Most famous of these are the V-1 flying bomb and V-2, both of which used a simple mechanical autopilot to keep the missile flying along a pre-chosen route. Less well known were a series of anti-shipping and anti-aircraft missiles, typically based on a simple radio control system directed by the operator. However, these early systems in World War 2 were only built in small numbers. (Excerpt from Wikipedia)
