nothing wrong with asking a military related question or strategy
F22P gives PN a new reasonably well equipped all round surface combatant, it is not strong in any particular field but does provide significant capability’s over previous generation of ships, more importantly it also provides a platform which will be upgraded in future with likes of FL-3000N, a more advanced re-loadable SAM, powerful hull based sonar, UAV, etc etc
A TAS is not favourable to Arabian Sea conditions close to Pakistan shores because PN already did research into this and salinity/temperatures and conditions makes TAS not a worthwhile investment
In addition with a Z9 anti-submarine helo and the capability to link to the FFG, F22P does have reasonable offensive capability
What will it do in time of war? Well it certainly will not be sailing out into deep oceans far from friendly shores and engaging Indian Navy in open water, they will be operated solely and independently, but within air coverage hopefully
The limitation in the F22P when compared with advanced Indian FFG and DDGs is nullified when you see the likes of ZDK-03 stationed at PAF Base Masroor (near Karachi) where a squadron of soon to be JF17 will be stationed equipped with air launched anti-ship missiles, also there are shored based battery’s equipped with anti-ship missiles, mainly C-802
This AWACS + JF-17 (C-802) combination is really the asset that Pakistan will be relying on to counter the Indian Navy, fast jets that can fire from a stand-off distance long range missiles, to any modern navy will see havoc not to mentioned likes of the air launched Babur cruise missile which is operational too
PN fleet will be held tight, a high guard for defence, the flexible air component will act as the offence, where it can swing around the Indian Navy and sweep in hitting hard and fast, a single naval squadrons of JF-17 can launch over 30 x C-802 missiles, even (in the very unlikely scenario) if 15-20% get through that’s 5-6 missiles minimum, enough to cripple or damage 2-3 Indian surface vessel and that is in a single wave, the naval squadrons are very highly trained max sortie rates and can be turned around to go again day/night
Therefore the need for a Type 054A FFG is really not there as the strategy will be the same
