As discussed in this first volume of Famous Planes: Superplanes, the McDonnell Douglas F-4 Phantom was widely used by the United States Airforce for ground attacks in Vietnam. The F-4 Phantom fighter-bomber was originally developed for the U.S. Navy in 1960, and later adopted by both the U.S. Marines and the U.S. Air Force. It was used extensively during the Vietnam War, both as the principal air superiority fighter, as well as being important in the ground-attack and reconnaissance roles.
