The Taiwan strait is too shallow for submarines to operate, so in a hypothetical conflict, China's subs will be much further out, trying to keep US strike groups far from the island, while also securing China's supply lines through Malacca.

Note this is one of the material motivations for the CCP gaining control over Taiwan. They'd quite like to move their submarine basing to the east side of the island as a practical matter. It's got deep water and plenty of cliffs/mountains suitable for hardened docks/shelters.

I agree that's generally true and I didn't mean to imply otherwise. Thinking it through, though: if Japan is party to the conflict its naval assets are likely to be much closer to China, and China will need to keep some assets nearby in the East China Sea to honor the threat regardless.

To be honest the thing that's puzzled me about the Izumo-class ships since I read about them and the conversion they are undergoing to carry F-35Bs is where exactly they'd be safe to operate in a conflict against China. It's not like those planes have great range, and it's not like refueling is usually going to be an option, so if they're going to be put to use those ships are going to be in range of an awful lot of stuff. And what a juicy target for China.

Is that true of China's smallest diesel-electric attack subs? I'd think the reason for them not to operate there would be a lack of targets.

edit: I take the latter part back. Apparently mine-laying in the straight by US submarines is hypothetically something that could happen in the conflict, and that would certainly constitute a target for China

Welcome to 2025. How about those unmanned submarines that can be made dirty cheap?
