    Shadowpuppet :

    This is a rude awakening for every military program in the West, the delays, the corruption, the finger pointing towards one party or another, the political meandering to get X built in Y Country/State to satisfy voters in order that Z politician gets re-elected. In turn meaning the military goes without necessary equipment, costs skyrocket and when the damn thing is delivered, well, it’s been so delayed and forced so overbudget – it’s already outmoded and there’s no money left in the kitty to bring it up to date. So then mothball half the fleet and modernise the other half 20 years later.

    True and well said .

    I expect hundreds of stealth aircraft to be in the inventory of the Chinese Air Force by 2025. Minimum of fuss. It’ll just be done.

    We think alike . By 2025 , the few F-22s based at Guam will get sweaty at each take-off . πŸ˜€

    Cheers .

    Congratulations to China πŸ™‚

    This jet is “bizarre” , very strangely designed .
    It is clear that the Chinese have their way …:cool:

    Witnesses say that it is very stable in flight and the landing was very smooth .
    The fact that they used domestic engines for the first flight tells us about how much they trust their own stuff .
    They learn fast , real fast .
    I still find the overall design rather … strange . I would like to see its manoeuvrability in subsonic regimes and its ability at dogfighting … :rolleyes:

    This F-35 business, I just do not feel comfortable with it…IMO theres not much of a plus side. But lets see, eh.

    Right thinking and well said . πŸ™‚

    Wanshan :

    I asked if it would not actually be more correct to state that Tornado is a better bomber than 18E

    Yes it is correct about range , payload , speed and robustness .
    But it is incorrect regarding radar , avionics , etc …

    The Tornado has been and still is a hell of a fast mud mover , furthermore its crews always trusted it and praised it . What the Tornado did demonstrate the early days of GW1 is nothing short of outstanding .

    aurcov :

    I red somewhere that the fuel reserve for naval planes is considerably bigger than for land based planes.

    True . The Rafale M ‘s required reserve is 2 tons internal (for safety) while the Rafale Cs and Bs ‘s required reserve is around 1.2/1.5 ton internal (if I am correct) .

    Cheers .

    Mabie :

    In my mind, it helps explain the difficulty adversary aircraft have had in dealing with the F-22 it in both BVR and WVR regimes

    Your mind is wrong and some adversaries don ‘t have any problem to deal with the F-22 in WVR .
    The USAF refused the use of Sidewinder and IR Mica during the F-22/Rafale dogfights because it would have proved that LM and some various pilots blatantly lied .

    the famous quote by the Aussie F-15 pilot that he couldn’t lock onto the Raptor when it was clearly visible thru his canopy.

    The worse lie I ever heard :diablo:

    Spudman :

    Modern IIR seekers do not look for simply a heat source, but the entire field of view as an infrared image. Flares would just show up as hot dots falling away from the fighter. The image of the target fighter will not be blocked or obfuscated by the use of any flare.

    Very true .

    Cheers .

    Spudman :

    It would likely get a similar A2A tracking ability like that of the EODAS, but will still lack in range & resolution.

    Wrightwing :

    The system already provides this capability against missiles. The upgrade was to provide the capability against other fighters, etc… so that once the -9X was integrated, the F-22 would be able to take advantage of the HOBS/LOAL features.

    -1) F-35 ‘s EODAS and F-22 ‘s MLD are two very different systems in term of resolution and capabilities .
    EODAS beats the crap out of AN/AAR-56 . Sure , F-22 ‘s MLD could be upgraded but so far nothing has been done .
    EODAS can even track ballistic missiles at up to 800 miles (!) with a 10x magnification but it can ‘t be displayed on the current F-35 tactical display . Video :

    Quote :

    “DAS is an omni-directional infrared system that can simultaneously detect and track aircraft and missiles in every direction, with no practical limit on the number of targets it can track. DAS truly revolutionizes the way we think about situational awareness,” said Dave Bouchard, program director for F-35 sensors at Northrop Grumman’s Electronic Systems sector.

    -2) Such systems are not capable to provide any range , so using the systems to direct a AIM-9X in LOAL mode is only possible in WVR .
    Russians and French tried it with our respective IRSTs and it only works in WVR , as expected .
    When used for a BVR shot , even the IR Mica needs in-flight updates or the help of the LRF , which only works at up to 30km .

    Believe me , we all wish to fire passively an IR missile at over 50km but it is so far impossible unless to use data from an excellent RWR , or from an external source like AWAC or ground radar or another fighter illuminating the target .

    Wrightwing :

    I think that article you posted answered your question on the challenges an ECM system has vs an agile radar, and missile.

