    I am also interested in it, because Thales is one of the possible co-development partners for Tejas MK2 AESA radar and wonder how good it would be for it with a diameter of 600 to 650mm and if that could be coupled with MMRCA?

    But what does it matter how many modules Thales puts in the RBE-2?
    As discussed, modules are limited by array area, since their wave-forms now need more separation than the physical modules. So who-ever co-develops Tejas Mk2´s radar will have the exact same constraints… Tilting the radar face gives more surface area, and if you want more ´shoulder targetting´ capacity, you have two approaches: swash-plate swiveling of tilted frontal array or discrete ´cheek arrays´ (which don´t need to be turned on when only looking forward, and only one cheek array would likely be turned on at the same time… possibly the frontal array itself isn´t needed during maximal cheek angles).

    I suppose one could claim that Thales (and American manufacturers) may offer more expertise in cheek-arrays, since that´s their planned direction to evolve RBE-2, and Selex/Saab may offer more expertise in swash-plate swivelling, but all of those companies would likely be able to competently help implement either approach… I doubt the physical swash-plate is itself overly problematic, it is processing the data that is the main point. That, and the price each wants, seems more relevant than # of modules in their production radars (or vaguely near to production, in case of Saab and Selex).

    As for the Zhuk-AE, there is no reason to believe that its back end is in any shape or form larger than it used to be for the MSA Zhuk-M (and the latter obviously fits inside a normal Fulcrum nose no problem at all). What probably led to the test array being smaller is power consumption and cooling demands of the less advanced prototype T/R modules which the MiG-29 generators and cooling system were unable to cope with.

    Agreed, very likely about the cooling requirements.
    I think you misunderstood my post slightly about the back-end, I never suggested it was bigger than the previous -M model, but that the LATEST Zhuk-AE has a smaller newer back-end than the previous development model -AE, which was using the -M back-end AFAIK.

    Anyhow, I´d be more interested in actual capability demonstration, like the GMTT/A modes being developed sooner for UAE, along with it´s actual SAR resolution + range.

    Has anybody heard new mumblings about FX-2 contender home countries´ proposals for participation in C390?
    I think I read of a concrete commitment for 10 air-frames from France, which isn´t huge, but a start.
    It seems that if France organized it´s planes as an open EU/NATO transport pool, ala C-17 but cheaper, that would make it most attractive for other countries, especially smaller ones but every one counts, to join in (and (co)buy more planes). Not the just the French numbers alone, but firmly establishing EU/NATO partnership co-dependent on Brazil would seem a strong offering… ???

    The array SEEMS very VERTICAL, i.e. not canted backwards.
    Supposedly the space of the back-end was a factor in increasing the array size/number in Zhuk-AE. To claim that a small nose / array size was NECESSARY because of carrier landing seems far-fetched, given the Super Hornet and even Mig 35 w/ Zhuk AE. It may well be that the back-end of RBE2 is taking up more space than a modern designed one would take up, and this impedes on the space of the array… In any case, I think the main customer (AdA/MN) was happy with the result and didn´t want to make other trade-offs solely to increase array size/number… and that certainly isn´t the only/defining factor of radar capability.

    I do wonder if re-doing the nose would be on the cards for the ´stealth Rafale´ (not in sense of F-22) upgrade/block cerca 2018+… Certainly I think by then (say, with GaN modules) more elementes will be able to packed closer in the first place… And perhaps if the back-end is redone it can open more space as well (possibly relocating portions to a different location entirely, since I doubt they really need to be physically adjacent). I think it´s pretty clear that the back-end is the area MOST amenable to incorporating the latest-greatest in CPU minituarization, etc, and in Rafale´s case that is held back by commonality (/no new funding to re-develop) a new back-end compared to the one that powered the PESA. Personally, I really think Dassault/Thales would have been better off partnering with Saab for example, so that Saab´s back end and swashplate could have been cheaply integrated onto Rafale… That would have meant Saab designing their back-end to be compatable with Thales software, and their own software enhancements sitting ´on top´, but that seems perfectly do-able to me, and both products would have benefitted IMHO. (It´s not like NOT cooperating with them left Saab with no options)

    I feel like Russia should join India´s AMCA as a development partner.
    Let India lead the program, if they fund the majority of it, developing whichever parts they wish.
    Russia would develop sub-systems within it´s remit, likely playing off of PAK-FA developments. Developing Russia-specific variant without certain foreign sub-systems that India may select, with full access to the design to allow full Russian production / export at-will (within JV agreement / licencing fees to HAL).

