is a pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the late 1890s. Named after Mount Mikasa in Nara, Japan, the ship served as the flagship of Vice Admiral Tōgō Heihachirō throughout the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war and the Battles of the Yellow Sea and Tsushima. Days after the end of the war, Mikasas magazine accidentally exploded and sank the ship. She was salvaged and her repairs took over two years to complete. Afterwards, the ship served as a coast-defence ship during World War I and supported Japanese forces during the Siberian Intervention in the Russian Civil War. After 1922, Mikasa was decommissioned in accordance with the Washington Naval Treaty and preserved as a museum ship at Yokosuka. She was badly neglected during the post-World War II Occupation of Japan and required extensive refurbishing in the late 1950s. She has been partially restored, and is now a museum ship located at Mikasa Park in Yokosuka. Mikasa is the last remaining example of a pre-dreadnought battleship anywhere in the world and also the last example of a British-built battleship. Background The combat experience of the lightly armoured Matsushima-class cruisers during the First Sino-Japanese War of 1894–1895 convinced the Imperial Japanese Navy of weaknesses in the Jeune Ecole naval philosophy, and Japan embarked on a program to modernize and expand its fleet in preparation for further confrontations. In particular, Japan promulgated a ten-year naval build-up programme, with the construction of six battleships and six armoured cruisers at its core. These ships were paid for from the £30,000,000 indemnity paid by China after losing the First Sino-Japanese War. As with the earlier and s, Japan lacked the technology and capability to construct its own battleships, and turned again to the United Kingdom for the four remaining battleships of the programme. Mikasa, the last of these ships, was ordered from the Vickers shipyard in Barrow-in-Furness in 1898 at the cost of £880,000 (8.8 million yen at that time). Although she closely resembled several of the other ships ordered in this program, she was the only ship in her class. Design and description The design of Mikasa was a modified version of the s of the Royal Navy with two additional guns. Mikasa had an overall length of , a beam of , and a normal draught of . She
