Absolutely nothing new there. They even announced when the Varyag was going for its sea trials. It is essentially a testbed for future carrier operations and acquisitions by the PLAN. As far as secrecy goes, the Chinese have been fairly open about their intentions.
not so. everyone else has had a fair idea of what their intent was due to the fact that they had this obsession with buying second hand flat tops for fun parks, and it was pretty apparent that they weren't setting a trend in new amusement park concepts
One aircraft carrier with an unfamiliar crew versus the US Pacific Fleet, I hardly think there's any contest or reason to consider this a threat. I'm not even sure what aircraft the Chinese have that are capable of using a carrier deck. This is, if anything, a symbolic threat because it symbolizes that China will be looking to expand its carrier fleet from the Varyag.
Its not about being a threat to PACOM, (the largest single military command in the PACRIM), but is about making the neighbours twitchy and then about the geopolitics of keeping everyone from going off the rails in response. eg China has basically had a disagreement with nearly everyone in the PACRIM in the last 20 years, the only country that hasn't have been the Sings.
eg Vietnam has just elected to buy more Russian skimmer kit, is obviously getting closer to the russians as a counter to the chinese and basically doesn't give a toss about how big china is as because from their perspective, they've punched them on the nose a few times in the last 30 year s and will continue to do so if they think sovereign rights have been challenged over the Spratleys etc...
The filipinos are also looking at more serious kit and obviously seeing that they can get the support of the US on sovereignty issues, the indons and malays also have issues with chinese claims on the Spratelys and Paracels. In fact 6 countries in the PACRIM are in disagreement with the Chinese over those territorial boundaries
No need to get so wound up over one carrier. In itself, the Chinese Varyag hardly does anything to the balance of power.
for the US it doesn't, for the smaller nation states who have already and regularly exchanged fire with the PLAN or various chinese alphabet units it is because it demonstrates latent intent to project, persist and now reinforce that naval capability with fast jet air support, as well as a capacity to go out and sieze and hold by landing chinese marines.
its not a game changer for PACOM at a military level, but its a game changer at the strategic and ultimately tactical level for all the smalls.
