The Type 41 10-inch (254 mm)/40-caliber naval gun was the used on the British-built semi-dreadnought "Katori" class and "Satsuma" class battleships of the Imperial Japanese Navy.

History

The Type 41 10-inch naval gun was designed by Vickers specifically for the Imperial Japanese Navy, and was of a very similar design to the Vickers Mark VI and Mark VII guns produced initially for the Chilean Navy and later used in Royal Navy service.

The "Kashima" class used these weapons as secondary armament. The "Satsuma" class was originally intended to be built with all 12-inch guns, which would have made this class the first true all big gun dreadnought class in the world; however, budgetary constraints forced the Japanese navy to use a mixture of 12-inch and 10-in guns, as per the previous "Kashima"-class.

The gun was officially designated as “Type 41” from the 41st year of the reign of Emperor Meiji on 1908-12-25. It was further re-designated in centimeters on 1917-10-05 as part of the standardization process for the Imperial Japanese Navy to the metric system.

After the scrapping of both the "Katori"-class and the "Satsuma"-class under the terms of the Washington Naval Treaty in 1923, the guns were salvaged and used in coastal artillery batteries. The guns formerly on the "Aki" were re-used in fortifications around Tokyo Bay.

The Type 41 10-inch gun fired a convert|518|lb|kg|1|adj=on shell with either an armor piercing, high explosive or general purpose warhead.
