German submarineU-235 was aType VIIC U-boat ofNazi Germany'sKriegsmarine duringWorld War II.

Design

[edit]

German Type VIIC submarines were preceded by the shorterType VIIB submarines.U-235 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.^[3] She had a total length of 67.10 m (220 ft 2 in), apressure hull length of 50.50 m (165 ft 8 in), abeam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and adraught of 4.74 m (15 ft 7 in). The submarine was powered by twoGermaniawerft F46 four-stroke, six-cylindersupercharged 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, twoAEG GU 460/8–27double-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).^[3]

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).^[3] 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-235 was fitted with five 53.3 cm (21 in)torpedo tubes (four fitted at the bow and one at the stern), fourteentorpedoes, one8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had acomplement of between forty-four and sixty.^[3]

Service history

[edit]

The submarine waslaid down on 25 February 1942 at theFriedrich Krupp Germaniawerft yard atKiel as yard number 665,launched on 4 November andcommissioned on 19 December under the command ofOberleutnant zur See Goske von Möllendorf.^[2]

After training with the5th U-boat Flotilla at Kiel,U-235 was transferred to the22nd flotilla on 29 October 1943, following her sinking in May by US bombs in Kiel. She had been raised, repaired and returned to service. She was reassigned to the31st U-boat Flotilla on 2 April 1945, less than two weeks before her second sinking.

Loss

[edit]

On 14 April 1945,U-235 was heading to Norway withU-1272 when they encountered a small German convoy accompanied by the torpedo boatT17. All vessels had not been warned of the others' presence but the convoy had been warned that a British submarine was in the area.U-1272 dived deep and out of trouble, butU-235 surfaced, possibly to identify herself and then as if changing her mind, also dived.T17 attacked, droppingdepth charges. Any celebration onT17 was abruptly stilled when amongst the wreckage appearing were bodies inKriegsmarine uniform.^[1] Forty-six men died; there were no survivors.^[2]
