    Given decades research and billions dollars budget, i doubt that they need luck

    Airdefence manufacturer spent even more than aircraft manufacturer. Just look at size of factories. Aircraft manufacturing is very labor intensive process . Adding billions does not add to capability. Look Boeing 787/777 it need external Russian help to achieve may be 20% efficiency. Spent same amount on airdefence missile and you get 1000% improvement and those very visible example. Effectiveness of R&D start from education system and centralized continuous leadership.

    both radar and missiles are getting compact. progress is very visible like tablet pcs. on otherhand the so called stealth planes are draggier and heavier need larger noiser engines. plus practically zero progress in aerodynamics. computers can easily predict the performance while missiles hide in tube no one knows real ranges and speed unless export client confirm it.

    Russia can buy more advanced UCAV from china if there is need for it. Most of stuff that Israel produce China also produce in much greater quantity and performance.
    the trade ties have been declining with israel. they dont produce stuff that of interest to Russia.

    That’s incorrect. Lockheed Martin is formally barred from marketing the F-35 in any form to Middle Eastern customers (barring Israel obviously). Any presentation requires DoD approval and that’s not in coming.

    israel, china and nasdaq.

    Brazil & India are different cases, in that the US is forming long term strategic partnership with India, driven by geopolitical developments in Asia. Including, but not limited to, military sales, intensive joint exercises and intelligence sharing. Which is also why there is a dedicated India cell at the DoD and why the US Congress passed the US-India Defense Cooperation Act through the NDAA 2017 bill. Brazil meanwhile, a benign power in a generally peaceful region of the world, is only peripherally involved in the power politics in Asia.

    how exactly brazil and india different cases. india willl find significant constraints on use of US systems the more it depended on them and import based economy means as the equipment ages the cost of upgrades and maintainance rise. see the Taiwan F16 upgrade without engines and they only 20 year old not 30 age when india usually upgrade stuff.

    Numbers (exact ones) out today for the RN/RAF (https://www.nao.org.uk/wp-content/uploads/2017/03/Delivering-Carrier-Strike-Appendices-three-to-five.pdf)

    Readers Digest:
    Development, acquisition, training and initial suport for five years, plus 48 airframes for 9,132 billion pounds.

    Not too bad
    Cheers

    not too bad? have you looked at oportunity cost . the money spent on F35 will add capability in post 2020 timeframe and in mean time uk standing as military power will go down and this will have very negative impact on rest of economics. there is professor at king college he put it this in his tweets.

    The T/R modules on the latest Erieye systems have more than double the power efficiency of the earlier versions.

    netanyahu went to china and keep repeating word biggest.

    Compulsions surrounding Russia and Israel over Syria
    Unfulfilled promises
    However, we know that promises in such uncertain times cannot be reliable, and often do not get fulfilled. Moscow has promised to reduce the presence of Iran and its allies later on, but the realization of such a promise requires explicit international guarantee

    my opinion is Israel has taken money for ousting Iran from syria and Russia has share in it so all this song and dance as these articles keep proping up.

    these are stories from 90s mixed with current . ukraine export very little and most of it were engines from soviet times. Chinese made export AWACS is more advance than Sweden Erieye.

    Lazy to load the Radionix’s proposal for N001 radar of Su-27 so I give you the link of their proposal for N019 radar of Mg-29. They both are exacly the same.
    http://wartime.org.ua/23321-modernzacya-rlpk-mg-29.html

    They can make all the proposals but I doubt Chinese using missile whose electronics are 20 year old.

    The 2017 Russian Defense Budget is out, according to Janes it got a massive slash of almost 26% by comparison with 2016!
    If so expect salami slice cuts across the board, it will be “interesting” to see the efect on the VVS.

    I doubt they decrease budget unless there is some reshuffle in procurement to export first and delay procurement for more advance systems. Flight test of A-100 start this year.

    They confirmed and proved they could do that even better than “Russian well-known by-pass concept of N001 upgrades”.

    If Chinese still using R-77. It’s either new import or completely changed inside with Chinese systems.

    these are in microwavejournal. i dont see that much independent swedish stufff now. they are part of EU and once it go to EU it does not move forward.

    Because that’s all their manfacturers can produce with incredibly obsolete foundry equipment purchased from European countries 10-15 years ago (Russia doesn’t produce its own mmic production equipment).

    Jo has already shown us proof with the photos of the equipment from inside the foundries.

    Cute, that “gun” is a truck sized, poor man’s laser. 6km range… impressive… back in the 80s.

    No can’t show any proof as he no nothing. That Obsolete European foundry are past tense .
    Russia built 300M foundry at Mikron for chips and 200mm at Angstrem for communication equipment. Micran and Istok are the MMIC manufacturer. Your confusing mmic foundry with chip foundry. The mmic foundry does not cost more than $100mm. The chip foundry upgrade cost about $1b cost and new one about $5b. so spare your bs to some one else Just to give you costs clue Russia 3.5 generation nuclear reactor cost $3b and Russia built 4 for China and building 10 for itself.. One French or Westinghouse reactor cost $15b and is years delayed. You can’t compete with Russia on construction new foundries or factories

    GaN’s higher efficiency and heat dissapation gives manufacturers the ability to increase input and output power, decrease size (higher power density) or increase bandwidth of the output of the high power amplifiers used within the transmitter part of AESA TRMs.

    Cree is the undisputed king of HPA technology and now have Lband HPAs just 2x1cm in size that run at a whopping 900w output. They are only available for purchase by US Lband radar manufacturers. US is also continuing their stealth fighter program even though they are years ahead in Lband component manufacture.

    Current Russian equivalents are still prototypes, run at 40W are far less efficient, lower bandwidth, and are multiple times the physical size of the Cree 900w.

    European, Korean and Japanese manufacturers trail behind Cree an Triquint.

    Russia has microwave gun so why will the modules have less power.
