 Preussen served in this capacity with the newly reformed Reichsmarine until 1929. She was stricken from the naval register on 5 April 1929; the Reichsmarine sold her to ship breakers on 25 February 1931 for 216,800 Reichsmarks. Preussen was subsequently broken up for scrap in Wilhelmshaven, though a 63 m (207 ft) length of her hull was retained as a testing target for underwater weapons, including torpedoes and mines. The section of hull was nicknamed "SMS Vierkant (" SMS Rectangle "). Allied bombers attacked and sank the section of Preussen's hull in April 1945. It was eventually raised and scrapped in late 1954.
