    we brought spanish ships
    we brought french helicopters
    we brought yanki fighters, as most of the phoon partners have
    hard to throw mud on aussies ..its just the fact that usa leads in fast jets

    sintra said Someone should learn maths…
    R&D etc puts the rafale about 300 mil from what i was told here, do you have better numbers ?

    as i see it and have said, a 1% gdp by each eu nation for a joint R&D euro plane is the only answer i can see, but getting the agreements is another thing, as everyone wants to look after their backyard and not the eu as a whole, this is where usa beats you

    Good to hear that you found the link interesting. πŸ™‚

    Similar surfaces can be made much thinner- the absorber in this case used a grid of PIN diodes as a frequency selective surface sandwiched between two conductive layer, forming an adaptive Salisbury screen. Other fss materials can be much thinner- simple conductive repetitive patterns, i.e. a grid or mesh can be thinner. These types of absorbers are called circuit analog absorbers.

    Absorber performance for these types (particularly active types where a voltage is applied to FSS layer) is very good. However, one downside is that the voltage must be actively controlled to ensure best performance over a broad range of frequencies (for active types at least, not passive types). This doesn’t seem like a large issue to me, as it doesn’t need to be exact and a rough frequency estimate would probably work fine, and when shaping comes into play, slightly degraded absorber performance probably is not a huge issue.

    I would say that it is likely that the F-35 uses this technology in its skin for an absorber, though as Lindermeyer says, it may more likely be a means for dealing with lightning or other atmospheric electrical effects.

    even though it dosent have mega volts and pretty sparks making plasma
    your suggestion or similar is the one i find matches what would be desirable

    this should be the only sentence the euro partners care about, as their R&D costs are fully paid in the original agreement
    none are getting the f-35c, 35b and italy’s 35a costs should be broken down from the group price
    i read the f-35a is about $65 mil, i dont know what the f-35b is going to be

    “The production cost alone of each plane is estimated at $92.4 million, almost 85 percent higher than the $50 million projected when the program began in 2002, the Pentagon will tell Congress.”

    In theory, Turkey might be able to do that for Mavi Marmara. She’s a NATO-owned, NATO-registered ship, crewed by NATO citizens, & was in waters covered by the NATO treaty.

    it was acting legally on the high sea, if it entered 12 ml it would have been different
    turkey is nato member, is it an illegal attack against nato ?
    if nato includes merchant shipping being attacked by a state
    what could be more significant is if it triggers any nato agreements, or was turkey acting outside of nato

    If you think that only the supposed best nations are working on AC , one should look at what Brazil has been doing since 2007 :

    Nice “eye opener” isn ‘it πŸ˜‰

    Cheers .

    no i’m use to you now, very little is an “eye opener”
    its just another example of your inability to understand what you are reading or what we are talking about
    or you think we are talking about how it lets you see things more clearly

    my mistake and i added the content of it to my last post
    i will reply to a couple of your posts about articles later when i get the quotes and say as to the reasons why i find it improbable even for 5t
    development using the rafale as a test bed for use in 6th gen if the hardware architecture can be added as a stand alone in the rafale

    fanboys in english multinational, googling in french isnt my forte

    repost
    what i said was totally accurate
    up until the A&R article, many fanboys have been saying for years that the rafale had AC
    since the article most have back peddled to a position that it will have soon

    google can settle whether fanboys said since 1997 that rafale had spectra AC, how many examples would you like ?
    5, 10, 25, 50 or more ?

    I have no reason to doubt that THALES etc are investigating active cancellation, (and probably others to).

    I think the distinction has to be drawn between investigating and will be on the Rafale F4 in 2012 type claims (random figures). This I suspect is where most of the arguments originate.

    thales do the active cancellation on french subs, i dont think anyone would argue with that statement

    the dispute has been going since 1997? when bill didnt get his question answered
    making rafale the only aircraft in the world to have AC, according to fanboys
    they say the b2 didnt, that was usa most likely platform to have it at the time

    That’s correct. The Jane’s Missiles & Rockets article I referred to showed a mockup of a proposed steath cruise missile.

