The Strategic Air Command (SAC) was formed to deter war against the emerging Soviet threat -and to fight and win a war if deterrence failed. This fascinating history of SAC will weave together six themes shaping the command during its first decade of existence: mission, message, education, technology, intelligence gathering and analysis, and leadership. All of these were crucial but the last is perhaps primus inter pares. General Curtis E. LeMay was the commander of SAC from 1948 to 1957. His leadership and drive were fundamental to the successful evolution of the command.
