German submarine U-1102 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.^[1]

Construction

The U-1102 was laid down on 16 April 1943 at the Nordseewerke shipyard in Emden, Germany. She was launched on 15 January 1944 and commissioned on 22 February 1944 under the command of Oberleutnant zur See Bernhard Schwarting.^[2]

Diagram of a Type VIIC U-boat.

When she was completed, the submarine was 67.10 metres (220 ft 2 in) long, with a beam of 6.18 metres (20 ft 3 in), a height of 9.60 metres (31 ft 6 in) and a draft of 4.74 metres (15 ft 7 in). She was assessed at 864.7 t (851 long tons) submerged. 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 and 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. She had two shafts and two 1.23 m (4 ft) propellers. The submarine was capable of operating at depths of up to 230 metres (750 ft), had a maximum surface speed of 17.6 knots (32.6 km/h; 20.3 mph) and a maximum submerged speed of 7.5 knots (13.9 km/h; 8.6 mph).When submerged, the U-boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph) and when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph).^[3]

The submarine was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) deck gun (220 rounds) and an 3.7 cm (1.46 in) anti-aircraft gun. The boat had a complement of 44 to 57 men.^[3]

Service history And Accident

U-1102 was used as a Training ship in the 8th U-boat Flotilla from 22 February 1944 to 12 May 1944. On 24 March 1944, the U-boat sank during a diving accident at the U-boat base quay in Pillau. Two crew members were lost in the incident and U-1102 was raised and decommissioned on 12 May 1944. She was brought to Danzig for repairs and returned to service as a school boat on 15 August 1944 under the command of a new commander Oberleutnant zur See Erwin Sell.^[2]

Capture And End

U-1102 surrendered on 13 May 1945 in the Hohwacht Bay, Germany to the Allied Forces. The submarine was transferred to Wilhelmshaven via Kiel and was transferred to Loch Ryan on 23 June 1945. She stayed in Loch Ryan for her immersion in Operation Deadlight (post-war Allied operation) until 21 December 1945, when she was towed to sea by the British destroyer HMS Zetland (L.59).^[1]

The U-2377 taken to sea to be scuttled during Operation Deadlight, the same fate was waiting for U-1102.

U-1102 was sunk at 15:05 on 21 December 1945 in the North Atlantic, North-West off the coast of Ireland by naval gun fire from the Polish destroyer ORP Piorun (G.65), the British destroyers HMS Onslaught (G.04) and HMS Zetland (L.59) and the British sloop HMS Fowey (L.15) sunk.^[2]
