GB-4 is a glide bomb which is launched from an aircraft and guided by remote radio control to its surface target by employing television intelligence picked up by a television camera on the missile and radioed to a receiver in the launching plane. It has a special plywood airframe built around a 2,000 pound bomb, with rudders and elevators but no ailerons. The airframe is fastened to a magnesium casting threaded to the tail of the bomb.
The Destructor T9 is placed in the control box and is actuated, on impact, by the Fuze T62.
