Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1305 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 AEG GU 460/8-276 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-1305 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
On 10 May 1945, U-1305 surrendered at Loch Eriboll, Scotland. She was later transferred to Loch Ryan, Scotland on 30 May 1945.
Post war service
The TNC allocated U-1305 to the Soviet Union. On 4 December 1945, she arrived in Libau, Latvia, as British N-class N25. On 13 February 1946, the Soviet Navy allocated her to the Baltic Fleet. She was renamed S-84 on 9 June 1949 then sent to the reserve fleet on 30 December 1955. S-84 went to the Northern Fleet as a test hulk and was later sunk in the Barents Sea on 10 October 1957, during an atomic bomb test off of Novaja Zemlja.
The wreck now lies approximately at 70.703°N 54.6°E / 70.703; 54.6.
