'''SM ''UC-27''''' was a German [[Type UC II submarine|Type UC II]] [[minelayer|minelaying]] [[submarine]] or [[U-boat]] in the [[German Imperial Navy]] ({{langx|de|Kaiserliche Marine}}) during [[World War I]]. The U-boat was ordered on 29 August 1915 and was [[Ceremonial ship launching|launch]]ed on 28 June 1916. She was [[Ship commissioning|commission]]ed into the German Imperial Navy on 25 July 1916 as SM ''UC-27''.<ref group=Note>"SM" stands for "Seiner Majestät" ({{langx|en|His Majesty's}}) and combined with the ''U'' for ''Unterseeboot'' would be translated as ''His Majesty's Submarine''.</ref> In 14 patrols, ''UC-27'' was credited with sinking 58 ships, either by torpedo or by [[naval mines|mines]] laid.

SS ''Skifted'' left from [[Mariehamn]] at 8:30 o'clock 14 December 1916, carrying 56 military persons, 7 workers, 15 members of the crew, and 13 civilians, a total of 91 persons. One hour later it was hit by the sea mines laid by the ''UC-27'' and sank soon near Ledsun on the territory of the Lemland municipality of [[Åland]]. 86 persons died.<ref>[http://www.turkusteamers.com/ulkomaanliikenne/skiftet/laiva.html laiva]</ref>

''UC-27'' was surrendered to France on 3 February 1919 and was [[ship breaking|broken up]] at [[Landerneau]] in July 1921.<ref name=UC-27 />

==Design==
A [[Type UC II submarine]], ''UC-27'' had a displacement of {{convert|400|t|LT}} when at the surface and {{convert|480|t|LT}} while submerged. She had a [[length overall]] of {{convert|49.45|m|ftin|abbr=on}}, a [[beam (ship)|beam]] of {{convert|5.22|m|ftin|abbr=on}}, and a [[draught (ship)|draught]] of {{convert|3.68|m|ftin|abbr=on}}. The submarine was powered by two six-cylinder four-stroke diesel engines each producing {{convert|250|PS|kW shp}} (a total of {{convert|500|PS|kW shp}}), two [[electric motor]]s producing {{convert|460|PS|kW shp}}, and two [[propeller shaft]]s. She had a dive time of 48 seconds and was capable of operating at a depth of {{convert|50|m}}.{{sfn|Gröner|1991|pp=31-32}}

The submarine had a maximum surface speed of {{convert|11.6|kn}} and a submerged speed of {{convert|6.6|kn}}. When submerged, she could operate for {{convert|53|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|9260|nmi}} at {{convert|7|kn}}. ''UC-27'' was fitted with six {{convert|100|cm}} mine tubes, eighteen UC 200 mines, three {{convert|50|cm}} [[torpedo tube]]s (one on the stern and two on the bow), seven torpedoes, and one [[8.8 cm SK L/30 naval gun|{{convert|8.8|cm|in|sp=us|abbr=on}} Uk L/30]] [[deck gun]]. Her [[Ship's company|complement]] was twenty-six crew members.{{sfn|Gröner|1991|pp=31-32}}
