SM UC-73{{#tag:ref|"SM" stands for "Seiner Majestät" ({{lang-en|His Majesty's}}) and combined with the U for Unterseeboot would be translated as His Majesty's Submarine.|group=Note}} was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy ({{lang-de|Kaiserliche Marine}}) during World War I. The U-boat was ordered on 12 January 1916 and was launched on 26 August 1916. She was commissioned into the German Imperial Navy on 24 December 1916 as SM UC-73. In ten patrols UC-73 was credited with sinking 9 ships, either by torpedo or by mines laid. UC-73 was surrendered on 6 January 1919 and broken up at Brighton Ferry in 1919–20.[1]

Design

A German Type UC II submarine, UC-73 had a displacement of {{convert|427|t|LT}} when at the surface and {{convert|508|t|LT}} while submerged. She had a length overall of {{convert|50.35|m|ftin|abbr=on}}, a beam of {{convert|5.22|m|ftin|abbr=on}}, and a draught of {{convert|3.64|m|ftin|abbr=on}}. The submarine was powered by two six-cylinder four-stroke diesel engines each producing {{convert|300|PS|kW shp}} (a total of {{convert|600|PS|kW shp}}), two electric motors producing {{convert|620|PS|kW shp}}, and two propeller shafts. 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|12|kn}} and a submerged speed of {{convert|7.4|kn}}. When submerged, she could operate for {{convert|52|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|10420|nmi}} at {{convert|7|kn}}. UC-73 was fitted with six {{convert|100|cm}} mine tubes, eighteen UC 200 mines, three {{convert|50|cm}} torpedo tubes (one on the stern and two on the bow), seven torpedoes, and one {{convert|8.8|cm|in|sp=us|abbr=on}} Uk L/30 deck gun. Her complement was twenty-six crew members.{{sfn|Gröner|1991|pp=31-32}}
