    Better EW system… Thanks for the laughter, you made my day

    I am as big a fan of blind nationalism as anyone, but you are really taking things to extremes.

    The Falcon Edge system was designed and built to the UAE’s exceptionally demanding requirements and is second to none, and ahead of Spectra… and you don’t have to take my word for it. Just ask the UAE:

    This is surprising in some respects as, although the Rafale performed extremely impressively during recent operations over Libya, the UAE has made no secret of the fact that it requires an aircraft significantly more advanced than the current Rafale versions in service with the Armée de l’Air.

    It specifies a longer-range active electronically scanned array (AESA) radar with ground moving target detection and tracking (GMTI/GMTT), ‘interlaced’ air-to-air and air-to-ground modes, a more capable version of the Spectra electronic warfare suite, integration with MBDA’s Meteor long-range missile and, crucially, with more powerful versions of the Snecma M88 engines, producing more than nine tonnes of thrust (about 1.5 tonnes more than the current engine).

    Over time, Meteor integration and some AESA and Spectra improvements have become a funded part of the core Rafale programme, but the Armée de l’Air has no stated or funded requirement for a more powerful engine, which the UAE reportedly still wants and which many analysts believe would be essential for long range air-to-ground operations with heavy weapons in the region (and certainly to allow carriage of a three-missile heavy strike loadout using the Black Shaheen). Nor are planned French radar and Spectra improvements believed to be sufficient to meet UAE requirements.

    http://www.arabianaerospace.aero/uae-s-rafale-deal-is-no-mirage.html

    While on the subject of upgrades necessary to bring the Rafale up to the standard the UAE is currently accustomed to in their F-16 Block 60s… the UAE also believes the Rafale to be under powered.

    French air force pilots interviewed at Solenzara say that the current engine power allows them to fly all of their missions without limitations, and that on a seven-hour mission to Libya they can cruise at Mach 0.9 on a 50% power setting with a full ordnance load. They also say that operations in the United Arab Emirates, Afghanistan or other high-temperature areas have not shown a real need for more power, although they all agree that it would be nice to have.

    One Rafale pilot at Solenzara who has flown in the UAE remarked that one reason they want a more powerful engine is that its pilots are now used to the latest F-16 Block 60, which is essentially a small airframe built around a very big engine, and so find the Rafale underpowered by comparison.

    http://www.defense-aerospace.com/article-view/feature/126031/**france-readies-rafale-upgrade-for-2012.html

    Now don’t take this the wrong way. The Rafale is unquestionably an excellent aircraft, but you are being delusional if you think its poor track record against the F-16 is a product of politics or budget buyers.

    The Rafale lost the UAE deal on quality, and has failed to secure the deal to replace the Mirage 2000-9s on quality.

    The UAE are demanding buyers and as much as they would like to maintain two suppliers for their air force, they aren’t willing to accept anything less than they are currently accustomed to do so.

    What about using GPU’s instead of CPU’s to do the hard work? I see SAAB has been looking into as we can see in this link

    http://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CC8QFjAA&url=http%3A%2F%2Fuu.diva-portal.org%2Fsmash%2Fget%2Fdiva2%3A292558%2FFULLTEXT01&ei=1tkMUbuKBoKq0AWr1IGoCw&usg=AFQjCNGla1UVcuHYnAlcMkv_eA4jM0_uNw&bvm=bv.41867550,d.d2k

    I’ve no idea what it all means though as i’ve not had the time this morning to study whats been written in the link.

    Computational power is always useful.

    Better computers will help, but there is no way around the fundamentals of electro-magnetic waves

    Radars are not going to keep pace with computers. THey never have, and they aren’t about to start.

    First off i think the thread should be named F35 debate thread part II..

    There are a few ways to improve the range.

    1. More power
    2. Higher resolution
    3. Using narrower search (using “beams”)

    Modern processors can work on #2 while AESAs can work on #3. This means that as long as there is a return/echoe (as in ANY return) it in theory can be filtered out by modern processors (it could be solved by tracking everything and only displaying confirmed objects).

    But currently the systems are limited by the “noise” levels, every echoe above it will be tracked and every object below it will be ignored. Current radars try to lower the threshold, but thats just the first babystep.

    But by tracking the objects below the threshold and display whats been filtered out it in theory gives the possibility to extend the radar range by a large magnitude.

    Are we there yet? No. Will we get there? Most likely yes.
    The F35 has the highest Gflop rating on any modern fighter jet. In a few years when we will see hundreds of Gflops in most fighters we will start to see real filtering. AFAIK F35 will be the first to reach that level (2’000Gflops).

    Data filtering is pretty straight forward, but it requires a lot of CPU power. Just for comparison the F22 handles about 20Gflops and an iPhone 4S gives 51Gflops while the F35 offers 2’000 Gflops. Thats enough for advanced filtering.

    More computing power is always nice to have, but not all problems are fundamentally about computational power.

    Which would you prefer, the Hubble Space Telescope or a backyard telescope hooked up to a supercomputer?

    Physics is physics and all the computational power in the universe won’t change the fundamental drivers of radar performance.

