(2) Why did each country accent particular elements of an air defense strategy at various periods between 1945 and 1972? The first question concerns the means that leaders chose for de­fense against an increasingly sophisti­ cated offensive threat. For the most part, the history of that sequential selection of defenses from avail­able technology and budgetary resources is a matter of evidential fact. In Chapters IV and V and several appen­ dices of chronologies, tables, charts, maps and notes, this volume provides a distillation of those facts for the 1945–1955 period. The second question, by far the more difficult of the two, con­cerns elite perceptions and motivations— the calculus of costs and returns whereby leaders assessed threats, risks and capabilities and devised stra­ tegy. The evidence provided by research on the first question offers only partial explanations for the second; observable weapons systems do not explain but only manifest prior decisions. Chapters I to III offer judg­ ments about the relative importance of those decisions between 1945 and 1955 and about internal versus external factors that sustained the alloca­tion of enormous Soviet and American resources to homeland defense against enemy bomber and missile threats. For purposes of description and analysis, the post–World War II decade is logically split by the water­ shed outbreak of the Korean War in June 1950. Before 1950, American deployment of resources for air defense reflected the severe budget ceilings imposed on military planners, who generally sympathized with the post war emphasis on economic growth for civilian consumption. After 1950, all aspects of American air defense were expanded. During the pre-1950 period, constrained by limited budgetary resources, military planners concerned with civil defense succeeded in transferring responsibility for that element of air and missile defense to a civilian planning agency, dependent for execution of plans on state and local civil defense volunteers. By 1950, increasing civilian scientist concern with possible Soviet nuclear attack had sensitized public opinion to the problem. The Federal Civil Defense Act of 1950 established a civil defense operating agency; but Congress then appropriated only token budgets for what was clearly perceived to be a “mobilization,” not a peacetime institution. Although the desirability of a nationally unified and integrated air defense command and control system was recognized early, limited resources helped delay the evolution from the Army Air Forces’ impoverished Air Defense Command, established in March 1946, through the Continental Air Command (December 1948) to a Continental Air Defense Command in September 1954. Within the Air Force after 1950, competition 1 History of Strategic Air and Ballistic Missile Defense, 1945–1955: Volume I among differing func­tions (interceptor; penetration; tactical fighter) encouraged the conver­sion of older jets to the interceptor role (e.g., the F-88 which became the F-101). Still, the need for a “1954 interceptor” and the 1950–1951 competi­tion yielded the XF-92 (later the F-102). It was also limited budgets which constrained military planners from demanding expensive jet intercep­ tors before 1950, althou
