Well according to some reports by the CIA in the Cold War era when America were at it's peak, the US battle group will last no longer than 48hrs in a real battle with the Soviets.Aussie Digger said:Anything's possible. Australian F-111's have scored successful (notional) Harpoon missile hits on US aircraft carriers using a combination of high speed and an extremely low level ingress, during a number of exercises off the coast of Australia.
RAN Collins Class submarines are also rumoured to have penetrated the USN's defences and scored torpedo hits on US carriers on a number of occasions.
This does not mean however that it is easily done, a fact that should be obvious given that no-one has even come close to damaging a US carrier since WW2. US carriers are extremely well protected by their own aircraft and their supporting platforms.
I think China would find it very difficult to cripple or otherwise disable a US Aircraft Carrier, but I wouldn't say it would be impossible for them to do it... It would have to be a fully thought out operation though. The retaliation that would come if a US aircraft carrier was damaged or even sunk, would be horrendous...
So it seems like the Americans are somewhat overrated.
The PLAN currently is no where near the Soviet navy's capabilites in the 70-80's, but please we're take into account that the US navy is at China's door step. There are heaps that the PLAN can throw at the Americans. They may be considered 'obselete', but I'm sure a gun in the WWII era can blow your head off just as effectively as an OICW can in close range.
