start of her construction three months after her half-sisters. Despite the demanding schedule the ships suffered from a number of delays during construction. On 10 February 1914 changes were ordered by the Naval Ministry to incorporate the lessons learned from the full-scale armor trials conducted using the Chesma. This added almost of weight to the ships and raised their cost by 220,000–250,000 rubles. Other delays were incurred after the war began as imported components took longer to reach the shipyards and factories switched over to war production. The construction of Imperator Aleksander III was deliberately delayed in order to accelerate the completion of her two sisters and some of her turrets were transferred to Imperatritsa Mariya as well. Service history Imperatritsa Mariya Imperatritsa Mariya (, "Empress Maria") was launched on 19 October 1913 and arrived in Sevastopol on 13 July 1915, where she completed her fitting out during the next few months and conducted sea trials. She provided cover while the pre-dreadnought battleships conducted shore bombardment missions in October 1915. She encountered the ex-German light cruiser Midilli twice during 1916, but the cruiser escaped with nothing more than splinter damage. On 20 October 1916, she capsized and sank in Sevastopol harbor after a magazine fire and subsequent explosion. Following a complex salvage operation, she was eventually raised and placed in drydock in May 1918. However, in the chaos of the Russian Revolution and subsequent Civil War, no further repair work was done, and the ship was scrapped beginning in 1926. Her guns and their turrets, which had fallen out of the ship when she capsized, were later salvaged in 1931–1933. Two of the guns were used in the 30th Coast Defense Battery defending Sevastopol during World War II, also known as Maksim Gor'kii I by the Germans. Imperatritsa Ekaterina Velikaya Imperatritsa Ekaterina Velikaya (, "Empress Catherine the Great") was launched on 6 June 1914 and completed on 18 October 1915. She was originally named Ekaterina II until 27 June 1915 and was renamed Svobodnaya Rossiya () in 1917. She engaged the German battlecruiser SMS Goeben while the latter was in Turkish service as Yavuz Sultan Selim only once, but failed to inflict anything more severe than splinter damage. She also encountered Midilli on 16 April 1916, but the cruiser used her higher speed to escape. She was scuttled on 18 June 1918 in Novorossiysk to prevent her from being turned
