    Nicolas , you completely misunderstood what I said .
    Let ‘s try again together , shall we ? ๐Ÿ™‚ Good .

    I said :

    AFAIK , the M2000-5 ‘s autopilot does it too and since , well …
    What I am talking about is not setting up a “safe” interception route but setting up an evading course at the edge of the enemy detection range , which is vastly more difficult .

    You responded by :

    What he was describing was just that

    when HE said :

    The autopilot of the Typhoon can automatically fly attack profiles and interception manoeuvres

    I am sorry Nic , but Scorpion NEVER talked about evading one or many threats .
    He talked about , I quote AGAIN :

    automatically fly attack profiles and interception manoeuvres

    Do you get it ou je te fais un dessin ? Bordel , c ‘est pourtant pas compliquรฉ ! ๐Ÿ˜Ž

    Scorpion :

    Really? You just recently stated the Typhoon isn’t what it should have been a “silent” interceptor and repeatedly came up with Rafale’s passive targeting capabilities insisting that the Typhoon can’t…

    I have never said that the Typhoon can ‘t do silent interception . What I said is that the Rafale is better at it and that ‘s a fact . Silent interception with SPECTRA , OSF and IR Mica (that you don ‘t have) has been one Rafale ‘s wanted capability from day one . Check the first FoxThree publications , you ‘ll see .
    Now , you keep thinking that DASS can do SPECTRA ‘s job which is far from the truth . But hey , it ‘s your opinion as we like to say .
    I already posted more stuff than I should regarding SPECTRA ins and outs , including some technical papers on Superheterodynes , Bragg cells , GaAs MMICs (here DASS is “folding”) and subtilities behind and within the software running the show .
    Have we ever heard of a possible “Active Cancellation” capability for the Typhoon ? Ever ?
    As we say in France , there is no smoke without a fire .

    ATR? Source please!

    Do you mean “Automatic Target Recognition” ? If so , what with ? The RBE2 or the OSF ? Because the RBE2 will make the difference in between a F-15 , a F-16 or a Fulcrum (example) by counting the engine blades and the RBE2-AA will prvide iSAR . The OSF provides a video of the aircraft so …

    NCTR is just yet introduced with the RBE2AA whereas Captor offers that capability since years!

    Correct and I respect this capability .

    if the resolution isn’t good enough you might not be able to match the returns adequately against your db.

    Correct again and clever thinking . Do I really have to say that I trust Thalรจs ๐Ÿ˜€

    Fine that your AESA scans faster (albeit 200000 times? Source please for the scanning speed thanks!)

    A mechanical radar like the Captor needs around 2 whole seconds to go from 9 O ‘clock to 3 O ‘clock , then the scan rate during the plate rotation is way slower than a simple Pesa radar since the beam is not electronically steered . I am not even talking about the time needed to scan the vertical plane as the radar is rotating , but I should ๐Ÿ˜‰

    As an example , the fixed RBE2-AA scans the entire field of view in about 100 nanoseconds . You can multiply this by 50 for the Pesa RBE2 (one beam) . Now , do the math ๐Ÿ˜‰

    Yes it’s mine opinion and that you don’t share it isn’t surprising as everything which states Rafale not superior is out of consideration for you!

    Talk to me about the F-22 , the SU-27/35 , the F-35 and you ‘ll see that I consider the superiority in some capabilities . But here , we ‘re talking about the Typhoon . ๐Ÿ˜ฎ
    Really , if Dassault wanted to make a souped-up M2000 , they would have built the Typhoon , but better :diablo:
    Sooner rather than later (when the AtoG weapon integration will be completed) , the Typhoon users will learn the hard way when they ‘ll fly at 450Knt @100ft with a full load in terrain following mode . Ouch ! ๐Ÿ˜ฎ
    Ouch for the range , ouch for the hard ride . Not even talking about DASS here ๐Ÿ˜€

    Yes we can discuss the Typhoon as it is a fighter who shouldn ‘t be underestimated but don ‘t compare it too much with the Rafale .

    Cheers .

    redreidy :

    Bluewings i have a mission for u that the typhoon is better.
    Time critical interception of a high alt bombing force… rafales slower, shorter range missiles and radar.

