    Does it have a lower RCS than the Nighthawk?

    yes

    Can we intelligently speak about the ESM and ECM systems yet of a prototype only recently flying?

    yes, ECM systems work rather independently of the aircraft they happen to be flying on

    if it works on an F-18 it will work on an F-16 or an F-15 or an Su-27 (provided suitable integration work is done)

    Do we know to what level the RCS is going to be degraded for export versions of the F-35?

    they won’t be degraded

    http://www.dagbladet.no/nyheter/2006/05/01/464964.html

    > Will a version meant for the RNoAF (our airforce), recieve full stealth-abilities?

    YES….FULL Stealth!

    The FACT is this is in many ways a paper airplane until export spec items leave the production line.

    the F-35 is flying and is thus far from a paper airplane

    Well the USN is considering buying additional Super Hornets because JSF will not be available in numbers for a long time yet and no offence but they know just a bit more about what they are doing than you my friend!

    was i talking about the USN? no, no i wasn’t

    their situation is SLIGHTLY different than the UK’s

    the USN has TEN active supercarriers with an ELEVENTH coming online next year and has need for planes NOW

    also they currently operate the type so buying a few more now won’t jeopardize their ability to switch to the F-35 later, unlike the RN

    the CVFs won’t be ready till 2014 assuming no delays (haha)

    And no proven is not malarkey, proven means proven and that equals to a machine that does what it is built to do, the JSF has still to do that.

    proven by itself isn’t bad, but when you run out of convincing arguments and are reduced to ‘proven’, it’s time to give it up

    By your admission you said that F35B has made the sacrifice of fuel and payload so as to give it the STOVL ability and now you state it carries as much as the F22, but that is the land based and conventional carrier based models.

    yup, sometimes i do lose track of the train of thought :diablo:

    anyways, F-35B has 14000 lbs of fuel, which is as much as the CTOL SuperHornet

    I have posted facts and everyone else has not had to correct my posts because they are factual.

    you mean facts like “well the way things are going the JSF might jsut about start rolling of the production line in 30years.”? :rolleyes:

    facts like not thinking the F-35B will be able to carry any strike weapons internally?

    The F-35B has to pay the price to be stealth

    and if stealth is required, the Rafale will pay with its life

    and to stay in that stubby or draggy configuration always.

    you cannot just eyeball an aircraft and determine the aerodynamics

    We do not have any idea, how reduced the detection range of the F-35B will be in 2015 as we did not not about the Rafale.

    it will always be magnitudes of order harder to detect than the Rafale

    “Stealth” or reduction in detection range can be achieved in several ways. Even the F-35B has an EW-suit and will not stick to its passive stealth alone. 😉

    stealth is a tool and the US has never relied on it alone

    B-2s are accompanied by jamming support

    stealth and jamming are mutually supportive and make the other more effective

    stealth+jamming will always be more effective than no stealth+jamming

    well the way things are going the JSF might jsut about start rolling of the production line in 30years.

    it’s rolling off the production line TODAY

    The point of them being operational now is that the Rafale is a proven design.

    by that argument we should still be flying sopwith camels because they were ‘proven’

    the ‘proven’ argument is a bunch of malarkey from those who know their product will soon be obsolescent

    so the JSF is going to carry all these extra fuel tanks internally

    yes, in case you haven’t noticed, the F-35 carries an absolutely ginormous amount of fuel internally, more than an F-15C and as much as an F-22

    and take up the room of the ordanance, so what are you going to attack your enemy with???? oh also what about storm shadow, where are you going to mount this??

    the JASSM will be carried internally

    As for STOVL, it is a novelty, like TVC on some other fighters, its nice to have but not at the expense of range and weapons load as is the case here.

    that’s a decision for each country to make

    however, if they decide they do prefer conventional cat-and-trap, they can always go with the ‘proven’ (haha) superhornet or F-35C

    but then that leaves the Rafale, it is tried and tested in combat and fully carrier capable and IMHO would be a far better choice than the JSF for the new carriers.

    well a few problems with that

    1. would require the addition of cats and arresting gear to the carriers which is very expensive to do and expensive to operate

    2. the Rafale costs more than the F-35

    3. the Rafale costs more to operate than the F-35

    4. all the money would go to france as opposed to english companies like BAE and RR who make substantial chunks of the F-35

    5. the Rafale doesn’t have stealth

    6. the future of the Rafale is hazy while the F-35 will have a massive industrial base behind it driving upgrades for decades to come

    The JSF’s future is up in the air(pardon the pun)

    hardly, the US has no realistic alternative but to see it through and order 1000+ of them

    though the Rafale is operational right now

    ie it is older and more obsolescent

    production of the CVFs have hardly begun, what is the advantage of being operational now?

