During the mid-1950s the United States Air Force was given its most powerful single-seat, two-engine fighter to date. The Voodoo would be deployed before the end of that decade in the tactical nuclear bomber and tactical reconnaissance roles world-wide, and in homeland defense with the two-seat, all-weather variant. In December 1957 it took the World Air Speed Record to Mach 1.6 - over one and a half times faster than the sound barrier.