    Aaah … Yes , you ‘re correct . Nice catch ๐Ÿ™‚

    Scorpion :

    In contrast to what you believe/claim the Typhoon is perfectly capable of conducting silent interceptions using DASS, PIRATE and MIDS, not unlike Rafale with SPECTRA, OSF and MIDS.

    I never said otherwise , I perfectly know that the Typhoon can do passive shooting , thank you .

    PIRATE alone can actually gather a lot of information including angular position, range, speed, acceleration rates and whether a target is approaching or receding. It generates target images for visual ID on selected threats and work goes on to include a multitargeting mode with imaging capability and EADS works on an automatic target recognition software since years which is used to identify targets on base of the signature with PIRATE and Captor.

    Yes , similar than OSF and RBE2 .

    Captor is right now capable to ID AA-targets using the non-cooperative identification feature, something the RBE2 will just introduce with its AESA antenna

    This is software related and has nothing to do with radar performance .

    even with the AESA antenna RBE2 won’t exceed the resolution of the current Captor-D !

    You know what Scorpion , you don ‘t know what you ‘re talking about and furthermore , you forgot to say that while the Captor-D is doing SAR , it can ‘t do anything else meaningfull . :diablo: It is mechanical !
    RBE2 is scanning the entire field of view 200.000 times faster than the Captor-D , my friend .

    Wrt resolution :

    http://i52.tinypic.com/t6yvx0.jpg

    It ‘s rather good .

    DASS provides very similar passive detection capabilities to Spectra.

    This is your opinion and I don ‘t share it .

    The autopilot of the Typhoon can automatically fly attack profiles and interception manoeuvres

    AFAIK , the M2000-5 ‘s autopilot does it too and since , well …
    What I am talking about is not setting up a “safe” interception route but setting up an evading course at the edge of the enemy detection range , which is vastly more difficult .

    Scorpion :

    That’s actually interesting as you believed that such a range performance (250km+) would be unrealistic for the Captor-E

    Both Typhoon and Rafale don ‘t have the output power to reach such performance , as I said multiple times .

    Given the size of the AN/APG-77 antenna it’s not non-feasible that it features 1500 TRMs.

    Some sites even say that it features 2000 TRMs rated at 4w each (8kW total output power which is inferior to the actual Rafale ‘s 9.6kW)

    And don’t forget about the fact that the latest variant is the AN/APG-77(V1) with latest TRM technology !

    Who says so ? I have been unable to find anything on this matter and I still don ‘t lnow what kind of TRMs/MMICs the (v1) is using . Do you ?
    To be perfectly honest , I am indeed aware of rumors saying that the (v1) is using GaN MMICs with TRM rated at 20w each .
    We also know that Raytheon ‘s first try with GaN was a failure : the APG-77 reached its max temp in normal search mode and part of the plate was dammaged in one second when they tried jamming mode .

    PPP :

    F35 and F22 all have canted arrays presumably to reduce the frontal radar cross section, and so a canted array would be indicative of an attempt by Dassault to reduce the Rafale’s frontal radar cross section.

    Canted arrays don ‘t reduce much the array RCS :
    RCS of an Antenna
    For the case of an antenna the total RCS can be divided into two separate components as Structural Mode RCS and Antenna Mode RCS. The two components of the RCS relates to the two scattering phenomena that takes place at the antenna. When an electromagnetic signal falls on an antenna surface, some part of the electromagnetic energy is scattered back to the space. This is called structural mode scattering. The remaining part of the energy is absorbed due to the antenna effect. Some part of the absorbed energy is again scattered back into the space due to the impedance mismatches, called antenna mode scattering.

    Then , wrt Typhoon ‘s RCS , the fighter has the disadvantage to use a mechanical steered array which means that the plate is always moving (whatever the fighter is doing) and is reflecting the incoming electromagnetic signals all over the place .
    The SU-35 has the same problem (video) :
    http://www.youtube.com/watch?v=yELuKJFDM80&feature=player_embedded

    TooCool resumed it very clearly with his example :

    put a small mirror on the wall, perfectly vertical, and try to see yourself in it… you’ll notice that, unless you are straight in front of it, you can’t
    canting antennae, gives you one positive thing: a bigger array for a given nose diameter, allowing for more modules, or more space between them (better for cooling)

    @Kirtap : +1 ๐Ÿ˜‰

    PPP :

    Bluewings justified the T/R modules claim previously on the assumption that French engineers are better than British engineers

    In some (many I should say) important fields , yes they are , in others not .
    Also , since the French MMICs (GaAs and GaN) are made in France by UMS S.A.S France (Orsay plant) under Thalรจs survey , the British (and others like Selex) have very little idea of what the RBE2-AA is made of .
    What UMS Germany is doing for the Captor-E is a different matter .