    in present day and will be operational for at least 30years

    operational for 30 years? lol, the F-35 will STILL BE IN PRODUCTION in 30 years

    besides the French will more than likely put their machines through 2 major upgrades.

    they need 2 major upgrades to even approach the sensor capabilities of the base F-35 (no AESA, no DAS, etc)

    plus being the mainstay of US forces, you can expect continual upgrades for at least 50 years

    The Rafale has a higher weapons payload than the B version of JSF that is to be flown from the carriers

    um yeah, that is the sacrifice you make for STOVL

    you can make the same argument in favor of ANY conventional carrier plane, like say the SuperHornet or even the F-35C

    and as for stealth as soon as you bolt on bombs, missiles, fuel tanks, stealth is right out the window anyway

    good thing the F-35B carries bombs, missiles and fuel tanks internally

    2. the Rafale costs more than the F-35

    What?? :confused:

    the F-35A was offered to canada for about 50 mill USD

    the Rafale has a flyaway (ie a foreign buyer will no way in hell get that) price of 65 mill USD

    the navalized version is 71 mill USD

    expect a similar cost jump from the F-35A to B

    The final value of the second sale is not yet determined, AFAIK – again, it refers to “a possible Foreign Military Sale” & says “The total value, if all options are exercised, could be as high as $1.5 billion”. As with the first sale, the price in the US DSCA statement is the maximum possible, not necessarily what will be paid.

    Now, what was that about “case closed”?

    let me quote from the Israeli F-35 sale notice (http://www.dsca.mil/PressReleases/36-b/2008/Israel_08-83.pdf):

    The total value, if all options are exercised, could be as high as $15.2 billion

    sound familiar?

    Sens was saying the F-35 was too expensive, because wow! just look at the Israel deal, $203 million/plane!

    yet if we look at a plane that is universally acknowledged to be cheap, it has practically the SAME price when part of a similarly structured deal

    the take-home point is that the F-35 is not significantly more expensive than other 4th gen fighters (and is in fact cheaper than many)

    so all this whining about how expensive the F-35 is, is just BS

    Initial buy: $3.1 billion
    http://www.dsca.mil/PressReleases/36-b/2007/Australia_07-13.pdf

    Follow-On support: $1.5 billion
    http://www.dsca.mil/PressReleases/36-b/2008/Australia_08-80.pdf

    guess what! that’s already $4.6 billion, just from those 2, which is MORE than the $4.2 billion i said initially

    case CLOSED

    $4.6 bln USD = $191.6 mln/plane, which means the Israeli F-35 deal is less than 6% more expensive than the SooperSnornet

    F-35 is looking better all the time 😀

    Didn’t you notice something in that quote? “over ten years“.

    yes, it means they aren’t signing 1 contract, but several smaller contracts that are spread out over time

    as it said,

    Additional cases will be established later this year for weapons acquisition and sustainment of the aircraft.

    clearly these are ACQUISITION costs because they certainly aren’t OPERATING anything in 2007

    pilot training doesn’t begin till 2009, and the first 4 aren’t to be delivered till 2010

    It’s clear from the context that A$6 bn includes all costs (including infrastructure, operating costs, etc) in a ten year period

    no it’s clear from the context that it means exactly what it says: “acquisition and all support costs as well as personnel” (personnel refers to training costs in case you were confused)

    notice that it does NOT say “operating costs” anywhere in there

    if the $6 billion included all operating costs, they would have said ‘all operating costs’

    but they did not say it because that’s not what it is

    i’ll make this simple for you: find one official source that says the $6 billion includes fuel

    you won’t find it

    Which we know isn’t the cost of buying the aircraft, or even the cost of the aircraft plus a fat package of support, spares, weapons, etc., but all of that plus an estimate of operating cost over 10 years.

    what we all know is that you’re wrong

    the 6 billion is ACQUISITION cost, not operating cost

    that does not include fuel, that does not include pilot hours, etc

    http://www.minister.defence.gov.au/NelsonMintpl.cfm?CurrentId=6437

    At a cost of approximately $6 billion over 10 years, the acquisition of the Super Hornet will ensure the transition to the F-35 Joint Strike Fighter over the next decade.

    The acquisition will include 24 aircraft, initial support and upfront training for aircrew and maintenance personnel.

    . . . .

    How has the Super Hornet acquisition been funded?

    * The acquisition of 24 Super Hornets will cost approximately $6B over 10 years (2007/8 – 2016/17)
    * This includes the cost of the aircraft, weapons and associated supporting infrastructure.

