you sound quite stupid here, just like those ch*tiya IAF-wallah's.
Its not DRDO who is "writing" over-ambitious unrealistic
He is actually on the spot! Ambitious is DRDOs and ADAs most favourite term, the problem is, they have no clue what realistic means, that's why LCA faces these delayes and why they celebrate any babystep in the media and try to fool the public. IAF did not messed up Kaveri or MMR development, they didn't planned to do anything on their own, they didn't jumped into things that were completely out of their capabilities. But the problem in this topic is, that they are doing the same mistakes with AMCA again and that's what's the really stupid thing, because it proves that they didn't learned anything out of their mistakes!
to jump from 2nd gen tech to 4th gen tech is no easy a job
That's the point! It was out of their realistic capabilities, therefor they should have never started to do the important developments alone, but their indigenous pride blinded them and that's why they are critizised by some, while the major part of the public still ignors the facts and why the jump from not even 4th gen to 5th or even 5+ gen like they now claim will be waaay too big again!
& add to that consistent changes in the requirements of the IAF...& sanctions by US post-1998.
Which are just silly excuses, nothing else! IAF wanted a new engine, when it was clear that Kaveri was waaaay too heavy and underpowered to be used (DRDOs failure), they wanted ELTA to join in radar developments when we didn't get it ready (DRDOs failure), they wanted EADS to help on weight and drag issues (ADAs failure). Wrt to sanctions, who told DRDO to go for US techs for LCA although they were Pakistans ally, while we easily could have got save Russian, French and to some extend even Israeli techs? Definitely not IAF and even today they went with USN and initially prefered LM and Boeing to navalise LCA, instead of Mikoyan (Mig 29K) or Dassault (Rafale).
Currently it is even IAF that prefers the indigenous further development of Kaveri engine, while DRDO itself prefers the JV with the French, so how do you really want to blame IAF for beeing responsible or not supporting indigenous developments???
i am of the opinion that HAL & ADA have gained tremendous experience by the development of LCA tejas
Then you are highly mistaken! As I pointed out, they are doing the same mistakes again and making promises they can't hold. LCA does not give them any experience in stealth design, only in useful materials. The important engine and radar developments, that could have been furter developed to be used in AMCA were failures, so either they start at the begining again, or find co-development partners, like they should have done it in LCA as well. To understand what DRDO and ADA learned from LCA, you just need to look at their participation in FGFA. Cockpit layout, use of composite materials, some avionics, minor re-design. All important parts are on their side, because we can't do it today and that's the reality you and some others has to accept. We made major mistakes in the LCA program and that's why things get that bad in an otherwise very good development!
Anybody want to hear my stealth criticisms of the pictured AMCA shown in post #1?
No! Please spare us with your biased and completely false comments, you have started enough blame games, based on nothing.
