    The s-300/patriot shield would be the last defence against this threat, what about a pre-emptive attack against bombers? why not?

    The Backfire was considered for this mission?

    The s-300 would be a bad cost effectiveness solution, when you compare it with a very long range interceptor

    I would love to see the US ideas for a long range interceptor on the 80’s, sure there must be some out there

    Would love to see this;

    The number one rule of ALCMs is don’t shoot them at anyone who can shoot their own ALCMs back at you.

    I dont know what to say dj,…but that doesnt solve the engineering problem..

    An medium size bomber that can actually do the long range interceptor role could do the job, something like the su-34, for example, would like to know if that was considered, maybe using the su-34 with r-33’s, seriously the ALCM issue, is far more important than the stealthy fashion.

    Wonder if the USAF have been considered that problem, especially in the 80’s something like a modern tu-28 was badly needed, IMHO

    Not big surprises, really

    1-the missile load is not enough for such big aircraft like the 22
    2-Heavy ECM enviorement leads to close combat
    3-There are not “magic” pk 0.99 Amraams, or R-77’s, most of them will fail and badly.. the “close combat is dead since the 80’s” was brought by western trolls, please check why the USAF did not chose the “stealthier” plane in the ATF contest..

    About the 22’s turn rate at which speed is done?..at lower speeds with lower aerodynamic g’s you can actually turn better than at the max g corner speed, with TVC that would not be a surprise

    Still is funny how you guys defend your f-22/su-27/f-15 toys ..

    ohh yeah and the typical “you are a fanboy” bash, and the “you are an -hated member by western cheerleaders- clone”…come one, grow up..

    One last thing, God guys, pilots are not the kind of guys you are thinking, the guy in the briefing is a pilot, not an engineer

    Im sure the su-35/rafale/f-22/typhoon EW suit , is in concept, and aplication almost the same, unless they are using a revolutionary technology.

    Between all the teams the only one that is investing and researching on “revolutionary” techs are the russians with their plasma stuff, seems these were old news, but i was surprised by their IRBIS antenna plasma screen (the plasma actually can increase the sensitivity of the passive receptors)

    I dont think that neither the americans, french and brits are researching something similar, neither on the superconductors field, all are refined old techs.

    Spectra is a conventional EW system with a lot of marketing and nice myths (active cancelation of EM waves…good luck with that)

    You guys are getting overoptimists about EW in the rafale, is hard to tell how good is

    Is very funny how some terms are being coined so easely to promote some planes, since the 90’s the marketing campaigns are getting really annoying, with these dumb phrases like “unfair advantage”, and ppl just repeat the same stuff without any objetive argument

    I still have my suspects that the Rafale was/is a “teenized” concept of the traditional french fighter..with their weak points

    In fact what I understood was that it was better investing money on an EW suite rather than going in an endless competition of bigger weapons, bigger radars

    If you are investing on EW, you are going on the defensive side, and you depend on the accions of your foes for your tactics, losing initiative.

    The lightning was too heavy for such task, you are comparing for the same role planes with 5-6 tons with a 12 tons one …

    The lightning was overcomplicated and in general a failure as design, a 12 tons monster with such small radar room and fuel/range problems with a limited task

    The performance of the US and SU aircraft was rising too quickly from the 50’s, the UK industry just wanted to match that performance, leading to overcomplicated designs which were not effective, meanwhile the french industry went to more practical ones, which at least could fit partialy their needs.

    The UK industry lost it north, and went “desperated” with their “requirements” for medium sized airframes, so they were looking for help to germany and other countries, always trying their idea, they went to the Tornado, an outdated design based in old concepts…meanwhile dassault was just designing something based on the Mirage III with FBW and unstable concepts.

    Perhaps the decisive nail that sealed the UK industry coffin was the RAF’s adquisition of the F-4, but that was more like an effect of the stubborn of their designers, or maybe the RAF requirements…or “requirements”

    Funny is that the Gripen looks more french than the Rafale, and i think is for that, the gripen is a success in the market ,either way i think at the end the decition from dassault to quit the EF project was the best for dassault.

    the only purpose of saw tooth is stealth. I had the confirmation from two rafale pilots three weeks ago in paris. The rafale B301 was displayed at “place de la concorde” for the celebration of one century of french aeronautics as well as many other aircrafts. I posted a personal picture of this event on this thread.

