Japanese battleship Fuji Design and description . " Fuji " was long overall and had a beam of and a full - load draught of . She normally displaced and had a crew of 637 officers and enlisted men . The ship was powered by two Humphrys Tennant vertical triple - expansion steam engines using steam generated by ten cylindrical boilers . The engines were rated at , using forced draught , and designed to reach a top speed of around . " Fuji " , however , reached a top speed of on her sea trials . She carried a maximum of of coal which allowed her to steam for at a speed of . The ship ' s main battery consisted of four guns mounted in two twin gun turret s , one forward and one aft . The secondary battery consisted of ten quick - firing gun s , four mounted in casemate s on the sides of the hull and six mounted on the upper deck , protected by gun shield s . A number of smaller guns were carried for defence against torpedo boat s . These included fourteen 3 - pounder guns and ten 2 . 5 - pounder Hotchkiss gun s of the same calibre . She was also armed with five 18 - inch torpedo tube s . " Fuji " s waterline armour belt consisted of Harvey armour and was thick . The armour of her gun turrets was six inches thick and her deck was thick . Construction and career . " Fuji " , named after Mount Fuji , was ordered as part of the 1894 Naval Programme and the ship was laid down by Thames Iron Works at their Blackwall , London shipyard on 1 August 1894 . The ship was launched on 31 March 1896 and completed on 17 August 1897 . The work was supervised by a team of over 240 engineers and naval officers from Japan , including future Prime Ministers Saitō Makoto and Katō Tomosaburō . While fitting out at Portland , she participated in the fleet review marking Queen Victoria ' s Diamond Jubilee on 26 June 1897 at Spithead before departing for Japan via the Suez Canal . In 1901 , the ship exchanged 16 of her 47 mm guns for an equal number of QF 12 pounder 12 cwt guns . This raised the number of crewmen to 652 and later to 741 . At the start of the Russo - Japanese War , " Fuji " , commanded by Captain Kazu Matsumoto , was assigned to the 1st Division of the 1st Fleet . She participated in the Battle of Port Arthur on 9 February 1904 when Admiral Tōgō Heihachirō led the 1st Fleet in an attack on the Russian ships of the Pacific Squadron anchored just outside of Port Arthur . Tōgō had expected his surprise night attack on the Russians by his destroyers to be much more successful than it actually was and expected to find them badly disorganized and weakened , but the Russians had recovered from their surprise and were ready for his attack . The Japanese ships were spotted by the which was patrolling offshore and alerted the Russian defences . Tōgō chose to attack the Russian coastal defences with his main armament and engage the Russian ships with his secondary guns . Splitting his fire proved to be a bad idea as the Japanese and six - inch guns inflicted very little significant damage on the Russian ships who concentrated all their fire on the Japanese ships with some effect . Although a large number of ships on both sides were hit , Russian casualties numbered only 17 while the Japanese suffered 60 killed and wounded before Tōgō disengaged . " Fuji " was hit by two shells during the battle that killed two and wounded 10 crewmen . On 10 March , " Fuji " and her sister " Yashima " , under the command of Rear Admiral Nashiba Tokioki , blindly bombarded the harbour of Port Arthur from Pigeon Bay , on the southwest side of the Liaodong Peninsula , at a range of . They fired 154 twelve - inch shells , but did little damage . When they tried again on 22 March , they were attacked by Russian coast defence guns that had been transferred there by the new Russian commander , Vice Admiral Stepan Makarov , and also from several Russian ships in Port Arthur using observers overlooking Pigeon Bay . The Japanese ships disengaged after " Fuji " was hit by a 12 - inch shell . " Fuji " participated in the action of 13 April when Tōgō successfully lured out a portion of the Pacific Squadron , including Makarov ' s flagship , the battleship . When Makarov spotted the six battleships of the 1st Division , he turned back for Port Arthur and " Petropavlovsk " struck a minefield laid by the Japanese the previous night . The Russian battleship sank in less than two minutes after one of her magazine s exploded , Makarov one of the 677 killed . Emboldened by his success , Tōgō resumed long - range bombardment missions , which prompted the Russians to lay more minefields . During the Battle of the Yellow Sea in August 1904 , " Fuji " was not hit because the Russian ships concentrated their fire on the leading ship of the column , Tōgō ' s flagship , the battleship . During the Battle of Tsushima in May 1905 , she was hit a dozen times ; the most serious of which penetrated the hood of the rear barbette , ignited some exposed propellant charges and killed eight men and wounded nine . After the ammunition fire was put out , the left gun in the barbette resumed firing and apparently fired the coup de grâce that sank the battleship . On 23 October 1908 , " Fuji " hosted a dinner for the American Ambassador and the seniormost officers of the Great White Fleet during their circumnavigation of the world . In 1910 , her cylindrical boilers were replaced by Miyabara water - tube boilers and her main armament was replaced by Japanese - built guns . " Fuji " was reclassified as a first - class coast defence ship that same year , and was used for training duties in various capacities until disarmed in 1922 . She spent all of World War I based at Kure . Her hulk continued to be used as a floating barracks and training center at Yokosuka until 1945 . " Fuji " was damaged by American carrier aircraft during their 18 July 1945 attack on Yokosuka and capsized after the end of the war . The ship was scrapped in 1948 .
