Fighter/bomber jets are not directly operated by PN but by PAF, so funds are allocated separately for both forces. As per current scenario at least after having subs/Type 54 PN shall be in position to strike and defend as expected SAM on PN Type 54 expected to be 70+KM HQ16b variant, meanwhile eight subs with capability to fire CMs having range of 600 to 800 KM from different areas, depth of ocean are quite required in short term. It is your right view that they should have got some assets till now.
It is more of responsibility of PAF to get some heavy jets for naval duties, perhaps the time has come for old Mirage Vs to at least say them good bye in case of naval roles immediately. Mig 29K of India are quite modern and cannot be handled in 1 to 1 encounter by Mirage-V.Meanwhile so far we have perhaps only JF17 squadron designated for naval duties.
PN should immediately upgrade it's existing F22P fleet and OHP with any medium range capable SAM, may be Russian naval combo of Gun/SAM are quite capable otherwise South African path is also open though expensive.
