Comments:
With the success of the Kamikaze the Imperial Navy decided to build an aircraft specifically designed for the task. The Ohka "Cherry Blossom" was to be carried to within range of the target by a Mitsubishi G4M that had it's bomb bay doors removed as well as other modifications. When the parent aircraft had reached roughly 50 from the target the Ohka was released and the pilot would hold the aircraft in a fast glide, around 290 mph, until a target had been chosen. The pilot would then ignite the rocket motor and push the aircraft over into a steep dive. Most of these aircraft failed to reach thier target, the parent aircraft proving to be vulnerable to interception. Numerous variants were proposed, including a submarine launched version but none saw service.
