I'm kind of sceptical about some of the hype being generated by some on both sides.Hey Gary,
We were thinking at SDF that it was pretty stupid for PLAN to have a SSK that close to carrier group, since USN can get more accoustic readings on it. I guess what you are saying is that they already have enough knowledge on the capability of Song, that this incident doesn't show more?
the reality is that both sides sniff whenever the other side is running an Ex. Its of mutual convenience. That means that the harvesting is two sided. The training areas are known quantities, so the assumption is that someone else other than the USN would try to have a nose around. Its common sense to assume so. A contact would be expected.
if the USN was asleep at the wheel then you'd question capability - but the USN has historically played against a far more enthusiastic foe (soviets) in the halcyon cold war days - so they know what to expect. The Soviets used to try and steal sonabuoys etc... . I genuinely don't believe that they were t-boned by a surprise guest.
the fact that the sub popped up mid task force is just plain dumb. there is more merit in staying submerged and to continue to harvest data rather than give away your position, and give away potential capability. It makes no sense at all to telegraph latent competency.
I do strongly suspect that this has been overplayed by some as representing either a respective increase or decrease in competency by whoever side they favour.
Just because an intruder is detected, doesn't mean that you react - the USN and NATO regularly didn't react to a presence as there was more benefit in "watching".
What that sub did legitimise was for any "opposing vessel" to visibly react - that does not auromatically signal surprise.
From a purely academic perspective, I'd argue that it creates a vehicle of opportunity for the USN to legitimise a greater spending spree - and that was a pretty stupid thing to trigger (if you're the PLAN).
Ditto for the PLAN - in that the existing Adm (or more correctly General) of the PLAN can now argue for greater spending on subs and undermine the argument for a Carrier (as the pet project for prev PLAN commander, Liu)
