    Oh ryly? Czech Rep has some small number of AMRAAMs but hasn’t heard about any shooting. Can you provide any information? Czech Rep has no fire range big enough to fire BVR missile.

    Firing Amraams is not something any European airforce do much of though tbh. There’s usually a campaign with Raytheon at Vidsel every second or so year or so and some of us verify the functionality with the platform.

    When Cz/Hu need to fire missiles (afaik only Aim-‘9’s so far) they go to the Vidsel test range in Sweden.

    AIM-120C5 was integrated for the Czechs in 2005 here’s a text about that. Americans delayed the delivery of missiles because they were cranky or something but they eventually got 24 of them in 2008 I believe.

    We’re not going to give, sell or lease any A/B machines to Croatia.

    Hey, Signatory’s post was good!
    It wasn’t necessary to remove it.
    I’m personnaly exactly on the same wave length concerning Eurofighter.com which pull me on the nerves very seriously on each of its “article”.

    I’m too 200% with EF’s PR bashing better than the plane bashing in its technical characteristics… (as a program it’s more debatable) πŸ™‚

    Yea I erased it myself because A) it had already been up a day and B) I realised it might trigger some flames and it was too much abt EF in a Rafale thread. And I tend to forget smileys.. 😎

    But I guess the story was eurofighter.com’s bashing others while playing the victim card and I wanted to give my opinion why they might behave like that more so than others simply because they don’t have the same history or need to worry about a long term legacy, being accurate etc.

    Afaik the 2 Alenia/BAe/Eads setups for Panavia/Eurofighter has found two countries on the export market in some 30-odd years. Seems imo that EF will eventually go the same way as Tornado and with no new state funded European A/B/E-program in sight and industry/states instead ramping up with the Americans on JSF I feel it’s fair to say we’re talking about a temporary setup. That also influences marketing.

    Development is more at risk than Rafale’s where the French state simply has no alternatives than continuous R&D, yes French do some bits at a faster rate, other bits slower. But it’s moving forward and there’s no other path or whole new 2nd fighter project to split funding on. The countries behind EF is otoh in a financial crisis regarding defense and there’s no clearly defined continuously running state-funded upgrade path. Now the consortium is spending its own money hoping someone down the road will buy AESA’s but so far there’s no move among the air forces.

    I just don’t think Air Forces actually care about eurofighter.com rehashing news of a HMDs (as if it was unique.. in fact core technology from Denel and operational on Gripen without much fanfare) or cryptic talk of (state-unfunded) AESA and (state-unfunded) 2020-visions. Or swings at competitors so its a type of marketing I don’t agree with. Ps. aware people know I criticize Saab when they do stupid stuff too, alot of marketing in this biz is stupid tbh.

    Plenty of life left in the EF project so not saying it’s not going to export new jets again but I think we can take their marketing for what it is and pretty much just smile at it. It’s there to serve journos.

    Shave all that BS off and we (as well as Air forces) see a different story πŸ˜‰

    The “NG” SwAF wants at around 2025, would it have more or less capability than the current NG? I mean, would it still include bigger wingspan, 1000 T/R AESA radar, more internal fuel, more powerful engine etc? I’ve read somewhere that they want to jump straight into GaN-AESA?

    I don’t think they hit the hammer yet so I certainly don’t know either but above all there is a clear focus on sensoring and signature reduction. This comes back again and again. Would not be any less capable. More fuel as fewer bases and jets need to do more while maintaining capability and in turn more thrust to handle new weights.

    Original suggestions back in 2004 (for that 5 year defence decision) was to make C/D with its existing hull (only minor adjustments to strenghten structure if lighter components were not available) into our E/F by adding AESA etc. And by 2020+ the thought was to field a whole new design, more stealthy, as the G/H.

    But really things have changed alot back and forth maybe it will change again but the overall image no matter 2004 or right now, is that 2020+ Gripen need more work on sensoring and low signature. New BVR missile, new cockpit, new architecture and so on is already funded the big decisions is about hull-design how much it should change and good things could be done early with the NG Demo-style of design such as new intakes and a larger/stealthier nose section. Saab is moving in that direction anyways as now reported.

    Question for SwAF/FMV is will that be what they want 2025+ or do they want even more. The jet is just one component in a whole defense so they also talk alot about a “balanced” defense. FMV has studies with Saab and others to see what is possible at certain points in time including fund key solutions like the new Stealth-radome at ACAB.

