Description
Type90 tank is a third-generation tank developed to counter the Soviet threat
For the main gun, the 120mm Rheinmetall L44 smoothbore gun was adopted after comparison with domestic guns, and its FCS with automatic tracking function using infrared hot points, etc. and automatic loading system ensure high hit accuracy even between runs.
It is the first Japanese tank to use composite armor, and unlike the Type 74 tank, which used sloped armor and had a rounded shape, this tank has a square shape.
Its weight was increased to 50 tons from the Type74 tank’s 38 tons, so a 1500-horsepower engine and automatic transmission were adopted to give it excellent mobility.
While Type74 tank were able to tilt their chassis forward and backward, left and right, Type90 tank can tilt only forward and backward
