GB-4 (Glide Bomb No.4) was a precision guided munition developed by the United States during World War II. GB-4s used a television guidance system with the weapon being steered by a TV bombardier operating a joystick in the launch aircraft. The first GB-4s (then known as MX-607s) were tested at Eglin Air Force Base during August of 1943. During testing the GB-4's circular error probable accuracy was found to be 200 feet (61 m). The type was ordered into production on the 15 January 1944. Although approved for operational use, the typed suffered from reliability problems throughout testing.
