The Type 4 40 cm rocket mortar (四式四〇糎噴進, Yonshiki yonjū-senchi funshinhō) was a 400 mm (16 in) rocket used by the Imperial Japanese Army in the final stages of World War II.
Development and design
The Type 4 rocket mortar was developed in the final stages of World War II by the
Japanese home islands
.
Unlike the
Type 4 20 cm rocket, which could be launched from an ordinary pipe or culvert with sufficient diameter, wooden rails, or even directly from a slope in the ground,[1] the Type 4 40 cm rocket required specially designed launch rails.[2]
