SM UC-6

SM UC-6 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 had been ordered by November 1914 and was launched on 20 June 1915. She was commissioned into the German Imperial Navy on 24 June 1915 as SM UC-6. Mines laid by UC-6 in her 89 patrols were credited with sinking 54 ships.

Fate
UC-6 sailed from Zeebrugge on 27 September 1917 to lay mines off the Kentish Knock and did not return. It was later reported by British patrols that strong explosions had occurred in explosive nets laid in the area that same day. Other sources, however, state that UC-2 was destroyed by a British seaplane on 28 September 1917.
