Nuclear-powered aircraft carriers are more effective than conventionally-powered carriers for two basic reasons.
One, nuclear power provides more energy for catapults and sensors than fossil fuel; and two, the lack of fossil fuels onboard also frees up a lot of space for more missiles and bombs.
But there are only two countries in the world with nuclear-powered aircraft carriers: the United States and France.
France has one nuclear-powered carrier, the Charles de Gaulle. The US has a fleet of 11 nuclear-powered carriers, including two different classes, the Nimitz and Gerald R. Ford classes.
But the Ford-class only has one commissioned carrier, the USS Gerald R. Ford, and it has yet to see combat, while the USS Nimitz was commissioned in 1975, and has seen plenty.
The Charles de Gaulle, which was commissioned in 2001, has also seen combat for over a decade.
So we’ve compared the tried-and-trusted Nimitz and Charles de Gaulle classes to see how they stack up.
And there’s a clear winner — take a look.
The first big difference between the CDG and Nimitz-class carriers are the nuclear reactors.
Nimitz-class carriers have two A4W nuclear reactors, each of which provide 550 Megawatts of energy, whereas the CDG has two K15 reactors, each providing only 150 Megawatts.
Not only are Nimitz-class carriers faster than the CDG (about 34-plus mph versus about 31 mph), but they also need to be refueled about once every 50 years, whereas the CDG needs to be refueled every seven years.
Another big difference is size.
Nimitz-class carriers are about 1,092 feet long, while the CDG is about 858 feet long, which gives the Nimitz more room to stage and load airplanes for missions. Nimitz-class carriers also have about a 97,000 ton displacement, while the CDG has a 42,000 ton displacement.
This is why means Nimitz-class carriers can carry more than 75 aircraft, such as F/A-18 Super Hornets, EA-18G Growlers, and more.
