German submarine U-88 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Contents

She was laid down at the Flender Werke in Lübeck as yard number 292, launched on 16 August 1941 and commissioned on 15 October with Kapitänleutnant Heino Bohmann in command.

She was a fairly successful boat, succeeding in sinking over 12,000 tons of Allied shipping in a career lasting just one year over three patrols.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-88 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 MAN M 6 V 40/46 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).

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-88 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.

1st patrol

Having moved from Kiel to Kirkenes in Norway in April 1942, U-88 departed for her first patrol on the 29th. She returned on 3 May.

2nd patrol

The boat moved from Kirkenes to Narvik in early May and set-off for hersecond patrol on 17 June 1942. She sank two American ships, part of the ill-fated Convoy PQ-17, on 5 July. After a three-hour pursuit, the Carlton was hit by a torpedo which did not detonate. A second torpedo exploded on impact, the ship sank in ten minutes. U-88 then hit the Daniel Morgan which had already been attacked by German aircraft. Three men died, there were 51 survivors.

3rd patrol and loss

U-88 left Narvik on 25 August 1942 for her final patrol. She was sunk south of Spitzbergen at 75°04′N 04°49′E by depth charges from the British destroyer HMS Faulknor on 12 September. Forty-six men died; there were no survivors.

Wolfpacks

U-88 took part in three wolfpacks, namely.

  • Strauchritter (29 April - 2 May 1942)
  • Eisteufel (21 June - 11 July 1942)
  • Trägertod (12 September 1942)
