Well, I think we have learned something about the original topic from this off-topic extravaganza. The PLAN needs better ASW, as well as better below surface offensive capability. I talked to a guy who flew p-3 Orions out of Subic Bay in the Phillipines. He said that the PLANs subs were easy to track, didn't get out of port too much and knew they were vunerable, so they didn't usually leave costal waters. He was much more concerened about Soviet subs out of Camn Ranh Bay in Vietnam. He left field duty a while ago, but allowing for the improved capability of both sides, it is still generally true.
I would also like to point out that the USNs subs were able to repeatedly penetrate Soviet "safe zones", such as the White sea, the Sea of Okthosk, the Gulf of Finland and the Black Sea. They were even able to get to the entrances of Soviet bases such as Murmansk, Vladivostok, the Kronsdat (I think that's what its called), and others. The Soviets had ASW capabilites that were superioir to what the PLAN has now, and USN subs were still able to get into the most heavily guarded areas the Soviet Navy had to conduct clandestine operations, such as tapping the underwater telephone cable from Petropavlosk to Vladivostok and releasing divers into the headquarters of the Soviet Navy's European Fleet at Murmansk. Sure, the Soviets did some of the same things to the Americans, but no one ever said a PLAN sub wasn't gonna get an Anerican ship or two if that dreaded war ever breaks out. Does the PLAN have anything to compare to this sort of experience? Moreover, we can see that the USNs subs defeated an enemy more prepared than the PLAN is now 20 YEARS AGO. The US might lose a sub or two, but they would definately be able to penetrate PLAN defences and launch cruise missles.
