2 Possibilities,
1)
@Gripen9
Lets make your possibility in Reverse Order , may be Operational needs require to Strike Deep & then not enough fuel to RTB, so they are recovered on carrier.
@Pakhtoon yum
This will be much Less heat for the Dragon (diplomatically) as compared to Launching the Pakistani Flying Sharks.
2)
@Khafee
Here is my imagination and possibility ;
PN / PAF / PN Air Arm train on
Chinese Carrier , & attain a level of self sufficiency in Operating it but Pakistan is not buying or leasing it (at the moment) as our economy & needs / policy does not allow the space to have
one. It is just
Training . It also wont create any Red Flags (Officially) in the WEST as well. We have a good cover of
"Protection of CPEC Sea Routes" which will be a combined effort of China & Pakistan & it will also be safeguarding investment & Assets of our GCC brothers in Gwadar (oil refinery, petrochemical plant etc).
As soon as shit hit the fan or is about to, red army is flown off the carrier ( strike group may or may not have all red army assets at this moment, as it will
take at least a Decade to reach this point, PN might have more Frigates, Submarines while add Destroyers etc to its fleet) & Pakistan announce to the world of leasing an AC or complete CSG from China while Men in Green operate them.
This all may seem childish 7 far fetched but given the circumstances, this is the only Practical (in my naive thinking) use of carrier based J-15 purchased by Pakistan.
Not a $ spent from Pakistan's pocket & we have our needs fulfilled.
PS: PA /PAF / PN make Indian Armed forces shit in their pants at current position while being broke & numerically ( in some case qualitatively ) inferior to them, just Imagine the though of PN having a CBG & what it will do to Indians
