The Republic of China Ministry of National Defence is preparing to significantly expand orders for American M109 155mm self propelled howitzers, which are set to increase from 40 to 168 vehicles, or 420 percent of previously planned levels. Defence officials have reportedly pointed to the system’s considerable 40 kilometre engagement range, which bridges the gap between existing howitzers, and the M142 High Mobility Artillery Rocket System (HIMARS) which have also been procured from the United States that boast 80 kilometre engagement ranges. The planned expansion of orders also follows a significant escalation of pressure from the United States to increase procurements of American armaments in exchange for continued military and political support. Orders for costly M982 Excalibur satellite guided rounds for the system are also expected to be placed, while some reports indicates that significantly increased procurements of other kinds of American equipment for the Republic of China Army are under consideration.
