    It would be more useful simply to compare un-refuelled combt radius, rather than including range.

    Every combat aircraft needs to be capable of performing a mission. Combat radius shows in a simplistic way, without taking into account such variables as weather conditions, flight profiles, altitudes flown at, varying climb rates (high readiness alert missions etc) nor weapons/sensor loads, specifically.

    Range is simply a metric of how far an aircraft can fly, not a usefulnumber as to how far an aircraft can go and fight… If you wish to compare military aircraft in such a way, despite the futility of such, as I’ve just described with SO many variables that HAVE to be considered, then official, open source information on combat radius, is the best to use, IMHO…

    How about Eurofighter front sector comparison with a single centerline tank and the 4 semi-recessed Meteor? All else clean. Still no? Close?

    We were discussing frontal cross section, not performance or capabilities. But if we are going to be fair, then you should have the same basic capabilities between the aircraft and add an eternal EO/IR sensor plus it’s pylon as well. I believe the Typhoon uses the Litening and to have anywhere near the same range performance, the Tiffy needs 3x drop tanks…

    The numbers go into a dive EXTREMELY quickly when you start talking about jets in a combat configuration as opposed to clean…

    As for your mythical F-16XL, I’m not even sure why you mentioned it? It doesn’t and won’t ever exist. The closest you’ll get is something like this:

    care to keep discussing draggy airframes?

    pfcem, wrightwing or sferrin would most likely disagree with you 🙂 Then definitely can do it 🙂

    Don’t forget Carlo Kopp…

    He can even do it when looking at non-production representative aeroshells….

    considering the “front section”, according to these drawings, simply through a area measurement in photoshop it comes out that:

    Typhoon has 11% less frontal surface
    Rafale has 7% less frontal surface
    Super Hornet has 25% more frontal surface.

    however, if you’re to measure the frontal surface of an aircraft for what counts (transonic area rule), I doubt that the F-35 will be very happy with that.. it’s easy to see that there’s no section reduction at the wings section, which means it has a pretty nasty “peak” that will increase its drag in transonic.. it will overcome that drag through high thrust, but that means it will gulp fuel as if there was no tomorrow…

    basically, it has to stay subsonic

    Just fuselage, or did you include the wings too? 🙂

    However to be somewhat accurate and realistic, why don’t you add weapons, pylons, fuel tanks and EO/IR sensors to those cross sections and run the figures again?

    All variants of the F-35 can fight in that front sector configuration. Not one of the other fighters can go into combat like that…

    Comodord, I’ll see your legacy Hornet and raise you an F/A-18F Shornet with 11x Mk 83’s and a pair of AIM-9X’s…

    It is a bit of a trick to compare F35 and Rafale front profile actually. If you look at the side profile, the Rafale canopy sits on top of the fuselage, and it iself tapers all the way to the back.
    The F35 however has a hunchback profile all the way back to somewhere between the tails, where it tapers abruptly. If you look at LM video of the plane they allways hide this detail, to make it look less ugly/bulky.

    So the F35 is far from a teardrop design. This may matter less in the supersonic regime, as there are other factors that come into play.

    My guess howerver is that the F35 will be less of a player in sustained turning.

    Please show exactly what you are referring to. Here are the side on views you requested.

    You’re not perchance referring to the F-35B are you?

    I’m not sure what you are referring to about L-M “hiding” side on profiles of production representative airframes. There are literally hundreds of photos out there, from EVERY angle…

    Just one shot, side on is all that is needed however…

    It is called volume efficiency – the F-35 takes up close to the same space (length, span & frontal cross section) as the Rafale but fits a lot more within that space. I am not saying that the F-35 is not ‘daggier’ than the Rafale but there are quite a lot of people in making their ignorant ‘estimations’ as to the F-35’s drag are actually thinking it is larger than it really is. It is obviously ‘bulky’ but bulk in and of itself does not create a lot of drag…

    Super Hornet, Rafale and Eurofighter all have to fit 2 engines inside their airframe, whereas F-35 only has to manage one…

    Which aircraft would this be…is the J-17 designed to operate of highways? I did not know this was an operational requirement of the PAF just like some European nations.

