If the Cavour is considered an aircraft carrier then why not the USS America class?

Simple question.  Has the Marine Corps been fed a bill of goods?  Why is the Cavour considered an aircraft carrier with a secondary amphibious assault capability and the USS America not?  Stats are again from JeffHead.com

Ladies and Gents, either we have a disconnect in the classification of naval ships and reality or we have a purposeful deception being hoisted on the Marine Corps.  According to the above mentioned website, in a sea control mission organization, the USS America will rival the Elizabeth class carriers being built by the UK.

With the hesitation that is being shown by the Dept of the Navy when it comes to adding a well deck, the question must be asked...is this a ship that will sail away with the big deck carriers when times get hard---taking its compliment of F-35B's with it to perform the sea control mission?

A simple recommendation.

Stop building the USS America class after the first ship is commissioned.

Go back to the drawing board, simply build enlarged versions of  the existing LHD's (with appropriate updates) and be done with.
