The two Naniwa-class cruisers (浪速型防護巡洋艦, Naniwa-gata bōgojun'yōkan) were protected cruisers built for the Imperial Japanese Navy (IJN) during the 1880s. As Japan lacked the industrial capacity to build such warships herself, the vessels were built in Britain. Both ships participated in numerous actions during the First Sino-Japanese War of 1894–1895 and in the Russo-Japanese War of 1904–1905.

Background

The 1876

Qing China.[1] The Chinese made no significant response at that time and King Gojong began a modest effort to modernize the country to allow it to better withstand foreign pressure. This upset conservative elements in the army and the population which led to the Imo Incident of 1882 where the rioters attacked the Japanese Legation, forcing the diplomats to take refuge aboard a British ship and in the royal palace. The Chinese sent troops that crushed the rebellion and they reasserted control over Joseon, reducing it to a vassal state, rather than resuming its previous pro-forma tributary status.[2]

Concerned about the rising power of Imperial Russia and Japan, Li Hongzhang, Viceroy of Zhili Province, and generally responsible for relations with Russia, Korea and Japan[3] had begun a program of gradually expanding the Beiyang Fleet after the 1874 Japanese reprisal expedition to Taiwan. An 1880 order for two Dingyuan-class ironclads from the German Empire capped the program as neither the Imperial Russian Navy nor the IJN could match them once they were delivered.[4]

In response the Japanese

naval architect, William White, to build two improved versions of the pioneering Chilean protected cruiser Esmeralda (later purchased by the IJN and renamed Izumi).[5]

The "Elswick"-type protected cruisers, of which Esmeralda was the first example, had been designed by White's predecessor, George Rendel, for Armstrong Mitchell as a private venture. It was of great interest to Japan because of her high speed, powerful armament, armor protection and relatively low cost, especially since the IJN lacked the resources at the time to purchase ironclads.[6]

Pioneering Japanese naval architect Sasō Sachū requested that Armstrong Whitworth make modifications to the Esmeralda design to customize it for Japanese requirements, and two vessels, Naniwa and Takachiho were ordered under the 1883 fiscal year budget, by Naval Minister Kawamura Sumiyoshi. When completed, Naniwa was considered the most advanced and most powerful cruiser in the world. However, the extremely fast development of technology, weaponry and armor in this field of ship design meant that the supremacy of this design was very short.

The two cruisers together cost

, who made a toast that "the ship was destined to the service of a country which was likely never to come into collision with our own peace-loving country".

The ships were powered by a pair of horizontal, two-cylinder

kW) with forced draught to give the ships a maximum speed of 18 knots (33 km/h; 21 mph). During their speed trials, the cruisers reached speeds of 18.72–18.77 knots (34.67–34.76 km/h; 21.54–21.60 mph) from 7,235–7,604 ihp (5,395–5,670 kW). They carried enough coal to gave them a range of about 9,000 nautical miles (17,000 km; 10,000 mi) at a speed of 13 knots (24 km/h; 15 mph).[9] The ship's crew consisted of 338 officers and ratings.[7]

Ships in class

Two Naniwa-class cruisers were purchased from Armstrong Whitworth in England. Naniwa was lost before the start of World War I, Takachiho was lost soon after hostilities commenced.[10]

Naniwa

Ordered in 1883, launched 18 March 1885, and completed 1 December 1885, Naniwa played a major role in the

Kurile Islands .[10]

Takachiho

Ordered in 1883, launched 16 May 1885, and completed 1 December 1885, Takachiho participated in the

Battle of the Yalu River in the First Sino-Japanese War. In the Russo-Japanese War she was present at the opening Battle of Chemulpo Bay, but was subsequently assigned a reserve role. In World War I, while covering the invasion of German-held Qingdao, she was torpedoed by the German torpedo boat S90 on 14 October 1914 and sank with the loss of 271 officers and men.[10]
