German submarine U-879 was a Type IXC/40 U-boat built for Nazi Germany's Kriegsmarine during World War II.

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-879 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 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 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 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 shaft horsepower (1,010 PS; 750 kW) 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 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-879 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) Flak M42 as well as two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of forty-eight.[1]

Service history

U-879 was ordered in April 1942 from DeSchiMAG AG Weser in Bremen under the yard number 1087. Her keel was laid down on 16 June 1942 and the U-boat was launched the following year on 11 January 1944. She was commissioned into service under the command of Kapitänleutnant Erwin Manchen (Crew 36) in 4th U-boat Flotilla.

U-879 was transferred to 33rd U-boat Flotilla after completing training and work up for deployment. She left her base in Horten Naval Base on 9 February 1945 for operations off the US east coast. Since another U-boat, U-857 was operating at the same time in the vicinity, it is not clear, which ships were attacked U-879 or the other U-boat, which is missing. The US tanker Atlantic States was probably hit and damaged on 5 April 1945, while the Belgian steamer Belgian Airman and the US tanker Swiftscout may have been sunk by U-879 on 14 and 18 April respectively. The Norwegian tanker Katy might have been hit and damaged on 23 April.[2]

Late on 29 April a U-boat was picked up by escorts of convoy KN 382. USS Natchez tried to ram her but missed. Natchez with three more escorts, USS Coffmann, USS Thomas, and USS Bostwick, chased the contact for several hours with depth charges and hedgehog (weapon) projectiles. In the early hours of 30 April, a strong explosion was heard and the contact disappeared. Only in 1968 a wreck was discovered, confirming the sinking of an U-boat. It is assumed that the U-boat in question was U-879, but there are indicators that it might have been U-857 instead.[3]
