    Is it so outside the boble to say the F-22 has a better detailed signal management?
    Hell just take another example, those air spill doors from airduct on top of F-22 and then look at the ones on bottom of PakFa(Flanker) air-intakes.

    I’m sorry if it upsets people. It is what it is.
    I like the PakFa over F-22 Design for several reasons, stealth finesse is not one of them.

    I would say the F-22 is more boxy vs F-35 considering the F-35 has only one(huge) engine. And every airframe design is build around its engine/engines.

    Upset, who?
    When I sometime disagree with someone is not because I don’t appreciate him/her, right the contrary.
    This is a discussion thread so I use to reply to persons I feel worthy to, not with someone that say always the same thing like a broken record (absit iniuria verbo).
    The only one I get something upset is GarryA because it has this damn habit to take just one single phrase from my longer posts without reading all of it:angel::angel::angel:…

    And I call F-35 boxy because it so short that really resemble a carton box, or a brick:dev2:.
    A Su-24 has surely a even greater frontal area but is longer.

    Brillant.
    The level of discussion around the F35 have become sol low, thanks to the anti-trentacinque*, that we often overlook the most rational arguments 😡

    *What? She’s also an Italian airframe… Even dismissing all the grandsons and granddaughters of Italian immigrants 😀

    Tomcat, I don’t know know because it’s in my own language and not German, Swedish or French, also the latter one would be better employed for the opposite term, Ultratrentecinquistes meaning the numerous ones there that are more acritical supporter of F-35 than MoD itself.

    https://en.wikipedia.org/wiki/Ultra-royalist

    On my part, I always said that the F-35 is by far the better solution for what our own air force need i.e. a substitute for Tornado and AMX: it’s when they want to sell it out as a Caccia that I begin to LOL…

    Sigh..
    Let me try again. Being slim as the YF-23 and PakFa does not mean it has a lower RCS vs F-22.
    It only means it has a slimmer side profile, but LARGER top/under Profil.

    It a design choice.
    From ground or above the PakFa has a larger fotprint.

    To say it in Tomcat mode: anytime, anywhere.

    Oh and the same when PakFA turns over from a peer point of view.

    When ANY plane turns over the radar detection range istantainly fell down thanks to Doppler effect becoming negative.
    Hence the choice to privilegiate the frontal aspect.

    Yes, i’m sure Sukhoi want to cut some corners on cost, but that does not take away anything from the F-22 Design.
    It may be the most expensive fighter, but its a very advanced product. I’d say that matter.

    If the PakFa design advocates any advantage, i’d say it utilizing its internal volume a tad better vs F-22 more boxy airframe, and it also produce more lift from the blended wing/body layout.

    As you have said it, it’s a design choice.
    And the said choice have made the F-22 a terminated product.
    They will instead produce F-35 whose RCS reduction measues are not so extreme, so it seems it’s US MoD that wanted to cut corner of costs.
    And F-35 is boxy as the Nine Hells.

    Sorry to be so negative, your argumentation about design choice is substantially correct but also captious into demostrating A is better than B anyway.

    The USN, as per the F-35 SAR, is due to receive their last F-35s in 2031 and that is before we consider that an upgraded/modified F-35C is an option for F/A-XX. The USN will operate SH until probably the mid 2030s, makeing 34 years since IOC.

    Yes, but you wrote 2060…

    I don’t have launch weights available that can back up my claims, hence the use of the “likely”. What I will provide is F-18 NATOPS, which in Chapter 8 discusses launch weights and required power settings. https://info.publicintelligence.net/F18-EF-000.pdf
    If we look at operational use of the aircraft though, the only example of a light launch would be an airframe test. Every other profile can be launched with suitable weight to reduce the opportunity for oscillation and even an airframe test is an additional opportunity for training on the jet.

    Is there a single other mission profile that would result in a light launch?

    Global Security has some good info on emals here, http://www.globalsecurity.org/military/systems/ship/systems/emals.htm but the pertinent paragraph is probably below.

    Of the 10 Nimitz class in service 5 were built before 1990 with the Nimitz approaching 50 years in 2025 with each subsequent vessel every 4-5 years after that. Given F-35C won’t hit the fleet until 2019 and will be operated by the USN till at least 2060 it will almost certainly see more work on Ford class carriers than Nimitz.

