    No, what you and pfcem are trying to say is that Dassault wouldn’t have known in advance the structural limits of the wing. That’s basically calling them incompetent fools.

    I am saying no such thing. What I AM saying is that all aircraft are designed/built with a safety margin & that 150% of anticipated stresses is pretty much a standard requirement that MUST BE MET & that is it NOT uncommon for airframes to exceed that requirement by a significant margin.

    If Dassault designed their wing for 150% and it broke at 185%, heads would roll in the engineering department. This was a deliberate decision to either increase the airframe life, allow for higher g-load limits (anticipating new flightsuit developments) or increase MTOW/payload – or a combination of all three.

    150% is ‘just’ a standard safety margin. It is NOT uncommon for airframes to exceed that requirement by a significant margin (for various reasons). Of course being that the Rafale airframe broke at 185% is a result of it being designed/built with the intent of exceeding the 150% standard safety margin (that or someone messed up along the line & the airframe ended up being over designed &/or built as a result).

    THE problem is the BS assumption that the Rafale is the only modern fighter that exceeds the 150% standard safety margin. Even worse the BS that only the Rafale is able to pull 11 g. ANY 9 g RATED FIGHTER IS STRUCTURALLY CAPABLE OF PULLING 11 g!

    For one thing, generation is a hypped commercial term, Rafale is only 6 years older than F-22, you don’t design a generation of modern fighters in 6 years, even Mirage 2000 is younger than the US legacy.

    Thanks for once again so clearly demonstrating your ignorance/disingenuousness.

    Then performances depends on requierements as defined by predicted roles, you can use F-22 as a mud-mover in ten years and call it strike aircrfaft in 30 years it wont make this true, people are saying that F-35 is an air superiority fighter because it replaces F-16 but F-16 requierements were for Air Superiority not Strike.

    So those things are nowhere near as simple as what some like to allege they are.

    No, performances DO NOT depend on requirements. Requirements do however define MINIMUM acceptable performances. 🙂

    Who is saying the F-35 is an air superiority fighter? The F-35A IS to replace the F-16, which is the multi-role ‘low’ fighter in the USAF ‘hi/low’ fighter mix. The LWF/ACF/F-16 requirements WERE NOT for air superiority (air superiority was the job/role of the ‘hi’ FX/F-15). Newer/younger/more recent F-16s (begining with Block 25 & progressing to the most recent Block 60) are MUCH more than the LWF/ACF/F-16 of the 1970’s. That is not to say that the F-16 &/or F-35A are not capable of performing air superiority &/or won’t be used for said role BUT customer #1 (the USAF) has a larger/more capable/more expensive dedicated air superiority fighter as part of its ‘hi/low’ fighter mix.

    LM cannot redefine a technical term just because their PR dept sees fit.

    1) Not LM. The USAF/DOD & LM.

    2) They did not redefine the TECHNICAL TERM, they chose to use a rarely ever used & all but unknown to all but a relative few TECHNICAL TERM to define/describe a requirement/capability of the AFT/F-22.

    Back in 1998 even LM quoted Supercruise as ability to achieve and maintain supersonic speeds for extended periods of time without the use of afterburners in their Code One, their latter pathetic attempts to corner out competition leave me completely unimpressed.

    No, in a single article in Code One magazine in 1998 a single author…

    That vs HUNDREDS of USAF/DOD/LM documents/official press releases and other official & unofficial comments before & since. :rolleyes:

    ***

    LM has just changed the definition after it became clear that other types would fit the definition as well. And supercruise = supersonic cruise, it’s an appreviation.

    No, the USAF/DOD & LM began using >Mach 1.5, THEN others decided they wanted to play “me too” & beagn to claim their aircraft could cruise at >Mach 1.0 without afterburner (it was not a requirement of their aircraft nor was it an ability they had previously touted).

    LOL!

    Not Typhoon, not F-35 and not loads of other aircrafts for obvious reasons of weight saving, as for reality it is a such:

    Yes F-35. And since the only place I have seen the claim that the Typhoon is less is from YOU I doubt that as well.

    A little different to your fantasist views of reality isn’t it?

    Not at all. Pretty much says what I posted. Just different wording (I tried to keep it simple so even YOU could possibly understand).

    185% of Ultimate load is a buit-in margin of 35%, the one used “in order to assess the built-in margins, allowing subsequent performance increases or further developments”, for a normal load factor of 9.0 g.

