Nuclear submarines is going to put a rocket up Uncle Xi. Expect some serious consequences from this decision...
He can just be told where to go, it's not as though China don't have nuclear submarines (they're smeg ones, but they've got them all the same), frankly, right now, he needs to be more concerned about the Japanese and their
awesome Soryu, they'll drop his nuclear sub fleet to the sand before the Chinese even know where they are. Incidentally, Australia should have just bought the Soryu 'off the shelf' from them instead of that stupid Naval project that Sean Costello smeg us with.
