PAF will use ZDK-03 AWACS to track ships & air assets and IN CBG far from its coast will not be in good position to create a long distance effective defense zone, PAF already have 50+ JF-17s + Mirage-V with IFR capability which can be used for quick strike on CBG with super sonic & subsonic AShM remember that ARM version of YJ-12 is also available to PAF they can get it when required and it can hit targets from long distance so there goes your Agies class ships, PN & PAF many time in past have breached USN CBGs defenses undetected in exercise so how IN can think that they can handle PN so easily. PN already have plenty stock of missiles available as they know they will need them in good numbers, and its not necessary to sink a ship or ACC just enough damaging them that they are non operational during war will do the job.
Not easy as last line of defense of PN will eat your assets will try to come close, PN have potent firepower when it comes to block Op Phthon class ops of IN, I will love to see MRTP-33s hunting with Azmat class boats.
