Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-388 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-388 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and two twin 2 cm C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history
U-388 conducted her training as part of the 5th U-boat Flotilla, before being attached to the 9th U-boat Flotilla for front-line service on 1 June 1943.

U-388 sailed from Kiel on 8 June 1943 on her first patrol in the Atlantic. On 20 June, she was sunk south-east of Cape Farewell, Greenland, in position 57.6°N, -31.33333°W, by depth charges from a PBY Catalina aircraft of United States Navy Patrol Squadron VP-84, and was lost with all 47 men on board.