    Was expected the Swedish military would hand over its plans for Gripen next gen back in March but in the months before that it became more clear it was not happy with the political situation, financial limitation and future capability requirements.

    So this March they said we’re moving the decision up one year but also said they dont really want a new generation until about 2025. And repeated that they want free hands to make the decision. The C/D is new, good capability and upgrades to that system make sure Saab has developers working and will make a next gen possible.

    Political situation is mainly about exports. The SwAF dont want NG to IN/BR specifications but the politicians give these promises to countries around the world that SwAF would buy at least a few. Unfortunately the gov never give the military any more money. Same with telling them to buy 15 Black Hawks asap without adding any new money. Ofc that affects the whole organisation. Not that IN/BR is bad it’s just that they already have C/D and it’s good for us right now and some time on.

    Long story short, SwAF want higher capability NG at around 2025 and if they get what they want it’s not going to look like the “NG”‘s being offered on export today.

    Saab Lansen had a fuselage tank, egg-shaped conformal. When it was empty the aircraft actually flew faster than same jet without a tank at all.

    That is of course unusual but drag is not always so obvious just by looking. In the case of Lansen the tank gave the aircraft a improved airflow as it otherwise was designed like a cigar. Same principle as a airplane wing, it’s not flat as possible to ‘cut through the air’ it’s created for lift or look at Mirage’s huge tear drop external tanks.

    Things like that can still happen today depending on the total end results. Stealth-designs often compromise on flying good vs flying silently for instance.

    But yup generally speaking.. drop tanks on fighters? Draggy!

    No Escape zone comparison says quite a bit I would say… or twice the range with sustained high speed. (Not even talking tech details like the two-way datalink, ECCM, throttling.)

    That turquoise drop in the middle would logically be for amraam.

    Anyway back to the subject, anyone know if SAAB have set up any JVs in India?

    JV and/or strategic MoU’s with TATA TCS, Mahindra Aerospace, Mahindra Satyam, Wipro, BEL, HAL and Samtel.

    More or less. πŸ™‚ Everything is dependent on Gripen E/F to be ready and that is not available yet, or only if any country will order it. All specs and figures of Saab are mainly estimations and I also think, that the lack of experience of Saab with naval fighters, will make it more difficult.

    Ever heard of a thing called sub-contractors? APPH the designer of Gripen’s landing gear has good experience in this field just to name one company. I would also remind you that no MMRCA contender has any experience when it comes to designing and operating a carrier-borne jet for STOBAR operations – the design choice of the Indian navy.

    Well an outsider (for one) called pepe Rezende who had access to the evaluation (I guess you know who he is) was pretty clear about that. And I am sure you know what I am talking about.
    As for the indian comment it was just posted a few days ago and I am sure you have read it.

    I dont read much here.

    Pepe can say whatever he wants, quite often it’s inaccurate. He thought the NG radar was to be supplied by Thales for a long time eventhough that was never the case. The RAVEN radar has not been evaluated by Brazil because the radar didn’t exist at the time.

    RAVEN is not being retrofitted to a existing production jet with all kinds of bottlenecks and limitations that otherwise might arise using contemporary technology.

    RAVEN is for a new aircraft; new hull, new structures, new cooling, new electrical power. The aircraft itself is designed to accomodate a radar like RAVEN and new higher operational requirements.

    If you don’t really know what’s in the works I suppose you’re in for a little surprise.

    Can you prove me it is the real radar ? No. Just to point out that all this debate from aviation nerds is funded on air

    I am pretty sure it’s a prototype radar like Thales (?) and the sensible Rafale fans says. I don’t know why some people call all these pics photoshopped or mockups though which is why I made a point of linking to the prototype. If people wanna judge future systems based on prototypes then sure have fun but don’t pretend like everything is a photshop just because it’s not looking as awesome as hoped.

    I doubt that Selex radar will have exactly 1000 modules so every one is giving a “rounded” figure for marketing/confidentiality reasons. One should be as demanding and wait to count the actual number of modules of the raven radar ! I bet is that some could be disappointed. If I recall well raven modules were hidden behind a red plastic cover when shown to the public….Perhaps they fear to give the real number !

    Beside with only one engine there are certainly other limitations for the future gripen radar in terms of electricity production. The raven radar was also deemed as the “least developped” by the indian and “doubts about the performance” during the Brazilian eveluation. No wonder there is some jealousy over the RBE2 AESA:p : It is ready for delivery now. The fact that the French air force wait due to budget constraint is a different reason.

