German submarine U-2545 was a Type XXI U-boat of Nazi Germany's Kriegsmarine during World War II. The Elektroboote submarine was laid down on 20 November 1944 at the Blohm & Voss yard at Hamburg, launched on 22 February 1945, and commissioned on 8 April 1945 under the command of Korvettenkapitän Otto von Bülow. With the end of the war near, training on U-boats had dropped to a minimum due to lack of fuel, falling morale and the effectiveness of allied attacks on U-boat construction and preparation. The exception to this were the new Type XXI boats, which continued to train in the Baltic Sea.
