    It’s drag remains to be seen, but I’m not sure using the fact that it’s big is the best choice of words to show low drag. As for the range, the 5500km figure is Ferry range(including an aerial refueling), not on internal fuel.

    one aircraft can be big and have pretty low drag…. the concorde was a lot bigger than any fighter and yet could manage to fly supersonically across the atlantic… if you look at the PAK-FA, compared with its size, it’s very “thin” and, overall very “flat”… while internal volume is obviously significant (allowing a lot of fuel onboard) it represents very small frontal surface. WHat’s more, look at the shape of the duct between engine nacelles… don’t you think it looks quite similar to an engine nozzle (convergent-divergent)? I wouldn’t be surprised if that shape adds thrust at high speeds with the two engines blowing hot air on either side of it.

    This thing is made to go fast and to go far while doing it

    An aircraft with such data is to find in a movie only. But it was named “Firefox” if I remember well. Please stay more serious. ๐Ÿ˜€

    seriously, un 1940, making anything supersonic other than a bullet would be “science fiction”… ten years later, first supersonic fighters “in dive only, but still…” were in service

    in “modern” fighters, the russians are usually “late” is in electronics, but as far as aerodynamics and engines power go, they know their stuff… the F-22 can supercruise, and the PAK-FA undoubtably will be able to do it as well… what remains to be seen is how fast and for how long will it be able to do so, but it is a very sleek and very big fighter, so, it should have little drag and a huge fuel load, which should put it very high in these areas…

    @ jdsgn

    as I said, they need to be rechecked, yet, if we want to go by “real true and proven numbers”, we can close this board right now…

    JSF is still a prototype that needs development, so, nobody (not even LM) can say what exactly it can/will do, PAK-FA is even less known, F-22 features a big bunch of “confidential material”, as well as rafale does (in france, basically any precise data in regards to fighters after 1950 is, basically, “confidential” (gotta love the politicians overhere… ๐Ÿ˜€ )

    what can we talk about that’s not partly or completely “unverifyable” for civilians like us? not much as far as it is about combat aircraft

    similarily, you assume the F-35s will be in the air and in the way of the attackers…

    there’s only a slight problem with that assumption:

    you don’t have aircraft on station 24h a day all over your country… on the other hand, the attackers have to organize their raid, they can gather intelligence (satelllites, AWACS etc can be of use on their side too) as to what they may have to face, and then choose the most appropriate moment to attack, coming to attack when and where they see fit.

    When you have to defend, you must react to your oponents moves, which requires good coordination and speed… and if your interceptors lack the latter, you may have to compensate with the first.. if possible.

    When you attack, you are the one who has the initiative and can choose where and how to go in. And if you also have the advantage of speed, chances that an interceptor comes close enough are pretty slim…

    in the end, it’s not about “everything right” or “everything wrong”, but simply an aircraft is a tool designed to do a particular job. If you want it to do another job, it may be a wrong choice, try eating a soup with a fork and you’ll get an idea ๐Ÿ˜‰

    can’t speak for anyone, but as far as I’m concerned, a statement by someone “not anonymous” who was there and stating clearly what happened would be a good start…

    actually, if there had been a press conference and it was an RAF officer saying “we did “that” against the rafales”, and france not communicating about it, except maybe some vague allegations by dassault, I’d simply consider it true and say: “ok, well done gentlemen”

    it’s about that simple

    no, what I mean that, if you look at eurofighter export markets, be it in austria or with the saudis, things weren’t exactly “clear”… (charges in austria and justice “advised” not to pursue investigations by the british government…)

    for the rest, the commercial succes in military aircraft still has much more to do with politics than with the real quality of this or taht particular aircraft…

    Fortunately sales numbers are a better indicator than unofficial sources.

    it’s not that simple, the Mig29 was sold in much bigger numbers than the mirage 2000, yet, is it so much better aircraft?

    Eurofighter was bought by countries who are part of its development (contractually, they had to buy it), and besides them, who else (talking about “honest” sales with no bribes and such things)?

