Design
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1106 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 SSW GU 343/38-8 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-1106 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, and an anti-aircraft gun. The boat had a complement of between forty-four and fifty-two.

Service history
On 29 March 1945, nine days out of Horten, on her first, and only, war patrol, she was located by a British Liberator aircraft of the 224 Squadron RAF/O. U-1106 was sunk by depth charges in the Norwegian Sea, north of the Shetland Islands, with all 46 of her crew.

The wreck now lies at 61.76667°N, -2.26667°W.
