Which ones? F-22Ps don't have endurance (around 25 days in defensive role) to be there for long and all other ships (leaving OHP) are not fully operational now they are hardly point air defense ships now, which means that PN is now at acute shortage of surface combatants.
These days PN is in really bad shape to do this kind of job specially in distance water, it need new advance and powerful ships ASAP.
Pakistan should keep away from others wars, no one will come to help us and no one respect us. We should keep upgrading our military and economic capabilities and clear our home first.
