Naval history is full of fatal accidents and wartime losses. Even knowing that, it's astonishing to think that, according to a United Nations report, there are more than 3 million shipwrecks on the ocean floor. Of course, most of them will languish, unexplored and invisible forever, but, fortunately for us, many of them have been cataloged and photographed. These are some of our favorites.