    Even the USAF is in need to buy the support train of its shiny new fighter

    which is going to be true for any program

    let us examine the Australian SuperHornet deal

    http://www.abc.net.au/news/opinion/items/200703/s1864837.htm

    24 for $6 billion AUD = $4.2 billion USD = $175 mill/plane

    the Israeli deal:
    75 for $15.2 billion = $203 mill/plane

    so in worst case, the F-35 is 16% more than the supercheap superhornet

    (remeber Boeing offered the SH to the USN for $50 mill a pop if they agreed to a multiyear deal)

    is the F-35 16% better than the SH? easily

    and remember the SH is from a very mature product line that won’t get any cheaper while the Israeli F-35s are being pushed forward as soon as possible, so later planes should cost less

    we don’t know that the 2 packages are exactly comparable, but it should give some idea of how overall program costs work

    I havent been follwong Chinese development so i cant comment whether Stealth is important or not. But For Sukhoi has said Stealth is one of criteria among so many for there 5th generation fighter.

    so there you have, Sukhoi believes stealth is important

    unlike you who keep claiming it is already obsolete

    if it was already obsolete, why bother incorporating it?

    They are testing EW systems.

    again, the EW systems of the US are DIFFERENT than those of Russia, so testing it against flankers tells you nothing

    Russian have clearly seen F-22. and can accurately predict where its RCS will lie.

    if it’s so easy to predict from pictures, then why is radar signature still so so classified?

    something tells me pictures don’t tell the whole story . . .

    just like they preidicted so many other things.

    like how they predicted the F-14 was a Mach 3 super plane?

    next 20 years? It is next 5 years.

    then there should be an abundance of sources on this magical nano

    i’m still waiting for 1 . . .

    Stealth is good against 1970s radars.

    it is

    it is also good against 2008 radars

    Sukhoi believes in it.

    funny, their promo videos for the Su-35 show it firing missiles, not guns

    http://www.youtube.com/watch?v=hpgMH92jieg

    I can see the difference. F-22 is much costly project with same one role as single role of F-117. F-117 was not even produced in greater quantites nor was computing and manufacturing technology that advanced in F-117 time. It was much more difficult project to execute.

    exactly, disproving your point that stealth hasn’t advanced in 40 years, which is obviously false

    So it works against one kind of system does not mean it can work against some one else systems. Just looks at high tech manufacturers of semiconductors from Japan/Korea/Germany. there is difference.

    the laws of physics don’t change

    it doesn’t depend on a particular implementation (as your beloved EW does)

    there is a reason x-band was chosen for radar that tracks aerial targets: it works the best

    F-35/F-22 stealth ‘defeats’ x-band radar, period

    to get around it, you have to switch to different wavelengths which don’t work as well and have significant limitations or you have to use multiple transmitters/receivers, which again has its own difficulties

    F-35 needs all the fuel because of its weight and stronger engine.

    it weighs less and has less thrust than a flanker, so again, wtf are you talking about

    Without Stealth there is nothing special about F-35 that any other 4th generaton fighter cannot upgraded.

    but it does have stealth, and no matter how much you massage it, no flanker will ever have it

    Flanker can be upgraded with airlaunched Klubir/Brahmos and Strike mission will still be cheaper than overall cost of maintaining and buying F-35.

    again assuming they ever get close enough to launch

    but wait! didn’t you just say all missiles will be obsolete!?!

    if missiles are obsolete and it has to drop bombs directly over the target, what then?

    So does the cost of building F-35. It is still way more than legacy fighters.

    wrong again

    http://www.canada.com/vancouversun/news/story.html?id=65945a64-3c5f-46a1-96f6-ced8e3b4972d

    a deal that would see the price of each aircraft ordered set at around $50 million US

    Stealth make the project alot more expensive to beging with and increases multiply with production cuts.

    how much of the F-35 budget was devoted to stealth? do tell . . .

    Provided those limited quantities of weopons can saturate Ship defences and have kinetic energy to do so. There is reason for going towards hypersonics.

    i’m really not sure what you’re whining about, the F-22 and F-35 can carry as many weapons as any other 4th gen plane. If the US develops a hypersonic missile, they could carry that. That is a separate issue and is not a limitation of either the F-22 or the F-35

    JSF consumes more fuel as it is heavy for single engine fighter. 4th generation fighters are cheaper to procure and can carry longer range weopons so no need for the same mission profile.

    JSF consumes less fuel than dual engines fighters, like say the flanker for instance

    we’ve already shown that 4th gen are NOT cheaper to procure

    and what in the world is your thing about older planes being able to carry longer range munitions than newer planes?

    it makes no sense and is flat out wrong, the F-22 and F-35 could be adapted to carry anything an older plane could

    I havent read anywhere that PAK-FA is 5th generation because of Stealth. It is one of the several criterias.

