This ship paper model is the Naniwa, the lead ship of the Naniwa-class cruisers, the papercraft was designed by etsutan. Naniwa was built in the Newcastle upon Tyne-based Armstrong Whitworth Elswick shipyard in the United Kingdom. Together with her sister ship, Takachiho, these were the first protected cruisers acquired by the Imperial Japanese Navy. The name Naniwa comes from an ancient name for Osaka, which appears in the Nara period chronicle Nihon Shoki. She played a major role in the First Sino-Japanese War of 1894-1895.
The revolutionary design of the “Elswick” protected cruiser, initially developed as a private-venture by Armstrong Whitworth in the mid-1880s, and implemented in the cruiser Esmeralda for the Chilean Navy was of great interest to Japan because of its high speed, powerful armament, armor protection and relatively low cost, especially since the Imperial Japanese Navy lacked the resources at the time to purchase modern pre-dreadnought battleships. 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. When completed, Naniwa was considered the most advanced and most powerful cruiser in the world.
The design of Naniwa and Takachiho was based on a steel hull with high freeboard to increase seaworthiness. Compared with Izumi, the armor was stronger and the coal bunkers formed an additional shield around critical areas. The hull was split into multiple watertight compartments, with a double bottom. Both ships were equipped with naval rams as was standard for the time.
Propulsion was by two horizontal two-cylinder double expansion steam engines, with six cylindrical boilers, which provided for a design speed of 18 knots.
As built, her main armament initially consisted of two 260 mm (10 in) L/35 Krupp cannons mounted individually on rotating platforms in the bow and stern, with a supply of 200 rounds per gun. Secondary armament was initially six 150 mm (5.9 in) L/35 Krupp cannons mounted in semi-circular sponsons on the main deck, with 450 rounds per gun. Light armament included six QF 6 pounder Hotchkiss guns, ten 1-inch Nordenfelt guns and four 11-mm, 10-barrel Nordenfelt guns. In addition, there were four 356 mm (14.0 in) Whitehead torpedo tubes mounted on the main deck. After the First Sino-Japanese War, both Naniwa and Takachiho were re-armed with eight Elswick QF 6 inch /40 naval guns in order to increase stability and standardize on ammunition for the fleet.
