SM UC-66 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 15 July 1916. She was commissioned into the German Imperial Navy on 14 November 1916 as SM UC-66.[Note 1] In five patrols UC-66 was credited with sinking 32 ships, either by torpedo or by mines laid. UC-66 was sunk by HM seaplane No. 8656, a Curtiss Model H-12,[6] off the Isles of Scilly on 27 May 1917. The wreck was found by divers in 2009. This is a notable early aircraft success against a U-boat.[3]