    let me recap the conversation for you since you seem confused

    you: radars will negate whatever little advantage stealth has
    scooter: yet russia/india/china are developing stealth aircraft (which seems to indicate they don’t believe stealth will be obsolete)
    you: iskander/smerch/5th gen mobile air defenses are their top priority
    me: yet they continue to invest in soon to be obsolete stealth (again indicating that they believe it will be useful well into the future)
    you: stealth isn’t required for 5th generation (completely avoiding the point)
    me: PAK-FA and J-XX are both designed to be stealthy, thus BOTH THE RUSSIANS AND THE CHINESE BELIEVE STEALTH IS AND WILL BE IMPORTANT
    you: more COMPLETELY avoiding the point that BOTH THE RUSSIANS AND THE CHINESE BELIEVE STEALTH IS AND WILL BE IMPORTANT

    It can assumed that Russian tests Flankers and Fullbacks against there own airdefence system.

    lol, because flankers and fullbacks simulate stealthy F-22s and F-35s so well

    and u dont need actual stealth plane to test radar technologies. any RCS models can do the job

    but do they have an accurate rcs model of either the F-22 or F-35? their actual radar signatures are classified . . .

    I think that Nano technology revolution have passed on way side of you.

    woah there partner! now you’re starting to wander off the reservation

    nano? really? nano what?

    please point me to some references about magical ‘nano’ that will be fielded within the next 20 years

    Thats ur assumption that Stealth cannot be seen. One Russian designer got state prize for developing radar for detecting Stealth and that was a decade ago.

    stealth never meant invisible, it meant harder to detect, it meant reduced detection range, it meant less accurate tracking

    those still hold true today, no matter how many awards russia hands out

    When EW suites based on nano technologies make missiles obsolet than u have to come to gun fight there hypermanevorablity with massive acceleration comes into play.

    LOLOLOLOL

    EW (with magic nano technology) will render ALL missiles obsolete and thus we’ll be back to the days of the Red Baron 😮

    i’m sorry, if you really believe that, there is nothing i can do to help you

    Because Stealth design is fixed for 4 decades.

    absolutely false, if you can’t see the difference between the F-117 and the F-22 you’re blind

    they’re always advancing the art and the new 2018 bomber is supposed to incorporate long-wave stealth too

    U cannot do much more with already built plane. EW/Radars are continous upgrades year after year provided the right funding.

    true the radar signature of the F-35 will probably not change/improve much from this point, BUT it works as it is designed to and works well

    to detect it requires new wavelengths that aren’t as effective and big antennas that don’t fit on planes or missiles

    Its relative term. Steatlh planes are heavy, can carry limited amount of fuel and weopons for its size, price and maintainability is way higher. aerodynamic compromises are another things.

    because the F-22 is so aerodynamically compromised :rolleyes:

    limited amount of fuel? are you kidding me? the F-35 has the highest fuel fraction of any modern fighter

    limited weapons? the F-35 can carry as much as an A-10. obviously not in stealth mode, but it gives you FLEXIBILITY

    if stealth is important, the F-35 can carry 8 SDBs
    if stealth is important, it doesn’t matter how much the Flanker carries because it never makes it to the target

    stealth does require more maintenance, but there have been dramatic improvements in making it easier. The difference between the B-2 and the F-35 is night and way

    wow a defense project went overbudget, first time that’s ever happened

    We are living in different times. World has changed. U cannot do what same what was ok in past

    right, so we just eliminate stealth and suddenly all projects will be on time and on budget and will run on unicorn farts, just like the FCS, C5-M, LCS and practically every other military project that doesn’t involve stealth

    oh wait . . .

    stealth is NOT what’s delaying the F-35 program. the engine didn’t like hover mode, DAS hasn’t been finished yet, there are still millions of lines of software to write and integration issues to test, the thermal management in hover mode is challenging

    stealth doesn’t even rate a mention at this point of issues causing problems

    I guess u cannot see the limited role of F-22. u cannot sink a ship with the amount of weopons F-22 carry nor it can do ASW job.
    one of Criteria of PAK-FA is multirole for all roles.

    that is not an inherent limitation of the F-22, it’s just an integration issue

    they have other planes to do ASW work so it makes sense to focus the F-22 more on what it does best: A2A combat

    if the need arose, rest assured they could hang a couple harpoons or JSMs from it

    that said, a couple 1000lb JDAMs could ruin any ship’s day

    again, it won’t be the first military project to be over budget and behind schedule, and it won’t be the last

    Surely u can continue on this path.

    surely we can and we will, we’ve been doing it for 200+ years, no reason to change now 😉

    When Stealth become obsolete than whats the point of high price of JSF with massive amount of fuel. Can u predict fuel prices in 2015?

    um, whatever the price of fuel is, the JSF will be more efficient than it’s contemporaries who will have to carry draggy external tanks everywhere they go

    We are living in 21st Century. Where there is massive improvement in Airdefence/Antiship/Space based technologies. U need aircraft carrier of 300 to 400 aircraft to fight first rate power not some thing based on past.

    that has to be the funniest thing you’ve said so far
