Japanese battleship Iwami (Japanese: 石見) was one of eight Russian pre-dreadnought battleships captured by the Imperial Japanese Navy during the Russo-Japanese War of 1904-1905. It was built as the Borodino-class battleship Russian battleship Oryol (Russian: Орёл), and was commissioned into the Imperial Russian Navy's Baltic Fleet. Some naval architects regard the Borodino-class as being among the worst battleships ever built (Preston 2002). The design was based on the battleship Tsesarevich, these ships suffered from instability caused by a high centre of gravity, which was made worse by overloading.
The Oryol was the only modern Russian battleship to survive the Battle of Tsushima. She was probably hit by five 12-inch (300 mm), two 10-inch (250 mm), nine 8-inch (200 mm), and 28 6-inch (150 mm) shells, and possibly a number of smaller rounds. She suffered only moderate damage, including two 6-inch (150 mm) turrets disabled by 8-inch (200 mm) hits. Her armour was fairly effective: a 12-inch (300 mm) shell hit the 5 ¾ inch belt obliquely and was repulsed, and a main battery turret resisted a 10-inch (250 mm) shell.
She was substantially rebuilt after her capture by the Japanese, reducing her top weight and removing the smaller guns, and commissioned into the Imperial Japanese Navy as the battleship Iwami, taking her name from an ancient Japanese province, of Iwami now part of Shimane prefecture. The name Iwami was chosen as this province was geographically the closest to the location of the Battle of Tsushima.
On 28 August 1912, the Iwami was re-classified as a 1st class Coastal Defense Vessel.
During World War I, the Iwami was active at the Battle of Tsingtao.
Under the terms of the Washington Naval Agreement, Japan agreed to scrap the Iwami. She was decommissioned on 09 May 1923, and expended as a target, sunk by aircraft launched from Jogashima island (near Yokosuka) on 10 July 1924.
