German submarine U-236 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Contents

The submarine was laid down on 23 March 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 666, launched on 24 November and commissioned on 9 January 1943 under the command of Oberleutnant zur See Reimar Ziesmer. [1]

After training with the 5th U-boat Flotilla at Kiel, she spent the rest of the war as a 'school' boat. U-236 was transferred to the 24th flotilla on 29 September 1943, the 21st flotilla on 1 May 1944 and the 31st flotilla on 1 March 1945. She was scuttled near Schleimünde on 5 May 1945.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-236 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. [2] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8-276 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft). [2]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). [2] When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-236 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had a complement of between forty-four and sixty. [2]

She was the first Type VII submarine to experiment with a schnorchel in September 1943. [3]
