 Hannover was brought back to active service in the Reichsmarine, the post-war Germany navy. She served with the fleet for ten years, from 1921 to 1931, before she was again decommissioned. The navy planned to convert the ship into a radio-controlled target ship for aircraft, but this was never carried out. The ship was ultimately broken up for scrap between 1944 and 1946 in Bremerhaven. Her bell is preserved at the Military History Museum of the Bundeswehr in Dresden.
