Type 3 Chi-Nu Medium Tank

The Type 3 Chi-Nu medium tank was another improvement over the Type 97 Chi-Ha line of medium tanks of the Imperial Japanese Army in World War II. The Type 3 Chi-Nu mounted one Type 3 75 mm Tank Gun, one of the largest guns ever to be fitted on a World War II Japanese tank.

The Type 3 Chi-Nu retained the same chassis and suspension of the Type 97 but in a large new hexagonal gun turret.

The main armament of the Type 3 Chi-Nu was the Type 3 75 mm Tank Gun with caliber of 75 mm, barrel length of 2.883 meters (L38.4). The gun could be elevated between -10 and +25 degrees. It had a muzzle velocity of 680 metres per second (2,200 ft/s) and an armor penetration of 90 millimeters at a range of 100 meters and 65 millimeters at a range of 1,000 meters. This gun was based on the Japanese Type 90 field gun which in turn was loosely based on the French Schneider et Cie Canon de 85 mle 1927.
