    see this pix. Su-35 can carry 4 R-77SD there. The missile that outranges Mica by 30km. and this without considering platform difference.

    only 2 r-77 in the picture :confused: and why rafale carry mica instead of meteor

    The utility and benefit that modern AESA’s provides has less to do with BRUTE RANGE and more do to with the TRICKS it can pull off, such as LPI features, Software based modes, and EW ability..No point in having a huge radar which makes the entire point of stealth redundant…Emission Control is a main design feature of modern 5 th generation fighters…So LPI radar with smart passive sensors is the way to go..Not brute radar power for maximum range..

    this is true , but it always nice to have some more power dont you think

    Irbis E is tested with thousands of flights. EF will integrate 1426 T/R module AESA in 2015. and than they can reasonably make claim

    ok quite reasonable point ๐Ÿ˜€ but i dont think producer can’t calculate power of their radar

    It doesn’t. It is just a marketing brochure number.

    btw i found this also support that ef-2000 have rcs very low and strong radar

    According to a calculation by a senior EADS radar expert, the Captor-E, which will use 1,426 T/R modules and is scheduled to be integrated onto the Eurofighter Typhoon in 2015, is capable of recognizing the F-35 at around 59 kilometers away.

    He acknowledged that the chance is high for the F-35 to detect and fire missiles first against fourth-generation jets, such as the Eurofighter or Boeingโ€™s F-15, but claimed that the latter are capable of dodging missiles and successfully counterattacking at such a long range.

    His calculation shows that the F-35โ€™s APG-81, which allegedly has 1,400 T/R modules, will be able to recognize the Eurofighter or semi-stealth fighter at 120 kilometers or farther based on the assumption both radars have the same capability.

    APG-81 AESA (F-35A/B/C)

    For RCS 0.0001 m2 class target: 16 km+
    For RCS 0.001 m2 class target: 28 km+
    For RCS 0.1 m2 class target: 90 km+
    For RCS 1.0 m2 class target: 160 km+

    For RCS 5.0 m2 class target: 240 km+
    For RCS 10.0 m2 class target: 285 km+

    CAESAR AESA (EF-2000 Tranch3, post-2015 with 1,500 T/Rs)

    For RCS 0.0001 m2 class target: 18~21 km+
    For RCS 0.001 m2 class target: 32~38 km+
    For RCS 0.1 m2 class target: 104~122 km+
    For RCS 1.0 m2 class target: 185~216 km+
    For RCS 5.0 m2 class target: 278~324 km+
    For RCS 10.0 m2 class target: 330~385 km+

    so either ef-2000 have bigger rcs or f-35 have strongger radar ( i mean compared to advertise ) :confused:

    Korea tried to buy PAK-FA but Russia turned down.

    really ๐Ÿ˜‰ i thought they want to buy f-22 but then can’t and decide to purchase f-35 instead

    :p to be honest i dont know ๐Ÿ˜ฎ , as the same can be said about irbis-e but may be u right about this

    You ‘re right DJ but we should not put “detection” and “jamming” in the same basket , only the former is the RWR ‘s job .

    It is true that AESA and to a lesser extent PESA radars are more robust vs sidelobes jamming than older mechanical radars .

    Everybody ‘s having the same problem : the enemy ‘s data fusion , AWACs and 3rd part targeting .
    -First example : your RWR tells you that a big , powerful and rotating radar (AWAC) is at your 11 O ‘clock , 300km away . Even if you have a powerful EW suite , you may not have the needed output power to jam such pulse trains signals that far away . How are you going to hide if you ‘re not a true 5th aircraft ?

    in theory deceptive will help if that a normal awacs radar , not lpi

    -Second example : your RWR tells you that for a micro second , an AESA radar (at your 11 O ‘clock , 110km away) painted you , then , nothing more from your RWR . 2 seconds later , your MAWS tells you that 2 missile flashes are detected at your 2 O ‘clock (!?) , 100km away . Then , it ‘s the other way around , radar painting at 2 O ‘clock and missile flashes at 11 O ‘clock .
    You ‘ll better be able to handle those threats and your EW suite capable of very precise multithreat jamming .

    multi threat jamming is extremerly hard especially when using deceptive jamming ๐Ÿ˜€ noise jamming do the job better but affected by hoj

    moon_light :

    Not so , not so . It is detectable by AWACs , the problem is : who ‘s talking to who ?

    Cheers .

    i was talking about directional datalink

    but then there is missile weight.
    Basic R-77 or RVV-AE weigh 175 kg, and it has 80 km range.
    Ramjet version R-77M1 or RVV-AE-PD weigh 225 kg with 160 km range.

    If we assume 50 kg is for warhead, seeker, electronics, body, wings, actuators, that would leave 125 and 175 kg for propolsion. If you look at engine weight efficiency in km/kg, you will easily see how Ramjet is more efficient (~42% more in this case).

    However if we make same assumption (50 kg for anything minus engine) for Meteor, it would only leave 135 kg for propolsion. If it has exact same propolsion and aerodynamic layout of -PD version, it would have approximately to 135/175 = 60% range. Obviously on smaller missile, drag would be lower, but so does mass flow to the engines, in short without improving design thats about it.

    :p well western tend to make missile with smaller radar , warhead than russia (EX : agm-84 vs p-700 ) and as the meteor is smaller than R-77M electronics, body, wings also lighter ..etc , and like you have stated lower drag , the point about the air flow to the engine we have to consider the design intake of meteor vs R-77m

    i can only found this about EF-2000 future AESA radar

    CAESAR AESA (EF-2000 Tranch3, post-2015 with 1,500 T/Rs)

    For RCS 0.0001 m2 class target: 18~21 km+

    For RCS 0.1 m2 class target: 104~122 km+
    For RCS 1.0 m2 class target: 185~216 km+
    For RCS 5.0 m2 class target: 278~324 km+
    For RCS 10.0 m2 class target: 330~385 km+

    it seem little bit weird caused eurofighter dont have bigger random than F-35 , also not bigger but the radar range here seem to match su-35’s irbis-e ๐Ÿ˜ฎ

    according to this ancient New York Professor Su-35 and Rafale are even but typhoon better :diablo:

    i read that too but the su-35 tested dont have RVV-DB and irbis-e so :confused:

    hopsalot :

    I am not responding for Mercurius but you are most probably alone in this world to disagree on this matter . You can ‘t cheat physics . If one listen the whole X Band (or any Band) with a low enough threshold , not a single signal on this Band will be able to hide .
    hopsalot , why do think everybody is trying to minimize its radio emissions ? Why most fighters try to get 3rd part data before to do anything else ? Why Fighters like F-22 , Rafale , Typhoon , Su-35 , F-35 , Pakfa , J-20 (?) rely primarely on passive sensors first ?
    Because as soon as you start emiting , we can catch you , however “LPI” you are . We only need to listen to the right radar Band .
    .

    well in my opinion LPI AESA compared to normal radar is like stealth fighter compare to normal fighter in term of RCS so it is extremely hard to detect but still detect able at certain range , however 3rd data is completely undetectable that why fighter like rafale , f-22 ..etc prefer to receive datalink to turn on their radar ๐Ÿ˜Ž , another adavantages of that is AWACs radar can be much stronger , jamming resistance compared to fighter radar ๐Ÿ˜€

    It was a serious of general performance evaluation; climb, acceleration, turn, roll, avionics, radar, an AMRAAM firing(Not done on the F-35 and the F-35 received zero), micromaneuvers, visibility, etc.

    they not calculate RCS and the point about about AMRAAM firing obviously not fair for the F-35 dont you think ๐Ÿ˜‰
