    Are you really requesting a source for Claim No: 1? Everyone knows this, it’s been widely reported since January ’12. Very easy to find via a Google search.

    You’ve started something now, Hopsalot. A certain Troll Princess will be fuming to have been banned right now.

    :dev2:

    Bah, started something maybe but I am about done with it.

    Of all of the fan clubs on the internet the Rafale’s supporters are the least reasonable. You don’t see the Eurofighter supporters claiming that it is the best at everything under all circumstances and that it won every technical evaluation it has ever entered… you don’t see the F-15E supporters insisting that it is the best dog fighter ever, etc.

    Somehow with the Rafale reality doesn’t apply.

    A guy claims, inaccurately, that an aircraft doesn’t have an IRST, you supply them with a source stating it does… and they ignore it. They claim the Rafale never competed in the UAE, you provide them a source… and then they just insist the competition doesn’t count. You provide a source directly from a Rafale pilot… and they complain that his name wasn’t provided. (yet they will of course believe internet rumors about exercise results or the supposed victory of the Rafale in technical evaluations in competitions it lost…)

    You state a common knowledge fact about the Indian competition… suddenly it is “sources please.”

    Whether the “debate” continued a day or a year nothing would change.

    1. Please sources…
    2. Please sources …
    When competitors aren’t available for a fly off – the tech . eval. is not for real – only paper BS.
    3. Wrong IFTS is not Internal IRST, but Internal FLIR and Targeting System. See manufacturer sources – not a word about IRST…

    4. Rafale underpowered compared to F-16 blk 60…
    Rafale pilot (unknown ?) speculate why UAE want more powerfull engine – he didn’t flow blk 60 so no comparsion …maybe they want a leap forward in performance compared to f-16e – so 9t rafale engine will be a solution…
    We don’t now pilot’s name… ( invalid sources)
    Rafale can supercruise while blk 60 not, Rafale B/C has better T/W ratio than F-16E/F…
    I think Rafale was underpowered in comparsion with EF-2000 (another UAE candidate)

    This is really getting beyond stupid.

    I have already provided you ample sources for each of my assertions, now you are resorting to the usual weaseling and refusal to accept any information you don’t like.

    The fact is that the Rafale has lost more often than it has won when it has competed against other 4th generation aircraft. Its only win to date has not resulted in a contract even after two years…

    The Rafale is an excellent aircraft, but dealing with its less rational fans on the internet gets tiresome. Some have problems understanding that relative to other advanced 4th generation fighters the Rafale is nothing all that special. It has areas of strength and areas of weakness. It is a good all around performer with some nice features… but all of the 4.5 generation fighters have some nice features.

    1. The first part of MMRCA was technical evaluation – each contenders did a real a-a, a-g missions, there was radar and weapon system test ( MiG-35 for examle fire real R-77 with AESA radar support).
    The tests was conducted by IAF in the similar way as Swiss technicall evaluation, and only Rafale and Eurofighter pass the tests.

    No, only the Eurofighter and Rafale were assessed as meeting the Indian requirements, and the Rafale was selected as the cheaper aircraft of the two.

    3. F-15/16 didn’t beat Rafale in any technical evaluation.

    UAE- there wasn’t any technical evaluation at that time.
    Morroco- there wasn’t any technical evaluation at all.
    Korea- Rafale win tech. eval. according some sources.
    Singapore- Rafale win tech. eval. according some sources.
    Quatar- some sources says Rafale was better then SH and F-15 during tech. eval.

    Absolutely untrue. In all of these cases there were technical evaluations. Not all evaluations require a fly off. Most competitions do a detailed analysis of the specs and clarify grey areas through rounds of follow up questions. This is particularly true in cases like the UAE deal where the competitors weren’t available for a fly off because they were either unfinished (Rafale) or were a new variant that had not yet been flown. (F-16 block 60) That does not mean there was no technical evaluation. (In the most recent Korean competition the Koreans flew the F-15 and Eurofighter, but were unable to fly the F-35 and instead accepted a flight in a chase aircraft. Nonetheless the F-35 won the technical evaluation with the F-15 finishing in second.)