    No, 185% is where the Rafale airframe broke during testing & there is nothing out of the ordinary such a number. It was designed/built to the same ‘built-in’ 50% safety margin as all aircraft & is as typical it exceeded the required margin.

    That’s over 8000 h at 9.0 g loads and 7.000 h at 11.0 g.

    BINGO!

    Designed/built to 8000 flight hours with 9.0 g limit but able be increased to 11.0 g at the cost of 1000 less flight hour life. NOTHING SPECIAL!

    At least the fleet won’t be grounded because the airframe brakes up in flight mid-way through its service life.

    Nice try but the USAF F-15 fleet has ALREADY EXCEEDED its designed/built flight hour life. Their flight hour life has been doubled and while ‘necessary’ to keep the fleet in service since Congress is/was too cheap to replace them when they should have been, has been shown to be questionable.

    Now, how much ultimate load reduction have F-35 B and C seen to be limited to 7.0 g and 7.5 and how much built-in margin is there? 😀

    F-35B: until structural testing is completed (& the results made public) the only people who ‘know’ aren’t going to say. But unlikely as much as you want people to believe.

    F-35C: little to none.

    ***

    pfcem,

    It’s not just a matter of handling the load. The components are not simply put under a load equal to a certain gravitational equivalent, they are subjected to rhythms of waves that increasingly rise in amplitude. Not only that they are subjected to multiple harmonically imbalanced frequencies of force waves at the same time, just like a plane will be subjected to in real conditions. The Rafale went through testing that superficially appears to be no different than any other modern western fighter program.

    Yes I know. I was trying to keep it simple by only dealing with the standard 50% safety margin & breaking point since there are those here who have proven themselves over & over & over again of being incapable understanding even basic principles.

    Not only was there nothing special about the testing of the Rafale, there was nothing special about the results.

    I am not going to respond to the troll directly but…

    The Rafale was designed with a structural load limit safety margin of 50% just like every other aircraft. When an aircraft goes through structural verification testing TWO series of tests are conducted. The first is pass or fail where the airframe is stressed to 150% of its ‘structural load limit’. The airframe MUCH PAST THESE TESTS with no damage or structural weakening so obviously airframes are designed/built to withstand structural loads MORE THAN 150% of their ‘structural load limit’. Assuming the airframe passes the 50% safety margin tests it is THEN subjected to another series of tests to deternine the ACTUAL breaking point of the airframe. The Rafale broke at 185% ‘structural load limit’. There is nothing out of the ordinary about that. Hell breakages not occuring until >200% ‘structural load limit’ is not exactly unheard of!

    To put that another way, an aircraft rated at 9 g is actually tested to structural stresses 50% GREATER than expected to occure at 9 g so EVERY 9 g rated aircraft is easily capable of withstanding >9 g. Even with its FCS limits F-16 pilots are known to pull 9.5-10 g with no ill effect other than a ‘slap on the rist’ if you will from his crew chief for the additional safety inspections that are required.

    No pfcem, M1.5 dry was KPP for ATF, not definition of SC. supercruise was >M1 dry according to Lockheed Martin.

    LM changed their “definition” later on when others could supercruise as well, and LM felt they couldn’t afford that.

    Do i need to quote LM from back in -98 once again ?

    No, supercruise is the term chosen to define/describe the KPP/capability.

    The USAF/DOD/LM ‘changed the definition’ TO THAT, AT THAT POINT. Do I need to quote HUNDREDS of USAF/DOD/LM documents/official press releases and other official & unofficial comments? :rolleyes:

    LATER, other countries/companies wanted to play “me too” & suddenly started touting their ability to cruise at >Mach 1.0 without afterburner even though it was not a requirement of their aircraft & had not been touted before.

    ***

    pfcem = 😀

    Cruise will be the subsonic sub-Mach at which your engine SFC will allow for the highest number of Nautical Airmiles per Pounds of Fuel used in this regime.

    Supercruise will be the supersonic Mach at which your engine SFC will allow for the highest number of Nautical Airmiles per Pounds of Fuel used in this regime.

    @obligatory

    Why do you even bother, the boy think supersonic starts at M 1.5.

    Wrong on all three counts.

    ***

    Could you provide a source to the above?

    AFAIK the >1000nm mission is a strike mission.

