Including amphibious assault ships (LHA), there are now 47 active aircraft carriers in the world, operated by fourteen navies. More than a third of the flattops are in service with the United States Navy, which maintains eleven nuclear-powered CATOBAR carriers, including ten Nimitz-class and one Gerald R. Ford-class.
In addition, the U.S. Navy operates two America-class LHAs of a planned 11; as well as seven Wasp-class ships – while an eighth was seriously damaged by fire and subsequently decommissioned last year.