    I believe there is a joint run T/R module plant between Germany and France too, so it would be interesting to see how the French twist that one

    We do it by ouselves in our factories , as usual . Now , you know . :diablo:

    Now , wrt this :

    Thales is โ€œfive years ahead of anybody in Europe or the U.S.โ€ in active arrays for airborne radars, according to Jean-Nรถel Stock, Thales vice-president UAVs and intelligence, and a former program director for Dassault Rafale airborne systems.

    I am skeptical .:confused: Maybe they found something new , a breakthrough of some sort … it wouldn ‘t be the first time ๐Ÿ™‚

    Scorpion (on a different thread) :

    Btw why don’t you come up with graphics which demonstrate your claims for the Rafale, preferably in the Rafale thread.

    Ok :
    http://i52.tinypic.com/xn5dw3.jpg

    Look at it carefully and if you don ‘t understand something , ask me .
    But you can notice the work done by the EMTI , the SPECTRA display and also the main tactical display showing the overall picture , the video (or iSAR picture) showing the target and a vertical cut of the situation at hand giving a clear clue of altitude differences . Very usefull feature in BVR ๐Ÿ˜‰
    Typhoon ‘s displays and sensor fusion is half a league behind .

    Scorpion , could you give again the link to the DASS pdf , thank you .

    I quote :

    “The DASS also has full control of the RF transmitters and receivers allowing optimisation of emission control and crossaircraft sensor management, including a stealth mode for controlling RF transmitters in covert operations.”

    I wasn ‘t aware of this , so I stand corrected . Thanks .
    Anyway , we all know that emission control with a mechanical radar is rather basic since we can ‘t ask the radar to perform selective output power in sector “X” while scanning with a different output power in sector “Y” and/or “Z” and certainly not simultaneously . Then , ask the Captor to modify (adjust) by itself its output power in real time to “just” light-up the target with the minimal power needed to do so as the target is closing in . Then , you can ‘t ask the Captor to “beam” its radar cone in just a very small portion of the sky (like a laser pen vs a light-torch) .

    As I said , the EMCON concept is not possible with a mechanical array . It is just not flexible enough .
    I only hope that DASS has been built with the Captor-E in mind .

    Now , regarding the sensor fusion , we should understand the difference in between getting and gathering the infos and managing them .
    While the Typhoon is perfectly capable to detect possible threats in a 360deg bubble and display them in one of the side display , it can ‘t provide possible courses of actions to the pilot , like the possibility to ask the autopilot to set-up a new flight plan from the RF findings (and avoiding them) because there is no AI running the show in the background .
    DASS (and the Logic behind Praetorian) is not made and tailored to run the entire weapon system ~the aircraft .
    It is why I said that Rafale without SPECTRA is not even thinkable .

    Scorpion , just look at the “sensor fusion” graph you ‘ve posted .
    It shows that track No1 (top) is followed by radar and MIDS , track No2 is followed by radar , MIDS , FLIR and ESM . Track No3 is followed by etc …
    Ok , fine , the Typhoon can track with multiple sensors .
    But , look at the picture you posted showing the supposed “God eye view” (DASS) , what are doing the targets ? Are they tracking me ? What with ? and which one ? Are they all tracking me ??? :confused:
    I don ‘t know ! ๐Ÿ˜ฎ

    SPECTRA will tell the pilot the answer to most of these questions and even propose a possible course of action .
    In this scenario (5 different targets) , it is already difficult to engage an active jamming if the targets are the same aircraft (ie: 5 F-16s = same radars to jam) but if they are different aircraft with different radars , the only thing DASS can do is to try to blanket the most obvious frequencies with noise (not very efficient) , hope for the best and use the towed decoys as last defenses .
    OTOH , SPECTRA can “blanket” but also can try to take each adverse radar separately ~thanks to its AESA antennas and beam forming capability~ and find a tailored jamming for each of them .
    (we had a confirmation by Eagle1) :

    the best case is to have performed ELINT to allow tailor-made jamming mode against a given asset. He said SPECTRA was very good at spying the transmission and comes up with adapted jamming modes in a short time.