    Several books & other published works (I would not doubt it is not on the internet somewhere as well). The Encyclopedia Of World Military Aircraft (2000 edition published by Barnes & Noble, Inc by arrangement with Amber Books, Ltd) is the one & took off my book shelf to double check.

    Now as to this ‘1000 nm strike mission’, that is ‘radius of action’ which INCLUDES the range of the Scalp/Storm Shadow.

    Surprisingly nobody has brought it up here but a Rafale with two 1150 L CFTs + three 2000 L drop tanks…THAT might have a COMBAT RADIUS of 1000nm. But then you are talking about 8300 L (14,634 lbs @ 6.7 lbs/gal) of external fuel in FIVE additional tanks! Thats more external fuel than internal fuel & hardly fair/intellectually honest vs the combat radius of the F-35 with internal fuel alone.

    Turkey Orders 30 F-16C Block 50s etc. for $2.9B

    Turkey isn’t an ‘Arab country’ but THIS is 30 more F-16s for the Middle East.

    http://www.defenseindustrydaily.com/turkey-orders-30-f16c-block-50s-et-al-for-29b-02671/

    On Sept 28/06, the US DSCA (Defense Security Cooperation Agency) notified Congress of a possible Foreign Military Sale to Turkey of 30 more F-16C Block 50 aircraft, as well as associated equipment and services. The total value, if all options are exercised, could be as high as $2.9 billion. This sale is in addition to Turkey’s $1.1 billion upgrade program for its existing F-16 fleet, which aims to bring all of its aircraft to a common configuration. More than 200 F-16 aircraft currently make up the backbone of Turkey’s current fighter fleet, and this marks the 52nd follow-on buy of F-16s by 14 repeat customers. Over 4,300 F-16s have been delivered to 24 nations. The final Turkish F-16 under this contract will be delivered in 2013.

    That’s completely irrelevant. The only relevant thing is whether its range on internal fuel was enough to meet mission objectives.

    It IS relavant. Unless the F-22s at Al Dhafra were taking joy rides (or secret missions) DEEP into Iran or such, OR Al Dhafra was like some US exercises have been where the F-22s ‘stay in the fight’ for extented periods of time while other aircraft refuel & return to the fight, they have PLENTY of range on internal fuel to meet mission objectives at Al Dhafra.

    I believe the Rafale has a combat radius of more than 1000nm (but I don’t know how much more?)

    Air-to-Air mission with FOUR EXTERNAL TANKS.

    ***

    You are correct, with 3 X 2.000 l tanks, 4 AAMs and two 1.300 kg Scalps/Storm Shadows at M 0.83 cruising speed it is slighly slower than the M 0.95 of F-35 for a much longer range.

    Only if you include the range of the Scalps/Storm Shadows…

    BTW an issue NEVER brought forward by the F-35 supporters; how on hearth will L-M make it turn at more than 5 g with an A2G load composed of 500/1.000 lb bombs?

    Pylons aren’t built in Klingon steel.

    So let’s wait and see when all the operational limits are known where it exactly falls, for the time being, its performances are visibly inferior to the European fighters in the A2A role, whatever the US guys read about F-16 and F-15, it doesn’t apply to these, they are not of the same generation.

    LOL

    ***

    First of all it would also apply to F-22, then a Mirage 2000 already can spank F-15/F-16.

    What are you smoking?

    Dismissing what you don’t have with F-35 is yet another way to rewrite history, but infortunately it is the opposite of what every F-22 pilots are saying about kinetic energy.

    I guess when it comes to performances the real step backward was made by L-M when they designed the F-35 but it is to be expected because after all it IS a strike fighter as opposed to an air superiority fighter optimised for the role.

    Do you even read what you post to see if it make ANY sense whatsoever?

    You tried to imply it when mentioning US fighters and European fighters requierements.

    I did no such thing.

    That’s NOT 25.000 ft and a DASH speed of 1.6 as opposed to LWF turning speeds which were in a bracked going 0.4 Mach higher than what you write…

    You clearly have no idea what you are talking about.

    Is that a FACT? (Again?) 😀

    Yes.

    WVR superiority fighter yes.

    Sorry but there is NO WAY that a WVR only fighter is an air-superiority fighter.

    They BOTH were; the famous USAF Hi-Lo couple.

    Nope. The F-15 (hi) was the air-superiority fighter, the F-16 (lo) was a WVR only fighter.