    Additionally, there are frequently rumors of one losing aircraft or another having “won” the technical evaluation. It is all too easy to “leak” this sort of information to a gullible defense reporter or blogger giving a manufacturer some cover after the fact. Unless substantiated as in the case of the Swiss competition these rumors are just that, rumors. (there are of course rumors that the Typhoon “won” the Indian technical eval before losing due to its higher costs…. “Many rumours circulated at the time and the word on the street was that the Eurofighter Typhoon had won the technical evaluation.” http://ktwop.wordpress.com/2011/01/04/no-surprise-secret-technical-evaluation-in-indian-mmrca-deal-found-on-the-street/

    4.F-16E/F is nowhere near the Rafale …
    -has only FLIR, no IRST fucction

    “The Block 60 F-16, also known as the Desert Falcon, was developed specifically for the UAE, which received 80 of the jets between 2005 and 2010. It features more powerful GE F110 engines, a Northrop Grumman APG-80 AESA radar, conformal fuel tanks, integrated infrared search and track (IRST) system and advanced electronic warfare system.”

    http://www.flightglobal.com/news/articles/flight-test-lockheed-martin-f-16ef-block-60-bridging-the-gap-174510/
    -bigger RCS and IR signature
    -worse performance (no supercruise)

    … and yet the UAE preferred them to the Rafale. 😎

    Part of the reason is that the UAE considers the Rafale too sluggish when compared to their F-16 Block 60s:

    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.

    well, over 600 requirements which put together don’tg leave much room for something else…

    Of course they do. Requirements are just that, requirements. They are not a measurement of which jet is more “advanced” or anything similar. There are requirements a Harrier can meet but that a Rafale can not, which is more advanced? Similarly there are requirements that an F-111 could meet, but a Rafale could not… so forth.

    er, no, the swiss evaluation (tests and so on) evaluated the aircraft, and even the “evolved version of the gripen ” scored poorly compared to the other two contenders… it’s t a decision by a politician (Ueli Maurer) that had put the gripen as a most adequate choice… nothing to do with an “evaluation”

    It had everything to do with the evaluation. The Gripen NG was viewed as sufficient for Switzerland’s needs and was the cheapest option available.

    what UAE orders? the Rafale was nowhere near when UAE bought the F-16s. Morocco wasn’t “lost to the F-16”, it was messed by the French all aloe without any competition.

    Come on man… do some reading. The Rafale was pushed aggressively for that deal and was ultimately the runner up.

    http://www.flightglobal.com/news/articles/f-16-and-rafale-in-dog-fight-for-uae-strike-force-order-2742/

    Similarly, the F-16 was most certainly competition for the Rafale in Morocco, it won after all. Certainly the Rafale had some substantial political advantages over the F-16, but not enough to overcome the F-16’s cost and performance advantages.

    you said F-35 would win easily… well, for now, it still has only promises, nothing else

    In a loaded configuration, absolutely.

    the advantage of the 4th gen jet is, as said previously, the capability to adapt its aerodynamics to the necessities of a mission… something the 5th gen jet can’t do

    You could call it adaptability, but it is also true that a 4th generation jet is at its best clean, which isn’t particularly useful, while a 5th generation jet is at its best loaded.

    F-35 is not shaped the way it is to be less draggy, nor are CFT considered for that purpose. Stealth is the main reason . Unless revolutionary aerodynamic properties have been discovered while stealth shaping , it does not make things magically less draggy. F-35 is likely to experience similar drag, if not more, than a loaded 4th generation . Granted loads’ induced drag and their interferences are significantly less than ideal to deal with compared to those of a single body , but then on the other hand, their cross sections combined to tat of the naked jet is less than such body permit.

    Yes, the F-35 has a large internal volume primarily for stealth related reasons, but there are still substantial aerodynamic advantages to such an approach, at least when comparing loaded aircraft. The F-35 most certainly has lower drag when compared against a 4th generation aircraft carrying a similar load to what the F-35 can carry internally.

    Another ill speculation.
    1.Rafale is more advanced than most 4/4+ jet (Rafale proved to be superior than SH and F-16E/F during Indian technical evaluation, and better than EF and Gripen during Swiss evaluation – so we have real performance vs LM paper BS up to now).

    :rolleyes:

    What the Indian evaluation showed was that they considered only the Rafale and Eurofighter to have met their requirements, and of those they believed the Rafale to be cheaper.

    The Swiss evaluation did score the Rafale the highest, but considered the Gripen NG adequate and cheaper and so selected the Gripen NG.

