'''SM ''U-74'''''{{#tag:ref|"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''.|group=Note}} was a Type UE 1 submarine and one of the 329 [[submarine]]s serving in the [[Imperial German Navy]] in [[World War I]].
''U-74'' was engaged in the [[Naval warfare of World War I|naval warfare]] and took part in the [[First Battle of the Atlantic]].
==Design==
[[Type UE I submarine]]s were preceded by the longer [[Type U 66 submarine|Type U 66 submarines]]. ''U-74'' had a displacement of {{convert|755|t|LT}} when at the surface and {{convert|829|t|LT}} while submerged.{{sfn|Gröner|1991|pp=10–11}} She had a total length of {{convert|56.80|m|ftin|abbr=on}}, a [[pressure hull]] length of {{convert|46.66|m|ftin|abbr=on}}, a [[beam (nautical)|beam]] of {{convert|5.90|m|ftin|abbr=on}}, a height of {{convert|8.25|m|ftin|abbr=on}}, and a [[draught (ship)|draught]] of {{convert|4.84|m|ftin|abbr=on}}. The submarine was powered by two {{convert|800|PS|kW shp}} engines for use while surfaced, and two {{convert|800|PS|kW shp}} engines for use while submerged. She had two propeller shafts. She was capable of operating at depths of up to {{convert|50|m}}.{{sfn|Gröner|1991|pp=10–11}}
The submarine had a maximum surface speed of {{convert|10.6|kn}} and a maximum submerged speed of {{convert|7.9|kn}}.{{sfn|Gröner|1991|pp=10–11}} When submerged, she could operate for {{convert|83|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|5480|nmi}} at {{convert|7|kn}}. ''U-74'' was fitted with two {{convert|50|cm}} [[torpedo tube]]s (one at the port bow and one starboard stern), four torpedoes, and one [[8.8&nbsp;cm SK L/30 naval gun|{{convert|8.8|cm|in|sp=us|abbr=on}} SK L/30]] [[deck gun]]. She had a [[Ship's company|complement]] of thirty-two (twenty-eight crew members and four officers).{{sfn|Gröner|1991|pp=10–11}}