    LWF was a programe with stringent requierements for performances adapted to the Air Superiority role, these requierements are NOT those of F-35 which instead is optimised for the Strike role. io.e lower ceilling and subsonic cruise.

    Dream on. The LWF was NOT intended for air-superiority & even the Block 1 F-16A was MUCH more than the LWF was intended to be.

    Which resulted into a M 2.0 capable fighter thanks to the combination of requiered Mach and ceilling.

    F-35 is NOT requiered to have the same performances at the same ceiling so the M 1.6 is perfectly consistant with its designed role, whatever way you try to spin it.

    Err, the LWF was only a design study which was used as the starting point for the ACF (which the F-16 became).

    The F-35 IS required to have similar performance.

    YOU are the one spinning.

    In the A2A role.

    In EVERY ROLE & then some. But yes, the air-to-air role as well. Thanks for FINALLY recognizing that. 🙂

    You repeat yourself and got it WRONG. TWICE.

    The truth hurts, yes and it is WHY you try to rewrite evey stament, document and historical fact to fit your stories of a design which is not what you try to make up it is..

    No YOU are wrong as has already been demonstrated.

    No it is NOT, it is a designed Maximum as opposed as a known performance it means that they expect it to reach this designed Max speed, not that it is THE requiered specs which was 0.1 M lower btw.

    I know the truth hurts but the text in purple is a DIRECT QUOTE of the requirement. Sorry but a ‘designed Max speed’ of Mach 1.6 is inconsistent to the requirement. It is ALSO inconsistent with demonstrating Mach 1.6+ “with a full internal load”…

    Well if you comprehended the slightest what DASH means then you wouldn’t spend so many time trying to demonstrate whatever you try to demonstrate.

    DASH is the SPEED above which it wont go for numerous reasons, design, lifespan and other, no matter the internal load.

    End of debate.

    subsonic cruise with supersonic dash speeds comparable to F-16 and F/A-18
    Demonstrate Mach 1.6+ “with a full internal load”.

    Mach 1.6 is a MINIMUM, not a maximum.

    SO, READ again, and comprehend what Operational datas are, what they are there for because if it was for you managing the A-F, these aircrafts would have a 5 years service life, a 500% increased operational cost and would be 1000% less reliable.

    Again, already demonstrated to be incorrect ‘data’ contradicted by official program documents.

    ***

    What you guys are conveniently overlooking is the real empty weight of the aircraft and the fact that it goes up with systems integration and redesigns.

    No we are not.

    We are ALSO not confusing (or deliberately misquoting) PRE-WEIGHT REDUCTION WEIGHT with/as POST WEIGHT REDUCTION (or production/service aircraft) weight.

    I didn’t miss anything; i stick to what is officialy posted for some very good reasons, the first one is that these figures are also designed goals as for the finished product with all systems integrated, what they do now with the airframe is only to try to make it happen because just in case YOU missed it, the redesign of some structure and systems cost weight.

    No you don’t you DELIBERATLY ignor what is officially posted AND DELIBERATELY misquote ‘data’ which has been shown to be inaccurate.

    Even though you continue to ingor it, AA-1 ACTUALLY WEIGHT is slightly BELOW its target weight…

    NO. You cut the nonsense trying to make of F-35 A2A mission its primary, it is OBVIOUS that it is NOT and that if it had been, its design would be drastically different.

    Good God man. NOBODY is trying to make of F-35 A2A mission its primary. It is a MULTI-ROLE fighter.

    You might not comprehend what aircraft design points are, what design features are and what requierements are but it is no reason to pretend that they do not results in a given set of performances.

    When you know a lot more about it, come back and try again, i’m sure your PoV will a little different by then.

    It is YOU who does not comprehend.

    obligatory,

    Don’t be a fool. Of course the F-22 is in a leage all its own. But it is only because of how good the F-35 is (& the result of some thinking that with it the F-22 is frivolous) that statements of its superiority EVEN OVER THE F-35 were made.

    Of course the F-35 is not on par with the F-22. That DOES NOT mean that it is not better than everything other than the though.

    So who wants to use the F35 as a countries primary air defender now?

    Everyone who realized that they will never get the F-22.

    ***

    Otherwise said, how we see twisted truth and facts in a permanenty basis in order to make of F-35 what it is not designed to be. :diablo:

    And we see that it is people like YOU who are twisting &/or misrepresenting the facts in order to TRY to make the F-35 AND what it was designed to be something other than reality.

