German submarine U-2322 was a highly advanced Type XXIII U-boat built for Nazi Germany's Kriegsmarine in 1944.

When she was finally ready for a war patrol in February 1945, it was more as an experiment into the abilities of the boat than a real attempt to damage allied shipping.

Leaving Horten Naval Base in Norway on the 6 February 1945, U-2322 proceeded to the East coast of Scotland, particularly in the area of St Abb's Head, where lone coastal shipping sometimes passed, believing that German U-boats would not bother waiting in such a dangerous spot for such insignificant prey.

The second patrol, off East Anglia in April was totally fruitless, powerful allied escorts and well-organised convoys effectively cutting off the small U-boats from their potential targets.

The only advantage gained in these patrols was that no Type XXIII boat was lost in the North Sea, all losses coming in German waters from indirect sources like accident, bombing raids and naval mines.
