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

U-88 left Narvik on 25 August 1942 for her final patrol. She was sunk south of Spitzbergen at Coordinates: by depth charges from the British destroyer HMS Faulknor on 12 September. Forty-six men died; there were no survivors.
U-88 took part in three wolfpacks, namely.
- Strauchritter (29 April - 2 May 1942)
- Eisteufel (21 June - 11 July 1942)
- Trägertod (12 September 1942)
