An interesting look at how USN Aircraft Carriers operate and why they are considered so vital for our defense. An aircraft carrier is basically a small city at sea with its own airport. One thing this video doesn’t discuss is that there are a number of Helicopter Carriers in service as well by various nations. These are called Amphibious Assault Ships by the United States Navy as they can deploy Marines for a ground assault. The USN currently has nine helicopter carriers capable of providing air support with F-35B Lightning II stealth strike-fighters or AV-8B Harrier II attack aircraft.
