The US Has More Carriers Than the Rest of the World
The United States had more aircraft carriers than the rest of the world put together at the height of its carrier armament. In fact, they had ordered more than 150 of them during World War II. By 2021, the United States will have to make do with a few less carriers overall, but it will still have one more than the rest of the globe combined.
The US has 11 carriers in its fleet at all times, as we already mentioned. There used to be 15 people working in services, and it's feasible that number will rise once more. However, the US currently leads with 11, and China, the UK, and Italy tie for second place in terms of fleet size. Two aircraft carriers are present in each of the three nations.
France, Russia, Spain, and India, which each have one, are tied for third place. The end of that. Despite having had few in the past, no other country now maintains an operable aircraft carrier. Brazil, as an example.
