The Type 31 75 mm mountain gun (三十一年式速山砲 Sanjūichinen-shiki Sokusanhō) was the main field gun deployed by the Imperial Japanese Army in the Russo-Japanese War of 1904-1905.
Description
The Type 31 was introduced in 1898, with the “Type 31” designation indicating that the gun was developed in 31st year of reign of Emperor Meiji.[1] Designed by Colonel Arisaka Nariakira, it had a barrel made of steel, which improved the range and accuracy of the gun over the earlier 7 cm mountain gun, which had a bronze barrel. The Type 31 used smokeless powder cartridge shots, and had a semi-rigid recoil system using cables connected to a set of springs. It had a range of approximately 7800 meters, using a 6.0 kilogram explosive shot. The Type 31 also came in a lighter mountain gun version, which had a shorter range (4300 meters). Approximately 620 were produced and deployment to combat units was completed by 1902. The gun remained in service to the end of World War II.
