German submarine U-1013

German submarine U-1013 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She was ordered on 23 March 1942, and was laid down on 26 March 1943, at Blohm & Voss, Hamburg, as yard number 213. She was launched on 19 January 1944, and commissioned under the command of Oberleutnant zur See Gerhard Linck on 2 March 1944.

Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1013 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, an overall 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 BBC GG UB 720/8 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-1013 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA or TMB Naval mines, one 8.8 cm SK C/35 naval gun, (220 rounds), one 3.7 cm Flak M42 and two 2 cm C/30 anti-aircraft guns. The boat had a complement of between forty-four and fifty-two.

Service history
U-1013 participated in no war patrols.

U-1013 collided with GS U-286 and sunk on 17 March 1944, in the Baltic Sea near 54.35°N, 13.91667°W, after only 15 days in service. Her commander, Oberleutnant zur See Gerhard Linck, and 24 other men died with 26 surviving.

On 16 July 1944, U-1013 was raised and taken to Sassnitz. She was decommissioned there and probably broken up.
