But that's not entirely their fault, I see it as a cultural problem, because just like they have too high expectations on their own capability, we Indians often have too high expectations on "indigenous" developments!
I don't believe Astra will be a top notch BVR missile, but even if not, fitted on our fighters it will make us less dependent on foreign missiles, that might have reliability issues, must be procured at high costs and might not be available in war times. Astra is meant to be a reliable base for Indian fighters, just like LCA, Dhruv, or the DRDO AWACS. If the forces need something better, we can co-develop or procure it, since we have plenty of options.
So even if it's end up with just 80Km range, I would be more than happy, as long as it is reliable and we can produce them in numbers whenever we want!
Astra is a BVR missile with a radar seeker, while manpads usually are SR IR missiles, so that won't work.
