German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-418 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 Siemens-Schuckert GU 343/38–8 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-418 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 sixty.
The submarine was laid down on 21 October 1941 at the Danziger Werft (yard) at Danzig (now Gdansk), as yard number 119, launched on 11 July 1942 and commissioned on 21 October under the command of Oberleutnant zur See Gerhard Lange.
Patrol and loss
U-418 left Kiel on 24 April 1943 and headed for the Atlantic Ocean via the gap between Iceland and the Faroe Islands. The boat was attacked, (but it was not reported), by a British Catalina flying boat of No. 210 Squadron RAF on 30 May. One man was killed, two others were wounded. The aircraft sank on its return to Pembroke Dock, but was later salvaged.
U-418 took part in three wolfpacks, namely.
