The Type 4 Chi-To was a medium tank used by Japan during World War II, though never put into service before the war ended.

Description[]

The Chi-To had a crew of five and a top speed of 45 km/h. It was powered by an air-cooled, 412 hp, Mitsubishi AL Type 4 V12 diesel engine.This engine was substantially more powerful than the Chi-Nu's 240hp engine, capable of pushing the 30 ton tank up to 45 km/h.It's operational range was 250 km. Protection-wise, the all-welded tank had a maximum armour thickness of 75 mm at it's front hull and turret. Armament-wise, the tank was armed with a single 75 mm Type 5 tank gun derived from captured Swedish AA guns in China (Bofors 75mm Model 1929), the gun had a muzzle velocity of 850m/s, penetrating 75mm armour plate at 1000m. The Chi-To had 1 hull-mounted Type 97 machine gun and an additional pintle mount on top of it's turret for another Type 97 machine gun.The Chi-To had no variants.

History[]

The Chi-To first began it's development in 1942 when the Rikugun Heiki Gyōsei Honbu (Army Weaponry Administrative Headquarters) asked for a new medium tank armed with a long-barreled 47 mm tank gun, Mitsubishi manufactured the first prototype in September 1942. The requirements later changed in 1943 to a long-barreled 57 mm tank gun and armour protection of 75 mm.The first prototype was up-gunned, but trials of the 57 mm gun shown dissatisfactory, so the 75mm tank gun was chosen instead. The second prototype was completed in February 1945 and was armed with 75 mm Type 5 tank gun and protected by 75mm of armour. The Chi-To never entered service.
