German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-417 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-417 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 twin 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 16 September 1941 at the Danziger Werft (yard) at Danzig (now Gdansk), as yard number 118, launched on 6 September 1942 and commissioned on the 26th under the command of Oberleutnant zur See Wolfgang Schreiner.
Patrol and loss
Forty-six men were lost with U-417; there were no survivors.
U-417's anti-aircraft fire had been accurate. The B-17 ditched; all eight of the crew were forced to share a single dinghy. On 14 June, an American navy PBY Catalina attempted a landing but crashed. Its crew of nine found themselves adrift on two rafts. The B-17 crew were found and rescued by Jack Holmes in a British Catalina of 190 squadron on the same day of their ditching, but the Americans were not found for another five days. Only one man survived, the others died of exposure.
