    Given the unofficial indications besides the Luftwaffe and EADS I have gathered, I find it highly undoubtedly that the Typhoon failed during the high altitude tests. But I’m certain we’ll soon know more.

    Just a couple of things :

    Scorpion82 :

    Until you give me a proof , I don ‘t believe it . As I see it , it is an almost impossible task .
    Since it is a towed object , it moves a bit . To “direct” jamming signals towards the target , it would need to be Pesa or Aesa to be able to direct the beam(s) , but it is not such a system .
    There are some jamming techniques DASS can do but not the Ariel .

    Edit:
    The most important parts of the article

    The Ariel is a high-power, fiber-optic linked decoy, integrated with the DASS, rather than being a simple repeater.

    The system uses a techniques generator based on digital-RF-memory (DRFM) components and can produce a full range of noise and deception signals between 4.5 and 18 GHz.

    The signal from the decoy is power-managed to match the signal from the radar and the radar cross-section (RCS) of the target, which changes with aspect angle.

    The Ariel Mk3, in the prototype stage, is an even more powerful decoy with a phased-array beam-steering device, providing full spherical coverage with 1.2 kW of power.

    Might be worth noting that this article is from 2002, given the fact that the TRD was introduced on the Typhoon not earlier than 2005 or possibly even later, it could be the Mk3 or an even more advanced system!

    I thought the USAF F-15C was to integrated onto the centre line hard point?

    To my understanding the pod will be installed under one of the intakes, in other words where the TGP of the F-15E is located. As C/Ds aren’t wired yet this might be one of the reasons why it will take some time to integrate the system, next to the software wise integration. The F-15C’s cockpit and avionics are very different from those of the F-15E and its even newer export variants.

    That’s AA1 . Now the AF1 is flying.

    And what’s the difference between AA1 and AF1 which will magically increase it’s max. Mach? The only difference between those two is the internal structure which results in a few kg being stripped of the aircraft and that’s it.

    Defence Science Journal of DRDO had a LCA special issue , it mentioned the RCS of LCA was 1/3 of Mirage 2000.

    So if we know the RCS of M2K we will have a good idea on RCS of Tejas.

    Some french sources claim that the Rafale’s RCS is 1/10th of that of the Mirage 2000 if this is of any help…

    Cruise radius is defined as the distance to a point a aircraft or a ship need to turn back to make it back, not combat radius.

    Right, but you stated an 800 km combat radius on internal fuel for the Gripen C in post 2. The 800 km combat radius figure for the Gripen was floating around since the A model and is likely to include drop tanks.

    This means
    JAS-39 have a cruising radius of approx. 800km without extra fuel.

    Doesn’t sound like combat radius.

    Do we know what was the range?

    Are those indicators (40 and 80) supposed to represent range, and if so are those in miles or nautical miles?

    Nautical Miles and yes this is the range.

    Regarding the Super Hornet from the Wallace ppt:
    CAP: 380 nm with 2 h loitering (3 x tanks, 4 x AMRAAM, 2 x AIM-9)
    Ship attack: 805 nm/1135 nm (3 x ET, ATFLIR, 1 x AMRAAM, 2 x AIM-9, 2 x AGM-84)
    Maritime Patrol: 300 nm with 2.3 h/3.2 h loitering (same config)

    No idea why there are two values for the ship attack/maritime missions, maybe dependent on wheather 330 G or 480 G tanks are used.

    Nice try but the ‘1000 nm strike mission’, that is ‘radius of action’ which includes the range of the Scalp/Storm Shadow.

    Nice try to invent something to make the competition look worse than it is and your beloved pet toy looking better than it is.

    As there were some talks about using the MiG-29K as a land based fighter, of course it’s possible, but why should anyone buy it, if the MiG-29M/35 is available as a pure land based fighter, without the equipment required for carrier operations?

    Regarding the radar. The Zhuk-AE (with 1088 TRMs) is claimed to offer a detection range up to 200 km against a 3m² target (head on).
    I think the AN/APG-79 may enjoy some advantages as the US is more advanced than the Russians in that area. I wouldn’t overestimate the Americans on one side and the Russians on the other side however.
    There are rough indications but no real numbers which would prove a really superior performance of the -79. And with regards to the modes, already earlier Russian PESA designs like the BARS are capable to engage AA and AG targets simultaneously, why shouldn’t a new AESA radar be able to do so?
    And what proofs do we have with regards to LPI modes in the case of the APG-79 and EA capabilities being operational right now…?

    @Cola
    All aircraft since block 5 are cleared for 9 g, but there are still some older aircraft flying around. The italian Typhoon flown at Zeltweg last year for example was still a block 2 aircraft with 8 g limit.

    Well the Rafale definitely rolls more preciously and if that’s seen as the “can’t be flown like that” then it is true, though not overly important or particularly impressive. The climb after the slow speed pass is definitely nothing special and first and foremost dependent on the TWR and drag.

    Hello Scorpion82 , you say :

    “”And those manoeuvers are which exactly? “”

    You answer your own question by quoting me :
    “”Btw , Cédric Ruet only says that the “Square Dance” can hardly be done with the Typhoon , that the Rafale is the only one to start a straight vertical acceleration from 100 Knt and go looping (thanks the M88s) and is the only fighter to land after a low and hard looping .””

    I know what the Square Dance is , I ‘ve got no less than 3 videos to show what it is and I also have a pdf which explain everything 😉

    To make it short , the Square dance goes like this :
    -start stabilized @ 380 Knt , inverted barrel then hard opposite 90deg turn , acceleration .
    Repeat 4 times to make a square with a end speed of no less than 400 Knt .

    The Typhoon can ‘t , the F-16/F-15/F-18 can ‘t and I am still waiting to see a Russian made aircraft trying it .

    “”The same is true for the loop directly from the high alpha pass.””

    With Le Bourget airport restrictions (as Cpt. C. Ruet said in the video) , only the Rafale could archive “the trick” .
    I only repeat what is said by the Pilot .
    You seem to know what you talk about but myself , I am no pilot . I can only post and translate at this time .

    Cheers .

    Sorry to say so, but that’s nonsense. I’ve seen various aircraft doing square dances and pulling a loop from a high alpha pass, that’s nothing special or specific unique to the Rafale.
