"...for a sea borne assault..." Not done any more. Think helicopters.
Not quite. Well decks for LCAC (hovercraft), LCM, and amphibious vehicles (AAVs) are alive and well in US Navy amphibious assault ships.
In any case, years ago, the USN was going to put a small flight deck on one of their BB's for Harriers as I recall. It became too expensive to keep them in operation and the U.S. Boat People didn't have the trained and exprienced bodies to man 'em.
Plans for the aviation conversion of the Iowa class had been dropped by 1984.
