In the PN the MILGEM Ada will basically serve in a similar role to the F-22P - i.e. AShW and ASW.
The Type 054A is the AAW asset.
So the PN will have the capacity to raise four 3-ship flotillas, each with 1 Type 054A (AAW, ASW and AShW) + 2 F-22P or MILGEM (ASW/AShW). You could add Azmat FACs into those as well for further offensive capability.
In the end, it's about A2/AD, not sea-control.
So I expect every PN surface asset to operate in close proximity with the 054A, with the 054A offering AAW umbrella while the smaller ships (e.g. F-22P, MILGEM and Azmat) fire long-range AShM (covering the extent of Pakistan's EEZ, but from within a safety zone covered by the 054A + ZDK03 + JF-17).
