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 for production 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 three patrols were credited with sinking 3 ships.

Design
A Type UC I submarine, UC-13 had a displacement of 168 t when at the surface and 182 t while submerged. She had a length overall of 33.99 m, a beam of 3.15 m, and a draught of 3.06 m. The submarine was powered by one Benz six-cylinder, four-stroke diesel engine producing 80 PS, an electric motor producing 175 PS, and one propeller shaft. She was capable of operating at depths of up to 50 m.

The submarine had a maximum surface speed of 6.49 kn and a maximum submerged speed of 5.67 kn. When submerged, she could operate for 50 nmi at 4 kn; when surfaced, she could travel 910 nmi at 5 kn. UC-13 was fitted with six 100 cm mine tubes, twelve UC 120 mines, and one 8 mm machine gun. She was built by AG Weser Bremen and her complement was fourteen crew members.

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 nmi 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.
