Concept
Chinese cruiser Ning Hai
Summary
Ning Hai () was a light cruiser in the Republic of China Navy (ROCN) before World War II and the lead ship of her class. She was sunk in the early days of the Second Sino-Japanese War by aircraft from the Imperial Japanese Navy, and her wreck was raised and repaired by the Japanese, re-entering service with the Japanese Navy in the Pacific War as the escort vessel Ioshima. She was sunk again in September 1944 by a USN submarine.
By the end of the 1920s, the ROCN had only four antiquated 19th century protected cruisers and two training cruisers received before World War I. The Kuomintang government had an ambitious re-armament plan but lacked funds, and after extensive negotiations with shipbuilders in the United States, United Kingdom, Germany and Japan, placed an order with the Japanese for one light cruiser to be built in Japan, with a second vessel to be built in China with Japanese assistance. Despite the very strained political relations between Japan and China and the strenuous objections of the Japanese military, Harima Shipyards completed the first cruiser in 1932.
Ning Hai was based on the experimental Japanese cruiser , which combined a small size with heavy weaponry, but in an even smaller displacement of only . As with Yūbari, Ning Hai has a single trunked smokestack, and a tripod bridge arrangement. Her weaponry was comparable to ships with a larger displacement: six 14 cm/50 3rd Year Type naval guns mounted in three double gun turrets, six 8 cm/40 3rd Year Type naval guns, and dual 533-mm torpedo tubes. Ning Hai also had a small hangar for two seaplanes; two Aichi AB-3 biplanes, one bought from Japan and one built locally using a spare engine and domestic materials, were assigned to it. There was no aircraft catapult, and the seaplanes were hoisted onto and deployed using a crane.
However, the vessel was underpowered, with three antiquated vertical four-cylinder triple-expansion steam engines, two of which were coal-fired, yielding a top speed of only 22 knots. The excessive top-weight of the design also created stability problems.
