    So how would your SEAD platform distinguish between a cellphone and any mil grade cryptic datalink..?

    Well , i would say that they use different frequency and even if they use the same frequency i dont think a normal cell phone signal is encripted in the similar fashion as a military one. Alternatively, they could use a communication jammer such as tiger pod or AN/USQ-113 to increase the background noise .Transmit datalink signal weaker than that background and you cant communicate. Transmit datalink stronger than that background and you will need more power which a simple cell phone cant provide.Thus, these SEAD assets can now distingush between civilian cell phone and military datalink

    The best method of sniffing radio vaves are dedicated ELINT platforms. They have large recieving antennas to pick up any signals

    I dont think you need big dedicated ELINT platform to pick up radiowave signals. After all, even the tiny antenna in your phone can pick up weak GPS signal from Satellite around 20000 km aways. Radar signal would be load more powerful than that. Data link at short range would be powerful too.

    The notion that a fighter jet could easily pick up radio vaves and pinpoint geo-location source of origin, then just fire a radar guided missile..

    literally what F-16CJ, Tornado ECR, F-4G, EA-18G always do, Russia has loads of SEAD platform too.IMHO Geo locate ground emitters isn’t exactly modern invention.

    Then technically I should be able to pick up said datalink via my grandma’s radio receiver. Cause it’s all electronic signals, right?

    If your grandma radio receiver cover that frequency range and has enough sensitivity then obviously yes , i dont see why not , it may not be able to process and make sense of those signal though due to coding ..etc (modern digital RWR has much wider bandwidth , gain and processing power compared to your grandpa receiver ) .

    Detecting (and geolocating, are you serious?) the kind of data link they use by RWR….good luck with that.

    Yes iam serious , why not ? technically speaking, datalink is just a form of electronic signal not really all that different from radar signal ( moreover unlike radar signal most datalinks are not even designed to focus their beam in one direction ) .And geolocate ground emitter with RWR is nothing new, there a dozen ways to do it.

    Yes. Like I’ve said, it says indicated air speed, rather than true air speed which would have reflected the actual G vs speed graph.

    IAS is very close to TAS at most of the S/L. It can change with compressibility and airpressure at higher altitude. So this graph can be used accurately for S/L performance as G and (true) airspeed is sufficent enough to calculate the turn rate in degrees/second. But unfortunately (IIRC) German manual doesn’t give a IAS to TAS conversion data for varying conditions so its useless for higher altitudes.

    do you think the new mig-29SMT and Mig-35 has better structure limit than those of Mig-29(9.12) ?

    Yes, and ?
    With all respect it seems me that you there are looking at a forest and seeing just trees .
    It is not 5 , 7 or 10 minutes what matter (just the curiosity: how much time it takes to a strike mission on a pretermined target to just take off? ) is the fact that the whole systems is coinceved to be:
    -higly mobile
    – redundant
    -overlapping
    -networkcentered
    – multisensor
    and with CIWS and jammers everywhere to protect batteries and radar.
    So the idea of detecting such asset with a satellite (this what the idea of starfish prime) is simply absurd.
    You have also to consider that limitations they have, like the one of radar horizon need appropriate tactics to be exploited: let’s forget launching SDB from 20K altitude.
    And just don’t try to fly F-22 (but also F-15E) like we europeans did with Tornado during Cold War also.

    IMHO satellite image is more for locating OTH radar which are static most of the time due to their enomous size. Anyway,what iam trying to say is : S-300, S-400 batteries components cannot constantly moving like short range air defense such as Tor-M1 or a ZSU-23-4 , realisticly they would need 20-30 minutes set up time and when they are moving they cant operate as a air defense system(which is a big deal because they can be located when they transmit or launch missiles ).Moreover ,to be networked you need a link between those batteries ,if you want a secretive link you would use electric cable which mean those component cant be located very far from the other , and not very mobile.If you use wireless datalink then obviously those missiles launched and command port are not silent anymore ,thus can be geolocated by RWR.It is always a matter of trade off , nothing is perfect. Then the next thing to consider is that the main role of strike aircraft is not to destroy air defense but rather destroy important structures and strategic targets .Those SAM batteries may be very hard to find if they are silent and moving all the time , but when they do moving and turn off radar then they are not doing their intended job.