    I am not sure that it would work that good versus 5 adverse radars but it would surely work better than DASS anyway .
    As I said many times , the Typhoon hasn ‘t been designed as a “discrete” fighter capable to make its way unarmed (or unnoticed) to Moscow .
    The Typhoon ~as an interceptor~ is a souped-up M2000 and will also end up as a good bomber but it is certainly not a benchmark in any of the actual or planned missions .
    It is an excellent aircraft , better than any F-teens in AtoA , maybe on the par with a SU-35 in combat but inferior to the Rafale in every missions you can think of . Sorry to say (again) .

    Cheers .

    By the way , I said :

    If the RBE2-AA is indeed equipped with some of these modules , a total output power of around 20kW is theoretically possible .

    Just to put things in perspective , the F-22 ‘s AN/APG-77 is quoted to have around 1500 GaAs MMICs with a total output power of around 12kW (less than the RBE2 with a new cooling pump) . Each module is at least capable of emiting 13,33w (lesser than the proven capabilities of Rafale ‘s UMS MMICs) .

    But , on the F-22 site , we find even worse (!) :
    http://www.f22fighter.com/radar.htm

    It is said that the radar only has 1,000 modules , each capable of emiting 4w (:D) . Total output power : 4kW . Is this real ? :diablo:

    Just to say … ๐Ÿ˜Ž
    Then , the good old USA are trying to make us believe than the APG-77 has a 220km+ detection range versus a fighter size target . Is the target a 15sm F-15 barndoor ?
    If it ‘s the case , the F-22 would detect a AtoA loaded Rafale at around 70-80km , in range for an immediate response like a volley of MICAs provided by SPECTRA and OSF/Damoclรจs .
    Funny , isn ‘t it ? Maybe it ‘s the reason why the USA refused BVR combats with the Rafale … :diablo:

    Cheers .

    To be honest , I don ‘t think we ‘ll know the exact TRMs counts on the RBE2-AA until its real deployment .

    I am sure that the RBE2-AA prototype had ~at one moment in time~ 1,001 modules . It might not be the case anymore , mind .
    Since , Thalรจs and UMS could have updated the plate with newer TRMs providing more output power per Watt/consumption . In this case , reducing the total amount of TRMs would help the cooling while gaining in range , as well as keeping the power consumption acceptable .

    Anyway , we already have some clues and if we add one to two , we might get some more clues ๐Ÿ™‚
    We know that the actual RBE2-AA has an output power of 9.6 kW . If it has 840 TRMs , we know that each module is at least capable of emiting 11,42w . Then , Thalรจs and Dassault just said that by fitting a new cooling pump , the total output power reach 14kW which means than the same modules are capable of emiting 16,66w .

    When one do a quick research at UMS , one learn that their best MMICs can reach somewhere around 24w .
    http://www.ums-gaas.com/telechargement.php?id_page=0-42-19&file=24_26GHz_UMS_MMIC_solutions_for_Industrial_Radar_Sensors_2.pdf
    http://www.admiral-microwaves.co.uk/pdf/ums/UMS-news-letter.pdf
    If the RBE2-AA is indeed equipped with some of these modules , a total output power of around 20kW is theoretically possible .
    So , as Scorpion rightly said :

    Is the available power output the limiting factor?

    Indeed it is . I said so for a very long time ! ๐Ÿ˜Ž
    What I really would like to know is the total output power needed by SPECTRA when in full use , including during active jamming with its GaAs AESA antennas .

    Anyway , the numbers provided by Dassault , Thalรจs and UMS wrt the RBE2-AA are an “eye-opener” . I mean , if Dassault was to find a way to boost Rafale ‘s electrical system , the Radar could have a 250km range (!) vs a F-16 size target . This is better than the SH ‘s AN/APG-79 .

    I don ‘t expect this kind of performance anytime soon but since Dassault talked not long ago to do a full review of Rafale ‘s electrical system , I find it relevant to look into a possible futur .
    Then , knowing than GaNs MMICs are planned (SPECTRA then RBE2) , such very high performances could be archived with a total output power of only 18kW , which is perfectly feasible and with a … small nose :D.

    Cheers .

