The Type 3 Chi-Nu was yet another improvement over the Type 97 Chi-Ha in a line of medium tanks started by the Type 1 Chi-He. The Type 3 retained the same hull and suspension of the Type 97 but in a large new turret the Type 3 mounted one Type 3 75 mm gun, one of the largest guns ever to be fitted on a Japanese vehicle during the Second World War. The Type 3 was designed to combat the American M4 Sherman, a tank which was far superior to any tank of the Imperial Japanese Army.
The main gun of Chi-Nu was the Type 3 75 mm Tank Gun with caliber of 75 mm, barrel length of 2.883 m (L38.4). The gun could be elevated between -10 and +25 degrees. It had a muzzle velocity of 680 meters per second and an armour penetration of 90 millimeters at a range of 100 meters and 65 millimeters at a range of 1,000 meters. The Type 3 gun was based on the Japanese Type 90 field gun which itself was based on the French 1919 75 mm Schneider Mountain gun.
Type 3 Medium Tank Chi-Nu was developed to cope with the M4 Sherman[citation needed]. It was originally intended that the tank to follow the Type 1 Chi-He was the Type 4 Medium Tank Chi-To. However, there were delays in the development of Chi-To, and as a result a stopgap tank was required. The development of Chi-Nu started in May 1944 and it was finished in October, just six months. The Chi-Nu was the last tank that was fielded by the Japanese armed forces, and was produced until the end of the war.
The Type 3 was allocated to the Japanese home islands to defend against an Allied Invasion that never materialised and therefore, never saw combat. According to recent Japanese sources approximately 200 were built
