Type 99

   The Type 99 self-propelled howitzer was developed as a replacement to the Type 75 SPH. It was developed by the Mitsubishi Heavy Industries and the Japan Steel Works. A small number of Type 99 self-propelled howitzers is currently in service with the Japanese Ground Self-Defense Force. It has not been offered for export customers, as Japan's laws do not allow exporting military equipment.

   The Type 99 self-propelled howitzer is fitted with 155-mm howitzer, which is believed to be 39 calibers long. Maximum range of fire is 30 km with standard HE-FRAG projectile and approximately 38 km with rocket assisted. Maximum rate of fire is speculated to be 6 rounds per minute.

   Secondary armament of the Type 99 consists of a roof-mounted 12.7-mm machine gun, fitted with a shield.

   Armor of the Type 99 provides protection against small arms fire and artillery shell splinters.

   Vehicle is powered by a diesel engine, developing 600 horsepower. A traveling lock is provided at the front of the hull. It folds back onto the glacis plate when not in use.

   The Type 99 self-propelled howitzer is resupplied from the Type 99 ammunition resupply vehicle.
