Named in honor of Graf (Count) Ferdinand von Zeppelin, the ship was launched on 8 December 1938, and was 85% complete by the outbreak of World War II in September 1939. Graf Zeppelin was not completed and was never operational due to shifting construction priorities necessitated by the war. She remained in the Baltic for the duration of the war; with Germany's defeat imminent, the ship's custodian crew scuttled her just outside Stettin in March 1945.
