GB-4's development began in 1944 as clear weather, good visibility weapon to attack heavily-defended targets; it was only useful against objectives readily identifiable on the crude CRT screens of the period. It featured a plywood airframe with twin booms and fins with a single elevator. The warhead was a 2000 pound (900 kg) general purpose (GP) bomb. The target was acquired by a television camera beneath the warhead, with a field of view 18° high and 14° wide, and the bomb was steered by radio command guidance, the operator tracking it by means of flares in the tail. It was intended to be carried externally, under the wing of a Boeing B-17 Flying Fortress or North American B-25 Mitchell. Release was at about 175 miles per hour (280 km/h) and 15,000 feet (4575 m) altitude, giving a range of 17 miles (27 km), with an average flight time of four minutes. Its accuracy was 200 feet (60 m).
The Pacific War ended before it entered combat.
