History

The development of a heavy spin stabilised rocket mortar was started in 1942 to replace the Type 98 32 cm Spigot Mortar. The first prototypes used a large steel launch tube but this proved to be overly complex and a simpler triangular frame with wooden rails was designed. Mass production started in late summer 1943 and by early 1944 several Rocket Battalions had been formed and equipped with this new weapon. The Type 4 was used in combat for the first time during the Battle of Luzon where over a 1,000 were fired, it was also used during the fighting on Iwo Jima and Okinawa. Many launchers and rockets were also stockpiled in Japan for the expected invasion.