    When someone said it was a stealth, supersonic A7, the F-35 fans were all shocked just forgeting that the A7 was the most advanced striker of its time which is what F-35 is designed to be.

    While I can not speek for everyone, I knew full well what the A-7 was decades ago & have never forgotten. I ALSO know full well that those who sa the F-35 is a stealth, supersonic A-7 are doing so in a derogatory way to deliberately disreguard/misrepresent the F-35’s flight performance & capabilities as a FIGHTER.

    The F-35A was designed to replace the F-16. To not only be a highly capable striker but a highly capable (2nd only to the F-22) FIGHTER as well.

    So here go, we have guys like Pierre Sprey who suddently are senile and doesn’t know what they are talking about and Boyds energy theories are gone down the gutter not applying anymore (how grateful is that to the guys who ave the US the F-16), Maximum designed Mach, Operational cellings and other datas for predicted performances sudently becomes minimas etc.

    Err no, here we have technology & air combat having progressed beyond the theories of the 1970’s but Sprey & Boyd still living in the 1970’s. Pilots who have ACTUALLY FLOWN the F-35 confirm that a COMBAT LOADED F-35’s flight performance is (except for top speed) similar to a CLEAN F-16C Block 50’s.

    Maximum designed Mach, Operational cellings and other datas are still what they have always been. But it is disingenuous ingoranuses like you who are deliberately misrepresenting program MINIMUM performance goals as design maximums.

    Hang on, we all know Gripen NG is designed for M 2.3 isn’t it? And Rafale perfs are in realiity classified it CAN supercruise at M 1.6 with 3 X 1.250 l external tanks and 8 X AAMS, As for Typhoon it is M 2.5 and S/C at M 1.75 no less.

    About as accurate (in reverse) of how you try to represent the F-35 vs what it really is.

    ***

    I still wonder what this crap with SC is about. Depending on condition, a flight with first stage AB can be more economical than squeezing the last sh!t out of military power juist to brag about SC numbers.

    Very true. See the Mig-31 for example.

    Sustained supercruise only makes sense in the most economical regime and this is hardly M1.78 for the F-22 even if this number was true. If it’s a short-term value only, then it does not constitute ANY operational advantage because in emergency other aircraft can make it even much more faster with engaged AB.

    Nobody is saying that Mach 1.78 is the most economic speed for the F-22 to cruise at but it can OPERATIONALLY do so. And remember that the F-22’s performance requirements include a combat radius which includes 100nm at >Mach 1.5. EVERYONE who knows jack, knows that while cruising at >Mach 1.5 the F-22 is reducing is combat radius/range vs if it were cruising at M1.7 while guzzling even more fuel, especially if the opponents won’t hesitate to engage the burners and to accelerate to M2.2 twice as fast.

    Q: Does Australia have any other choice?

    Other fighters weren’t given much attention were they?

    As already pointed out, Australia had & look at several choices.

    Australia was smart enough the realize that is was not going to get the F-22 & that given that fact, the F-35 was the obvious best choice.

    ***

    Supercruise as the USAF/LM views it, is the maximum, non-afterburning, speed the plane can reach while having the most tactically significant range per pound of fuel used. In other words, it is the optimized speed for range/fuel consumption under supersonic conditions. To use economic terms, it is the point beyond which you see diminishing returns.

    No, supercruise is being ‘able to achieve and maintain speeds in excess of Mach 1.5 for extended periods of time without the use of afterburners’.

    And please lets stop this anal BS of only cruising at BEST (most economical) cruising speed is cruising. Aircraft are perfectly capable of cruising (achieve and maintain speed for extended periods of time) at a wide range of speeds. Hell, the Mig-31 was designed to ‘cruise’ WITH minimal afterburner! By no means the most economical way to go about it but the way the Mig-31 was designed to operate. The F-22 was designed ‘to achieve and maintain speeds in excess of Mach 1.5 for extended periods of time without the use of afterburners’.

    ***

    pfcem has come with a figure that Raptor’s top SC speed is Mach 1.78. Even this figure has not been proven yet, but funny enough, two pages later I already see you claiming that Raptor actually has its optimum cruise speed at M1.78. 🙂 I am really looking forward at the claims three pages later on. You guys seem to never get enough of the overhyping.

