I cleaned these up as best as I could, August - October 2014.
List of United States Navy ships <---- Took these alphabetical lists, dropped them all into Excel, did various sorting, find-and-replacing, concatenating, etc. to come up with a list (below) of links to the "What links here" of any ship name article where there were two or more ships with the same name.
Example of template: {{USS|Abraham Lincoln|CVN-72}} points to
USS Abraham Lincoln (CVN-72) and italicizes the ship's name.
{{Shipindex}} gives you "This article includes a list of ships with the same or similar names. If an internal link for a specific ship led you here, you may wish to change the link to point directly to the intended ship article, if one exists."
