She was a fairly successful boat, sinking over 13,815 GRT of Allied shipping in a career lasting just one year and five patrols. She was a member of tenwolfpacks. After training with the8th U-boat Flotilla,U-89 was assigned to the9th flotilla on 1 May 1942 for operations.
German Type VIIC submarines were preceded by the shorterType VIIB submarines.U-89 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] 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-cylindersuperchargeddiesel 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).[1]
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).[1] 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-89 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 a2 cm (0.79 in) C/30 anti-aircraft gun. The boat had acomplement of between forty-four and sixty.[1]
U-89 departedKiel for her first patrol on 14 May 1942. She docked inBrest, on the French Atlantic coast, on the 27th.
The boat's second foray started from Brest on 6 June 1942 and finishing there on 21 August. Using herdeck gun she sank a Canadian fishing boat, theLucille M., with 20 incendiary and 15 high explosive rounds offCape Sable on 25 July
U-89 sank the British ship, theJeypore on 3 November 1942 and theDaleby also British, both east ofCape Farewell (Greenland), the following day. On the fifth, she was attacked by aB-24 Liberator ofNo. 120 Squadron RAF. Originally thought to have sunkU-132,U-89 was severely damaged.
Sortie number four began from Brest on 24 January 1943; it was relatively uneventful but terminated inLa Pallice on 28 March.
U-89 left France for the last time on 25 April 1943. On 7 May she sank the GreekLaconikis northeast of theAzores but was herself sunk by a combination of aFairey Swordfish of811 Naval Air Squadron from theescort carrierHMS Biter, thedestroyerHMS Broadway and thefrigateHMS Lagan.U-89 was sunk at position46°30′N25°40′W / 46.500°N 25.667°W /46.500; -25.667.[2]