    41 years, really? I know how airplane design take a lot of time actually but such a lifespan seem me absurd, it would be like the MiG-15 or F-84 to be still in service (in their original service branches, not in some third world country) in the nineties.
    It is true that actual 4gen fighters get an elongated life span but it was an exceptional situation due the end of Cold War, Soviet economy collapse and so called Peace Dividends in the West than a new standard.

    What are you talking about ?
    http://www.gripenblogs.com/Lists/Photos/F%C3%B6rsvarsmakten.jpg

    I WAS TALKING ABOUT the original A and B version, how you would have easily understood by the following phrase:
    At a certain point they developed a NATO compatible version, converted some of their originals to them and sold/leased them abroad with appreciable results (when compared with their previous models).

    P.s. Sorry for overreacting, Garry but being I a non english native speaker writing a post like mine last cost a lot of time and some efforts on my part, so contesting just a single aspect of it is a non starter.

    Hopsalot, countries are not stores, simply as that:
    they have this thing called internal market that made the difference.
    So you would find that USA are one of the greatest producer of both oil and gas than manufactured goods, just their internal comsumption of such products is so high that they have to resort into importation of both.
    On the other side nations like Norway having a comparative lesser oil production is still a great exporter of it because its own internal market doesn’t need more than a little fraction of it.
    In case of Russia production of oil and above all natural gas is so huge that it cover ad abundantiam the need of a quite large population .
    On strategical terms being an exporter of such products is quite the optimum if you want to build yourself great armed forces as they gave you a lot of money without having to spend it back on both machinery than workers wages as in the case of manufactured goods.
    It is because of that gulf states can spend so much on weapons and subsidize a great part of their own populations so to grant survival of their own deplorable regimes.
    Given that Russia actually not just produce but actually export a great deal of advanced weaponry, let’s figure it out how enviable its own position it on that regard.

    The point isn’t that it is somehow bad that Russia has lots of oil. The issue is that it doesn’t really have much of anything else.

    First thing: there is not absolute values of them, so this say nothing. Russia export more of what it imports, that’s is the important thing.
    Second:nations that are net exporter of manufactured product are very few and both France, United Kingdom and USA are NOT between them.
    Are them to be considered less advanced than China or S.Korea for that?
    So we have there nations that have both a net trade balance and are manufactured goods exporters, others that has just one of this two characteristics and others that have nothing of both.
    My own fall in the second of such category, in the quite unique position of being a manifactured good exporter but having a negative trade imbalance.
    Your own, gentlemen?

    Seem me this is a discussion with not much of any sense.
    Original Gripen and F-35 were designed from completely opposite starting point in terms of requisites and ecquipment.
    Swedish one was developed with a strict national defense perspective, limited range, NO AERIAL REFUEL, capability of take off from motorways and being manned by conscript, idea was to use the advance in electronics miniaturization to get the capabilities of the three different version of the Viggens into one, way smaller frame.
    They managed to achieve it, although with the limitation of using external pods for attack and reconoissance missions.
    At a certain point they developed a NATO compatible version, converted some of their originals to them and sold/leased them abroad with appreciable results (when compared with their previous models).
    Now they have introducted a complete revamp of it with the E/F version, most notable difference would be a greater fuel fraction, thanks to a new organization of inner spaces, a development similar to the one of MiG-35.
    And not without a reason as the concept that was underneath Gripen development (and generally of all the swedish fighters) was much more similar of those of former soviet Frontal aviation fighters, so similar would be also the way out from there into the actual needs: greater fuel fraction with not significant increase of empty weight.

    F-35 a.t.c. was conceived from the beginning as a long range strike plane with a fuel fraction unparalleled by other fighters (except the Mig-31).

