Japanese L2D1 or L2D2 Navy type 0 Transport Model 11, a license-built copy of a DC-3/C47. About 500 were built, some versions having plywood skins on ailerons and elevators, some using considerable amounts of wood in the structure. After the war, the wood-and-metal versions were tested and found to outperform all-metal DC3s, but there were serious structural faults that grounded them.
