The V1, which may be seen as the first
cruise missile, was used operationally against
London and
Antwerp. The V-2
ballistic missile was used operationally against London, Antwerp, and other targets. The Rheinbote was fired against Antwerp.
The
Mistelcomposite aircraft configuration was used (with almost no effects) on the front lines both on western and eastern front. This system was composed by a bomber filled with explosive, coupled to a fighter plane: the pilot in the fighter plane flew the two coupled airplanes up to near the target, then he disconnected the aircraft and commanded the bomber to crash onto the target by radio control.
