The Special Type 3 Launch Ka-Chi (特三式内火艇 カチ, Toku-san-shiki uchibitei Ka-Chi) was an amphibious medium tank developed by the Imperial Japanese Navy in World War II. The Type 3 Ka-Chi was based on an extensively modified Imperial Japanese Army Type 1 Chi-He medium tank (it had 2 more road-wheels and two more return rollers on each side) and was a larger and more capable version of the earlier Type 2 Ka-Mi amphibious tank.
