The only time Pakistan should go for a Aircraft carrier is if , we have nuclear propulsion system vs Petrol/Oil based propulsion
Pakistan Navy reallly has to move in calculated manner
1- Develop ample Frigates to first have a numerical force
2- Train that numerical force on how to coodinate operations
3- Getting 2-3 destroyers later on will help us get trained on
Managing ship of considerable larger scale
4- We still need to properly adapt to strategy of working under the
defensive shield of Destroyers from aerial threats
5- Not to mention we also have to device strategies to use the Orion
effectively from Suk Hoi threats from Carriers
So there is a ample learning curve, if there is a carrier available to us we could get it but we won't have any planes for it for 1-2 years.
Unless our Mirages can operate on carrier ? not sure
But if we can get it would be good investment
But a carrier is something we could live with out for 10-15 years
The amount of fuel the carrier will burn in 1-2 billion $/year could be used to aquaire
Frigates, Destroyers , and also modernize our radars for time being
10/11 billion saved in fuel money alone in 3-5 years perioud could equip the navy with Submarines and Frigates
But if I had the chance to get hand on carrier I would and worry about planes later
