Type 75

   Development of the Japanese Type 75 self-propelled howitzer began in 1969. First prototype was built in 1971. This artillery system entered service with the JGSDF in 1975. Production of the Type 75 ceased in 1988 with a total of 201 howitzers built. The Type 75 was not exported, as Japan's laws do not allow to export military equipment. The Type 75 is now gradually replaced by the Type 99 self-propelled howitzer.

   This self-propelled artillery system is fitted with indigenous 155-mm / L30 howitzer, fitted with an autoloader. It fires standard and rocket-assisted HE-FRAG projectiles, smoke and illumination projectiles. This howitzer is compatible with all standard NATO 155-mm ammunition. Maximum range of fire is 19 km with standard HE-FRAG round and 24 km with rocket assisted round. Maximum rate of fire is 6 rounds per minute.

   Secondary armament consists of 12.7-mm machine gun, mounted on top of the roof.

   Aluminum armor of the Type 75 provides protection against small arms fire and artillery shell splinters. It is fitted with an NBC protection and automatic fire suppression systems.

   The Type 75 SPH uses a number of automotive components of the Japanese Type 74 main battle tank. Vehicle is powered by the Mitsubishi 6 ZF diesel engine, developing 450 horsepower.
