The impact of CORONA on American intelligence gathering was tremendous. With the success of Discoverer 14, which returned 16 pounds of film and provided more coverage of the Soviet Union than all preceding U2 flights, for the first time the United States had a clear picture of the USSR's strategic nuclear capabilities. Before CORONA, the National Intelligence Estimates (NIE) of CIA were highly uncertain and strongly debated. Six months before Discoverer 14, an NIE predicted that the Soviets would have 140-200 ICBMs deployed by 1961. A month after the flight of Discoverer 14, that estimate was refined to just 10–25.