    This, plus the need of carring its own weapons internally, lead to a very heavy plane with an empty weight akin to the F-4 and way more than F-16 or even F-15C.
    So, just really apples and oranges there.

    http://www.businessinsider.com/f35-pilot-f-35-can-excel-dogfighting-2017-1

    Interesting piece:

    Many have been expounding these points repeatedly on this forum. Here is a Marine pilot reiterating these points again. I’m sure the usual suspects will ignore, discredit with comments like: “Paid L-M shill” or “PR Memo”, and fire up that VHS of Maverick angling on Jester’s 6 secure in their logic.
    “Missiles don’t work, it’ll end up in a guns only dogfight”
    “Look at the F-4 in Vietnam! making the same mistake”
    “Sustain turn rate, John Boyd, Pierre Sprey”
    “Because wingloading… Wait the F-4 and F-22 have similar wingloading?”

    Seem me not adding anything really new: the idea that aerial combat is restricted to a cannon- range dogfight or a.t.c. a BVR frontal engagement at missile’s maximum range between two otherwise passive contenders moving on a straight line is a typical misconception running amok between both general public and armchair generals.
    Problem is that this false credence has been fueled through the past decades by the same ones that actually are trying to topple it.
    Before it was done to promote the idea of F-16 superiority against their opponent basing on the only flight parameter in which it really excelled, now instead they try to negate the utility of the same for selling out F-35 instead.
    Fact is that nor the soviet of cold war age neither, as it seems from what we see from Syria, today’s RuAF never had the same idea about aerial warfare and they so use a completely different set of tactics and countermeasures to the ones in the article.
    This article seems instead, like countless others I have seen before, focused into a close circle comparison between systems of wholedifferent generations but from the same side.
    So let’s begin talking about the situational awareness of the systems making the whole of actual Russia’s Ad network instead, please…

    I don’t think you’ve been following the US-India/US-Pakistan relationship very closely. A next gen fighter i.e. the F-35 is very much available to India, even if critical elements of ToT aren’t (read: AESA, ESM, EO systems, Fibremat etc).
    In terms of export, the Indian order is probably worth far more than all the rest put together (Algeria, Vietnam, Iran, Indonesia, Malaysia etc). In other markets, the PAK FA will be competing with the FC-31, if not the FC-20.
    But in general, I agree, paying $5-6 bn upfront for ‘development’ is senseless for what is a license assembly/production deal. It basically amounts to reimbursing Russia for its own R&D expenditure.

    The UK builds 10-15% by value of every F-35 produced worldwide. They’ve done very well for themselves.

    In India’s case, more than ToT, production work-share commensurate with its financial investment would the natural goal. Remains to be seen what they actually negotiate.

    So, you get F-35 frame without its avionics? It’s like to go in a three star restaurant and to order only the couvert and service IMHO.

    Probably Indian money went to russian developers to a further refination of the existing project in order to tune it for their specific need.

    Most important consequence would probabily be in the engine department with the introduction of the “intermediate”/early on engine before of the full capacity Objekt 30.

    I would wait until the -9 to -11 prototype to show off however: probably the first one would be the practical equivalent of what the russian sought before India jumped in and the successives would instead be indicative of the successive joint standard.

    This is probably the report you are mis-remembering…

    http://airheadsfly.com/2014/02/13/norwegian-f-16s-get-buts-kicked-over-iceland/

    Or it could be this one:

    It is in the second article that a Norwegian pilot states that all things held equal the Gripen can outmaneuver a Norwegian F-16 in WVR.

    Of course Norway’s F-16s are F-16As with the MLU update… now in the process of being retired…so I wouldn’t work from the assumption that the results would be the same against a current F-16.

    No, because the F-16A are actually considered more agile and maneouvreable than latest models, being lighter.
    The best was considered block 30, more powerful engine on a light frame while weight increase on block 40 & 50 reduced performances.

    Otomat missile comes in two version.

    French one dive high to get a preliminary look and after dive down, Italian one envisaged the use of an helicopter to made a mid-course update.

    Missile doesn’t need external guidance to operate however, on smaller ranges it function as all other sea skimming missile does.
    It was instead a way to compensate the target movements until the missile would have reached close enough to use its own radar, helicopter would so make just a brief popup, register target new position and correct missile course and dive down the radar horizon. again.
    AFAIK only Lybian 550 corvettes used Otomat without having provisions for an helo aboard, [I]Minerva[/] never had it.
