SM UC-25 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 29 August 1915 and was launched on 10 June 1916. She was commissioned into the German Imperial Navy on 28 June 1916 as SM UC-25.[Note 1] In 13 patrols UC-25 was credited with sinking 20 ships, either by torpedo or by mines laid. March–September 1918 she was commanded by Karl Dönitz, later Grand admiral.[4] UC-25 was scuttled at Pola on 28 October 1918 on the surrender of Austria-Hungary.[1]
