Ke-Go

Ke-Go was one of the first guided weapons, developed by the Imperial Japanese Army Ordnance Board. The Ke-Go was a free falling, infra-red guided, gyro-stabilized missile, intended to be dropped from airplanes onto shipping targets. The missile had eight wings in two cross-configurations, one set fore and one set aft. Output from the heat-seeking head was amplified to provide guidance control to flaps on the four forward wings. The main body was to hold an explosive charge behind the heat-seeking head.
