The German torpedo ship, a Schnellboot type S158, was hit during Allied bombing of Šibenik in October 1944. Two soldiers died, and the ship floated for three days before it was sunk by the Germans themselves. The ship has remained at the bottom of the Šibenik Channel for 70 years and is very well-preserved.
Divers from the Department of Underwater Archaeology at the Croatian Conservation Institute, in cooperation with the Adriatic diving service and Zagreb diving club ZG SUB have been investigating the wreck, which was discovered by local diver Zoran Delibašić, who published the photo on the internet.
