    Conscript armies are actually the best type of defensive army. Put very simply you want your entire population to know that a Grad and a 122mm ammo store are not the same thing even if a Grad rocket does have a calibre of 122mm. For foreign wars of conquest, or maintaining a global empire then a professional army is much more useful which is why the west prefers such an arrangement. Those countries that had real defensive policies like Finland and Sweden continue with conscription…

    We all witnessed how well a russian conscript army faired when waging war against Chechenia. Didn’t they come back home with their tail between their legs? Didn’t they have to resort to large scale ethnic cleansing to win?

    Ho wait ! Chechenia was not a small nation, Chechenia war was not an imperialistic war and Russia is not a global empire 😀 :rolleyes:

    I agree the authors made a factual mistake there, but the point is that the M-88 too took over 15 years and $1.68 billion to develop.

    Despite that, the Tejas has remained within the sanctioned amount of just $1.2 billion as compared to $6 billion for the Rafale effort. Also, the timespan for Tejas i.e. 20 years is not much more than 18 years for Rafale.

    What the point comparing the prices of the Rafale/M88 to that of the Tejas/LCA. Are you aware of the difference in the cost of life between India and Europe? For a fair comparison you should probably multiply the indian price by 10 or 20 …

    And comparing the Tejas, an aircraft bairly in the M2000 category, to the twin engined Rafale is a bit of a stretch …

    And also, maybe it took 12-15 years to develop M88 but in the end you have an engine which is up to spec and delivering the performances asked by the customer while the Kaveri and Tejas failed to reach their contractual performances. It may take something like 10 more years to do so … so if you want to compare the development time of the Tejas to that of the Rafale wait this development is finished. Rafale has been in service for 10 years now, has seen many international exercises and has both a naval and land based version, not even speaking of the much larger capabilities (nuclear strike, reco, antiship …) which limit the very relevance of the comparison.

    I agree with this view completely. F-16, F-18 and Rafale etc. have 7000-9000 max. payload capacity of which only 2000-3000 kgs is utilized in normal fighter configurations. The facility of such high loads is probably to deliver nuclear warheads, or very heavy cruise missiles only.

    As a fighter in a normal profile, an F-16 or Rafale may NOT provide any advantage, tactical or otherwise over the Tejas.

    Cough cough,
    sorry but if 2 engines, IRST, LWS, MAWS, larger and more capable radar, datalink, more fuel, 6-8 missiles, supercruise :D, up to 2-3x2000l drop tanks and being on specs do not provide any advantage, then buy Mig21s

    And nuclear bombs or heavy cruise missile are not he only load that justify a 9000kg max payload. You reach it pretty easily with 3 2000l droptanks, 6x250kg bombs, 6 AA missiles, max internal fuel which would be a normal far CAS configuration.

    Nice pictures, thanks.

    that’s the first time I see a Raptor with drop tanks.
    The argument that drop tanks would ruin any stealth feature of the eurocanards has been widely used here to belittle their capacities. What about the Raptor? Is it still a stealth plane in that configuration? Why not designing stealthy droptanks?

    I think the relationship betewwn range and RCS is a power of 4 so to decrease the range by ten you have to decrease the RCS by 10,000.

    I find very funny that the Sukhoi fanboys are ready to accept that the Su 35 has a signifcantly reduced RCS, such as 1m2 wahouh :-/, while denying this to the Eurocanards which were designed with features such as S shaped antenna from the onset.

    My source is an old issue of Air & Cosmos stating that Spectra was the first sytem to generate a significant number of MMIC in Europe.

    That doesn’t prove that active cancellation is possible or even used on Rafale. I can still separate speculation from reality.

    The fact you must be able to compute your own signature is something that make me think that active cancellation is not the wonder, all around stealth technique some people would like to see but a bit more limited in its scope.
    I long ago hypothesised that active cancellation would be used to eliminate radar returns from a few hot spots on the airframe, not to cvancel the whole aircraft signature. Aiframe shaping would not need to be as radical as on F117, F22 or F35 if you could concentrate the radar return on a few hot spots and reduce these returns with an active cancellation technique. The air intakes spring immediately to mind since S shaped intakes would not totally eliminate radar returns from the fan blades but reduce it, and could be designed to concentrate the signal in a specific direction. It would also be easy to dispose antenna in the air intake to monitor this return and measure its parameters (frequency, pulse shape, phase, repetition, intensity …). Active cancellation could then be used to eliminate this return using combination of DRFM and beam forming AESA antenna. One can note that Rafale has S shaped intakes and Spectra has 2 AESA ECM antenna just upfront of the air intakes.

    Wow thanks for the comprehensive answer, the ‘lure’ part of what was said to you is (to myself anyway) very interesting, perhaps the radar painting the Rafale is lead to believe that its picked up a another type of aircraft – a big dumb transport for example or could it be it spoofs the radar to think the target is futher away then it is in reality, the jet then goes flat out at the rafale only to find the Rafale is actually already close enough to get a good shot and the first warning he gets is his RWR telling him a missile is on its way to greet him, Of course though im probably all wrong but hey it sounds cool.

    The “lure and jam” part probably referred to the ability of doing deception jamming and noise jamming at the same time. Deception jamming is a feature of any modern ECM system anyway. I don’t know the advantage of doing both deception and noise jamming on the same target? Maybe the noise (barrage, saturation) would degrade the radar performances enough so it becomes unable to detect the more subtle deception signal?

    That was only speculation. It has never been officially announced by any representative of Dassault, Thales or the french government. A thales representative started the whole affair by suggesting there were other techniques than fuselage shaping and RAM to design a atealthy aircraft. Then it was probably blown out of proportion in the specialized press. However, it is known that the french directorate for armement (DGA) worked on active cancellation and plasma stealth (like every other such agency). Is any of these techniques mature enough to be used on Rafale?

    I thought the 2 engines were a definitive requirement for the Swiss AF.
    The inclusion of the Gripen in the list seems to show the contrary.
    But could it still be a strong advantage for the other contenders?

    Porn is a somewhat neutral phrase indicating purely a visual object/image for some form of gratification. Jerking off on the other hand refers to an action and is somewhat different. The usage of the word porn in this context is actually rather suitable, it could describe both how forumers here may see it, after all we all love watching planes and warships…….especially if they have Soviet heritage and global ambitions. It could also refer to how this intended to be viewed in Russia as a demonstration of renewed power prior to upcoming elections.

    I thought porn was before upcoming erection 😀 :p

    Do you know if the F1 had an operational datalink with any operator of the aircraft?
