She was launched on 21 July 1944, and commissioned under the command of Oberleutnant zur See Joachim-Werner Bach on 24 September 1944.

The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two SSW GU 343/38-8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged.

Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1110 was one of 116 selected to take part in Operation Deadlight.
