U1363

U-1363 was a German submarine (U-boat) of the Kriegsmarine that served toward the end of World War II. It was a Type VIIC/41 submarine, an incremental development of the standard Type VIIC class used by the German fleet. The boat was built by Blohm & Voss in Hamburg, laid down in 1943, launched in 1944, and commissioned into service later that year.

As a late-war unit, U-1363 followed the typical duties of Type VIIC/41 boats, undergoing training before deployment. Its operational career was brief; there are no recorded sinkings attributed to U-1363, and it operated under the challenging conditions faced by German submarines during the Allied naval offensive.

With Germany's defeat in May 1945, U-1363 surrendered to Allied forces. The submarine was taken to the United Kingdom for examination. Like many surrendered U-boats, it was disposed of in the postwar period, ultimately being scuttled as part of Operation Deadlight in waters off the coast of Scotland or in the North Atlantic during 1946–1947.

U-1363 is one of the late-war U-boats that illustrate the changing nature of the Battle of the Atlantic, where improved Allied antisubmarine tactics and technology reduced the effectiveness of German submarine campaigns. The record of U-1363 contributes to the broader history of Kriegsmarine U-boat construction, deployment, and the postwar handling of German naval assets.
