Yokosuka MXY-7 Ohka
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 that was produced by the Yokosuka Naval Air Technical Arsenal and deployed by Japan toward the end of World War II. Allied personnel commonly referred to the aircraft as "Baka Bombs" (baka being a Japanese pejorative term meaning "fool" or "idiot"). The Ohka was conceived during 1943 by Ensign Mitsuo Ohta and, following design assistance from the Aeronautical Research Institute of the University of Tokyo, received formal approval to proceed from the Imperial Japanese Navy on 16 August 1944.
