German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-370 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-370 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 two 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
The submarine was laid down on 25 August 1942 at the Flensburger Schiffsbau yard at Flensburg as yard number 493, launched on 28 July 1942 and commissioned on 12 November under the command of Oberleutnant zur See Karl Nielsen.
The boat's first patrol was preceded by trips from Kiel to Marviken and then back to Kiel, from where she departed on 9 July 1944. She sailed through the Baltic and into the Gulf of Finland, arriving at Reval, (now Tallinn in Estonia), on 12 July.
She spent the rest of her career in the Ostsee, sinking the Soviet Patrol boat MO-101 in Björkö Sound on 31 July 1944 during her fifth patrol.
During her ninth sortie Matrosengefreiter Erwin Stiegeler was swept overboard in the Baltic on 23 September 1944.
It was while on her eleventh foray that she sank the Finnish minelayer Louhi (12 January 1945).
