The submarine was laid down on 24 February 1942 at the Bremer Vulkan yard at Bremen-Vegesack as yard number 41. She was launched on 24 October and commissioned on 9 December under the command of Oberleutnant zur See Jürgen Thimme.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-276 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. 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 Germaniawerft F46 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 AEG GU 460/8–27 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).
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). 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-276 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 an anti-aircraft gun. The boat had a complement of between forty-four and sixty.
U-276 served with the 8th U-boat Flotilla for training from December 1942 to February 1944 and operationally with the 1st U-boat Flotilla from 1 March 1944. She was then reassigned to the 31st U-boat Flotilla on 1 July. She carried out three patrols, but sank no ships.
She was 'stricken' in September 1944 at Neustadt and used as a floating electrical generating plant. She was scuttled in May 1945.
The boat departed Trondheim on 22 March 1944 and returned to the Norwegian port fifteen days later on 6 April.
Her second sortie was relatively uneventful, apart from two crew members being wounded in an accident with the anti-aircraft gun.
By now the boat was based at Stavanger, from where she departed on 8 June 1944. She returned there on the 25th.
The submarine sailed back to Kiel in July 1944.
The boat was 'stricken' at Neustadt on 29 September 1944 and re-employed as a floating electrical generator. On 3 May 1945, the U-boat was damaged in a rocket attack by four Hawker Typhoons of No. 175 Squadron RAF. As a result of the damage, she was scuttled later that same day.
