    Yes, MMR -AESA = 70 to 80 Kg i think.
    new EW shall be replaced by old EW. Currently Tejas has the sensors.

    In addition, many more LRUS ars going to loose weight.

    You forgot Slashing of Landing gear weight.

    Aesa radars are heavier than older gen MMRs, which is an issue for most vendors to find the right compromise between the right size of the radar and the added weight. The Mig 35 for example had several different versions of Zhuk AE in different sizes, because the added weight is said to make the fighter unbalanced and they have to teat difervent nose and ra dar sizes.
    EF reportedly have similar issues and we will need to see how the integration turns out for LCA MK1A.

    Agree but they are not that heavier. Min weight is due to cooling system. One Indian company reportedly has make one such nice system. Ballast weight shall be 300 KG while the weight increase of AESA shall not be more than 100 kg. If we can do some aerodynamic improvement and reduce weight, LCA Tejas shall be an all to gather a different aircraft.

    The airframe won't get changes and IAF have to stick with less flight performance than it required initially. HMS and HOBS missiles will counter that to an extend and for basic CAS roles, LCA will be sufficient enough too. That's what's a light class fighter should offer at the end, but the important roles will be done by MKI, Rafale / MMRCAs.

    ok got it.. just reread the link you have given previously..

    MMR + ballast was 210 kg... ( i ve mistaken ballast alone is 210kg)

    it is replaced by

    AESA + EW = 260Kg

    so additional 50kg.

    i am getting confused again, What is ballast weight ?

    i am of the opinion, in order to maintain Center of gravity at certain point, they add/deduct weight towards either of ends

    in MK1 front might have been lighter so they added some ballast weight.
    this ballast with MMR together is 210 kgs.
    we are replacing 210 kg with 260 kg aesa+ew .

    am i right in my understanding ?

    as no new F 404 have been ordered nor F 414 ... which leads to believe that kaveri is the only engine that will be used in all MK1A ++++ MK2 +++

    Mr. Raju meant that nose cone will be 50 kg heavier not the entire aircraft. Some 500 kg will be reduced by redesigning the landing gear. Thus Tejas Mk1a wt will be around 6.1 tonne (6560 kg + 50 kg addition in nose cone - 500 kg reduction in landing gear)

    No he didn't, he didn't even mentioned the nose in the quotes I gave, but specifically said that AESA and EW will add 250Kg and that the net weight increase is 50Kg.

    By the time Mk2 is out (I.e if ever), I personally think it will be by 2030-2035....By that time SAAB will have a better Gripen.

    Comparing the MK2 with any other plane is simply senseless...It doesn't even exist yet, apart from CAD drawings that is.


    Infact I don't think the forces are much confident either, we all know how the AF negotiated out a 1A...


    So If I were to bet....The Mk2... Isn't where my money is going.


    Anyway let's wish them luck to make the 1A first...And lets just NOT talk about the Mk2 at all...

    Few at the moment is what I am afraid of..
    These are enough to do proto stage.,
    I am more than worried if these are taken in AMCA rather than Mk2 Lca .

    I hope Kaveri is fitted into Mk1A , mk2 and AMCA as well.

    Kaveri Engine doesn't have the thrust to feed Mk2 or AMCA. Karveri engine is going to be used in UCAV.

    With the current time line and if another MMRCA comes in alongside LCA MK1A, I have some doubts about MK2 as well. It might be pushed further back and come as an upgrade for the MK1A's only
