The Type 89 I-Go was a 13-ton tank fielded by the Imperial Japanese Army in the Sino-Japanese War and WWII. Massively produced, it entered service in 1931 and was mainly used in the infantry fire support role until 1945. It was fitted with a steel-plate riveted turret, excentrically situated towards the front on a long hull, which had an almost vertical glacis plate. This 360º-rotating turret mounted a 57-mm gun, which was underpowered compared to the 75-mm gun of Sherman M4 tank. It was also armed with two 6.5-mm machine guns and was operated by a crew of 4. The Type 89 I-Go was powered by one Mitsubishi A612OVD, 6-cylinder, gasoline engine, which generated 120 horsepower.
