IAF is not satisfied with the LCA because they want improvements. They would have never considereg JF17 for the same reason.
But few people here talk as if JF17 is worlds most advance ac on par with 5th Generation AC's available.
When India tested agni IV, very few or no trollers showed up But for this thread the troll bregade lined up.
Its always better to evaluate everything then to hurry. The LCA will do it one day, 2014 is not too far.
ICBM's dont use "seeker" as its target is not a moving one or small like ship or radar communication systems.
I would like if any senior could elaborate on this.
