Jiangnan Shipyard
In the Warlord Era, both "Yongjian" and its sister ship "Yongji" were originally part of the fleet of the Zhili clique, but subsequently defected to the Kuomintang government in Nanjing. On August 25, 1937, "Yongjian" was sunk by a Japanese aerial attack in Jiangnan Shipyard, but the Japanese occupation force raised the ship and rearmed it with Japanese guns to enter Japanese service on October 15, 1938, renamed "Asuka" (飛鳥). "Asuka" first served as a torpedo-boat mothership but eventually, in 1940, served as a liaison ship until it was sunk by American aerial attack on May 7, 1945 in the Huangpu River.