    Of course you seem to have forgotten the “real performance vs Rafale/Eurofighter BS” that was demonstrated when the F-16 beat the Rafale for the UAE and Morocco orders, or when the F-15 beat the Rafale and Eurofighter for the Korean (FX-1) and Singaporean orders. Naturally those don’t count… :stupid:

    2.If you want to go into the future speculation – I can tell you that Rafale shouldn’t be at least easy target for F-35 and any other 5th gen fighter.
    With future advanced sensors and weapons including:
    – FSO IT (TV) and new FSO IR
    – RBE-2 AESA
    – SPECTRA with GaN AESA open new EW capability
    – Link-16
    – MBDA Meteor
    – MICA NG IR/EM
    – HMD
    Rafale will be able to fight BVR/WVR combat with most modern threat.

    Who said anything about easy target? … and what is with the feature list? If you compare the same list to the F-16 Block 60 that was flying 10 years ago you will see…

    -IRST
    -AESA
    -Falcon Edge EW system
    -Link-16
    -no Meteor (not operational anyway)
    -AMRAAM/AIM-9x
    -HMD

    So what is your point? That the Rafale is now more or less where the F-16 Block 60 was a decade ago?

    3. I don’t want to criticize F-35 too much, but it becames frustrating when some guys here try to prove f-35 superiority over other jet in almost every threads in this forum.

    I said nothing of the sort. I made it quite clear that the approach the F-35 took has strengths and weaknesses. Internal storage is the way of the future due to stealth requirements, and it does have some aerodynamic advantages, but it also has disadvantages. A 5th generation jet will most certainly have the edge over a 4th generation jet flying with weapons pods because that is something the 5th generation jet was designed to do from the start.

    Well certainly the CFTs on the Typhoon are there to enable effective Stormshadow carriage for example.

    Not sure that the French seem that bothered about CFTs on their Rafales so this is an export friendly idea isn’t it?

    It all depends on the user’s needs. There are CFTs for F-16s available for instance but most users don’t use them. (including the USAF)

    Weapons pods will of course compromise the aircraft’s performance but I’m sure they will argue that their Rafale is still more spritely and packs a bigger punch than an all internal F35B for example.

    It all depends on the load out. An aircraft with a large internal fuel load and internal bays pays a penalty when compared to a clean or very lightly loaded 4th generation jet, but if you compare a Rafale with tanks, bombs, and pods carried externally to an F-35 with an internal load then the F-35 will win easily. Obviously during the course of a mission a 4th generation jet can expect to drop some of it external ordnance/fuel but can be expected to retain things like targeting pods, pylons, CFTs, and at least some missiles.

    I suspect that if the Rafale receives weapons pods they will be retained except in emergency situations, if they are jettisonable at all. This means that the Rafale would be trading aerodynamic performance for stealth, which may make good sense, but the penalty a Rafale (or Super Hornet) would pay to carry a stealthy pod is greater than that of the F-35, which was designed to carry loads internally from the start.

    As for the CFTs, we don’t know. I vaguely remember having read that CFTs on Super Hornet resulted in slightly decreased drag.
    As for the weapon pods, it all depends on how often do you need to operate the aircraft with full combat load. Contrary to F-35, the Rafale at least can jettison them whenever need arises.

    The CFTs on the Super Hornet and F-16 are essentially drag neutral at cruise conditions, but they are not drag neutral at supersonic speeds. CFTs are not jettisonable so you do pay a price in high speed performance by using them.

    I suspect stealthy weapons pods would not be jettisonable either, not that you would particularly want to jettison the pod that is carrying your weapons…

    as of today, they already give a pretty good performance… add 20% thrust (already possible with the 9t engines in the works, if you can manage to bring more air to them – which is why new intakes are being talked about)… as the C version weighs somewhere around 9tons (slightly more), that would mean a T/W ratio of almost 2 for the empty aircraft, and above 1 even when fully loaded for A2A today, no other aircraft can show such numbers

    I was referring to the concept art of the Rafale with the conformal fuel tanks and multiple weapons pods. That is going to add a significant amount of weight, and drag, particularly at transonic and supersonic speeds.

    It may still make sense of course, but I suspect that the Rafale pictured, even with uprated engines, would be less than awe inspiring from a speed and acceleration standpoint.

    We are talking about the basic F-22A in its present form, though. Now imagine the design would be evolved into strike-optimized F-22B (for one tenth of the development cost of the F-35) – what exactly the F-22B could not do compared to what the F-35A will be able to in 2020 and beyond?

    There were extensive studies done on a possible FB-22 that would have included larger bays and much more fuel. It would have traded maneuverability for payload and range. (while retaining speed)

    http://www.fas.org/man/crs/RS21848.pdf

    Such an aircraft would have been pretty awesome, but it would not have been cheap. The F-35A is already cheaper than the F-22 on a unit cost basis and will be far cheaper from an operating cost standpoint.

