U-1308 was the last Type VII/41 submarine to be laid down, launched and commissioned by the German Kriegsmarine during World War II. The Oberkommando der Marine or OKM, (the German naval high command), had decided near the end of World War II to put all of its resources into building newer types of Unterseeboot, such as the types XXI and XXIII. U-1308 was part of a batch of eight U-boats (U-1301 to U-1308) ordered on 1 August 1942 to be built at Flensburger Schiffbau-Gesellschaft, Flensburg (). She was laid down on 16 February 1944 and launched on 22 November. The eight boats were commissioned over a 12-month period between February 1944 and 17 January 1945 .
