Mitsubishi Ki-67 Hiryu

The Mitsubishi Ki-67 Hiryu, meaning flying dragon, was a twin-engine bomber that the Allies code-named Peggy, used by both the Imperial Japanese Army and Navy air services in the Second World War. The army issued a 1941 specification for a successor to the Nakajima Ki-49, a fast heavy bomber with good defensive armament and the ability to survive battle damage. A team under Kyunojo Ozawa gave it an all-metal mid-wing airframe with self-sealing tanks and armour, making it unusually sturdy for a Japanese aircraft. It was used for level and torpedo bombing, as a kamikaze aircraft late in the war, and as the basis for the Ki-109 fighter. By the end of the war 767 had been produced.