    Stryker73 :

    You’re kind of forgetting 1990 is the end of the cold war and 4.5% defence spending. Peace dividend etc. You will find most countries armed forces nowhere near what they were in terms of numbers.

    Very true , one has to look at the shape of the Russian Forces . No-one in Europe needs anymore a 4%+ defense spending .
    Russia is actually buying 2 Mistral Class Ship from France and is going to build 2 more at home with the ToT . That would have been impossible during the cold war , things change .
    Mistral :
    http://www.naval-technology.com/projects/mistral/

    I am following this thread with a great interest because we also have the same problem in France . Here , things are a bit better than in the UK mostly for one reason : the French industry ~in general~ is in better shape than the UK ‘s . Think steel , composites , cars industry , trains , civilian and military aviation , etc …
    In this regard , the UK lost years ago the capability to mass produce what she needs . Germany , on the other way , is the European Leader in manufacturing “things” and by a good margin .
    By stopping making stuff , you not only have to rely on others but you also loose the “know-how” and you don ‘t anymore pour money into R&D .

    Since the UK is obviously France ‘s main Partner in Europe ‘s foreign military affairs , we don ‘t really like what is happenng in the UK wrt defense spending and MOST IMPORTANTLY wrt to the RN , which is (was in fact) the corner stone of the UK .
    I am a nostalgic of the Great and powerful RN ๐Ÿ™‚

    Personaly , if we all think about a European Army , the fact that the UK has a lot of Chally is almost irrelevant since you ‘re living on an island .
    French Leclercs , Germans , Spanish , Swedes , Danish Leos , Italian Arietes , etc , can defend Europe on the ground .
    What we need from the UK is a powerful RN , a powerful RAF and the usual Commandos and SpecOps . We also need the full cooperation with the various Intellingence Services (which is already excellent but we could do better) and we need the UK to decide to put down the US Echelon spying system once for all . ๐Ÿ˜ก
    This is VERY important for the European Industry .

    Just my one Euro …

    Scorpion :

    If the 50% more range with an AESA turns out to be true you will look at 3-4 times the figure you stated.

    Are you saying that the Captor-E will detect a 5sqm target at 250km ?
    Well , it seems a bit exagerated and I can’t see how that would be possible with the output power at hand . If it is indeed possible , that would mean that many people including myself (modestly) were wrong .
    AFAIK , we don ‘t know the output power of the Captor-M , we don’ t know the output power of the actual AESA Captor prototype and we don ‘t know the output power of the futur Captor-E .
    I know that some papers are quoting the Captor-M to have one of the best radar range there is for a radar of its kind and I believe them .
    But it would be very hard for us to rate the futur Captor-E without pulling rabbits out of a hat .
    AESA modules count and dish size are 2 very important things , I admit , but it doesn ‘t tell the whole story .
    Personaly , I think that Thalรจs has a good 3 years lead wrt integration , back-end and software compare to the Captor-E . Then , the technology at hand might not be the same . GaAs modules MAY be the same but the way to use them could be different . Bets are on … ๐Ÿ˜Ž

    You have no clue about the Typhoon that’s your problem, add your utter bias towards the Rafale and it becomes clear that there is not the slightest interest in figuring out the truth about the Typhoon’s capabilities.

    I have been following the Eurofighter 2000 since , well … from the begining .
    I am truely disapointed to find out that you discard my posting so easily , Scorpion .
    I understand , saying that the Typhoon is a “souped-up” M2000 is not easy to swallow but there is not much difference in between the two . The Typhoon is a Sprinter , better acceleration at all regimes than the M2000 but same max speed , same altitude ceiling but with a bigger radar and a wonderfull IRST . The ECMs are probably on the par with the ICMS MkIII (M2000-9) .
    As a dogfighter , I would say that a Typhoon ‘s driver put up against a M2000 driver is going to sweat a lot .
    When I think that more than 15 years after the blueprint , they discovered that Apexs were usefull , I have a sarcastic smile on my face . Don ‘t ask me why ๐Ÿ˜‰ They made the Typhoon with a 30 years old Dassault technology (80s) .

    The F-22 uses three different sensor formats on separate screens as well.

