The gap in the ballistic missile arsenals did not exist except in exaggerated estimates, made by the Gaither Committee in 1957 and in United States Air Force (USAF) figures.
John F. Kennedy is credited with inventing the term in 1958 as part of the ongoing election campaign in which a primary plank of his rhetoric was that the Eisenhower administration was weak on defense.
Senator John F. Kennedy stated "the nation was losing the satellite-missile race with the Soviet Union because of… complacent miscalculations, penny-pinching, budget cutbacks, incredibly confused mismanagement, and wasteful rivalries and jealousies.
National Intelligence Estimate (NIE) 11-10-57, issued in December 1957, predicted that the Soviets would "probably have a first operational capability with up to 10 prototype ICBMs" at "some time during the period from mid-1958 to mid-1959."
[4] Curtis LeMay argued that the large stocks of missiles were in the areas not photographed by the U-2s, and arguments broke out over the Soviet factory capability, in an effort to estimate their production rate.
In a widely syndicated article in 1959, Joseph Alsop even went so far as to describe "classified intelligence" as placing the Soviet missile count as high as 1,500 by 1963, while the US would have only 130 at that time.
Disagreements between the future capabilities of the Soviet Union to produce ICBMs by members of the National Security Council leaked to the public causing the false notion of a missile gap.
Alsop’s ideas would appeal to John F. Kennedy who incorporated them in his election campaigns that criticized the Eisenhower administration for allowing a missile gap to exist.
[7] Hawkish members of Congress, such as Senator Stuart Symington, continued to beat the drums about the alleged missile gap in an effort to pressure the president to increase spending on military hardware.
President Eisenhower resented being bullied based on inaccurate information and was beginning to formulate the term "military-industrial complex" to describe the close nexus between U.S. politicians and the defense industry.
[10] In an attempt to defuse the situation, Eisenhower arranged for Kennedy and Lyndon Johnson to be briefed on the information, first with a meeting by the Joint Chiefs of Staff, then Strategic Air Command, and finally with the Director of the CIA, Allen Dulles, in July 1960.
More satellite overflights continued to find no evidence, and by September 1961, a National Intelligence Estimate concluded that the USSR had no more than 25 ICBMs and would not possess more in the near future.
"[13] During a transition briefing, Jerome Wiesner, "a member of Eisenhower's permanent Science Advisory Committee,... explained that the missile gap was a fiction.
[13] Paul Nitze, Assistant Secretary of Defense for International Security Affairs, told the Soviet Ambassador to the United States that the missile gap favored the US.
We were harboring fears we didn't need to harbor.Warnings and calls to address imbalances between the fighting capabilities of two forces were not new, as a "bomber gap" had exercised political concerns only a few years earlier.
As Corona could find the sites no matter where they were located, the Soviets decided not to build large numbers of R-7s and preferred more-advanced missiles that could be launched more quickly.
Albert Wohlstetter, a professor at the University of Chicago, accused the CIA of systematically underestimating Soviet missile deployment in his 1974 foreign policy article, "Is There a Strategic Arms Race?"
As the weapon is set up to go off automatically if the USSR is attacked, which occurs as the movie progresses, the president is informed that all life on the surface will be killed off for a period of years.
