German submarine U-1022 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine. She was laid down on 6 May 1943 by Blohm & Voss in Hamburg, Germany, and commissioned on 7 June 1944, the day after the Allied landings in Normandy, with Kapitänleutnant Hans-Joachim Ernst in command. She sank two ships for a total of 1,720 metric tonnes. After the war she was handed over to the Allies and sunk in Operation Deadlight.

U-1022 was ordered by the Kriegsmarine on 13 June 1942. She was laid down less than one year later at Blohm & Voss, Hamburg on 6 May 1943 . U-1022 was launched from Hamburg on 13 April 1944. She was formally commissioned later that year on 7 June 1944, the day after the Allied landings at Normandy. U-1022 carried 5 × 53.3 cm (21 in) torpedo tubes (4 located in the bow, 1 in the stern) and had one 8.8 cm (3.46 in) deck gun with 220 rounds. She could also carry 14 G7e torpedoes or 26 TMA mines and had a crew of 44-52 men.[1]

Service History[edit]

After her training (during which she travelled from Germany to Norway), U-1022 left her home port of Bergen, Norway on her first and only patrol.[2] During this patrol, which lasted 49 days, U-1022 traveled from Norway to the southern coast of Iceland. In this time span she managed to sink two enemy vessels, the Panamanian steam merchant Alcedo for a loss of 1,392 tonnes and the British vessel, HMS Southern Flower for a loss of 328 tonnes. U-1022 arrived back in Bergen on 1 April 1945 and remained in port for the remainder of the war. Following Germany's defeat in the war, U-1022 along with most of the remaining German submarine fleet were sunk in Operation Deadlight.[1]