    You forgot that the F-22 ‘s mains screen (and the Rafale ‘s) is a fusion is between all the available sensors with an EMCON concept , as well as showing a God eye view , which is not the case with the Typhoon .

    the DASS format provides a clear picture of threat environment if required

    This is exactly what I ‘m saying to you , IF REQUIRED . Yes the DASS has its own display (if the pilot ask for it , left side display) but it can ‘t be fusionned (if I may say) in the main display and with all the filtering needed to only show what what the pilot should take care of , while the rest is managed and recorded for immediat or futur use , as I said earlier on . Here Scorpion , I ‘m not talking aboput MMI but about sensor fusion . MMI will come later :diablo:

    while the PA format provides the overall picture with AA, AG targets, navigation information etc. All onboard and offboard sensor data are fed into the AIS which fuses these data, correlating sensor information, assigning joint tracks and priorities.

    Rgr that loud and clear but it is what every 4th gen aircraft do , more or less . Some do better than others …

    Nonsense! DASS requires not any input at all if not required, the IRST-attack format is only of relevance if the radar is on standby or off

    Really , are you sure !? ๐Ÿ˜ฎ
    First : “DASS requires not any input at all if not required” is a nonsense . Read again what you said , english language is cristal clear but you ‘re not . Then , if PIRATE is only used when the radar is off or on stand-by , you know jack about the Typhoon .

    it doesn’t need the DASS display format unless you want to get a clearer and more detailed picture of the threat situation beyond the standard indications.

    Unless I want ??? ๐Ÿ˜ฎ I want EVERYTHING and NOW !
    If I have to go through buttons and switches ~if the system is capable of doing so~ to understand what is tracking me , where , how far , I prefer to eject right away , come back to base and ask to fly a Rafale for my next mission ! ๐Ÿ˜ก

    DASS actually manages the active emissions of the aircraft

    Wrong . Sources , please . :diablo:
    Then , to perform such tasks , DASS would need to be in charge of the Captor to manage a true EMCON concept , which is not the case and a mechanical radar is not the best to manage multitasking (ie : SAM tracking at 11km , adverse fighter tracking at 85km , terrain following) which suppose excellent output power flexibility and fast beam stearing .
    In fact , the EMCON concept with a mechanical radar is of little use .
    In this regard , the Rafale is well ahead and the RBE2-AA will benefit for free of what is already implemented .

    Some should ask themselves why Dassault decided to use a PESA radar from the begining instead of a more powerfull mechanical radar , like a RDY-MKII .

    Dassault folllowed a different route and it shows . Wrt sensor fusion and pilot ‘s ease (is that making sense ?) , the Rafale is probably superior to the F-22 while being inferior in BVR due to RCS .

    Twinblade :

    and the odds on your beloved fighter ?

    Versus a SU-35 , Rafale is on 50/50 . Maybe 65/35 for Rafale if SPECTRA can hold the Flanker until 60km to target .

    Cheers .

    Toan , this is important :

    GaN will be chosen more for high-power and higher frequency applications where its attributes overwhelm those of GaAs. This will increasingly occur in defense systems

    I give you an example , if the actual RBE2-AA was using GaN we would not need a better cooling pump when we push @14.000+ Watts . Then , we would also get a better range .

    AESA radars will be one of the first application to use GaN instead of GaAs . My guess is that the Captor-E will run 3 to 5 years with GaAs and then will be upgraded with GaN (maybe around 2020).
    Personally , I think that the Captor-E will have a better range than the RBE2-AA (maybe a 20-35km advantage) .

    Also , since GaN is using less power than GaAs for the same task(s) , the software running the whole thing should be able to do more at the same time (like SAR + TF + AA search) more discretly .
    What needs to be done on the Typhoon is to implement the EMCON concept . This way , the top of the line Radar , IRST , RWRs , Link16 , etc , will work together and the defense system (software hard work) will be able to manage the different emissions to get the best out of very little in a discrete manner .
    The F-22 and the Rafale are very good at it ๐Ÿ˜Ž
    The F-35 also look very promissing .
    We often talk about “sensor fusion” and some think that displaying 3 different sensors on 3 different screens is “sensor fusion” (Eurofighter) , no it is not .
    The Typhoon ‘s driver has to check the various screens , understand the situation at hand and think about a possible solution . If he needs or ask the Typhoon ‘s sytems to rely primarely on one sensor or two (radar , IRST , Praetorian) because the situation needs it , he has some work to do in the pit by using button push and switches .

