Chinese frigate Hai'an
Chinese wooden steam frigate
Hai'an (Chinese: 海安; pinyin: Hǎi'ān; Wade–Giles: Hai-an), originally named Zhen'an (simplified Chinese: 镇安; traditional Chinese: 鎮安; pinyin: Zhèn'ān; Wade–Giles: Chen-an), was a wooden steam powered frigate built for the Imperial Chinese Navy. She was the lead ship of the Hai'an class, which consisted of her and her sister Yuyuen. They were the largest vessels built in China until the 1930s; they each ran over budget and used sub-standard building materials which limited their use. Hai'an was initially used as a training ship, and later saw action in the Sino-French War as a potential blockship, being scrapped as a hulk following the war.