    Getting to the bottom line… better processors can help, and AESA’s are a big leap forward from earlier radars, but radars in general are not going to improve with computational power.

    Rafale and F-16 are not really comparable, in the sense that they belong in different classes. If you want to compare Rafale to other planes I think F-15, Typhoon and SH are more relevant, however the F-15 is of an older generation, thus really Typhoon and SH compare to the Rafale, in terms of similar capabilities and growth potential.

    The point is simply this; most countries don’t need the capabilities of an F-15, Rafale or Typhoon. Thus they go for the cheaper F-16 instead.

    Not really comparable? Lets be serious for a moment. Not only are counties comparing the Rafale and the F-16, they usually pick the F-16.

    …and don’t go thinking that it is some kind of a budget vs capability kind of trade-off. Something like an F-16 block 60 is hardly a buget aircraft and the UAE is hardly a budget buyer.

    The UAE picked the F-16 over the Rafale for some pretty simple reasons, it was more capable. It had a better radar, a better EW system, and a far better selection of armaments.

    In Morocco the F-16 was cheaper, but again that doesn’t mean it required compromises in capability. Sometimes cheaper just means a better deal.

    Much of the reason the F-16 has been able to offer so much more capability for less is because of the scale of the program. The Rafale is currently being produced at a rate of 11 aircraft a year… that means 11 radars, ~22ish engines, etc. It drives up the price of everything. (One of the big reasons the Rafale win in India was so suspicious to the EF program… )

    Actually it was fairly well known at the time (by anyone who took an interest in such things) that the French pilots who bought their Rafales to a Red Flag exercise several years back did their level best to avoid doing pretty much anything useful and productive. The reason for this was simple, they were not there to participate in the exercise for training purposes but for ELINT collection purposes. A cheap trick but they got away with it so fair play to them really.

    A lot of the problem for the French was that they didn’t want to risk having a de-briefing observed by certain other participants for marketing purposes so their pilots were instructed not to take any chances during the exercise.

    Essentially they were told to play things safe and let the marketers spin everything after the fact when nobody is around to refute it.

    “Generation” is a marketing term it is meanngless.
    Anybody basing their “argument” on such doesn’t have an argument.

    To quote Morrocco is laughable, it is well documented what happened there.

    As for the UAE, well isn’t it strange they bought Mirage 2000 and then bought F16’s, i wonder if they are keeping all political channels open… :rolleyes:
    (PS got anything to say about the F35, non marketing comment and facts prefered)

    😀

    Right, so when bluewings says you can’t compare an F-16 to a Rafale because the Rafale is a “half generation” ahead… you say nothing. When I point out that the two are of the same generation by any reasonable standard suddenly it is a “marketing term.”

    As for what happened in Morocco, you are right it is no secret. The F-16 won by offering a better plane at a better price to the actual operators while the French tried to push an over-priced political deal with the leadership.

    The Moroccan Air Force got their plane.

    The same thing happened in the UAE. After a long and careful evaluation the UAE Air Force selected the F-16 OVER the Rafale.

    The Mirage 2000-9 was a non-competitive upgrade deal with a few extra airframes tacked on to fill out the force structure.

    Hopsalot :

    The UAE Blk-60s can be compared to their M2000-9s and not to the Rafale wich is half a generation ahead .

    If you want people to take you seriously you need to get the basic facts right.

    Both are 4th generation jets and the F-16 was selected over the Rafale by both the UAE and Morocco.

    The United Arab Emirates’ selection of the F-16 Block 60 (see IDR 6/1998, p27) had been widely expected. However, the announcement of the US$7 billion contract for 80 F-16 Block 60 aircraft ends a period of deep uncertainty at Lockheed Martin Tactical Aircraft Systems (LMTAS) and will profoundly affect the fighter market for the next decade. Losing the UAE order would probably have been the end of the road for the F-16. LMTAS’ order backlog was set to run out in 2001, just as Boeing, Dassault and Eurofighter expect to be starting production of new aircraft. The UAE contract keeps the F-16 line open and funds the development of a very advanced new version, which has beaten the Eurofighter and Rafale in an exhaustive customer evaluation.

    http://articles.janes.com/articles/International-Defence-Review-98/UAE-BOOSTS-F-16-WITH-US-7-BILLION-CONTRACT.html

    Selection of the Block 60 F-16 over the Dassault Rafale and Eurofighter EF2000 after a four-year evaluation was announced on 12 May by Sheikh Khalifa bin Zayed Al Nahyan, deputy supreme commander of the UAE Armed Forces, during a visit to Washington.

    http://www.flightglobal.com/news/articles/uae-block-60-order-provides-edge-for-lockheed-martin-37251/

    Morocco took delivery on Thursday of a first batch of 24 F-16 fighter jets from the United States as part of its air force modernisation programme, a senior US officer said.

    Four F-16s were delivered to Morocco, Major General Margaret Woodward of the US Air Force told reporters in the southern city of Marrakesh.

    Another seven would be delivered at the beginning of 2012 and the remaining 13 in the following months, she added.

    The 24 F-16s, the CD block 50-52 model, were among the most modern versions available, said Woodward.

