The was developed to carry the 130 mm rocket system developed by the Aerospace Division of the Nissan Motor Company. It used the suspension, tracks and diesel engine of the Type 73 Armored Personnel Carrier. Komatsu was responsible for the chassis and IHI Aerospace, as Nissan's Aerospace Division has since been renamed, for the launcher and its rockets. 15 Type 75 wind measurement vehicles were built on the same chassis to provide weather information for the rockets. The rockets are fin-stabilized. They can be fired individually or in a 12 second ripple.
