JMSDF was eager to introduce automated GFCS that supported automatic radar tracking, such as the American Mk 56, but it was rejected by the US Navy. Under the FY1955 program, a budget for purchasing one automated FCS overseas was approved. Jaberg (manufactured by Contraves) was selected and installed in
