SM U-68 shipwreck

SM U-68

SM U-68 was a Type U 66 submarine or U-boat for the German Imperial Navy (German: Kaiserliche Marine) during the First World War. She had been laid down in December 1913 as U-9 of the U-7 class for the Austro-Hungarian Navy (German: Kaiserliche und Königliche Kriegsmarine or K.u. K. Kriegsmarine) but was sold to Germany, along with the others in her class, in November 1914. Under German control, the class became known as the U 66 type and the boats were renumbered; U-9 became U-68, and was redesigned and reconstructed to German specifications. She was launched in June 1915 and commissioned in August.
