The U-boat had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of for use while submerged. She had two shafts and two 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-526 was fitted with six torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one SK C/32 naval gun, 180 rounds, and a SK C/30 as well as a C/30 anti-aircraft gun.

U-526 was laid down at Deutsche Werft's Hamburg shipyard on 14 October 1941, as Yard number 341. She was launched on 3 June 1942 and commissioned on 12 August 1942.
Service history Following commissioning, U-526, under the command of Kapitänleutnant Hans Möglich, joined the 4th U-boat Flotilla based at Stettin, for training. Patrol and loss The submarine's only patrol was preceded by short passages from Kiel in Germany to Kristiansand then Bergen in Norway over January 1943. She joined the operational 10th U-boat Flotilla on 1 February 1943, and left Bergen on 11 February 1943 bound for the North Atlantic, crossing the North Sea and passing into the Atlantic Ocean through the 'gap' between Iceland and the Faroe Islands. U-526 was ordered to join the patrol group Burggraf, which formed on 26 February north of the Azores and swept westward, joining up with group Wildfang east of Newfoundland. After Convoy SC 121 was spotted by on 6 March, U-526 was one of 17 U-boats directed to form group Westmark and attack SC 121. The Westmark U-boats attacked the convoy in a heavy storm on 7–8 March, sinking eight merchant ships. On 14 March U-526 joined group Stürmer, south of Iceland, which from 16 March took part in attacks against Convoys HX 229 and SC 122. While 21 allied ships were sunk for the loss of 1 U-boat in what has been described as the largest convoy battle of the war, U-526 had no success, as problems with her engines forced her to break off pursuit of the convoy. On 24 March U-526 joined group Seeteufel as it attempted to intercept Convoys ONS 1 and HX 230, but had no success, and in early April set course for her new base of Lorient, refuelling from the tanker submarine .
After crossing the Bay of Biscay, U-526 rendezvoused with the submarine and a minesweeper escort outside Lorient on 14 April 1943. At from the port, the minesweeper escort turned away and U-526 moved ahead of U-513, before striking a British mine. U-526 was blown in two, with 42 men killed, including Möglich, with 12 survivors, 9 of whom were injured. Two of the survivors were picked up by U-513, with three rescued from the sunken submarine at a depth of by divers. The wreck of U-513 was later raised and her engines salvaged.
