Pakistan may get access to Chinese satellite networks on marine monitoring.
May.
But those aren't omnipotent, those may or may not be given for targeting, and ultimately, it's only the first part of the equation.
China is a friend of Pakistan, but I'd be careful to expect help on Moskva level.
China has relationship with India, ultimately (and both sides try to keep it, feverish indian popular sinofobia is one thing, elites are another). Points of no return aren't likely unless really, really forced.
The problem is that Indian carriers carry 12 MiG-29s and no AWACS, EW aircraft, and tankers for support. Any MiG-29s that are launched in a strike mission are going to do so blind, knowing that they're going to be spotted by any PAF AWACS that are on station, but without any ability to detect the enemy and maybe not even knowing when they're already under attack. It's just far too much risk when the Indian Navy could just lob cruise missiles from its destroyers.
Twice that number, Indian carriers are comparatively small, but not that small. 12-14ish(approximately) is their deckload strike limitation, not capacity.
Their weapons now have significant stand off, and ability of Pakistani AEW to see lo- targets is ultimately controllable (horizon, rwr).
Same unpredictable darting in and out Ukrainian fighters do, but from a fast-moving, unpredictable airfield.
While destroyers certainly can and will launch such strikes, Carriers significantly exceed surface Navy's ability to lob missiles. It's a very simple math - after emptying it's missile capacity, surface vessel goes to reload(i.e. one strike at a time, 8-16 missiles per indian ship).
Indian carrier (assuming 12 pee wave) deckload is 24...48 (cheaper)missiles at more combined stand off and lesser risk(both absolute and opportunity cost), x2 waves, x2 carriers, assuming deck crews are good enough. It can be repeated again and again, until carrier is empty. Moreover, resupplying smaller missiles at sea isn't nearly as hard as resupplying brahmos or calibers.
It's all the more important, because in our context, Indian western coast is simply dangerous to resupply, it concerns both destroyers and carriers.
Pakistan can reach those without too much trouble, and the best spot to catch something mobile is at port.
Long way of saying that a big carrier navy is a pain in the ass to fight against. And Indian navy is a pretty big carrier navy. Just no way around it.
Not nearly on the USAF level, where tanker fleet is on the same order as major tacair communities.
Furthermore, tankers over sea themselves turn into targets. While useful for intensive ops (when we proactively create temporary air superiority through planned allocation of assets), I don't think they can be used to
maintain maritime presence - too much work(tanker isn't airfield ultimately), and they themselves will become targets of interceptions.
We sort of forgot rafales (coastal and soon - naval) after their heavy losses in ill-fated Sindor, but they still can(will?) come with meteors. Fighter can find a way out of ramjet missiles way, but for a large force multiplier, launch is effectively a death sentence.
I.e. I think it is not worth the risk for continuous operations over sea.
Disclaimer: I'm mostly describing situation at hand, now to +3...4 years. With future procurement (fc-31) it may change.
