The U-boat's service began with training as part of the 4th U-boat Flotilla. She then moved to the 10th flotilla on 1 September 1942 for operations. She sank two ships, totalling 8,396 gross register tons (GRT), one auxiliary warship of 358 GRT and damaged three others, for 14,499 GRT. She also damaged one auxiliary warship (7,252 GRT).
An RAF aircraft with a Czechoslovak crew sank her on 27 September 1942.
Design
editGerman Type IXC submarines were slightly larger than the original Type IXBs. U-165 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged.[1] The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[1]
The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).[1] When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,450 nautical miles (24,910 km; 15,480 mi) at 10 knots (19 km/h; 12 mph). U-165 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) SK C/30 as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.[1]
Service history
editPatrol
editThe submarine's only patrol took her from Kiel on 7 August 1942, across the North Sea and into the northern Atlantic Ocean via through the gap between Iceland and the Faroe Islands to the Gulf of the St. Lawrence.
Her first victims were USS Laramie and Arlyn; both damaged during an attack on convoy SG-6 at the northern end of the Belle Isle Strait on 28 August. One of the ships was then finished off by U-517.
On 6 September U-165 found convoy QS-33 and during several attacks sank the freighter Aeas and the escort HMCS Raccoon.
On 15 September U-517 attacks convoy SQ-36, and signals U-165 which can attack the next day. U-165 can sink one ship out of the convoy and damage two more ships.
Loss
editU-165 had almost reached the French Atlantic ports when on 27 September 1942 an RAF Coastal Command Vickers Wellington 1C on patrol from RAF Talbenny found her on the surface just west of the Bay of Biscay. The Wellington, with serial number Z1147 and code letters KX-Q, belonged to No. 311 Squadron RAF, whose aircrew were Czechoslovaks.[4]
The pilot, Plt Off Václav Študent, attacked at an altitude of 70 feet (21 m). His navigator and bomb aimer, Flt Lt Václav Kadaně, aimed six depth charges at U-165. Their explosions lifted the U-boat out of the water, but she managed to submerge to escape further attack.[4]
Shrapnel wounded three of the Wellington's crew, including the co-pilot, and a fourth crew member lost a finger. The machine gun fire also damaged the aircraft's hydraulic equipment. Študent broke off the attack, and at 19:58 hrs crash-landed the Wellington at St Eval, Cornwall. Two of the wounded Czechoslovak crew were hospitalised. However, the attack succeeded in sinking U-165.[4]
In older sources, the U-165 is listed as being lost to unknown causes, or to have run on a mine.[3][2]
