German submarine U-2323

German submarine U-2323 was a Type XXIII submarine of Nazi Germany's Kriegsmarine during World War II. She was constructed at Hamburg during the spring of 1944, completed on the 18 July and given to Leutnant zur See Walter Angermann to command. A fast high-technology coastal boat, U-2323 was expected to be the new war-winning weapon in the Kriegsmarine arsenal.

Design
Like all Type XXIII U-boats, U-2323 had a displacement of 234 t when at the surface and 258 t while submerged. She had a total length of 34.68 m (o/a), a beam width of 3.02 m (o/a), and a draught depth of3.66 m. The submarine was powered by one MWM six-cylinder RS134S diesel engine providing 575 - 630 PS, one AEG GU4463-8 double-acting electric motor electric motor providing 580 PS, and one BBC silent running CCR188 electric motor providing 35 PS.

The submarine had a maximum surface speed of 9.7 kn and a submerged speed of 12.5 kn. When submerged, the boat could operate at 4 kn for 194 nmi; when surfaced, she could travel 2600 nmi at 8 kn. U-2323 was fitted with two 53.3 cm torpedo tubes in the bow. She could carry two preloaded torpedoes. The complement was 14–18 men. This class of U-boat did not carry a deck gun.

Service history
The seas around the German coastline were subject to very heavy allied attack during the final two years of the war, as the Royal Air Force sought to restrict German movement around their coasts by sowing thousands of air-dropped naval mines, thus delaying the production and training of new boats, disrupting coastal shipping and destroying several boats before they could become involved in the Battle of the Atlantic.

The U-2323 was a victim of this campaign, when on the 26 July 1944, just eight days old, she was sunk off Möltenort at the entrance to Kiel harbour on her maiden voyage. Two of her crew were killed in the blast, although the survivors managed to safely reach the shore. They were then transferred to other units. The holed boat was raised in early 1945, but was still undergoing repairs in Kiel at the time of the German surrender. It was broken up in situ post-war.
