Guided Bombs in Korea After World War II ended in 1945, work on guided bombs essentially halted. With the start of the Korean War in 1950, however, the Air Force expedited the development of these weapons. The Air Force used two guided bombs in Korea, the VB-3 Razon and VB-13 Tarzon, primarily against bridges. The Razon and Tarzon worked using the same method. A bombardier dropped and visually guided the weapon by radio control. The Razon and Tarzon bombs' flight control surfaces allowed them to be controlled in two axes (range, or up and down, and azimuth, left or right). They also carried a flare to assist visual tracking after release. Although the USAF had mixed results in Korea with the Razon and Tarzon, they foreshadowed the later widespread use of precision-guided weapons. Click here to return to the Strategic Bombing Overview.
