As said in the post above, the crucial point is IAF's lack of AWACS support (we waited too long for DRDO AWACS) and offensive strike capability. That will highly limit IAFs capability to defend our air space and to do pre-emptive strikes beyond the ground based Brahmos range of IA today.
well consummation of MMRCA deal significantly enhance our offensive capability at least to some extent...
and that's why it's so crucial....
But MMRCA will do good to us in only short run .
AMCA has to live up to expectations if we have to have reliable capability vis a vis PLAAF .