    Not really .
    Mr. Gambit was probably not aware of the progress made these recent years wrt ECMs . I admit that it is more difficult to jam an Aesa radar than a mono-static multipulse missile radar , the later not even being LPI .

    I found it ironic that you simulataneously praised it, and dismissed the issues it addressed.

    I praised Mr. Gambit ‘s ability to describe the system in lenght but I indeed dismissed the fact that it is impossible to jam late missiles . Mr. Gambit even finished his post with , I quote :

    So is it possible to deceive a threat radar via DRFM? Absolutely. Is it possible for a threat radar to successfully counter the DRFM method? Absolutely. The issue for both sides is always — money.

    Wrightwing :

    As for the missile’s ECCM techniques, you can be assured that the types of filtering methodologies discussed, are part of their bag of tricks.

    It is not a part of their bag of tricks , it is their only trick .
    You give missiles more credit than they deserve , Wrightwing 😎

    Btw , I am the only one here to back up what I say with good links when you and Spudman are only exposing your opinions :rolleyes:
    Sorry to say …

    ppp :

    Ah very convenient how France comes out tops in every aspect of your analysis.

    In every aspect ? :confused:
    I only compared some features of Praetorian and Spectra . If you don ‘t like it , write to BAE system and SELEX Galileo and tell them to get in touch with ThalΓ¨s .

    Regarding Thalès AIRBORNE ELECTRONIC ATTACK (AEA + Carbone) ,
    http://www.thalesgroup.com/Workarea/DownloadAsset.aspx?id=2752&LangType=2057
    I know only one comparable (?) system : the EA-18G Growler .

    I would like to know what Company in the UK (if there is one) who works and builds ECM systems designed for aircraft or for testing purpose like the ones used in anechoic chambers . I know one US Company who is doing some top systems : Micro system Inc. (Herley)

    Btw , I heard few years ago that the AN-AAR/56 (F-22 ‘s MLD) could be upgraded to be used as an IRST .
    It is also said in the pdf :
    http://www.lockheedmartin.com/data/assets/mfc/PC/MFC_MLD_PC.pdf

    Any news on this ?

    Spudman :

    The EODAS should have a much better range than this due to a higher number of sensors, larger sensor apertures, and higher CPU processing power.

    True .
    A F-35 might survive such attack but a F-22 will get shot …

    Does anything else even come close???

    Some studies rate the MBDA Meteor better than the planned 120-D .

    Swerve :

    I wouldn’t expect a modern imaging IR seeker to take any notice of flares.

    Correct and it is the reason why DIRCM systems are in the pipeline .
    DIRCM will work nice enough against short range missiles because they are easily detected by MAWS or even by the naked eyes .

    The problem is to deal with long range IR missiles . Will the defender get warned that one is coming ? Then , since the end game is totally passive , will the DIRCM kicks in ? Probably not .
    Imagine a IR Meteor …:eek::)

    Lindermyer :

    IR missiles can be decoyed using flares/ laser systems

    Good luck with flares against missiles like Asraam , Archer , Iris-T , Mica or AIM-9X … πŸ˜€
    Ok with laser but who has a LRF who can do the trick (and in the front sector only) ?

    where you suggesting a mixed salvo an idea which may have more merit

    Yep and it is AdlA ‘s recommandation .

    Open question to all is there currently a fast jet out there utilising a DIRCM system. Im pretty sure its a no, but it can only be a matter of time.

    None so far but it is indeed a matter of time .

    ppp , I know very well how Praetorian works , thank you .

    It is an excellent piece of kit but its accuracy at pinpointing a threat is inferior compare to Spectra and its instantaneous bandwidth search is also inferior .
    Praetorian uses dual superheterodyne receivers where Spectra uses multiple bragg cells channelizers (optical) .
    One is prone to electrical noise as well as phase modulation (oscillation) , it does away with some clever filtering but in doing so , there is a speed loss during multiband search .
    The other does not show this kind of behavior πŸ˜‰
    Also , it can “listen” more bands at once and the recieved signals are purer , if I may say , because the filtering is more efficient .
    Spectra also uses AESA antennas for very fast frequency jumping .

    It is very hot topic and proving the case would take pages and time .
    Just take my word or do some research πŸ™‚

    Ariel works magic against AtoA missiles but it is “noisy” and can be “heard” by others around (mulidirectional jamming) where Spectra is more stealthy because it is using “pencil beam” , thanks to its AESA tech .
    There is no need to “wake up” other radars or RWRs when you try to jam one πŸ˜‰

    Also , wingtips are better used for carrying short range IR missiles than carrying towed decoys .

    Cheers .
