Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-988 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] 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 Brown, Boveri & Cie GG UB 720/8 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).[2]

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).[2] 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-988 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 one twin 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]

Service history

U-988′s career began on 15 July 1943 with training as part of the 5th U-boat Flotilla. On 8 September 1943, she collided with U-983 in the Baltic Sea north of Loba (54°46′N 17°14′E / 54.767°N 17.233°E / 54.767; 17.233). As a result of the collision, U-983 sank with the loss of five of her 43 crew.[3]

U-988 began active service on 1 June 1944 as part of the 7th U-boat Flotilla.

Wolfpacks

U-988 took part in no wolfpacks.

Fate

U-988 was sunk by depth charges from a US Liberator on 22 June 1944. All hands lost after the attack.[4]

Previously recorded fate

U-988 sent her last radio message on 18 June, informing about an air attack, and was lost with all hands thereafter, and her fate is not certain.[5] It is believed, that U-988 attacked three ships in 27–29 June and then was sunk on 29/30 June 1944 in the English Channel west of Guernsey at 49°37′N 03°41′W / 49.617°N 3.683°W / 49.617; -3.683 at dawn by the Royal Navy frigates HMS Essington, HMS Cooke, HMS Duckworth, and HMS Domett, after being damaged by and Royal Air Force Liberators of No. 244 Squadron.[6]

Alternate fate

There appeared however a theory, that U-988 could have been sunk after an attack of Polish Wellington Mk XIV from 304 Squadron, piloted by Leopold Antoniewicz, which was credited with sinking a submarine on 18 June in the approximate position 49°03′N 04°48′W / 49.050°N 4.800°W / 49.050; -4.800.[5] Then, the submarine sank on 29/30 June could have been U-1191.[5]