    And I agree that nothing prove that the radar shown is the actual radar. This is only speculation here.

    Brazil didnt evalute the radar. Selex and Saab have the most AESA experience in Europe and know what they are doing. They both export AESA radars to both USA and France mind you. Gripen NG is designed with added cooling and electricity in mind for the new sensor suite. That is no problem.

    I have asked SAAB if there was any truth to rumours on a Raven radar with less than 1000 TRM’s and they said there is no chance whatsoever that the radar being offered will have less than 1000 TRM’s. I got it in writing.

    The array can be looked at on SAABs website without the cover. It doesn’t use the visually separated TRMs like RBE2 AESA so a count is not possible. I am sure you have seen Vixen arrays before.

    This and this RBE2 AESA has the same low TRM count. Are they both mockups?

    radar blockers for a single engined aircraft with a Y-shaped intake? never heard of that before. got a source for that ?

    JAS 39 doesn’t have Y-shaped intakes like that. It’s impossible to see the engine face from the intakes up front. The engine fan sits behind a ‘wall’ with split L/R-openings (where radar blockers sit (photo below)) to each S-like shaped intake duct canal.

    As for MMRCA, India seeing a need to have many light/medium sized multirole fighters with affordabel price. These are the ones they intend to really mass produce to expand squadron numbers. SU-30 and ‘PAK-FA’ making up the heavier side. It would be different if India only saw a need for heavy fighters but now they see a need for a large number of light/medium jets and Gripen comes out of the box as one of, if not the most integrated multirole jet in that spectrum for a good price.

    Lots of weapon choices, recon options, maritime strike, experience with mig-21/29 conversion.. more flight hours for the money. Fewer parts in the logistics chain. Spending less on MMRCA integration work, flying and ownership cost also means more money towards LCA/AMCA and other programs. So if the jet can do the required work, then there’s no reason to pay extra.

    About the jet, restrictions are there over safety and cost issues that the customer (SwAF) requires as they today see them as more important than to take delivery of a jet that requires more training and budgeted flight hours. Saab does state they can offer other settings to other customers, but expect more flight training. It’s also worth to keep in mind the FCS issues Sweden initially had and the bad press etc over the program. Rather do this safe than be sorry..

    This aircraft as well as other weapon systems in use by Swedish military operates with lower performance in this forseen period of peace than its actual capability but there’s both operational and non-operational switches to uprate the systems when the customer has a change of mind. In Gripen this is mainly on radar, engine, ews and fcs.

    I may point out that no one has lost his life in a Gripen. And that is despite heavy budget cuts over the last 20 years. Only recently has flight hours began to move up again.

    Obligatory, Sign, Signatory, Maskirovka and other Swedish posters (Loke is Norwegian?) might be interested in going through Ola Ringell’s lecture on the Gripen’s flight tests right from A/B to C/D to now E/F

    Just go to the 1:19 mark and the lecture starts from there.

    BTW, check out slide on Gripen Operational envelope

    The AoA limits are +26 deg / -10 deg

    And this coming from one of the Gripen’s Test Pilots, I think we can say for sure that nobody will contest it.

    OK. Why would anyone contest them? Those peacetime AoA numbers were mentioned 10 years ago by the SwAF in Airpower 2001.

    mmm..this is an interesting comparison..

    ermm..what does it mean there is no IFF in the swedish greek and mexico ones..:confused:

    Sweden doesn’t even operate EMB-145.. a clue on how accurate this comparison really is? ESM/IFF is integrated in the Erieye SSR.

    It seems the first Gripen NG prototype will fly in March.

    Thanks to Signatory!

    Ty. Well I am not 100% sure HΓ₯kan implied “fly”. He used 39EF take off.. Now there’s two tracks to this program. Gripen NG Demo has been in the workshop since uhm 5 months or so getting modified. Then there’s the ‘true’ NG jets built to production standards with new from the ground up drawings and parts. The latter one supposed to enter assembly next month for flight early/mid 2012.

    Unless they tweaked the schedule.. they have often been sneaky like that. Even Demo 39-7 flew half a year earlier than communicated. But realistically, if we’re looking for a flight soon it ought to be the modified Gripen Demo to SwAF EF requirements. It’s also time for some home market PR stuff..

    We shall see.
