SM UC-13

SM UC-13 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (Kaiserliche Marine) during World War I. The U-boat was ordered on 23 November 1914, laid down on 28 January 1915, and was launched on 11 May 1915. She was commissioned into the German Imperial Navy on 15 May 1915 as SM UC-13. Mines laid by UC-13 in her 3 patrols were credited with sinking 3 ships.

Fate
UC-13 departed Constantinople on 12 November 1915 to operate in the Black Sea. On 29 November, while navigating using dead reckoning due to the adverse weather, she ran aground 55 mi east of the Bosphorous, near to the Melen River. The crew subsequently scuttled UC-13 using demolition charges before being picked up by Turkish vessels.
