I think w may know enough in a years time to be able to say one way or another.We can revisit this discussion in five years to see how the Tejas is progressing, or not.
I twill all hinge on if the Indian's accept the F-16 deal.
if they do...they will build a lot of F-16s and with Lockheed's help, will build a plant capablke of procucing more aircraft per year...perhaps as many as 40 per year at a minimum if they want to.
That will not necessarily kill the Tejas. it is still an important thing for the Indians to do...on their own in developing their own indigenous capability, learning from it, and advancing beyond it.
The F-16 production going on in India will also help in that regard.
And, quite frankly, the have so many legacy aircraft to replace...they will need the full production of both plants.
Mig-21 - 245
Mig-27 - 120
Jaguar - 145
MIrage 2000 - 50
That's 560 aircraft right there they need to replace during the 2020s.
BTW, Tejas is set to go to 16 per year in 2017 or 2018 I believe.
