According to various military histories, the US still has the 8 bases that the British traded. Of the 50 destroyers given to the British for the bases, they were most likely scrapped or re-purposed or destroyed during the war- they could be tracked down if you like through the Wikipedia article which has the names of the ships. A few good links: http://en.wikipedia.org/wiki/Destroyers_for_Bases_Agreement http://www.history.army.mil/books/wwii/Guard-US/ch14.htm http://globalpublicsquare.blogs.cnn.com/2011/09/02/destroyers-for-bases-fdr-churchill/

As far as these say, the United States remain in possession of these bases.