    No the USAF/DOD/LM publicly released in Feb 2009 that the F-22’s supercruise speed is Mach 1.78.

    I personally assume that the maximum quoted SC figure will be exactly the one achieved at full military power. There is no logic in assuming that Raptor can fly faster at 70% throttle setting than at 100%. And there is no logic in assuming that Raptor can actually SC at Mach 1.9 at 100% throttle but LM would only claim M1.7 because this would be the most economical speed.

    The USAF/DOD/LM did not say that Mach 1.78 was the maximum BUT without official/confirmed/reliable sources contradicting such assuming this to be at close to (if not) full military power is not unreasonable.

    ***

    Sorry YOU are talking in circles.

    Supercruise will be the supersonic Mach at which your engine SFC will allow you for the highest number of Nautical Airmiles per Pounds of Fuel used.

    You are arguing the that regime at which cruise is achieved matters which it does not, since subsonic and supersonic are two different regimes it is obvious the resulting endurence will be dependent on the drag involved in these regimes.

    The FACT that you refuse to ADMIT that the definition of cruise won’t change with the regime speaks volume about your motivation which is NOT to learn but stick to your fantasies.

    Your lot.

    No, supercruise is being ‘able to achieve and maintain speeds in excess of Mach 1.5 for extended periods of time without the use of afterburners’.

    Well in the case of F-35 it IS and BTW 1.5 doesn’t let you pull 11.0 without a lot of damages to the aircraft.

    :rolleyes:

    No actually, its structural load was also reduced for the same reasons of weight saving and it also suffer from wingdrop issues which means integration of spoilers to try to sort it out.

    More weight, less performances AGAIN..

    No, ONLY THE F-35B!!! The F-35A & F-35C remain 9 g airframes. Here is a clue, the F-35B & F-35C where ‘sited’ (as per Department of the Navy policy) as 7.5 g BEFORE the weight reduction program…

    “War emergency” is NOT what i am taking about, i am talking about NORMAL operation with a structural load suffiscient for keeping the airframe within its lifespan, not overstres it.

    But we already know that you NOT comprehend the word LIMITS and its meaning.

    Under NORMAL operation with a structural load sufficient for keeping the airframe within its lifespan the F/A-18 & F-35C HAVE 9 g flight envelopes. The USN policy to soft limit them to 7.5 g (except when deemed necessary & cleared for 9 g flight envelope) is to increase their service life/reduce their maintenance costs.

    So WHAT? It doesn’t change the laws of pyisics, if it can’t pull enough g like many AIM-120 before it it will miss the target.

    Thanks for so clearly demonstrating that you do not understand what NEZ means.

    Think UFOs is you wish to get an AIM-120 to turn like a Python and btw it is NOT a 50 g-class AAM and F-35 is FAR from being able to go around a Typhoon or a Rafale in a turning fight.

    Have nice phantasms. :diablo:

    I did not say the AMRAAM was a 50 g class AAM like the Python IV & other WVR missiles. In fact what I posted clearly indicates that it isn’t & thus requires a bigger circle (lower g) turn in order to make a 180 degree change in direction. BUT an AMRAAM has PLENTY range to make a comparatively large circle (lower g) turn & still engage its target.

    Who ever said the F-35 is able to go around a Typhoon or a Rafale in a turning fight? What you fail to understand is that IT DOES NOT HAVE TO! Good God man, let the missile do its job (which DOES NOT require you to point the nose of your aircraft at the target to do).

    ***

    Yes, I would, indeed.

    Yes, and it is my opinion. Any problem with that?

    Yes. You are stating YOUR OPINION as fact.

    ***

    I’d say that lack of range on internal fuel to meet mission objectives would have been a MUCH more obvious reason to carry bags. If they needed to hide the radar signature, radar reflectors would have been the obvious choice instead of carrying otherwise unnecessary fuel tanks around..

    The F-22 has greater range on internal fuel than any other participant fighter in the exercise. Nice try though.

    Even more funny is that all images in the video with Raptors carrying bags were shot back home AFTER their return to the US that means you know sh!t about whether any bags were used down in UAE or not.

    No, pictures & videos FROM THE EXERCISE show the F-22 with external tanks.

    It constantly amazes me how easily you believe anything you WANT to believe.

    Talking to yourself again I see.