    The mig 21 was produced (and, obviously sold) in higher numbers than any other supersonic jet (little under 11500 aircraft).. was it so much better than its contemporarires, like the F-4 Phantom II or the Mirage III?

    Numbers can be spun to claim anything one wants.. but hardly can prove anything precise about the aircraft performance

    as they say:

    “Propaganda is a science” obvously the one they work hard to master…

    they continue to talk about unofficial claims… yet, you can hardly make it more official than a press conference organisted by the ministry…

    To supercruise or not to supercruise..:rolleyes:

    They wont get very far if they do supercruise you know.
    Not the most fuel efficiant way of travel..

    the major principle of supercruising is to go fast and far at the same time… for the PAK-FA, at wiki they give numbers as follows:

    # Cruise speed: 1,300 – 1,800 km/h (808 – 1,118 mph)
    # Range: 4,000-5,500 km[dubious โ€“ discuss] (2,500-3,100 miles)

    http://en.wikipedia.org/wiki/Sukhoi_PAK_FA

    now, it’s wiki, so, there certainly should be some checks done, but still, even if it does “only” 3000km at 1500km/h, the F-35 won’t ever be able to catch them.

    And how close to our ground radar station can they go before they get tracked?
    I don’t know and eighter do you.

    no, but I do know they know where their potential adversaries radars are, so they can plan their ingress and egress routes to avoid detection as much as possible

    If faced with a stealth adversary like the Pak-Fa, i would think its safest to stay ‘close’ to any ground radar or any AWACS coverage.
    That way you greatly increase your chances.

    what was talked about was the scenario in which norwegians use the F-35 as interceptor. That means they want to use it to catch potentially hostile aircraft before they do their job. The PAK-FA being a potential adversary for the F-35 in that theatre, it’s not illogical to wonder whether an interceptor which top speed is similar to cruising speed of its target will be able to catch anything but thin air.

    If they have to intercept an aircraft, they can’t just stay “near their awacs” simply because the attackers they’d have to intercept in the scenario we are talking about are going after targets on the ground… and couldn’t care less about norwegian fighters (so, they have no reason to go after them)… having your interceptors staying “near the awacs” (even if you have one) wouldn’t help much.

    Now enough with this hypotetical nonsens.

    Thanks

    well, the only thing not making sense was you answer since you obviously didn’t read previous posts to get the idea we were talking about… sorry

    Your assuming many things that wont happen.

    1. The PAK FA knowing where the F-35s are and the direction they are coming from. How does this happen?

    knowing where their bases are can be the first cue… if you go one way, they’ll most certainly go to position themselves to intercept you as you get closer… turning at a certain point, even less than 50km from border would put them out of position.. you can outrun them for maybe 10-15 minutes and then, resume supercruising, wou’ll be at a speed they won’t be able to attain and beyond their missiles’ range

    2. The PAK FA will not be detected by ground radars from the sides and rear. Since the PAK FA’s RCS reduction is clearly forward sector only, detection from the side and rear is a no-brainer.

    and? if it’s coming towards the territory the delayed detection will mean they (norwegians in this case) will have to scramble their interceptors and have them going at max speed to try to get into position… if the incoming aircraft change course, the whole “intercept” may be missed easily, since they have no speed margin to play with

    3. If you can see the F-35s, you are within the range of an AMRAAM (the AIM-120D/D+ btw), especially in a head-on engagement.

    if they use active ways to lock you, you’ll have their wherabouts long before you see them or even long before they get a lock (not to speak of being in range to fire).

    in the end, you’ll have one aircraft that can go supersonic over long distances “cruising” and the other that will be “flat out” to get to a similar speed…

    Basically, if you want to attack (which makes you a target for interceptors) you don’t want to get caught in a fight that’s not your mission…. being faster than the interceptors allows you to play with them and outrun them as needed to do your job…

    Pls read the above posts about the top speed nonsens.. RuAF Flankers or the Pak-Fa will never go at 2.0 M+ some 800nm from air-bases over sea..
    Unless they plan to use Norwegian Airbases to refuel:D
    Go figure why:rolleyes:

    Going at 2.0m+ for 15 minutes reduces Mission range considerably..

