Martin PBM flying boats, two seaplane tenders, fifteen other aircraft, thirteen US Navy support ships and one aircraft carrier; the USS Philippine Sea

It seems incredible that so shortly after a war that had decimated most of Europe and crippled global economies, an expedition to Antarctica was
undertaken with so much haste (it took advantage of the first available Antarctic summer after the war), at such cost, and with so much military
hardware - unless the operation was absolutely essential to the security of the United States.
