Daihatsu-class landing craft

The Daihatsu-class or 14 m landing craft (大発, abbreviation of 大型発動機艇 which means "large motorized boat") was a type of landing craft used by the Imperial Japanese Army from 1937 to 1945, in the Second Sino-Japanese War and World War II. It had a bow ramp that was lowered to disembark cargo upon riding up onto a beach. After reviewing photos of a Daihatsu landing craft, this was adopted by American landing craft designer Andrew Higgins in developing the Landing Craft, Personnel (Large) (LCP(L)) into the Landing Craft, Personnel (Ramped) (LCP(R)) and later the Landing Craft, Vehicle and Personnel (LCVP). However, the Daihatsu landing craft was more seaworthy than an LCVP due to its hull design. It was constructed of a metal hull and powered by a diesel engine.
