The United States maintains eleven of these ships. Given their vulnerability to conventional and asymmetrical threats, more and smaller carriers have been suggested over the years, such as Elmo Zumwalt's Sea Control Ship, and carriers the size of USS America (LHA-6) carrying STOVL and UCAV aircraft. However, supercarriers' advocates consider them to be more cost effective than smaller carriers.
The mobile offshore base (MOB) is a concept for a modular floating military base as large as 10 aircraft carriers. If realized, it could be moved anywhere throughout the world's oceans, obviating the need to seek permission from allied nations for use of land bases. The concept was studied in the 1990s by the U.S. government but was abandoned in 2001 as cost prohibitive.

Of face, without the life to save,
Being from all salvation weaned

Who would come back is turned a fiend
Instructed by the fiery dead.”