    Is ok, but seriously, i would not ask these questions to pilots, they fly the thing..they did not design it..

    Still have my doubts about that stealthy feature..but is not a great issue or polemic

    I just cant see any significant LO feature on that plane, being worried of the leading edge RCS when you have such rounded airframe….is just not logical, neither the placement of it, if you can see in the ventral rear fuselage there is also these weir sawtooths..why always are placed on the rear side of the thing? , but is ok, i wont open a debate about that

    You should think again, the leading egde from wing and canard are highly sweeped!

    The f-4 wing also is “highly sweeped”….are you kidding right?

    The sawtooth pattern on the Rafale is patchwork for fix the reflex problem on straight gaps (90° )and near straight trailing egde.
    Without this sawtooth the traveling waves bounced back direct in direction to the enemy Radar.

    Su-47 and Stealth is a bad joke.
    The forward sweeped wing and the LERX set up a 90° corner reflector (reflector stud)!

    These “sawtooth” have a heigth, wich is not oriented to the trailing edges, i bet is some kind of special (low drag) aerodynamic device rather than a stealthy feature

    Go ask the F-117/F-22/etc designers…:D

    😉

    I doubt these have something to do with any kind of RCS reduction…since the f-117 was unveiled some guys are willing to see things that do not exist…same goes with the EF

    The AESA news are a surprise, good for the Rafale team…lets see how it does in the Indian contest

    I dont know if the russians are willing to show the engine itself on that video…still i find a bit surprising how narrowed is the heated (on blue, btw) gas stream, if you compare with the exhaust size, eve at mid power is interesting…..the video does not show a “stealthy” nozzle (which i doubt the russians are willing to show, anyway)….but it perhaps shows something far more important.

    Either way…the video is posted by one of these russians angry fans….oh well..

    Besides all that , this just could be another “pakfa” video…showing mig-29’s, su-27’s and everything but a single pakfa screw…

    Star, seriously that whole semicondutors, economics, industry , X vs Y, and “if they would get more money” debate has nothing to do with the thread, go to the general discussion for that….

    Now, can someone tell me what is the real size of the PAKFA?, will be heavier than the 22? or will have the “20 tons normal take off weight”?

    I never would have expected that the trolling and bashing would have plaged this thread…well anyway it was funny…

    About the topic, how is the performance of the Rafale compared with the M2000?, not always “new” means better in all aspects, the Rafale is using very advanced aerodynamics (perhaps the most advanced topology design), based mainly on the lift side, while the M2000 is based on the low drag side, any good diagram to compare the performance of both planes?

    I dont understand…which is the real weight of the pakfa? heavier than the f-22 (as some rumors claimed) or lighter than the su-27 (as claimed by the chief design)?

    Most ppl claim that the huge quantity of money spent on R&D is a sign of the F-22’s superiority….but that is realy a sign of how bad was managed the program, how bad was rushed the design, how the things were changed in the last moment, etc…goin from 14 tons to almost 20 tons of weight, decreasing the % of comositive components, finding problems on subsonic regime (changing the wing design), seriously they did restarted all over again..just compare it with the f-15/16 program…, of course for the public everything is shown as “the 8th wonder on the world has it cost”…

    If the russians would have chose, and began the PAKFA airframe in the 2002-2004, is probable they would had the same “R&D superiority”…..with the consequent programs end

    Here’s an example of how Russian air space isn’t inpenetrable

    http://englishrussia.com/images/rust.jpg

    Please explain why the PAK FA features stealth, if it’s of no utility. You can’t have it both ways. Either it’s a good thing, or it’s useless, and I believe the former to be true.

    Man, that plane was followed by su-27’s and Mi-8’s..that was never told, or made public on the west, of course for delight of the western trolls..

    My point is that you are -as almost every stealth cheerleader- confusing the reasons of the poor quantity of “stealthy” planes with the end of the cold war and a suppossely extremely complicated alien tech of the f-22/35…
