Has it started for the MKI yet?? I mean with all the raw materials scoured and complete production in house??
Yes it has started from around 2010. I am 100%sure. Plz google for links but be assured its a fact. And the no of SU-30MKIs being churned out has also increased from around 9 per year to around 30. The Remaining 115 MKIs will take around 4 years to complete it's delivery ie by 2016. U can verify the year 2016 from several sources.
Its fine if it comes by 2020, I mean by teh time it will be fully developed and tested. for a 5th gen fighter its all testing. You dont wanna get a plane which just flies.
Exactly, we don't want just a rudimentary VLO aircraft. We want a decently matured platform with mature 5th gen Engines ( the current Saturn-117 is just Al-31 on steroids. not a true 5th gen engine IMO )
Also, sukhoi needs to work on it's stealth characterstics from the back and below.
Also, several BVR missiles will complete their test by then and work can also start on Air launched hypersonic brahmos by then depending on the doctrine and platform capabilities. etc.
