing its F-16 chase planes

    Yet they present the gap between the ‘superior’ F-16 and the F-35A as being larger than the gap between F-22 and F-15! (slide 79)

    it doesn’t even begin to pass the sniff test

    That’s because comparisons like TWR and Wing Loading are pointless – not just for strike aircraft – but for any fighter. They don’t reflect on the performance of an aircraft at all. They are effective for “ball-park” studies as the yanks would put it – they only give a general idea of where the performance should be. I have always understood this – but since going to university – and after being exposed to some of the test facilities – you get an idea of how truely one dimensional these statistics actually are – it gets quite funny to see journo’s quote them to support their own jet. TWR – is meaningless – T/W*D ratio is much more indicative of performance. Yet this is still dependent on a whole host of variable factors such as AoA – the Fluid and Thermodyamics of the engine at non static/non sea level conditions – altitude – velocity – use of external stores(which have a massive aerodynamic and structural effect – and many many more. Wing Loading is a disgrace aswell – it gives nothing relevant. One would need to rather understand the overall lift-drag ratios of the jet at differing altitudes, velocities and angles of attack – and what effect external stores have on the overall pressure differential above and below the jet – not to mention how the engine responds at angles of attack. Then base all that information in a ratio against weight for any relevant data on maneuvering performance.

    But rather – silly/ignorant Journo’s – like the public – not being exposed to any of the real technical data in any of the engineering reports on these jets – take publically released static/sea level thrust values – wing loading figures – while just looking at the jet in an attempt to judge its drag with their eyes – and semi get a feel for what they believe out performs this and that etc and jump to stupid conclusions. I am simply astounded Rand did a cut and paste job from some of Kopps stuff. I truely believed they were privy to some of the real stuff – working closely with LM/Boeing/DoD etc.

    Then why aren’t they attacking the idiots who make false claims? This scenario does not support the “clubbed like baby seals” claim. Arguing against the study because somebody with a particular agenda lied about it is ridiculous. That’s like blaming the victim for a crime.

    I disagree – what I’m saying is: what’s the need for a study based on a hypothetical scenario that isn’t realistic. Why paint your own systems black – make them vulnerable to public attack from a study that has no relevance or merit in its own right.

    I am all for a sound logistics study – they are essential for any Air Force/mission planner. But a cut and paste job that shows limited American conventional forces acting as part of an unrealistic system*; is pointless in my opinion – especially if it has the side effect of threatening Jobs programs like the JSF.

    * – where only 6 F-22s + Tankers + AWACs; but with no Navy/Taiwanese/Japanese(from Kadena’s destruction) are defending Taiwan from hordes of J-11s/IRBMs/SAMs etc –

    AASM is certainly a huge advantage for Rafale, and will remain so until Typhoon has a stand off PGM (the new Brimstone, perhaps).

    Or perhaps GBU-39.

    Yes swerve – but unless this example models a surprise attack on Taiwan. The relevance of the study should be called into question – especially if they resort to using technical data from Carlo Kopp – and compare half-truths like wing loading and TWR – I’m still a bit dumbfounded they do.

    If it lead to the conclusion that: F-35s being clubbed like baby seals – you can see how potentially damaging it is to certain programs. So its relevance must be called into question. I don’t think anyone has been ruffled by the fact the chinese win – I think what is causing the grief is the fact that they use a study like this to jump to silly conclusions – especially journo’s – who then create an anti-program X atmosphere in a country that is potentially going to aquire a certain jet – when the whole excercise or study is firstly not based on that fighter but on a system that – is operating without many of its key components. Its like saying a top end Ford Focus is a better than a 3 series BMW from 1994 without ABS – without electric windows – without power steering – without airbags – etc etc. So the question is how relevant is the study – especially if it threatens big jobs programs like the JSF – when its context is irrelavent?

    Yes swerve – but what about the Aegis engagement envelope. Surely a cruiser located on the east side of Taiwan – would cover the Tanker support. I can’t see why the authors remove that aspect in the analysis.

    All calculations based on data from Jane’s. From a purely technical aspect – I am thoroughly shocked. I always thought of RAND as an insightful and respected third party organisation. I assumed they were privy to information that was and is unavailable to the public – akin to DERA in the UK. From a purely logistical point of view their conclusions are based on simple logic – but some of the technical stuff absolutely shocks me. I hope this isn’t the level of work they do for the more – classified reports.
