USS goes in front of the name of an American navy ship to show that it belongs to the United States government: USS Enterprise, USS Missouri, USS Cole. It is a title, not a word you use on its own — you would not say 'a USS' — and it is used only for warships that have been officially put into service, so a ship being built is not called USS yet. In careful writing you say 'the USS Nimitz' or just 'USS Nimitz'; naval people usually drop the 'the'.
