One of the largest ships built in China between world wars; in some sources she is classified as sloop. Real name of ship was Yi Hsien, but in newspapers of that time, and then and in literature, ship was named Yat Sen, that is perusal of the same hieroglyphs on Canton dialect. She was designed on the basis of Yung Sui, but with significantly increased dimensions, improved hull form, armoured conning tower and stronger armament (stern 120mm gun was replaced by 140mm). CT, probably, was protected by splinterproof armour. On trilas ship made 20kts at about 6000hp. Modernizations: None.
23.9.1937 Yat Sen was damaged by aircraft from Japanese carrier Kaga on Yangtze at Jiangyin and 26.9.1937 sunk by them in the same place. She was salvaged by Japanese in 1938, repaired, rearmed, partly rebuilt at Kure and commissioned by IJN as TS Atada. 25.8.1946 ship was returned to China and commissioned as gunboat Yi Hsien. In 1949 Yi Hsien left to Taiwan; in the early fifties she was converted to TS and stricken in 1960s.