    The contract with the US, which includes the sale of equipment, services and pilot training, is worth an estimated $2.4 billion (1.7 billion euros).

    The F-16s competed with the Rafale jet produced by France’s Dassault to win the Moroccan deal.

    ouch!

    1/ india:

    long and exhaustive evaluation process: the result is not about what they believed but about what they measured, big difference

    2/ switzerland

    evaluation process that required off the shelf finished aircraft, switched by politicians to a future project of evolution of an aircraft that was measured below reference point in several areas (and finished dead last in pretty much any domain in which the swiss tested it)

    for the rest, the “rumors” are usually quite well documented be it becaus ethe choice was made on political pressure like in korea or because a european country $crewed up big time (morocco) for example…

    Yep, pretty much like I said. You want to dismiss the occasions where the US wins and accept the case where a plane you like wins…

    Well documented rumors? :rolleyes:

    The fact is that the US’s 4th generation planes have won more than they have lost against their European competitors and that says an awful lot about how they perform. The idea that one force after another is selecting jets they believe to be inferior because of outside factors is just wishful thinking on your part.

    but it’s only point .2 Mach slower than a clean Rafale. Load the Rafale up and they’re both similar in top end speed.

    The Rafale in BW’s picture won’t come close to M1.6…

    That is what people always seem to forget. The F-35 suffers in clean comparisons because of the drag penalty associated with carrying everything internally.

    If you go hang pods, bays, CFTs, and everything else on a 4th generation jet all you are doing is trying to do what the F-35 does from the start… inefficiently.

    Cheers .

    You can graft as much stuff as you want to a 4th generation plane, you still have a 4th generation plane.

    Look at the UAE’s F-16s. They are incredible planes, but there is just only so much that can be done with a 4th generation airframe.

    it depends on the way things happened… when you have the aircraft A that wins the selection process, and then politicians take the aircraft B, it doesn’t necessarily mean that the B was better, to say the least…

    when the aircraft A is selected during trials, and the aircraft B isn’t, that pretty much means that A proved better than B.

    In the Indian competition (one of the rare where the rules were made public from the start), the two that obviously outflew the competition were the eurocanards

    That is a very simplistic way of looking at things.

    In India the two aircraft the Indians believed met their requirements were the Rafale and EF. The Indians selected what they believed to be the cheaper of the two.

    The same thing happened in Switzerland. The Swiss believed three aircraft met their requirements, and chose the cheapest, the Gripen.

    Meanwhile Korea, Singapore, Japan, Morocco, and the UAE, selected F-15s, F-16s or F-35s over European competition. Naturally around here all of -those- deals are seen as political. (Or there are -rumors- that one plane or another really “won” even though it wasn’t selected.)

    hopsalot, your nick reflects your way of thinking (believing?)

    LM has been saying that for years now… and still, the new problems keep arising, goals are lowered to be able to pretend that the aircraft reach them (it’s rather that goals reach the poor performance of the aircraft, in fact), but you guys still maintain your claims regardless anything that may happen

    It is development, finding problems is the name of the game. The F-35 has experienced a level of scrutiny few other programs have.

    Every little crack, every comment in a developmental report, etc is blown out of proportion by hysterical critics. In most other programs half of the issues the F-35 has suffered would never have even become public, or if they do it is in the form of rumors.

    The overall trajectory of the program is quite good right now. More work remains to be done but progress is now rapid.

    I believe India answered that question pretty well… New airframe, instability, fly by wire, reduced RCS, built in sensor fusion etc.

    I love how the Indian contract “proves” something while all of the occasions when F-16s or F-15s were selected ahead of the Eurocanards don’t…

    I remember a Gripen Engineer talking about the NG and saying that the only way to make it more stealthly would be internal carriage, although weapon pods could address that problem in the future. 4.5+ aircraft manufacturers aren’t sitting on their hands while the almight JSF is being produced.

    The engineer you were speaking to was lying or clueless, it is that simple.

    The type of LO that is present in the F-22/F-35/J-20, etc can not be retrofitted into a 4th generation jet no matter how much you dress it up.

    You -can- make substantial RCS improvements to an otherwise fairly standard 4th generation jet(SH,EF,Rafale, etc),but no incremental approach is ever going to rival a dedicated 5th generation design.

    Long range stand off munition is another way to offset the lack of all aspect LO.

    There is a place for stand off munitions, but they will never be able to replace manned jets.

    Hum a few navies have and even more are now building stealth frigates. The fact that the US stayed way behind for a while and is planning a doing so in the future with the prologation of current class of ships doesn’t mean the rest of the world is. China, Russia, India, Europe… many countries are building stealth ships.

    It doesn’t speak highly of you that you would wade into a topic you clearly know so little about.

    Consiering your rude and rather unpleasant attitude toward posters who you do not agree with i’m inclined to think that wouldn’t be such a bad thing.

    It is what you are left with when you don’t have facts on your side.

    The simple -fact- is that numerous previous programs have suffered developmental problems only to go on to stellar operational service.

    The F-35 has has issues no doubt, it is a incredibly large and complex program, but it is finally over the hump and well on its way to becoming a system that will be indispensable to commanders and warfighters in the coming years.
