She was ordered on 2 April 1942, and was laid down on 20 April 1943 at Neptun Werft AG, Rostock, as yard number 517. She was commissioned under the command of Oberleutnant zur See Werner Schulz on 6 December 1944.
Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-930 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), an overall 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 BBC 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).
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-930 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 fifty-two.
Service history
U-930 did not participate in any war patrols before surrendering at Bergen, Norway, on 9 May 1945.
On 30 May 1945, U-930 was transferred to Lisahally where she would wait nearly seven months for her final fate. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-930 was one of 116 selected to take part in Operation Deadlight. U-930 was towed to 55°20′N 07°35′W on 29 December 1945, and sunk by the British destroyer Onslow.
