The Yokosuka MXY-7 Ohka (櫻花 Ōka?, "cherry blossom"; 桜花 in modern shinjitai orthography) was a purpose-built, rocket powered human-guided anti-shipping kamikaze attack plane[1] employed by Japan towards the end of World War II. United States sailors gave the aircraft the nickname Baka[2] (Japanese for "fool" or "idiot").
