After the self-sinking, the demolition squad was picked up by a German mine clearance boat and taken to Varna in Bulgaria . The clearing boat reached Varna at around 2:00 a.m. and met the rest of the boat's crew, who had been transferred from Constanța on a naval ferry .
U 24 was lifted by the Soviet Black Sea Fleet's emergency service in the spring of 1945 and transferred to Sevastopol for restoration . However, the restoration failed due to irreparable damage. The boat was nevertheless preserved from June 7, 1945 for longer storage and added to the list of the Black Sea Fleet.
