I too have read many list of,and about these secret bases not only here in the U.S.A.,but worlwide.Who would benifit from such rumors,and how were
they known to exist? They say most are under mountains,airports,university's,privatly or goverment owned land & buildings.as well as the vast oceans
we know very little about.so its possible,I suggest, if the rumors do go back decades,and there are places that you listed could hide entrances.