    Thanks

    ok, let’s see… the thing will supercruise to their ingress point, and since they have sort of “stealthiness” from forward quarter, your radars will eventually need some proximity to get a clear image of their whereabouts.

    Then, they’ll go towards their target, or, more likely, shift to a direction that may lure eventual interceptors (which, they know aren’t fast enough) to a flight pattern where they won’t be a nuisance for the PAK-FA mission….

    When these interceptors start getting closer, the atatckers can change course towards their real target, accelerate and leave the “would be interceptors” behind. Once the gap is sufficient to stay out of missiles range, they get back down to supercruise which is, basically, the F-35s top speed… staying simply out of reach.

    Now, explain to me how the F-35 will catch them. They won’t have to go Mach 2.5 all the time, just the time necessary to distance the pursuers and then, they can resume their “normal flight profile”, supercruising at speeds the F-35 will only reach if going full AB

    That assumes your target actually reaches its theoretical top speed, which is unlikely considering external stores and a low altitude ingress profile. How often do you think platforms actually reach M2 in combat with fuel constraints and a useful war load? M 1.6 is plenty. Any strike package will necessarily spend the vast majority of its sortie in the most fuel efficient flight profile, any supersonic sprint will be just that, a sprint. Its a 1500km+ flight from Murmansk to Narvik, even a Tu-22M would only use be supersonic for the very last part of the run. Unless you have an F-22A or a Pak Fa supersonic flight will only ever be in small sprints.

    Anyway the Norwegians are operating within NATO’s sensor footprint, so they will know whatโ€™s coming long before it gets there. Platforms can be pre positioned on intercept profiles given enough time. Therefore considering the pervasive nature of NATO ISR and the large ASM launch radius the critical element of an intercept flight would be its range.

    Top speed was the defining factor in third generation fighters; it hasnโ€™t been a definitive element of fighter design for 2 generations now.

    considering that the major (actually, the only) “threat” to norwegian airspace is Russia, and considering that they just unveiled the PAK-FA, they (the norwegians) have good chance of having to run after it in a decade or so… and be almost 1 Mach too slow…

    @ jackjack, the F-22 official top speed is classified, so the real speed it can reach probably won’t come to this board very soon… in any case, it’s above M2.0, that’s been officially stated… for the rest, we can only assume

    I think you’re stretching to make a point here. The KC-767 is already in service with Japan, and Italy will follow suit. The A330 does have more international orders at this point, but the idea of program risk being more of an issue for the KC-767 when it is actually in service is just not something I would nail down as a reason not to buy it.

    actually, if boeing proposes the saรนe tanker as for japan, one may say “it’s already in service”, but if they propose to their initial idea, one part from here, antoher from there, they build, indeed, a whole new aircraft which has to go through testing and all that.

    It appears they want now to do things simpler, but, still, we have to see their definitive proposal… and they wait to know whether EADS/NG does make theirs and how..

    If there’s no competition, they can propose more or less anything, and increase the price for following bathes to earn good money on it (under the scheme decided by the DoD, only the first batch or two can’t go beyond a previously fixed price, after that, boeing may be free to incfrease it at the only expense of the DoD.

    it’s one thing in peace time… intercepting an aircraft that’s cruising along, probing your defenses… but if you buy aircraft for war, you must be ready to run after guys who won’t just be droning lazily and wait ’till you get to them…

    you’ll have high speed, low altitude raids which you’ll notice when it will be already late.. and your fighters will have to go fast to get to the threat. An inteceptor that can’t go at a speed of its target needs lots of time before intercept, in order to position itself.. if you oponent wants to pass through and comes in fast, you can’t afford having 30% lower top speed than him… he’ll just deviate a little and you won’t be able to compensate..
