History
The 4.7-inch/40 caliber Armstrong is a British naval gun originally developed for export in the 1880s and 1890s and intended to replace the BL 5-inch gun and use modern smokeless propellants such as cordite which would become standard on British warships and had a faster rate of fire with only a slightly lighter shell. Along with being used in Royal Navy and British Army during the Second Boer War and World War I, it also saw service in the Italian and Japanese navies. The Imperial Japanese Navy adopted it in 1890 as part of its modernization efforts. The first ship to use this in the IJN and in any navy for that matter is the Chidori an armored cruiser. The Japanese would start mounting more quick-firing guns on their cruisers.
During the First Sino-Japanese War, the Japanese Fleet was pitted against the Chinese Beiyang Fleet at the Battle of the Yalu River on the China-Korean border where six IJN cruisers with rapid-firing 4.7-inch Armstrong guns had a significant tactical advantage over the Chinese ships and won the battle. The Japanese would begin producing this gun under license as the Mark IVJ which was re-designated the Type 41 in 1908 (the 41st year of the reign of Emperor Meiji) and later re-designated again as a 12-centimeter gun in 1917 after the IJN switched to the metric system. During World War I, the Japanese joined the Allies due to the Anglo-Japanese Alliance of 1902 and provided 37 Type 41s for the Royal Navy who rejected it, but the guns would be used as coastal defense batteries such as Mersea Island, Essex and on British merchant ships defend them against German commerce raiders. Until 1920, the 4.7 inch was the IJN's standard secondary or tertiary armament for cruisers and the primary weapon for their destroyers most notably the Umikaze-class the first Japanese-built destroyers intended for open ocean service. Even when more powerful models came along to replace it as their naval weapon in the 12cm caliber, the IJN still had the gun in service during World War II.
