As of June 2022, there are 47 active aircraft carriers in the world operated by fourteen navies. The United States Navy has 11 large nuclear-powered fleet carriers—carrying around 80 fighters each—the largest carriers in the world; the total combined deck space is over twice that of all other nations combined.

There is an increase in aircraft carrier capabilities worldwide. The U.S. Navy still has a massive lead, but China will take the second spot in terms of numbers and size. It faces competition though. Britain has revived its once-pioneering capability, and France is building a newer carrier in the same league as the Chinese ones.
