German submarine U-719

German submarine U-719 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 3 July 1942 at the H. C. Stülcken Sohn yard at Hamburg, launched on 28 April 1943, and commissioned on 27 July 1943 under the command of Oberleutnant zur See Klaus-Dietrich Steffens. Attached to 5th U-boat Flotilla based at Kiel, U-719 completed her training period on 30 April 1944 and was assigned to front-line service.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-719 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-719 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.

Service history
On the first and only war patrol, U-719 was picked up by HMS Bulldog's ASDIC on 26 June 1944 northwest of Ireland. Bulldog attacked the U-boat with hedgehogs, destroying U-719 in the third attempt. All 52 crew members perished in the event.
