CSS Hunley’s crusty image

For more than a century, Confederate States of America’s submarine CSS Hunley had rested on the floor of the Atlantic Ocean outside of the Charleston, S.C., harbor, and covered by encrustations. When it was raised 15 years ago, it looked more like a barnacled sea monster than the world’s first combat submarine to sink an enemy warship. CSS Hunley, which was built at Mobile, Ala., sunk during a winter 1864 battle. On Sept. 17, researchers announced experts had now removed more than half a ton of encrustations; and are working to remove them from the interior. Now, CSS Hunley looks more like the ancestor of the U-boat and today’s submarines. (Source: Washington Post 09/17/15)
