God knows, i doesn't make any sense, the two new CLV future carriers of the royal navy individually cost more than a typical nimitz class supercarrier, and yet they have no nuclear power and carry half as many planes. Maybe things are just more expensive to build in the U.K. Idea!!, scrap the CLV and buy two nimitz class carriers new or old.
Designing and building new aircraft carriers is expensive. That's why few countries build them. The design costs are spread among two UK carriers but among many Nimitz class carriers making the UK ones appear more expensive. We could buy a couple of US carriers instead but then we would lose carrier building capabilities in our own shipyards. That's a strategically bad idea. In addition, the Government gets much of the money back anyway via taxes, both personal and corporate.
The airwing may be a lot smaller, but would the RN have the money for 200 aircraft anyway? Or even need that many? Not to mention the additional pilots, crew numbers etc etc.
The new carriers are not nuclear powered because we don't need them to be. With bases throughout the world fuel supply is not an issue. The expense is not justified. The existing carriers are conventionally powered and that's never been an problem. The only time it would matter is if the bases fall. In those circumstances, it would be a world war and likely go nuclear rendering the carriers pointless in any case.
On an additional note, the Royal Navy has suffered in recent years from cutbacks in funding from the MoD. While the UK's new CLV carriers will be second in the world only to the US Nimitz class, the RN's funding shortages make the uneconomical cost of building these new carriers evenmore unfeasable. Also, since they cost such a significant amount of government money, why not shell out the extra money and make the carriers nuclear powered anyway? After all, the Royal Navy already has other nuclear powered vessels in its fleet.
Comparing these new carriers with the Nimitz class of carrier is not a valid comparison. The Nimitz was laid down in 1968 and commissioned in 1975. Yes they have been upgraded to an extent, as new ones have been built, but because of the original design there are limitations to the extent of upgrading possible or practical. Comparing these two very different classes of carrier is like comparing a slingshot to a rifle.
A more accurate comparison would be the class of carrier being developed and built at the moment, like ours, to eventually replace the Nimitz class, the first of which will enter service in 2015 to replace the Enterprise. The Gerald R. Ford class of carrier was estimated in the last report to cost $14 billion. Just over twice the last estimate for ours.
As for the nuclear question: In addition to that which was written above about our not needing a nuclear powered surface fleet there is a great saving involved. The first of the Nimitz class will be replaced by the 2nd Gerald R. Ford class in 2025. At which point the Nimitz will be de-commissioned and is estimated to cost from $750 to $900 million to do so. This compares with an estimate of $53 million for a conventionally powered carrier.
The value of air supremacy in a defensive or offensive role over land or at sea, for which these wings would contribute to all four roles cannot be over-emphasised, and I believe, despite the cost, represent good value for money. I believe the security these carriers could provide outweighs for example the comparible money being spent for the Olympics. For the first time in over half a century we may have new carriers that could afford to send an effective flight forward while leaving enough behind for defence, very unlike how our current class of carrier, along with Hermes operated in the Falklands conflict.
CV is for Aircraft Carriers. CVN is a Nuclear Powered Aircraft Carrier
The US Navy no longer has nuclear powered cruisers or destroyers. The only nuclear powered surface ships are aircraft carriers. In general, the nuclear powered cruisers/destroyers could achieve speeds in excess of 30 knots (34 Miles Per Hour). Aircraft carriers must be able to achieve the same speed in order for them to be able to launch and recover aircraft.
CVN is the designation for nuclear powered aircraft carriers of the United States Navy.
aircraft carriers are nuclear-powered. they can last up to 20 years at sea before needing a refresh.
CV is the hull type designation for an aircraft carrier. This is not to be confused with the aircraft carriers of today, which are CVN. The 'N' stands for nuclear powered. CVs were conventionally powered with boilers.
The US Navy's Nimitz-class nuclear-powered aircraft carriers can generally hit a top speed of 30+ knots. Current carriers from other countries generally have top speed in the 25-28 knot range.
The aircraft carriers of the United States don't use gas or diesel for propulsion. They are powered by nuclear reactors. They do carry large quantities of fuel for their aircraft and support ships.

The U.S.S. Enterprise, CVN-65, was the first nuclear powered aircraft carrier. A link is provided.
Most modern submarines use a nuclear reactor as their primary source of power. While I can't be absolutely certain, I suspect aircraft carriers are powered by them, as well.
Some 140 ships are powered by more than 180 small nuclear reactors and more than 12,000 reactor years of marine operation has been accumulated.Most are submarines, but they range from icebreakers to aircraft carriers.
Nuclear power provides the power for more advanced systems, better crew habitability, and the ability to go years without refueling actually lowers costs over time than if the were powered by conventional means.
Most records about Nuclear Powered aircraft are classified, just like the Nuclear Submarines. The United States has only published one record of a Nuclear Powered aircraft. The program was cancelled in 1958, due to complications.
Nuclear plants are too heavy, because of the shielding required
They mostly use nuclear reactors now but formerly they used DFM. That is a marine grade diesel fuel. Some carriers are still diesel powered.
The "weight" of a modern US Navy nuclear-powered aircraft carrier is expressed as its "displacement". The latest class of carriers, the Nimitz class, has a displacement of more than 97,000 tons (long tons) or 98,000 tonnes.

THey are nuclear powered, the fuel they carry is for the airplanes
Two nuclear-powered aircraft have been tested, but none have been placed in series production or service. The two aircraft are now out of service. They used to belong to the United States and the USSR.
She is literally one-of-a-kind. In 1958, they planned to make six nuclear-powered carriers and call them the Enterprise class carriers, but they cost too much so they only made the one named USS Enterprise. Nimitz class carriers were built later. Although the Nimitz class carriers are loosely based on the USS Enterprise, the USS Enterprise is not in the Nimitz class and is quite different. So, no. The USS Enterprise is not a Nimitz-Class aircraft carrier.
US carriers have been using a steam powered catapult since the first introduction of catapult assisted aircraft launch. THe newest US Carrier, USS George Bush, uses an electro-magnetic railgun style launcher.
1945 was the beginning of the ATOMIC AGE; the beginning of ATOMIC POWERED machines (submarines, aircraft carriers, etc.); the Korean War (man's first "Limited War"-fought with the limitations of NO NUCLEAR WEAPONS), and the SPACE RACE.
