IN can't create industry, they are involved in naval design, but that's it. The fact that we have so many shipyards, or that L&T or Pipavav are more committed to own R&D, than any privat player in the aviation sector so far, has nothing to do with the forces.
HAL is not IAF owned, but by the government and the same is the case for ADA and NAL, which is everything India has in the aviation industry and which are dependent on each other. That's the key difference to the Indian naval industry. More players, more know how and experience.
Which proves, that even if the navy would be more committed than IAF, the problem is the limited industry!
That's why the LCA and MKI and MMRCA/SE MMRCA programms are so important for the nation, to build up the Indian aviation industry, in a much broader and capable way, than what we even have today.
What has IAF to do with the development failure of kaveri? With the performance issues of DRDOs radar, Astra or Sudharshan?
Development failures, mistakes or delays are based on the developing agency, not the customer!
The difference is years if delays! You can't honestly think that IAF in 2017 can accept technical capabilities that were agreed on in the 90s and was suppose to be delivered years ago. These delays are caused by development problems, not high requirements, just as IAF asks for modernisations, because of development delays.
No doubt about that, but most of what you pointed to, has nothing to do with Tejas development, so has no relevance here.
Of course because the priority is not on the sub systems they should develop, but on the main projects, LCA / FGFA / AMCA.
If DRDO delivers, great, but don't make the fighter programmes dependent on DRDO promises and simply use the access to techs and systems we have!
You are mixing things up here, with the issues of ADA and you can't defend blame that is well deserved. There is a reason why DRDO gets blamed by everyone, because they are not delivering to their great promises! So it's on them to change things, to not get blamed and not on us, to simply be silent.
Here again you don't understand that DRDO is not important for AMCA, they can't contribute anything important to the programme, without getting foreign help on their own (Israeli help for radar, French help for engine, maybe Swedish for EW). Important are the designers, developers and the production agency (ADA, HAL or private players), while anything else can be sourced from abroad if necessary.
So leave DRDO out and let them develop sub components independently, if they deliver great, if not the fighter programme is not at risk.
