China would have no trouble making a WWII-era aircraft carriers. That's a ridiculous comparison - to have an aircraft carrier with a prayer of standing against an American one, you need something that can launch jets. A seventy-year old carrier is not going to launch a modern jet.
Actually, the United States has at least one seventy-year old Aircraft carrier (or nearing 70) capable of launching modern jets.
It's currently decommissioned and acting as a museum in San Diego.http://www.midway.org/
The USS Midway (CV-41) was laid in 1942, and commissioned in 1945. It served in the Korean, Vietnam, and Desert Storm conflicts until being decomissioned in 1997. It was one of the last conventional-power driven Aircraft carriers in the US Navy.
As an aside, my father served on the Midway in the 1980s and 90s, and I myself have been aboard her several times (twice while at sea during "Tiger Cruises", when the Navy started letting girls attend).
We also have a significant number of modernized (but mothballed) conventional-power driven carriers, in case we are pulled into a naval war. Carriers such as the Kitty Hawk, Constellation, America, and John F. Kennedy.
So we are in good standing to be able to repel a Chinese naval assault, though it won't be bloodless for us, either. Callie is right to be concerned, considering our nation's dire economic situation right now (which could be extended if the voters don't clean congress out some more, and change tenancy in the White House in next years election).
Matters like these are exactly why I could not, in good conscience, vote for Ron Paul. His view on closing down all overseas American military installations is short-sighted and overall a bad choice. We're in those countries for good reasons, obviously, or we wouldn't still be there.
I think we have better missiles now. An AEGIS cruiser probably packs enough punch to wipe the carrier off the water without ever seeing it. Yes, anit-missile defenses exist but they're not 100% effective. I might be wrong, but I'll ask my brother who was an admiral's aid and now a Lt. Commander. He'd probably have some idea.
Aegis-equipped Cruisers and Destroyers are not necessarily equipped for attacking/assaulting an enemy Aircraft carrier. The Aegis Combat System is intended to shoot down enemy aircraft, using SM2 surface to air missiles. Yes, it is also used to guide and track outgoing anti-surface missiles, but its primary goal is to protect the battle group the Aegis-equipped vessel is in. Not all Aegis-equipped vessels carry Tomahawks, though there "should" (though with our current administration, not likely) be a rapid procurement of the new Rail Gun batteries for Cruisers and Destroyers, soon. That alone would keep the Chinese surface fleet at a sufficient distance.
