In responding to a comment about a recently found shipwreck – Wreck of USS Hornet Found, I went to Wikipedia and found two lists: https://en.wikipedia.org/wiki/List_of_missing_ships and https://en.wikipedia.org/wiki/Lists_of_shipwrecks. Some of the shipwrecks are visible on sites such as Google Maps. A good example is the German cruiser Prinz Eugen: https://en.wikipedia.org/wiki/German_cruiser_Prinz_Eugen. You can barely view the ship on Google Maps: https://www.google.com/maps/place/Wreck+of+German+cruiser+Prinz+Eugenemail@example.com,167.6826061,328m/data=!3m1!1e3. It includes a photo on the left side of a close-up of the ship.
Here are some lists of found shipwrecks: https://www.google.com/search?client=firefox-b-1-d&q=how+many+shipwrecks+have+been+discovered+in+the+last+40+years.
I will blog about some of the found shipwrecks as well as post about some that haven’t been found.
