German submarine U-714

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 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-714 was fitted with five 53.3 cm 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 C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Fate
She was sunk on 14 March 1945 near Eyemouth in the Firth of Forth at position by depth charges from the South African frigate HMSAS Natal. HMS Wivern (D66) 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.