    Anyhow, that´s another thread… 🙂

    Except they`re explicitly saying NO.
    Isn`t `the customer is always right` an American phrase? So why the trouble accepting direct Indian government statements?

    It isn`t really hard to see why, given they will be developing/producing AMCA in the timeline that they might acquire F-35,
    after inducting MMRCA and PAK-FA/FFGA along with upgraded MKIs, 2000-9`s, and Tejas Mk.2.
    Personally I`m interested to see what AMCA turns out like, as it essentially share`s the F-35`s role without the STOVL compromises.
    If America has any goodies to offer, they can offer them ala carte for India to integrate on PAK-FA and AMCA if India so desires.

    US client states in MidEast like to buy American (or European), US/NATO has C-17 and A400M and has a very expeditionary focus so isn´t going to give up rough field capability, Latin America has C390 in the works (with industrial work being shared around) besides Russian and US planes and likely isn´t going to want to give up rough field capability given their large land areas and few airbases, SE Asian nations and Korea (/Taiwan?) MIGHT have a use for it, but again lack of rough field capability means it can´t be used once an air-base is out of commission… And I´m also not aware that C-2 has really been designed for the full spectrum of military transport operations, e.g. air-drop, that A400M has… So I don´t think those countries would want to go for it either.

    The thing is, most other countries in the market for this size of an airlifter plan on using it in war-zones. I don´t think Japan is really planning to do so, at least with the same urgency that other countries make these plans. For Japan, it´s basically an internal airlifter and for ´civilized assistance´ (for which longer range is nice), but not for real wars where nice landing strips aren´t always assumed. And it´s not a matter of simply not being able to use a given strip AT ALL, but using the same strip many times, where C-2´s footprint will just tear up a lesser strip in no time. Sure, you hear about Japan´s military shifting posture, just like you hear rumours of export bans ceasing, but that´s not a reality yet, certainly not to have formed the requirements of the C-2.

    *IF* Kawasaki can see a viable case for establishing world-wide servicing (at least helped by the commercial engines),
    I could see a truly civilian role in large-volume ramp cargo transport, below the really big Russians, but that´s it.
    If they did think it was viable, I think there would have at least been some squeaks about getting a civilian-only export licence, so since I haven´t seen anything of the sort, I assume they aren´t trying. As Sens said, Kawasaki/Toyota are likely happy with the profits of fully-funded government work that fortuitiously increases their own aerospace capacities in general… Investing their own money to commercialize it may not really seem the best investment opportunity for them.

    But it seem a reasonable success by Japan´s own aims, commonality with PX helping economy, and maintaining Japan´s capacity in aerospace. Certainly not a bad plane for what it´s focused on.

    There was also talk of Greece acquiring UAE & Qatari M2K-5/9’s, replacing EGM’s in lieu of upgrading them. Greece might be happy to sell on the EGM’s to Brazil (for a lesser price than the -5/9’s). Obviously those aren’t going to be comparable to -5’s (Link 16 capabilities, etc), but it could be enough for Brazil to tide it over until FX2 happens…?

    I was using the most recently agreed deal as the frame of reference to compare the scenario where 13 airframes could be diverted/sold on, since if the re-sell deal doesn´t happen, EADS is still delivering the same (reduced from original contract) amount of airframes.

    Definitely there´s more history that doesn´t reflect well on EADS or it´s profit share-holders by proxy. At the least, it´s a scandal that not ALL of the additional monies/ erased airframes were structured within the loan that will potentially be payed back from exports. If EADS ends up exporting (/licencing) a ton, that´s all profit for them.

    I don´t doubt that what you write is very representative of Australia´s experience with US/Boeing,
    but I think the actual current situation of the US and it´s relation with Brazil is somewhat relevant as well.
    Problems with the F-35 program mean USN and Marines NEED to receive new Super Hornets, this is not like when Australia inducted it´s SH when the USN thought it´s F-35 schedule was still workable and wasn´t interested in further ´current gen´ SH when ´next gen´ was around the corner.

