    In 3 days and 10 days is what we heard more than a month back. It seems Tejas is endangered by HAL's inability to deliver more than any Videshi SE fighter.

    Guess What......
    Kaveri is 341 cm long where as GE 404 & 414 both are 391 CM long.....
    By using Kaveri we get equivalent of 0.42 plug in by default..... :bounce:

    Don't count your chickens yet. What if Kaveri ultimately meets the requirements and in doing so, increases in size/length? :)

    Well GE 404 & 414 both being exact 391... gives hope that Kaveri can be improved without any change in length,
    As I have said before... amazing things can happen if we get Safaranized Kaveri working, in fact most of LCA decisions are help of awaiting outcome...
    Lets hope for the best

    NLCA has LEVCONS as a feature over AF LCA, the LEVCONS are meant to give NLCA more control at carrier landings and at lower speed, . And specially, this shift in CG help it in maintaining the angle if approach while carrier landings. Anyways, ASAIK NLCA has the most aerodynamic design between all three (LCA-AF, NLCA , LCA-Trainer).

    Those who have confusion in NLCA , should watch this video.


    Not really, they are waiting for FOC and amazing things will happen if LCA achieved its FOC.

    Lets not confuse between IOC and FOC versions, true capability is what IAF has drawn for it, That should be considered ..

    Just one single question I want you to answer,

    Just after mere 6 test flights, The first Gripen fighter went into serial production jigs.

    Of these six test flights, one ended in a crash.

    Also the second production gripen version crashed again.


    You want me to believe that ADA is incapable of adding WVR, EW, BVR, gun to the first 20 IOC tejas mk1s,

    While SAAB managed all for gripen even after two crashes??

    Comparing jag to tejas is height of ignorance.

    Let's compare the STR, ITR of Tejas & jag to know that this comparison is a joke.

    All IAF Tejas mk1s(whether IOC 1 or IOC2, or FOC) will be qualified in future to fly with multi ejector racks that can accommodate LGBs, WVR missikes,EW, litening pods, BVR missiles ,

    all in a single sortie
    as a true multi role fighter.

    Making mid board pylons wet & getting multi ejector racks that can accommodate LGBs, BVR missiles in one pylon is no rocket science for people who mated brahmos with su 30 mki.
    The first 20 tejas mk 1 ,IOC fighters will all be retrofitted with these capabilities, because these involve no deep airframe structural changes.
    Comparing tejas with jaguar just shows the ignorance of the person doing it.

    When you are worthless, you become Theoretically worthy by getting certification. As I said, just because certification hasn't been done doesn't prove anything.

    The side weapons can be Astra BVR. Unnecessarily Branding a BVR as WVR to satisfy your ego ruins the mood. Only those who are mentally unsound use WVR-exclusive missiles. Medium ranged AAM like Astra can also act as WVR. Do you know of any WVR used by USA? Why do you think they don't need it?

    Its like using a sniper instead of a simple gun.. which makes its costlier and incapable. Generally BVR have Inertial and Radar guidance whereas WVR have IIR.

    No additional hints required....
    Have you heard about AIM-9 Sidewinder.....

    Ok, WVR may be required in addition to BVR. But, he was unnecessarily stating that there is no place to hold BVR. He wanted to create an impression that Tejas can't carry BVR. So, I lashed out against him.

    Expecting to carry 4 AAM missiles - 2WVR and 2BVR in 4 hardpoint and still delivering payload is a bit excessive

    If anyone has questions regarding payload of Tejas in different roles under its specified combat radius ..

    Refer to this chat which is official, Its old but relevant ..

    When your are heading for battlefield support, there is no need to have BVR on-board..
    Do not mix the roles...

    I think, he said that such configuration is feasible,

    If you read the chart then you can notice, Air-superiority role has :

    2 x BVR
    2 x WVR
    2 x drop tanks
    1 x air2ground munition ( Which is missing here at mock up )

    Here is a mock up of Tejas at AERO INDIA ..

    What you believe is up to you, but it's the facts that matters!
    The gun was tested on the ground as far as I know, we already saw reports about integration problems of Python V, Derby integration just started..., while the production and delivery of the first 20 is already going on. So the issue is not if they get these capabilities at a certain point, but that they don't have it now.

    Comparing the strike config of a multi role fighter, to the one of a strike fighter is wrong, but praising the turn rates of LCA compared to the same strike makes sense?

    If you would look at it more realistically, you would understand, that being able to offer the same strike load as the Jag is actually an achievement for the LCA programme and even is good for IAF to increase the numbers of fighters for CAS missions, in areas where air superiority is achieved.
    The problem however is, that LCAs prime role is air defence and so far it lacks all the necessary capabilities to do the job until FOC was achieved.

    The concept of strike fighter jet itself is bad. If the fighter jet doesn't even survive till the payload is delivered, what is the point? If air superiority is already achieved, why not use Boeing 747 modified to carry hundreds of heavy payload? Do you call such jets as fighter jets?

    One does not carry 2 LGB for battlefield support, if I am right. We would replace that with probably 4 BVR in rack of 2 each instead of LGB.

    True, I think any single role fighter is outdated and doesn't fit to modern air warfare anymore, unless you fight Taliban or IS. India doesn't have such a luxury and therfore we need capable multi role fighters.

    That's possible, as we can see at Chinese fighters for example. The downside is that it might increase weight and drag, which is already an issue for LCA.

    Yes sir, amazing things will happen to Tejas MK 1 once FOC is achieved...
    I am talking about direction Tejas MK 1A & Mk II will take once Safran Delivers on it's part of deal.

    In a fighter plane center of gravity keeps shifting within a defined limit all the time,

    Due to depletion of fuel, weapon release, etc.


    In a cutting edge Relaxed Static Stability 4 channel ,all digital fly by wire software operated flight control system like tejas,

    The flight computer receives data relating to CG shifts from sensors,

    & Operated actuators , to move the control surfaces .

    This results in correction of the combined lift forves to counter the CG shift & to keep the plane flying level.
    The above scenario is managed by altering fly by wire software for dynamic shifts in CG , during flight.


    The same process is followed for a plug in that is permanent shift in CG ,

    With alterations to fly by wire software & validation by test flights.
