JGSDF TYPE 99 HSP The Type 99 155mm HSP (Self-Propelled Howitzer) will be delivered to division artillery regiments to shell enemy artillery units and to support Japanese combat units on the front line with its fire power. This new HSP is expected to replace the current Type 75 155mm HSP. Mitsubishi Heavy Industries, Ltd. was the primary contractor, developing the main gun and the turret. The vehicle is powered by a diesel engine. In a period of planned force reduction, the Japan Ground Self-Defense Force (JGSDF) planning calls for additional Type 99s. The 99-Type ammunition loading vehicle supports the Type 99 155mm HSP. It loads the ammunition and the like for the 99 type self-propelled 155mm howitzers.
