She was ordered on 5 June 1941, and was laid down on 26 June 1942 at Blohm & Voss, Hamburg, as yard number 174. She was launched on 11 March 1943 and commissioned under the command of Oberleutnant zur See Joachim Zaubitzer on 22 April 1943.
Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-974 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 Garbe, Lahmeyer & Co. RP 137/c 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-974 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA mines, 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 44 — 52 men.
Service history
On 19 June 1944, U-974 was sunk by torpedoes near Stavanger, Norway, in the Boknafjord. U-974 was attacked by a Norwegian submarine, Ula. Eight of the crew of fifty survived.
The wreck is located at 59°08′N 05°23′E.
Discovery of wreck
In 1996, an ROV at a depth of about 190 m (620 ft) discovered the wreck of U-974. She had broken into two separate parts of about 15 m (49 ft) and 40 m (130 ft) in length. The wreck of U-974 lies around 1,000 m (3,300 ft) southeast of Løten.
