German submarine U-79 was a Type VIIC U-boat of the Kriegsmarine built by the Bremer Vulkan-Vegesacker Werft, Bremen-Vegesack. Her keel was laid down on 17 April 1940, by Bremer Vulkan of Bremen-Vegesack, Germany as yard number 7. She was launched on 25 January 1941 and commissioned on 13 March, with Kapitänleutnant Wolfgang Kaufmann in command until the U-boat's loss.^[2]

The boat was sunk on 23 December 1941 north of Sollum, by two British warships.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-79 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), 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 MAN 6-cylinder 4-stroke M 6 V 40/46 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 Brown, Boveri & Cie GG UB 720/8 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).^[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-79 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 a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.^[3]

Service history

U-79 conducted three patrols whilst serving with 1st U-boat Flotilla from 13 March 1941 to 30 September. She was then reassigned to the 23rd U-boat Flotilla from 1 October until she was sunk.

First patrol

The boat's first patrol began with her departure from Kiel on 5 June 1941. Her route took her north 'up' the North Sea and through the gap separating Iceland and the Faroe Islands toward the Atlantic Ocean.

She sank the Havtor west of Iceland on the 11th and damaged the Tibia at 59°55′N 39°00′W / 59.917°N 39.000°W / 59.917; -39.000 (southwest of the island), on the 27th.

U-79 then docked at the newly captured port of Lorient on the French Atlantic coast on 5 July.

Second and third patrols

The boat's second foray was further south than her first. She was with a group of seven other U-boats that attacked Convoy OG 69 and sank the British freighter Kellwyn about 350 nmi (650 km; 400 mi) northwest of Cape Finisterre in Spain on 27 July 1941.

She was unsuccessfully attacked with depth charges by convoy escorts near the Portuguese coast on 12 August.

U-79's third sortie hardly left the Bay of Biscay and only lasted five days (14–18 September 1941).

Fourth and fifth patrols

Patrol number four necessitated the boat getting past the heavily defended British base at Gibraltar to reach the Mediterranean Sea which she had by 5 October 1941. She then negotiated the Straits of Messina [between Sicily and the Italian mainland] and moved toward the North African coast. There she encountered the British gunboat HMS Gnat and sank her 30 nmi (56 km; 35 mi) northeast of Bardia (Al Burdi) on 21 October. She reached Salamis in Greece on 23 October 1941. However HMS Gnat was salved and returned to serve as a gun platform.

U-79 returned to the North African coast for her fifth patrol at the end of November but her luck had deserted her. She returned to Salamis with nothing to show for her efforts on 8 December.

Sixth patrol and loss

Leaving Salamis for the last time on 21 December 1941, she was sunk a couple of days later (on the 23rd), by depth charges dropped by the British destroyers HMS Hasty and Hotspur in position 32°15′N 25°19′E / 32.250°N 25.317°E / 32.250; 25.317. All U-79's crewmembers (44 men) survived the attack.^[1]

Wolfpacks

U-79 took part in one wolfpack, namely:

Goeben (28 September – 5 October 1941)
