IJN Ibuki (伊吹 巡洋戦艦 Ibuki junyōsenkan?) was the lead ship in the 2-vessel Ibuki class of 1st class heavy cruisers in the Imperial Japanese Navy. Ibuki was named after Mount Ibuki located between Gifu prefecture and Shiga prefecture in Honshū. On 28 August 1912, Ibuki and its sister ship Kurama were re-classified as battlecruisers by the Japanese navy.

[edit] Background

The Ibuki class was planned during the Russo-Japanese War and was authorized under the 1904 Supplemental Naval Budget, at the same time has the cruiser Tsukuba, but with heavier guns and with the new geared turbine engines which promised more power and hence, more speed. However, problems with the turbine engines delayed the construction of the Ibuki, and in the end, construction began almost two years later than her sister ship, the Kurama, which used standard reciprocating engines. Ibuki was built at Kure Naval Arsenal.

[edit] Service life

Shortly after commissioning, the Ibuki was sent on a voyage to Thailand to attend the coronation ceremony of the Thai king Rama VI Vajiravudh.

Ibuki played an important role in World War I as part of Japan's contribution to the Allied war effort under the Anglo-Japanese Alliance, in protecting British merchant shipping in the South Pacific and in the Indian Ocean, and participating in the hunt for the German East Asiatic Squadron and the SMS Emden .

After the war, Ibuki fell victim to the Washington Naval Treaty and was scrapped after a short service life of only 15 years.

Her guns were salvaged, and used in the shore batteries at Hakodate in Hokkaidō and along the Tsugaru Strait separating Honshū and Hokkaidō.
