Does it mean can we make a better seeker or a better missile (e.g. improve our AA missile): NO
YES! Because we are involved in the development itself, have access to all techs and gain from experience too, not to mention that we include our requirements in the development stage itself, while the Denel gun was developed for their requirements and we have to take the performance we can get, not the one we might want.
So for any further development or modification of the howitzer, we remain dependent on Denel, while we can modify Barak 8 if we feel the need too. Just as the access to techs and experience will make us more capable to develop a future SAM on our own, while the basic production know how, which in most cases includes only assembly of parts produced abroad, won't help us in future developments.
Looking at the Brahmos example and requirements of India itself I doubt that is happening anytime soon.
It already happend several times. We upgraded the software constantly on our own, we developed the pylons for the air launched version, we modified it for landbased or submerged launch...
The joint development of Brahmos M will include the new development of the engine, possibly even completely by DRDO with Russian assistance, while the long term prospect is the hypersonic Brahmos. Compare all than with the Nirbhay development and you will understand how far we lack behind and how long it might take, to develop Brahmos M or even the Hypersonic Brahmos on our own. That's the advantage of joint developments, it cuts development time, because we gain from foreign know how. That gives us the chance to catch up faster, which we otherwise can't as the LCA development sadly has proven. We might have had success in certain fields, but can't do it alone.
I will believe it when it happens. Other wise its theoretical. All the examples are of assembly. Sometimes Indian components (e.g. guidance systems in Brahmos or dual pulse motor in Barak 8) are added.
And what the problem with that anyway? We have such an dismissal against projects where we only provide subsystems. Look around, most of the developing and even many advanced nations does it like that and are happy. Rafale's SPIKE was initially developed by Germany, Turkey's TAI 129 combat helicopter is based on an Italian helicopter, with US engines and guns, the Japan has made their own version of the F16, Brazilans are modifying Exocet missiles with own propulsions...
We would do much better to develop indigenous AESA and Kaveri engine for Mig 29K upgrades, than for LCA, because the former would be more independent and is the more capable platform, while LCA can't afford more delays by waiting for these techs to be available. But our pride is limiting us, to make our forces more capable and develop our industry faster.
But I still have to see a full TOT (at the material level) critical things like radar, engine.
That's what we now are up to at MMRCA and most likely at FGFA, the first time that we got such deals, since even MKI included only assembling of radars. Now is the time and the chance for us to get so many benefits, we just need to use our advantage now.
Increasing number of jobs is a pretty important thing I would say.
Sure it is, but then the BJP should be honest about it and not claim nonsense things like making Indian independent from imports. Manufacturing parts in India that are not interesting for Indian forces, or not include critical techs to improve our industry, won't make us any better.
The difference between the congress and nda govt policy is huge...
...Where various international companies set up manufacturing for local as well as global market.
Please check the links I provided! It was the UPA that initiated the involvement of local industry it was UPA that increased industrial benefits through higher offset and ToT demands, it was the UPA that aimed on making India to a defence production hub...
You can take the MMRCA competition alone, which even if not finished, brought in nearly all major aero companies to establish either relations to Indian industry or even set up own facilties in India (Boeing on production hubs and deep relations to TATA, HAL and now Reliance, Airbus R&D hubs, ties to HAL or L&T...).
All these things are already available and just use them to gain more with the FDI increase now, but it's far away from being something new.
Self sufficiency will only come if our govt or companies spend massivly in core R&D
If that would be true, China would not need to copy so much foreing stuff, would not be dependent on Russia for engines and would not require Russian and Europeans for 90% of their helicopters. Or the otherside, if money is the only key for successful developments, countries like Israel, S. Africa or Sweden would not be that good in the defence field, since their investments are far lower.
