The German sub sank 76 years ago. Now its story is being revealed in eerie fluorescent detail.

The U-boat seems to loom out of the blackness, careening to starboard, as if to avoid a collision.

As it glides by in the image, its deck gun is unmanned, its conning tower empty, the wooden deck plates are rotted away.

It is German submarine U-576, Kapitänleutnant Hans-Dieter Heinicke, in command.

And as it “passes,” its outline appears in laser-generated colors of fluorescent blues and greens.

It’s a ghost ship, resting in darkness in about 700 feet of water off North Carolina since 1942, with Heinicke and 44 sailors entombed within.