    F-22 undefeated at Al Dhafra

    http://www.flightglobal.com/blogs/the-dewline/2009/12/f-22-undefeated-at-al-dhafra-2.html

    Note that photos & videos from the exercise show the F-22s flew many (if not all) sorties with two 600 gal external tanks (obviously to hide their true radar signature from ‘prying eyes’) yet were still UNDEFEATED even in WVR engagements.

    I which way does this counterdict what i was saying, and btw, you are WRONG there are two variants below 9.0 g F-35C is 7.5 g…

    Thanks for once again demonstating that you are a troll.

    I was confirming that US fighters are built to at least 1.5, not contraciding.

    No YOU are wrong about the F-35C. Just like the F/A-18, it is fully 9 g capable but the USN has a policy of limiting them to 7.5 g so as to increase their service life/reduce their maintenance costs. The pilot has the ability to exceed the 7.5 g soft limit & utilize the aircraft’s full 9 g flight envelope during times of war or emergency that call for it.

    What matter here is the capability of the AAM to pull enough gs out of the rail and turn toward a target, if possible one 180* behind it underr the highest load factor as possible.

    Seeker FoV or not if the AAM can’t do it fast enough, in a tight enough turn, it will miss a fighter chasing the shooter in its six.

    And ‘current generation’ WVR AAMs have NEZs that extend to most of the entire frontal hemisphere. Full sphere NEZ is a goal of ‘next generation’ AAMs. Even ‘current generation’ WVR AAMs do not require the pilot to point the nose of their aircraft at the target.

    That too is important reaosn why i doubt very mush an AIM-120 with lower initial acceleration, smaller wings surfaces and lower g load will do the trick in the real HOBS engagement envelop.

    Think Python IV only with a bigger circle…

    Is that a FACT?

    Yes it is. There is nothing of a generational leap from the US ‘teens’ (& the Flanker/Fulcrum/Mirage 2000) to the Eurocanards. If fact, about the only “improvement” is extenting the high g flight envelope – which with the introduction of 4th & 5th generation WVR AAMs is not as important as it was when the Eurocanards were designed.

    NO there was never any mention of US figthers in their requierements this is PURE invention as is most of what you post.

    Nobody ever said there was any mention of US fighters in their requirements.

    Absolutly NOT and btw, performance-wise F-35 design was taken to a lower level than LWF requierements.

    Only in your dreams.

    The LWF was optimized for operations from 30,000′-40,000′ & from Mach 0.6-1.6 with maximum turning performance from Mach 0.9-1.2.

    Revisionism, as expected.

    Historical fact. YOU are the one trying to revise history.

    F-35 was designed as a STRIKE fighter, F-16 as a PURE air superiority fighter = LWF, with higher Mach and ceillings.

    No the F-35A was designed to REPLACE the F-16. The LWF was NOT an air superity fighter. It was a WVR only fighter. The FX (which the F-15A became) was the US air superiority fighter. In fact the LWF was just a design concept which was used as the starting point of the ACF. And thank God those in charge of the ACF had the foresight to recognize the limited usefulness of the LWF & designed in growth potential well beyond the capabilities of the LWF which allowed the F-16 to become the multi-role fighter it became. Even going from YF-16 to F-16A growth potential was added – most notable a 7″ increase in nose length & 4″ increase in nose diameter so as to be able to incorporate a radar of larger size & capability that the APG-159/F-5E radar previously envisioned.

    GEEEEEEEEESUS. 😀

    Now that’s the pinacle of the funny 2009 quote contest.

    The truth hurts.

    And these are NOT KPP but designed operational maximum or DASH; including the ceillings at which they are to be used.

    No they are BS which have already been shown to be BS that is contradicted by official program documents.

    KPPs have been published in other pages of L-M doc and well know what they are, they do not include Machs; thanks for amusing me.

    Thats right. In fact the speed requirement states “subsonic cruise with supersonic dash speeds comparable to F-16 and F/A-18“. Sorry but there is no way you can claim a design maximum of Mach 1.6 with that as the requirement. :p The F-35 is even expected to demonstrate a dash speed of Mach 1.6+ “with a full internal load” (thats ~23,000 lbs of weapons & fuel). How fast are the Typhoon & Rafales with ~23,000 lbs of weapons & fuel vs their designed maximum? 😉

    And since I feel like demonstrating further that you don’t know what you are talking about & are taking requirement MINIMUMS & claiming them to be design maximums…
