As per the latest report there are dead weights added.. and more layers of secured structure too (though too late, they have realized at the end because they are not sure about the Carbon composite performance on long term and it turned out to be tooooooo good than they have originally anticipated it).. In this case the MK-2 will be a blessing in disguise and i am expecting the empty weight to go down further which as mentioned in new ADA specs ... as of 414 it was because of Navy i am pretty sure about it as they need more oil and power to push it, but yes it has turned out to be IAF's pet too and they have shelved some of there own funds for the same ... which is a pretty good step..
Empty weight will go down by 400 to 500 KG as a result of structural optimization. Wave drag will reduced in MK2 design substantially. Mk2 will be a 5.7 to 6.0 ton aircraft and will carry almost same weight of empty aircraft. MK2 will be a 9G and (11g Emergency) aircraft. It remains to be seen whether they uses lavcon design or aero delta wing. In my opinion Mk2 Navy should be build first so that we may incorporate good thing of NAVAL LCA design in Mk2. Over all Mk2 is going to be an awesome 4.5 gen aircraft with very high T/W ratio in Excess of 1.30. We may expect Eurofighter like performance. It will save a huge amount of money as india should be able to use it in 80% of the missions for which MKIs are required today. We shall be able to incorporate many features of FAGFA in Mk2.
Yet Mk2 will not be an optimum design since it is derived from MK1 and we need Mk2 immideately. This impose a constrain on our R & D. We should immediately start working on MK3 or stealth LCA. It will have an excellent design and shall be a replecement of MKIs except in very long range strike role. We must invest more in R & D. We shall get many-fold return for that. What we need is a vision in political leadership.
