As the war progressed, and as at the Japanese refined their kamikaze techniques, they began to develop aircraft explicitly for that purpose. The Yokosuka MXY-7 was a rocket-propelled aircraft that made its debut in September 1944. To build the machine, the Japanese used as little important raw materials as possible, and the plane's construction was extremely rudimentary.
During combat, the Ohka was carried under the fuselage of a Mitsubishi G4M until the target was within close range, when it was released. The pilot would try to glide as close to the target as possible before firing the rockets and smashing into the target.
The weapon was armed with a 2,643 pound warhead. Its intense speed made it virtually impossible to intercept by anti-aircraft fire. That said, along with the carrier plane, it was extremely vulnerable during the gliding phase. What's more, it was very difficult to steer once the rockets had been fired. Despite these limitations, at least one US destroyer was sunk by this weapon.
