Public misperceptions in 1959 and 1960 that the Soviet Union had opened up a dangerous and growing lead over the United States in the deployment of intercontinental ballistic missiles (ICBMs) had fateful consequences beyond influencing an exceedingly close presidential election. What was then labeled “the missile gap” also helped establish patterns in the nuclear arms race that persisted throughout the Cold War and beyond.
For the U.S. public, the missile gap burst forth spectacularly toward the end of the 1950s as a result of two developments in 1957. The first was the successful flight test of the Soviet SS-6 ICBM in August and the Soviet Union’s launch several weeks later of the world’s first artificial satellite, Sputnik, by the same rocket type. Both launches represented Soviet technological achievements not yet matched by the United States. Sputnik, visible in the night sky over the United States, was the more dramatic symbol of Soviet progress, but the ICBM test that preceded it had the more ominous and immediate security implications.
The second development was the secret completion in November and public discussion shortly thereafter of a presidentially commissioned review of U.S. nuclear policies by an outside and predominantly civilian committee, chaired by Horace Rowan Gaither. The Gaither Report, as it was called, warned that the Soviet Union could have a “significant” ICBM capability by the end of 1959, making the Strategic Air Command’s bomber fleet vulnerable to surprise attack “during a period of lessened world tension.” [1] Although classified top secret, some of the report’s conclusions, including its alarmist view of Soviet ICBM capabilities, were leaked to the press.
