German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-595 had a displacement of 769t when at the surface and 871t while submerged. She had a total length of 67.1m (220.1feet), a pressure hull length of 50.5m (165.7feet), a beam of 6.2m (20.3feet), a height of 9.6m (31.5feet), and a draught of 4.74m (15.55feet). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of NaNPS for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of 750PS for use while submerged. She had two shafts and two 1.23abbr=onNaNabbr=on propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-595 was fitted with five 53.30NaN0 torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.82NaN2 SK C/35 naval gun, 220 rounds, and a 2sp=usNaNsp=us C/30 anti-aircraft gun.

The boat's career began with training at 8th U-boat Flotilla on 6 November 1941, followed by active service on 1 August 1942 as part of the 9th Flotilla for the remainder of her service.
In three patrols she sank no ships.
U-595 was sunk on 14 November 1942 in the Mediterranean in position 36.6333°N 30°W, by depth charges from two RAF Hudson bombers from 608 Squadron. The depth charges damaged her so badly that she had to surface, and the commander took the decision to beach her on the Algerian coast near Ténès. During the air attack the crew were able to damage some aircraft with machine-gun fire. There were 45 survivors and no casualties.
U-595 took part in five wolfpacks, namely:
