German submarine U-714 was a Type VIIC U-boat Nazi Germany's Kriegsmarine built for service during World War II. She was laid down on 29 December 1941 by H. C. Stülcken Sohn at Hamburg and commissioned on 10 February 1943. She was commanded throughout her career by Oberleutnant zur See Hans-Joachim Schwebcke.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-714 had a displacement of {{convert|769|t|LT}} when at the surface and {{convert|871|t|LT}} while submerged.{{sfn|Gröner|1991|pp=43-46}} She had a total length of {{convert|67.10|m|ftin|abbr=on}}, a pressure hull length of {{convert|50.50|m|ftin|abbr=on}}, a beam of {{convert|6.20|m|ftin|abbr=on}}, a height of {{convert|9.60|m|ftin|abbr=on}}, and a draught of {{convert|4.74|m|ftin|abbr=on}}. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of {{convert|2800 to 3200|PS|kW shp|-1}} for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of {{convert|750|PS|kW shp}} for use while submerged. She had two shafts and two {{convert|1.23|m|ft|abbr=on|0}} propellers. The boat was capable of operating at depths of up to {{convert|230|m}}.{{sfn|Gröner|1991|pp=43-46}}

The submarine had a maximum surface speed of {{convert|17.7|kn}} and a maximum submerged speed of {{convert|7.6|kn}}.{{sfn|Gröner|1991|pp=43-46}} When submerged, the boat could operate for {{convert|80|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|8500|nmi}} at {{convert|10|kn}}. U-714 was fitted with five {{convert|53.3|cm|in|0|abbr=on}} torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and two twin 2 cm FlaK 30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.{{sfn|Gröner|1991|pp=43-46}}

Fate

She was sunk on 14 March 1945 near Eyemouth in the Firth of Forth at position {{coord|55|57|N|01|57|W|type:landmark_region:GB|display=title}} by depth charges from the South African frigate HMSAS Natal. {{HMS|Wivern|D66|6}} was granted a share of the credit for this kill as well. She had a complement of 50 crew, and when she sank, all of her crew died. She was designated as a protected place under the Protection of Military Remains Act 1986 in 2008.

=Wolfpacks=

U-714 took part in six wolfpacks, namely:

  • Körner (30 October – 2 November 1943)
  • Tirpitz 1 (2 – 8 November 1943)
  • Eisenhart 2 (9 – 15 November 1943)
  • Schill 3 (18 – 22 November 1943)
  • Weddigen (22 – 30 November 1943)
  • Igel 1 (3 – 17 February 1944)
