Dingyuan

Dingyuan was an ironclad battleship and the flagship of the Chinese Beiyang Fleet. She was the lead ship of the Dingyuan class, which included one other vessel, Zhenyuan, both of which were built in Germany in the early 1880s. Delivery of the two ironclads was delayed by the Sino-French War of 1884–1885. The ships were armed with a main battery of four 12 in guns in a pair of gun turrets, making them the most powerful warships in East Asian waters at the time.

Dingyuan served as the flagship of Admiral Ding Ruchang during her active career. In the 1880s and early 1890s, the Beiyang Fleet conducted a routine of training exercises and cruises abroad, with emphasis placed on visits to Japan to intimidate the country. The latter resulted in the Nagasaki Incident in 1886 and contributed to a rise in hostility between the two countries that culminated in the First Sino-Japanese War in 1894.
