The thing is the navy would be looking to retire the old Agosta 70's, and therefore this urgent replacement prompted the order for the submarines. The 054A's will be coming, especially since Pakistan has started the early phase of building the lighter F22 frigates. I suppose the next deal will be for a considerable number of frigates to increase the size of the surface fleet. I'd go as far to say that if Pakistan had the budget to completely create a new air wing for the navy that is in excess of 60 planes. They train amongst themselves, they fly patrols, sorties etc and have nothing to do with the PAF.
