Lützow was a heavy cruiser of Nazi Germany's Kriegsmarine, the fifth and final member of the Admiral Hipper class, but was never completed.
The vessel was still incomplete when sold to the Soviet Union, with only half of her main battery of eight 20.3 cm (8 in) guns installed and much of the superstructure missing.
The Admiral Hipper class of heavy cruisers was ordered in the context of German naval rearmament after the Nazi Party came to power in 1933 and repudiated the disarmament clauses of the Treaty of Versailles.
The ship also would have carried a pair of triple 53.3 cm (21 in) torpedo launchers abreast of the rear superstructure.
The Kriegsmarine denied the request for Seydlitz and Prinz Eugen, but agreed to sell Lützow, as well as 38 cm (15 in) gun turrets and other weaponry.
[3] Complete technical specifications, the results of engine trials, and spare parts were included in the sale.
Her main battery guns had been transferred to the German army and placed on railway mountings; they had to be dismantled and returned to Bremen.
[9] The two navies agreed that Germany would be responsible for naval escort, which included destroyers and smaller vessels.
[11] Feige then led an advisory commission assigned to assist the Soviet effort to complete the ship.
[7] At the time the ship arrived in Leningrad, only the two forward gun turrets had been installed and the bridge superstructure was incomplete.
Several other ships, including the cruiser Maxim Gorky, joined Petropavlovsk in shelling the advancing Germans.
[6] Renamed Tallinn in 1943, the ship returned to service to support the Soviet counter-offensive to relieve the Siege of Leningrad in 1944.
The date of her disposal is uncertain; Erich Gröner reports the ship survived until being broken up for scrap in 1960.
