IJN 3rd Fleet

The 3rd Fleet (第三艦隊, Dai-san Kantai^?) was a fleet of the Imperial Japanese Navy (IJN), which was created, and subsequently disbanded on six separate occasions and revived on five separate occasions.

First established on 28 December 1903, the 3rd Fleet was created by the Imperial General Headquarters as an administrative unit to manage vessels considered obsolete for front-line combat service. These vessels were used primarily for training and for coastal patrol duties. The 3rd Fleet came under the aegis of the Combined Fleet for the duration of the Russo-Japanese War from March 1904. Although initially derided as a "dinosaur fleet", the 3rd fleet proved invaluable at the Battle of Tsushima and the Invasion of Sakhalin. It was disbanded on 20 December 1905.

The 3rd Fleet was revived on 24 December 1908 as an expeditionary force during the Chinese Republican Revolution, to safeguard Japanese interests (civilians and property) on the Chinese mainland and (if necessary) to conduct emergency evacuation. It was nicknamed the "South China Fleet" after its chief area of envisioned activity was the South China Sea. Its cruisers patrolled the Yangtze River and other large rivers in China, and its headquarters was based in the Japanese concession in Shanghai. It was disbanded on 25 December 1915.

The 3rd Fleet was reconstituted on the same day as the dissolution of the "South China Fleet", initially to act as a training force to supplement Japan's contribution to the World War I under the terms of the Anglo-Japanese Alliance. When the Russian Revolution was proclaimed by the communist forces in Russia, the mission of the 3rd Fleet was changed to that of patrols of the Russian sea coast for the Siberian Intervention by Japanese ground forces in support of anti-Bolshevik forces. The 3rd Fleet was disbanded on 1 December 1922, and many of its vessels were scrapped almost immediately under the terms of the Washington Naval Treaty.
