The Borodino-class battleships were a group of five pre-dreadnought battleships built for the Imperial Russian Navy around the end of the 19th century. Their design was based on that of the French-built Tsesarevich modified to use Russian equipment. The first four ships were finished after the start of the Russo-Japanese War of 1904–1905 and were among the ships ordered to sail from the Baltic Sea to the Far East to relieve the Pacific Squadron besieged by the Japanese in Port Arthur. Three of these ships were sunk and one was captured by the Imperial Japanese Navy at the Battle of Tsushima in 1905. The fifth and final ship, Slava, was not completed in time to participate in the war and served with the Baltic Fleet through World War I.
