This is true-ish but the eleven US supercarriers and their accompanying carrier battle groups are vastly different from any other navy on the planet. Other nations do not have ships of a comparable size. Two UK carriers come closest to the way the US Navy works, but are smaller. Russia's lone, damaged carrier is 25% smaller and may travel with a roughly comparable escort, if and when it becomes operational again. Many other nations' carriers are one half to one fifth the size of a supercarrier. They exist to provide STOL/helicopter platforms.
