History

The Imperial Japanese Navy acquired a variety of naval guns from Britain prior to World War I. As Japan's shipbuilding slowly started to rise to a scale comparable to those in Europe, they still ordered ships and guns from Britain before producing the designs under license. Elswick Ordnance Works was a frequent seller of guns for Japan during this time period and the 6-inch/45-calibre Type 41 is another gun first purchased by them in 1904 before licensed production began in 1908 at Kure Naval Arsenal. Based on an export design called Pattern GG, the 6-inch gun was first used on the pre-dreadnought battleship Mikasa built by Vickers, the Kashima of the Katori-class, and the semi-dreadnought (having been laid down as an all-big-gun design before lack of industrial capacity caused the design to be scaled back) battleship Aki. By the time Kure Naval Arsenal began production under license, it would continue to see service with a number of different ships built by Japan mostly from the pre-World War I period. The Aso (ex-Bayan) and Tsugaru (ex-Pallada) cruisers captured from the Russians after the Siege of Port Arthur during the Russo-Japanese War were refitted with these guns. The guns were also used on the Tsukuba-class armoured cruisers, the IJN's final protected cruisers of the Chikuma class, and their first dreadnoughts of the Kawachi class. By the time this last class of ships was ordered, the Imperial Japanese Navy had switched to the metric system and so the guns were re-designated 15 cm/45 Type 41s though the guns were unchanged. After World War I, most of these ships were ultimately scrapped for one reason or another, but the guns would be salvaged and used during World War II as coastal artillery pieces.