    But neither the Aviation Week or Jane’s Missiles & Rockets were written by Sweetman, but by the “Two Dougs” of UK defence journalism – Doug Barrie and Doug Richardson respectively.

    i’m not questioning mbda work in AC it is well documented
    i’m questioning the thales/mbda joint venture AC for rafale claim by bill
    with BAE saying thats ok give thales our mbda tech on ac

    just for a talk, and in between the banter
    i think
    mbda ac would be used against low frq early warning radar, if they can get it to work, higher x band is multiple times harder
    thales spectra and mbda are at opposites in outcome,
    mbda is attack, thales is defense,
    mbda is low band, thales is higher x band,
    mbda is going to use it on VLO cruise missile, thales is going to use it on a 4th gen air frame
    hence another reason for the unlikely joint venture, it would really serve no purpose and get in each others way, even if the parent companies agreed, which i cant see BAE giving it agreement

    arthuro
    do you mean other than concluding from not answering a question proves rafale has AC ?

    an unsubstantiated claim that thales and mbda are working a joint venture for AC for rafale ?
    with the parent companies just saying thats ok, we dont mind giving you our IP
    BAE dont want to use AC on thier planes if mbda can get it to work ?
    the fact is there is more of a chance that bae has it on the typhoon, that dassault has it on the rafale

    “a good knowledge of AC program in france”

    i doubt that very much
    frances AC program for subs isnt made public, which is the more the use of it

    I’ve already cited two sources – Aviation Week and Jane’s Missiles & Rockets. But I consulted both in paper form. The on-line archives of both magazines are probably available only to subscribers.

    here is another,
    http://www.defenseindustrydaily.com/Frances-Rafale-Fighters-Au-Courant-in-Time-05991/
    MBDA and Thales have since confirmed that they are working on active cancellation for missiles as part of the Rafale’s SPECTRA defensive …
    but they are using bill’s article as the source, as i think you may find with yours

    my understanding is mbda was experimenting with AC to use with their cruise missiles
    the thales/mbda spectra is that mbda provide the flair decoy system and such

    but a&c didnt mention AC
    you dont think BAE, EADS and Finmeccanica would have an interest in protecting MBDA intellectual property [IP] a clear MOU would have been written if there is any truth in it at all, as you are supporting bills claim, it really is up to you to back it up in the first instance, which i am happy to assist you by sending emails if needed

    another question would be what division of thales was allowed access to mbda, the obvious one would be ‘thales usa’ who makes the jammer for rafale and they are firewalled as is ‘thales australia’

    you seem to be saying if bill said it, it must be true
    no wonder you dont question the AC claim

    ps
    just to keep you updated, so far LM hasnt answered my questions , so far this confirms that the f-35 has plasma and ET tech

    2 which stuck out
    optical missile-launch-warning system,
    there was a release this year that rafale is getting an optical system
    the picture i saw of the AC test bed aircraft wasnt a small uav
    have a read and see what you can fund

    now about the thales and mbda joint AC venture which is the base of this claim
    again i can find nothing to indicate this, do you have a confirming source
    or do we need to contact thales and mbda to confirm this
    after all BAE, EADS and Finmeccanica would of had to agree to it, IP is closely monitored

    For Jackjack :

    i wondered why you didnt put a link, so i googled and found the answer
    http://www.fighter-planes.com/info/rafale.htm
    by bill sweetman
    surprise, so sweetman claims he is right and rafale has AC

    it shouldnt be too hard to find the MOU for joint research into AC between thales and mbda
    do you have a link to the MOU or will i email thales and ask for it or should i ask mbda ?

    as well as the many mistakes in the article that we can list, you also left out this part

    Dassault, Thales, and Snecma have no doubts that the Rafale embodies world-class technology, and its failure to secure export orders is clearly a source of frustration, as evidenced by Dassault’s attempt to file a lawsuit against the Korean government following Korea’s choice of the F-15. There are, however, a number of factors that have held the Rafale back. Along with the Typhoon, which has won a single contest in Austria, it is one of the more capable and expensive aircraft on the market. The Rafale team argues persuasively that its unique features work and address operational needs, but some customers may prefer the tried US-type approach to missile armament or cockpit ergonomics. Above all, the French government’s drip-feed of funds into the program does not engender confidence that the necessary upgrades will be carried out – even though the program is, in reality, as secure as any. Singapore will indeed be an important test for the aircraft

    hasnt the list of nations that have declined grown since then
    as for ‘AC’ spectra, even UAE want the spectra system brought up to date before they buy rafale
