    Even the Russian fanboys do not claim such nonsense. 😮
    The US defence ministry does have all data at hand. 😎

    I use the word we, when referring to us here on the forum, relying on open source info/speculation. I’m sure LM/USAF knows what the F-22 can really do, and have a pretty good idea what the F-35 will do.

    Here the lighter F-16A has the adavantage too. The heavier F-16C were in need to relax stability again by more control area. I will hope you missed my post before otherwise you are resistant to facts. :rolleyes:

    And below the basics.

    http://en.wikipedia.org/wiki/Lift-to-drag_ratio

    With a faster true airspeed the radius of turn is dramatically larger, and with a slower true airspeed the radius is dramatically smaller.

    I was pointing out that with the high thrust, maintaining airspeed(lift) would be easier vs. bleeding energy(or going fast with a bigger turn radius).

    Excellent summary…………..:D

    Why thank you.:cool:

    It comes down to how you weight the respective strengths and weaknesses, to get the best idea of what the real world performance will look like.

    None did deny that. One side of the coin (=F-16) is a plus in installed thrust, when on the other side the underlined ones are in minus.

    A highly unstable aircraft can perform maneuvers that a stable aircraft with a lower wing loading can’t do. Available thrust(dry or wet) keeps airspeed up(which in turn helps maintain lift).

    For the f-35 i would say that, but for the 22 that is the oldest blatant excuse to say “hey..it can do more” ;), is like when the f-117’s are caught on the radar screens far, far away and then the ppl say “ahh is that because it was not on stealthy mode” 😀

    Come on..

    The F-22 has only been in service going on 3yrs now, and much of its capabilities are still highly classified(even F-15/F-16s have aspects that are highly classified, and they’ve been around a long time). Where am I incorrect in my statement. By the way, what range was the F-117 detected?

    All points well taken and I thank you for them, however all I was trying to do was to reply to Over G who was stating that the F-16 was a bomb truck. It was not designed as such. The F-35 to me looks like it has been built around the air to ground scenario first and the (notwithstanding considerable) air to air capabilities are secondary in that philosophy. Wing area, relatively poor rearward visibility and apparent g-limitations on the “C” variant all tell me that the designers did not start out thinking about air to air first. Typhoon simply put was.

    Which is the better obviously remains to be seen.

    Cheers

    As for the rearward visibility, the DAS/ESM should adress that, in terms of situational awareness. Granted, if one does find themselves in a furball, it’s nice to have good visibility. As for the C variant- it’s supposed to have very good low speed handling/turning performance. There’s also the notion of prolonging airframe life, considering the additional stresses carrier operations cause. The thing to bear in mind though- you can still have a tight turn radius, even if you’re not pulling 9gs to do it(i.e. A-10, F-18).

    Wrong, when it is the same basic design and physics can not be cheated.
    By the way a typical behavior, wishful thinking on and common sense out. 😀

    Available thrust/lift, airframe instability also play a big role in agility.

    Let the fanboys skewer me on this one but there is no way a glorified bomb truck like the F-35 will ever be the dogfighter the Typhoon can be.

    You’re not looking at the 2 aircraft as weapon systems though. The Typhoon may enjoy some WVR advantages, but….the F-35 is less likely to have to get into the WVR fight(which isn’t where you want to be anyhow). You’re also not taking into account how effective weapons/sensors are against a (more)conventional airframe vs. a VLO one. The F-35 is still more likely to have the element of surprise whether BVR or WVR, which is a huge advantage. That combined with a still very maneuverable airframe, HMS and HOBS missiles.
    The question then becomes- does the % advantage the Typhoon might have in WVR offset its disadvantages? The F-35 is most always going to enjoy first look, first shoot advantages over the Typhoon, and a greater ability to hide. Those are pretty important capabilities that shouldn’t be dismissed.

    What do you claim a common sense is your guessing to stay polite.
    Sofar I never red an official claim about the supercruise capabilities of the F-22A.
    It is Mach 1,5+, but not related height (=atmospheric conditions) nor the related flight-time is given. At the demanded mission profile it is ~200 nm in super cruise or ~13 minutes.
    To do so, the F-22A has a special inlet-system and outlet-system for supersonic speeds. To overcome the “hill” of drag in the transonic region in the most fuel economic way, the F-22A will use the burner. 😉
    But everyone is free to enlight us with the related links. 🙂
    See about inlet-system:
    http://www.patentstorm.us/patents/5779189/description.html

    The problem is that all those #s and specs are ~, and assume that the true capabilities are only at or below the requirements. Even if we assume the ~200nm/13 min supercruise range, how does that compare with 4th Gen fighters at similar speeds? The true figures are all classified, so everything else is speculation(be it optimistic or pessimistic).

    Could a Typhoon intercept and destroy a Su-34?

    Could a F-35 survive an intercept by a Su-27/35 or Mig-31?

    Yes, and yes. What are you asking?

    Your are guessing around in a fanboy manner. The F-35 has just reached Mach 1,05. Neither LM nor the USAF did claim some kind of super cruise. :rolleyes:
    The range data given for the F-35 are a real disappointment. To be in clean configuration does become a new meaning for the related drag by the F-35A.
    2.225 km by 8.382 kg internal fuel
    :diablo:

    LM and the USAF are also trying to sell/get more Raptors, so it’s not an unreasonable idea, that they may not be hyping all of the F-35’s capabilities.
    As for the range/speed data- those figures were the minimum requirements, but do we know unequivocally that the F-35 doesn’t exceed them?

    Obviously the Typhoon is the better aircraft for all aspects of air to air combat – isn’t this obvious? The acceleration of the F-35 will never compete surely?

    It’s not obvious, which is why there is discussion. There are areas where each aircraft has advantages. The question is which advantages are most important in current/future air combat.

    I know the F-35 carries it’s weapons internally but the trade off for this is that you have increased drag when those bays are empty.

    Right now we only have the opinions of the test pilots to go by, and they’re saying the plane accelerates/climbs rapidly, and handles very well. That would tend to make me think that the internal weapons carriage doesn’t give a very large drag penalty to the F35.

    For the F-35 it is not even an hearsay.
    25 NOV 08 – Pratt & Whitney’s F135 Successfully Completes First Supersonic Flight
    Pratt & Whitney’s F135 engine successfully completed its first supersonic flight, reaching a top speed of Mach 1.05… 😀

    How does this demonstrate anything? There’s no info given on whether afterburners were needed to reach that speed. That’s certainly not the top speed of the aircraft, just the top speed they reached on the first supersonic test flight.

    The PAK-FA project has long since been funded. Awesome Russophobic analysis from you once again. :rolleyes:

    As opposed to a Realismphobic analysis.:cool:

    To try and give you one example. How come a typhoon with a sinlge tank, 4 amraam, 2 asraam can SC up to mach 1.3 and a clean F-35 appreantly cannot. (the typhoon is not clean here btw :rolleyes:)

    We don’t know what the F-35 can or can’t do yet. It hasn’t even finished its flight testing yet.
