3-4 squadrons of 4++ gen fighters is the bare minimum we need to be able to put up any sort of air defence. This by no means is sufficient.I second getting the F-16V first as well. Maybe four squadrons would do it but I am no aerospace strategy expert.
The point is, we have to have some capability in the F-16V to carry long range maritime strike missiles, I have to research that to see whether US or Turkey offers such a munition...in this sector PAF could be our role model as they also operate the F-16 but maybe not in that role.
Right now we lack a deep maritime strike capability. Deep meaning within 40 miles of any target that violates our maritime zone.
F-16s can perform limited maritime strike within the EEZ with aerial refuelling but cannot clear out a naval blockade near Andaman. We will need a combination of attack submarines, heavy frigates, ballistic missiles, drones and twin engine fighters to defeat a naval blockade - a pipedream till 2050.