    F-16’s can do it as well, as Singapore has proven with it’s RSAF Exercise Torrent series. I believe 2008 wasthe most recent serial for this…

    Don’t you need more than a pair of EF-18G to realistically replace the capability of one EA-6B? One limitation people don’t seem to grasp with the EA-6B role is it’s not just the number of jammers, its also the number of technicians in the seats that matter. It would have been more cost-effective to overhaul the EA-6B to fly another 6,000 hours! That’s not even dealing with the overhead cost of keeping them on station at the distances a strike package operates! They really needed to get a bigger airframe than the Super Hornet for the role.

    How many EA-6B’s does Australia need to replace?

    :confused:

    Australia should cancel JSF and opt for More FA18E/F and acquire Growlers. Say 50/50 ratio of E/F to G model. Say 40 E/F and 40 Growlers would be enough to see us to 2030 and beyond.

    We don’t need 40x Growlers, that is quite a ridiculous figure. In a strike package, you might have one or two Growlers at most. Your force structure would see strike packages comprised of 50% Growlers. They’d jam absolutely everything alright, (including perhaps, each other) but you’d have few aircraft to actually conduct any striking let alone conduct air defence, CAS, maritime strike taskings etc, etc…

    The USN, last I heard, had 90x Growlers on order to support (I think) a fleet of around 28 fighter squadrons, plus USMC and USAF missions.

    RAAF has 4x fighter squadrons in total…

    A more realistic mix, would be 72x F/A-18E/F to provide 3x operational fighter squadrons, an OCU and training and development aircraft, PLUS an Electronic Warfare Squadron equipped with the 12x F model’s we are having pre-wired for Growler conversion, with the conversion taking place down the track, assuming the full Growler capability is even cleared through ITARS, which has not happened yet, AFAIK…

    This would allow RAAF to structure force packages with their own AEA capability and a dedicated SEAD/DEAD whilst not compromising RAAF’s ability to conduct it’s normal taskings…

    Uh… Except Sweden can, and could probably turn a profit off leasing fully supported Gripens at the maintenance cost of Block 20 F-16s, whose support infrastructure isn’t included in that lovely “free” price. Regardless of the merits you suppose, they weren’t given a chance to present their best offer because Romanian MinDef didn’t make an open RFP.

    Didn’t Romania send out an RFI some years ago? The American’s announced the free F-16 platforms in their DSCA announcement in 2008. Are you honestly going to argue that nearly 2 years is not long enough for SAAB to realise that if a competitor is offering a free platform for the initial stages of a contract all the way back then, then perhaps they’d better update their proposals to match?

    As to your other ideas, will Sweden provide an upgrade to base infrastructure, air traffic control systems, the physical strutures for maintenance, support and training facilities for free as well or in reality, will Romania have to pay for this stuff irrespective of which fighter is chosen?

    Instead of having a massive whinge, when an opportunity is lost, perhaps they’d be better off concentrating on making the best offer in the first place…

    So Romania didn’t even try to look at

    1) second-hand Swedish Gripen A/Bs and an option to then in the future go for Gripen NGs just because Hungary uses Gripens ??

    2) second-hand Typhoons that some Typhoon user may want to off-load like the Luftwaffe ?

    at least a modicum of a competition would’ve benefited them with the US offering better terms and maybe even some offsets..seems like Romania wants to cuddle real tight with the US.

    Or Sweden and the Eurofighter consortium simply couldn’t match “free” airframes…

    Ten years & four months in RAF service so far, & intensively used ever since.

    Out of interest, I have no idea of the respective usage rates, BUT

    RAAF’s have been used intensively as well, for a similar period of time as the RAF and have a planned LoT of 2030…

    Just thought I’d add that in there…

    The source was WSJ, but it doesn’t really matter as long as LM denies the whole thing. Whoever makes such a claim has to provide proof.

    Lockheed says F-35 classified data not breached

    It’s amusing that critics bash the F-35 program for being so far behind and having so much code still to be written and proven and then turn around and lambast L-M for having their code “stolen” by the Chinese…

    Has it been written yet or not?
