The US are definitely the masters when it comes to the conventional aircaft carrier. As pointed out by others on this thread, only France and Brazil have conventional carriers that have catapults and arresting gear.
Brazil's
Sao Paulo was formerly the French
Foch. The Brazilians also bought a squadrons' worth of upgraded A-4's (they called them AF-1's)
http://www.skyhawk.org/2C/Brazil.htm . They actually had to train their Navy guys from scratch, SH-3 and S-2 guys, because the Navy had not had fighters since who knows when? I think they even had to change the law so that the Navy could fly planes, I think only their Air Force could have fighters by law before they changed it. The last I read most of the A-4's were going to be laid up due to a lack of funding.
France is the only other country that has a competent conventional carrier force, though right now it is centered around only 1 carrier. The Rafale is a pretty good fighter and once they get the fighter-attack version they will have quite a punch. Ironically, when they had to test the carrier version of the Rafale they had to use the catapults at NAES Lakenhurst, they are the only land based examples left in the world. They are actually looking at building a 2nd carrier with the Brits, it will be very similar to the
Queen Elizabeth class, of which the UK is planning to build two if they keep the funding intact.

The
Kuznetsov uses a hybrid system for launching and recovering aircraft. It launches aircraft on a ramp but it uses retracktable blocks (that is the only way I can think to describe them) and uses arresting gear to land the aircraft. The last time it took part in fleet ops was Sept 2005, they lost a Flanker during that cruise.

The UK has 3 VSTOL carriers and use them well and often, unlike most of the other countries that have them. One is laid up in reserve until the end of this decade and they use the RAF's Harrier GR.7/9's (very similar to AV-8B's), they retired the last of their Sea Harriers last month

Italy and Spain both have VSTOL carriers and a squadron of AV-8B's, Italy is building a second VSTOL carrier soon. Thailand also has a VSTOL carrier, built by Spain, with a squadron of AV-8C's. I talked to a USMC Harrier guy and he said they were pretty scary when they flew them....
And India has the
Viraat and a squadron of Sea Harriers. They are buying the former
Admiral Gorshkov,
http://en.wikipedia.org/wiki/INS_Vikramaditya being converted to a conventional carrier right now, and a squadron of MiG-29K's (the carrier capable version
http://www.globalsecurity.org/military/world/russia/mig-29k.htm) on order. They have been talking about building a carrier of their own for years and have planned to put their Light Combat Aircraft
http://en.wikipedia.org/wiki/Light_Combat_Aircraft on it, but have yet to get their act together.
Other than that, other countries have some helicopter capable but no fixed wing aircaft to go on them.
I hope that answers your question........