    S-300 whose all component can move up in 5 minutes time, have vertical launchers so doesn’t need to stay in open terrain to launch and cross networked one with the other and with all Russia radar network+ maskirovka obviously

    IMHO , 5 minutes for all component set up time is grossly underestimate number , didnt the NEBO SVU take over 20 minutes to set up ?.Moreover, to cross networked those SAM batteries together ,you need some sort of link between them. Which either mean electric cable ( not mobile ) or a data link ( which can be detected by RWR ), another problem is that those link are limited by radar horizon , so even those the SAM launched doesn’t have to be at the same place , they cant be positioned very far from each others.

    3-MiG-29 has 15 deg AOA and 7G limitation above M0,85. It simply cannot have such linear ITR envelope.

    Isnt F-16 also structure limited to 8.5G above Mach 0.65 according to this ? or do i read it wrong ?

    .2-If I am not mistaken I’ve posted 11km altitude sustained G vs Mach graph as well, it shows 3G is attainable at M0,9 40000k feet, and from M1,35+ to ~M2,1+. MiG-29 could almost pull 4Gs at 40k feet M1,9.

    Are you referring to this? ( indeed very hard to compare with F-16 or any western fighter data)
    https://s4.postimg.org/aw6h78bgd/Mig_29g_sust.jpg

    .IIRC MiG-29G manual for German Airforce was readily available on scribd or somewhere similar, it has performance data, but it mostly gives data on IAS, (instead of TAS) and makes it very difficult for comparisons above S/L. It does have some direct tranlations of Cl vs AOA and available G and available AOA graphs from Aerodynamics Manual, which are quite helpful. Unfortunately, I don’t recall the whereabouts of the others. I’ve may not even got them from net too… To my knowledge, in addition to MiG-29G manual, I can confirm MiG-29 has a Russian flight manual, weapons manual, hydrolic&fuel subsystems manual and an aerodynamics manual. Hope this helps.

    I found the manual for German Mig-29 (GAF T.O. 1-F-MIG-29-1) sadly it all about instructions and instruments, cant find any performance data
    I actually found Mig-29 aerodynamic manual, too bad it is in Russian and they dont use the same E-M graph as Western one so i have no idea what heck they talking about lol.

    When looking for Mig-29 manual ,i found this piece
    Is it just me or the graph a bit off ? for example :in intatanous turn rate part , the 9 G envelope of Mig-29 is clearly bigger , why is F-16 evelope labed superior ? , and why the 9G sustain evelope of Mig-29 missing ?

    I have good idea about my knowledge. I hardly impressed with yours.

    Whatever not so surprise that people put you in ignore list and i couldn’t care less if a moron is not impressed by my knowledge .

    I think the real question in this discussion would be “from where the F-22 will operate”??

    Dropping bombs on ISIS? Sure, everyone would open their bases. Dropping bombs on Assad regime? Turkey or Saudi Arabia would support that. But getting into a potential hostility with Russians? Saudis doesn’t simply have the guts. Iraqi wouldn’t want a hostile action towards Russia or Assad and Turkey literally hates US for its PYD support in Syria and the recent anti-Turkish politics in Iraq, and would very much prefer staying on friendly terms with Russia to make its Euphates Shield operation in Syria less risky and troubesome.

    Apart from Israel perhaps, no one in this region would risk hosting US F-22s (or F-15s for that matter). l.

    Fair point but then that would hardly the F-22 fault but rather a political matter.

    Early 1980s Flanker radars were in 100km class. they were 4 times less effective than Irbis which was tested more than a decade. Flanker size and shape hasn’t changed. Fighter radar has limitations interms of heat and powersupply.
    every thing is ground breaking. Russia do have unlimited money. Its Oil/Gas, nuclear power industry and whole government has lowest debts and lowest tax rates of any advanced country.
    where are those EA-18G/F-16J based and what is there range as the latest SAMs will hit the tankers first to put all the fighters out of the way from battlefield. that is without entry of MIG-31BM and attacking from stratosphere.
    without Russian effective bombardment in Syria. the ISIS in Irak would never have been defeated . your 100,00k sorties are either tanker or transport or without weopons. without Russian entry the Turkey behavior towards ISIS would never had changed. that’s why I said all you are writing is nonsense.

    Basically, you cant point out which exact radar system get range improve by 100 times ,you cant give any figures to show that Russian done more sorties or has less collateral damage ,you think power supply remain the same if outer shape doesnt change , you think Russia has unlimited money , along with tons of BS about SAM ..etc.That it , either you are ridiculously dumb or just trolling .Nevertheless, iam done with you.Dont know why i even bothered to talk to you in the first place, waste of time
