SM UC-70 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 12 January 1916 and was launched on 7 August 1916. She was commissioned into the German Imperial Navy on 20 November 1916 as SM UC-70.[Note 1] In ten patrols UC-70 was credited with sinking 33 ships, either by torpedo or by mines laid.[1] On 28 August 1918, UC-70 was spotted lying submerged on the sea bottom and attacked by a Blackburn Kangaroo patrol aircraft of No. 246 Squadron RAF and then was then sunk by depth charges from the British destroyer HMS Ouse.[1][7] The wreck is a Protected Wreck managed by Historic England.