    With the Rafale , the defense system is running the show . It presents on the main screen all the findings RELEVANT to the situation at hand , recording and filtering out the rest for immediat or futur use . The mission AND the pilot decide the EMCON level (same with the F-22) . To make it short , when the Rafale detects something , everything is done to track the target with the most discret sensor at hand and use the other sensors only to fullproof the tracking if it is needed .
    This is NOT done by the pilot but by the aircraft itself .

    There is no other reasons behind the Rafale ‘s edge on the Typhoon wrt BVR fighting . The French said so and so many times than some should understand the concept at hand .
    It is mainly the reason why I say that the Typhoon is nothing but a souped-up M2000 . The fighter is somehow lacking in what should be its main task : to kill silently without betraying its presence .
    I imagine a surprising fight in between a Typhoon and a SU-35 and I know who I put my money on . If I was a UK bookmaker (they are the best) , I would give the Sukhoi a 4-1 odd and a 10-1 for the Typhoon .
    I bet 50 quid on it ๐Ÿ˜‰ Any taker ?

    Cheers .

    What an ugly bird … ๐Ÿ˜ฎ
    Then without its big engine , it is a brick .

    Luckily , it has some top of the line avionics .

    Cheers .

    Some good posts here .

    I don ‘t know who you are Mr PhilipG but I can only agree with you . In fact , you nailed it in 7 lines with style and common sense .

    Scorpion :

    it’s naive to believe that the aircraft will become much more expensive now where it is in production, it’s in fact much more likely that the aircraft will become cheaper As it matures and full rate production is ramping up.

    Fine but we still don ‘t know how much it ‘s gonna cost to start with !
    Then , maintenance , maintenance …

    redreidy :

    i was under the impression that the F-35 was designed to from the start to have pretty low maintenance cost, with the 3 types of aircraft sharing 80% of components

    That ‘s true (and still is AFAIK) but there are so many problems , foreseen and unforseen (yes) that no-one knows for sure WHAT will be the end product .
    Some people on the Net should wake up a lil ‘ bit and ask themselves why after building a gem like the B2 and a pearl like the F-22 , the USA have so much difficulties with the F-35 . Think about it

    Please , don ‘t give me the “they can ‘t make a F-35 priced at half a billion $” because it is irrelevant . The most important factor is why the USA are having such a hard time with the F-35 ?

    I tell you why in my humble opinion : from the very first blueprint to this day , the project has been missjudged , taken lightly (no real importance) , badly ran and badly overlooked .
    It is not unusual to see US aircraft being late and more expensive than planned but the F-35 is going to brake all the previous records .
    You bet ? :D;)

    i wouldn’t be surprised if we get a limited number of F-35C for now and at a later date there was a purchase of the A or B model.

    The “C” version is the only one you can still bet on . The “A” has no futur (if it ever has any) and the “B” will never work .

    Cheers .

    Scorpion , I only responded to your questions . ๐Ÿ˜‰

    Anyway further discussions wrt the Rafale and its equipment should be allocated where it belongs to (the Rafale thread)

    I agree .

    Cheers .

    Scorpion , I understand what you say and I tend to agree with you , at the condition that the F-35 will work .

    If you read me carefully , you know that I am not underestimating the F-35 .
    If it works as intended , for a decent price and if possible (God please) with not too much maintenance .

    To me and this is my opinion , the F-35 will end-up as a financial black hole not worth the money with huge maintenance cost and various other problems .
    In fact , the USA shoot themselves in the foot . As a “trap” to kill the European industry , it does marvels and still do :diablo: but the USA have to buy it too . Bless them :o:D

    My “little finger” is telling me that the F-35 will be a dog to run , and my little finger is rarely wrong …

    Cheers .

    Scorpion :

    Really “all kind of modes”? So what about GMTI/T, EA, interleaving of GMTI/T & SAR, simultaneous tracking of AA, AG and naval targets etc.? Sure “all modes”.

    Why do you ask ? You know the answer as well as I do .
    GMTI/T is currently implemented on the actual RBE2 , simultaneous tracking of AA , AG and Naval targets are already implemented , since the standard F3 .
    Interleaving GMTI/T & SAR is also a feature of the RBE2-AA , obviously .
    AFAIK , the RBE2-AA is about at the same stage than the actual PESA RBE2 wrt modes .

    Cheers .
