Channel: Main Battle Tank
Date: 17/01/2023

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 at the time of its introduction Japan's laws did not allowed exporting military equipment.

   This artillery system has a heavily-modified Type 89 IFV hull, topped with an original turret, and is armed with a longer 155 mm/L52 version of the FH-70 towed howitzer, which is also used in Japan.

   Maximum range of fire is 30 km with standard HE-FRAG projectile and approximately 38 km with rocket assisted projectile. 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 heavy 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 Mitsubishi diesel engine, developing 600 horsepower. It is likely that it is the same Mitsubishi 6SY31WA engine, used on the Type 89 IFV. 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. A battery of the Type 99 howitzers also includes a mobile command post and fire control radar.
