India, even by their own projections, will only field 2 carriers for the next 20 years. Both former Soviet designs, both with very limited air wing and rusty MIG-29s. If anything these will be more of a liability then an asset. India will need sub and destroyers to protect them. Their effect on a short, sharp India/Pakistan war will be zero. Just like we did not hear anything about the carrier they do have during Feb 27th.
Thanks to long range shore based Anti-ship missiles with 400km range, Indian carriers will have to station at least 500km off our coast. Combat range of MIG-29K is 850km but much less depending on load. Serviceability of the MIGs is between 16%-36% according to Indias own reports, so of the 42 remaining, only expect around 10 combat ready, of these 10 they will hold back 6 to defend the carrier (2 in the air, 2 on deck ready to replace them and 2 in reserve), that gives them 4 Migs to fly over Karachi
Then if they make it to our coast they will get welcome from SPADA 2000 SAM and JF-17s.
I have not even talked about the threat P-3C and Subs can present to such a big target.
If they lose one carrier it will be the biggest ever blow to Indian national pride since 1962.
These carriers are for prestige, nothing more, nothing less.
