Oryol (Russian: Орёл) was a Borodino-class battleship built for the Russian Imperial Navy in the first decade of the 20th century.
Oryol was badly damaged during the Battle of Tsushima in May 1905 and surrendered to the Japanese who put her into service under the name of Iwami.
Reconstructed by the Japanese in 1905–1907, Iwami was reclassified by the Imperial Japanese Navy as a coastal defence ship in 1912.
Iwami was used as a training ship beginning in September 1921.
The ship was disarmed in 1922 to comply with the terms of the Washington Naval Treaty and sunk as a target ship.

Kongo was actually built by Vickers (and was
the last Japanese capital ship to be built outside of Japan), while the
remaining three were built in Japanese yards. During the inter-war
years, all of them were upgraded in terms of propulsion and protection,
and were re-rated as battleships.
KONGO is the only IJN battleship sunk by a submarine during the war and the last battleship ever sunk by a submarine.