    As well, your mentioning of Boeing´s open-ness to new capabilities in the platform seems to ignore the basic features of FX-2: Tech transfer means Brazil will be able to integrate WHATEVER feature it wants to, and it will, as it´s developing new short-range, long-range A2A missiles, ARH and ASh missiles, as well as smart ground munitions.

    Holding out NGJ as an option, when it´s clearly not part of Boeing/US´ offer given it doesn´t exist yet, is absurd… If US is so willing to export NGJ to Brazil (which there´s no evidence of, and the US has given the absolute minimum on SH/APG-79 ToT so far), there is no reason that Brazil cannot integrate it with WHATEVER platform it selects. If Brazil is to believe that the US is so fickle and jealous that Brazil can only expect favorable treatment if it sides with the US in every decision and tender, then that just isn´t really a good sign for the US here because I can guarantee that Brazil is not planning on playing poodle to the US like that.

    The Iran case is exemplary of this, that Brazil accepted US and French diplomatic drama at face-value, that a enriched-fuel exchange was desirable with Iran, but when they actually arranged that with Iran and Turkey, the US and France could not accept the very thing they previously advocated. To Brazil, this say the US (and France in this case) does not consider it´s word inviolable, and in fact does not act with whatever ideals it claims (which is really the same thing as following it´s word). So promises of ToT and non-interruption of export licences (considering not every component is going to be produced in Brazil) are rather impacted by that sentiment.

    Dilma may well decide that SH is the best choice for FX-2, but it will be on the basis of up-front ToT and face value, not dreaming of what goodies the Americans will continue to provide in perpetuity.

    Germany is still ensuring that Airbus is paid for the exact same number of planes.

    Airbus is clearly not RELYING on exports to validate the program for them, rather the initial partner orders which is unchanged by Germany´s move. Although these 13 planes are presumably planes that Airbus would otherwise sell (in addition to partner orders), Airbus actually agreed to payback (emergency negotiated) loans from the partner states based on export sales…

    So if it makes alot of exports it pays back all these loans, if it makes less export sales, it may not pay back all of the loans. If there´s absolutely no exports besides these 13, I guess this could reduce the loan-repayments (to ALL partners, not just Germany) by the price of 13 planes, but in reasonable export scenarios (which is what the partners are assuming if they expect their money back ever) 13 airframes just doesn´t really matter that much. It also seems pretty reasonable that Germany and Airbus could write some contract so in a low-export/low-repayment scenario, that other partners aren´t penalized by Germany´s sale cutting away from exports.

    The given reasons I can´t see why Rafale is completely out.
    France´s policy towards Iran is clearly toeing the US´ line, so isn´t worse off than US there.
    EU trade agreements not working out ideally doesn´t seem much worse than Brazil´s opinion of US currency games… If anything the US is worse off in that case, and any price advantage of theirs would be seen in that light, I´d think.
    I think Gripen´s chances are still good… But I also wonder if it IS re-opened, if Russia has an opportunity with Su-35. They may be more serious about tech transfer, and if they are I think they would be cleary seen as lower risk vis-a-vis political problems with US.

    …We´ll see…

    Boeing withdraws from Indian midair tanker tender
    Sounds like they don’t want to fund the necessary development work on the 767 unless they actually win the KC-X.
    Which is kind of strange, between the Italian and Japanese tankers, how much development work would an Indian bid actually take?

    Well, that makes me think they are bidding a more heavily modified bird for KC-X… One that they don`t want to be contractually obligated to deliver to India for the contract price if KC-X ends up not going their way. Presumably a more heavily modified tanker`s raison d`etre is doing it`s (KC-X defined) job better, but even still Boeing feels there`s a non-zero chance they will lose KC-X, and don`t want to be on the hook for delivering it to India. And apparently they don´t believe the same tanker they sold India and Japan would have a chance.

    Could the side-lining of Jobim be the true aim in this though?
    I.e., delaying FX-2 is just to prove the point and re-inforce the message,
    but challenging the decision per se isn`t as relevant as reducing Jobim`s ongoing role in other matters?
    …speculations…

    It seems like even if MiG has given up on MiG-35`s chances, some Su-35`s could be sent, which essentially would leave the point that India can just induct further more MKI (Mk. 2`s with Su-35 tech if they want).
