Haha. You didn't get what I said. You need a carrier to fight China. And having a carrier makes you a blue water navy. So you need to be a blue water navy to fight China. That tag is very important.
A 65k T carrier is the minimum you need in order to compete with a 100k T carrier. The 100k T carrier and handle more missions, that's all.
Meaning, a 65k T carrier is needed as a minimum in order to attack the CBG of a 100k T carrier. All its resources will then be dedicated to defeat the enemy CBG. But a 100k T carrier can use half its assets to fight the CBG of the 65k T carrier while also attack another fleet elsewhere with the other half. Overall, it doesn't make much of a difference to us because our intention is to only fight another CBG, so a 65k T carrier is more than enough.
You are making a considerably large mistake. The Chinese cannot operate their SSKs in the IOR, it's too far for them. The only SSK that can pull off such a long distance mission is the SMX Ocean, and the Chinese have none of those. SSKs are meant for patrols right outside the harbour and a few hundred kilometers around it. At best, you can snorkel your way to elsewhere and then go underwater again, but that's pointless when up against the IN.
So what I'm saying is, any Chinese SSK will have to snorkel its way through the SCS and into the IOR and then go underwater. Snorkeling makes the submarine useless as a warfighter. And SSKs have significant range and speed restrictions, they can only choose either, not both.
As I said, they are broke, so they are taking their surface ship expansion slow. But their goal is the same as what the USN and PLAN have.
Did you forget the Soviets also had grandoise carrier plans based on the Ulyanovsk class?
We do have expeditionary requirements. Why else are we buying 4 LHDs? We need the full gamut of capabilities the USN has. All major powers want what the USN have.
A 3rd carrier gives us 24/7 presence at sea.
We can make do with the number of SSKs we have for now. And we most definitely do not need 40-50 subs. Especially given the limitations of SSKs, as pointed above. What we really need are more minsweepers, anti-sub corvettes, tons of helicopters and P-8Is, which we are getting.
24 SSKs means we can have 12 in the Arabian Sea and 12 in the BoB. That's already overkill. Even 9 each is a lot, never mind 20 each.
And I wouldn't pay too much attention to Pakistani subs.
