Yokosuka MXY7 Ohka model 11 [Rail launch]

The Yokosuka MXY-7 Ohka (櫻花), Ōka, "cherry blossom"; 桜花 in modern orthography) is a purpose-built, rocket-powered human-guided kamikaze attack-aircraft deployed by Japan against Allied ships in the Pacific Ocean theater towards the end of World War II. Although extremely fast, the Ohka had a very short range, so it had to be carried into action as a parasite aircraft by a much larger bomber, which was itself vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, Ohkas succeeded in sinking or damaging some escort-vessels and transport ships, but never sank any major warships. The Japanese developed improved versions in an attempt to overcome the aircraft's shortcomings, but they came too late for deployment. Allied personnel referred to the aircraft as "Baka Bombs" (baka being a Japanese pejorative term meaning "fool" or "idiot"). The MXY-7 Navy Suicide Attacker Ohka was a manned flying bomb that was usually carried underneath a Mitsubishi G4M2e Model 24J "Betty" bomber to within range of its target. On release, the pilot would first glide towards the target and when close enough he would fire the Ohka's three solid-fuel rockets, one at a time or in unison,[4] and fly the missile towards the ship that he intended to destroy. The design was conceived by Ensign Mitsuo Ohta of the 405th Kōkūtai, aided by students of the Aeronautical Research Institute at the University of Tokyo. Ohta submitted his plans to the Yokosuka research facility. While Ohta had started work on the design in 1943 the authorities would not take an interest until the following year. The Imperial Japanese Navy decided the idea had merit and Yokosuka engineers of the Yokosuka Naval Air Technical Arsenal (Dai-Ichi Kaigun Koku Gijitsusho, or in short Kugisho) created formal blueprints for what was to be the MXY-7. The only variant which saw service was the Model 11, and it was powered by three Type 4 Mark 1 Model 20 rockets. 155 Ohka Model 11s were built at Yokosuka, and another 600 were built at the Kasumigaura Naval Air Arsenal.