    … so the F-22 was a mistake?

    The US has the luxury of maintaining a fleet of several hundred aircraft specializing purely in air to air. (counting some F-15Cs) Very few forces have funding for something like that.

    Fredaykin & FBW. I dont think anyone is saying stealth is completely useless. But going by historical data we find that stealth alone offers very little advantage when it comes to survivability. Nobody is disputing the fact that a lower RCS object can get closer to a target undetected, or that it can be useful.

    There is no such “historical” data… in fact the reverse is true. Again, scroll up to look at the UCAVs if you aren’t sure how the professional world views the value of “stealth alone.”

    The only issue is that some individuals over estimate the usefulness of stealth to an almost perverse level. The F35 is very well designed for it’s specific purpose, being part of a US strike package and work as a missile hauler for A2A. Ie it is an offensive system, primarily designed for strike missions. For the AA fighting in contested air space they have the F22.

    This is not true. The F-35 is a strike fighter, but it is designed to be a multi-role platform capable of undertaking the full range of missions assigned to current 4th generation fighters.

    The reason the F35 is debated at all is because most airforces are expected to work in a defensive environment where the enemy is likely to have superiority in numbers (ie a red invasion from the east). To counter this one needs extra everything, stealth is just one attribute out of many. Kinematics, maintainability and useful payload are all just as important and the key is balance rather than over optimising a single attribute.

    NATO has a vast advantage both quantitatively and qualitatively over any “red” invasion from the east. Stealth -is- just one attribute of many, which is why the F-35 is also a 9G capable airframe with an amazing suite of avionics and that will receive the best weapons available in the West.

    One has to remember that in Europe, the Germans could easily have gone the stealth fighter way back in the early 80s… but they chose a highly agile path in the Eurofighter instead.
    [ATTACH=CONFIG]223180[/ATTACH]
    Above is the MBB Lampyridae, the option to go for the BVR superiority machine was on the table but rejected in favor of a balanced approach. Going the extra mile for improved stealth has always been on the table but it has until now been rejected. The compromises havent been worth it.

    The F-35 is a balanced approach… it is just representative of where the balance existed a generation later than when the Eurofighter was designed. The Eurofighter, Rafale, and Super Hornet all received some RCS reduction but not nearly to the extent of that in 5th generation aircraft.

    EDIT: And thats where the actual debate is. One side questions if the compromises are worth it, while the others either treat stealth as a revolution or ignores the penalties it has on other parameters. IMHO the F22 is the only fighter with no compromises, but that was so expensive that the US only can afford some 185 of them. And that is what happens when compromises arent accepted.

    There aren’t really two “sides” except on message boards.

    In the professional world forces buying or developing new fighters are almost without exception placing a great emphasis on stealth. Already the F-35 has won both of its head to head competitions with the Eurofighter (Japan and Korea) and has been selected by numerous others who could certainly have procured the Eurofighter if they had wanted it.

    When a first-rate technological power launches development of a new fighter and announces that stealth isn’t important to them… and proceeds to advance this non-stealthy design to an operational status, then we can talk about there being two “sides.”

    Right now the only sides are older aircraft and newer aircraft. The newer ones are 5th generation fighters built with a major emphasis on stealth.

    Rarely do I feel the need to chime in on this forum, but there seems to be a fundamental misunderstanding of what low observable, i.e. “stealth” brings to the table. It is not a fashionable trend, nor a gimmick. Air combat tactics have always stressed the idea that the advantage lies with the shooter who enters the fight unobserved. The very earliest of tactics involved attacking from above, or out of the sun when the mark I eyeball was the key sensor of a fighter. Later, with the advent of early radar, tactics involved high speed, then the exploiting doppler shift. Low observable aircraft are not “just” radar signature, it is designing an aircraft that does not emit, and can use passive means to communicate with each other, locate targets, and gather a tactical picture of the battlefield. The f-35 combines these characteristics to a greater degree than any other aircraft currently fielded. Yes, the F-22 may have better kinematics, and a lower radar signature, and the t-50 appears to be a aerodynamic exemplar. The question is to what extent does this really matter in a tactical sense. Those nations who are buying into the F-35 are buying into the idea that fights of the future will be based on superior C3, not two aircraft facing off like a JOUST ( pun intended).

    This could be the post of the day…
