She was ordered on 5 June 1941, and was laid down on 8 February 1943 at Friedrich Krupp Germaniawerft AG, Kiel, as yard number 686. She was launched on 16 December 1943 and commissioned under the command of Oberleutnant zur See Friedrich Weidner on 20 January 1944.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-1052 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 460/8-276 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-1052 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), one 3.7 cm (1.5 in) Flak M42 and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between 44 — 52 men.
On 9 May 1945, U-1052 surrendered at Bergen, Norway. She was later transferred to Loch Ryan, Scotland on 30 May 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1052 was one of 116 selected to take part in Operation Deadlight. U-1052 was towed out on 9 December 1945, and sunk by aircraft of the RN's 816 Squadron.
The wreck is located at 55°50′N 10°05′W.
