The 42-kiloton Russian VTOL cruiser Kiev, launched in 1972, was the terror of Tom Clancy novels and the boardgame Sixth Fleet when I was in high school.
Now it's a floating theme park. In China.
By comparison, CVN-65 USS Enterprise, "The Mobile Chernobyl", should have at least two more deployments in her before she heads for retirement sometime around her 50th birthday.
The Chinese may have other plans for the Varyag, however...
Of course, like nuclear subs, an aircraft carrier force is not something you just whip up out of nowhere. There's a lot more to it, especially in the fields of crew training and doctrine, than just possessing the gear. You could hand me the most accurate rifle on the planet and I'm not going to step out on the grass at Camp Perry and win a President's Hundred tab.
Speaking of aircraft carriers, here's a picture of the now-decommissioned USS Forrestal with the VSTOL carriers HMS Invincible and Spain's Principe de Asturias, as well as a giant floating can of whoopass:
VSTOL carriers are just tiny by comparison with the bird farms.
