The last heavy bombers used in large quantities by the Japanese army was also the best. The Mitsubishi Ki-67 Hiryu ("Flying Dragon") was extremely maneuverable, fast, and well armed. The plane reached combat units when it was too late to change the course of the war. The Ki-67 ("Peggy" in the Allied code) saw duty in the Japanese counteroffensive at Iwo Jima and in the Marianas, as well at during the American landing at Okinawa. Priority was given to the production of Ki-67s until the end of the war. The army authorities issued specifications for the successor to the Nakajima Ki-49 Donyru in February, 1941, and Mitsubishi took up the project. The first of three prototypes was ready in December of 1942, with testing beginning at the end of that year. No major problems were encountered; in fact the plane's performance was so satisfactory that it was decided to adapt it for torpedo duty as well. Some of these aircraft were later given to the Navy, where they were designated Yasukuni. The Ki-67 made its operational debut as a torpedo plane in October of 1944, during the combined air and naval battles off the coast of Formosa. Subsequently the Hiryu was used jointly by the army and navy in all major operational theaters. A total of 698 Ki-67s were built. Another aircraft was also derived from the Ki-67, which was a heavy fighter interceptor known as the Ki-109.
