The “bomber-gap” controversy was soon followed by a “missile-gap” controversy, provoked by an extensive Soviet propaganda campaign that claimed a substantial Soviet lead in developing and deploying ICBMs. U-2 missions searched huge stretches of the Soviet Union along the rail network, looking for ICBMs deployed outside the known missile testing facilities. These missions enabled the CIA to conclude, as Dulles explained to Congress in May 1960, that “the Soviet ICBM program has not been and is not now a *crash* program; instead, it is an orderly, well-planned, high-priority program aimed at achieving an early ICBM operational capability.”¹ As with the controversy over Soviet bomber strength, information from U-2 photography enabled President Eisenhower to resist pressure to accelerate the US missile deployment program by building obsolescent liquid-fueled missiles rather than waiting to complete the development of more reliable solid-fueled missiles.
U-2 missions also gathered considerable data on the Soviet Union’s atomic energy program, including the production of fissionable materials, weapons development and testing activities, and the location and size of nuclear weapons stockpile sites. Such U-2 photography also revealed no evidence that the Soviet Union had violated the nuclear testing moratorium.
One of the greatest contributions of the U-2 program was to increase the capabilities of the US deterrent force. Before the U-2 overflights, most target information was based on obsolete materials dating back to World War II or shortly thereafter. With the assistance of U-2 photography, the Defense Department could allocate weapons and crews more efficiently and identify many new targets. U-2 photos also proved invaluable in determining the precise location of targets. One further contribution to the capabilities of the US deterrent force was the information that U-2s collected on the Soviet air defense system. U-2 photography located Soviet fighter airfields and gained intelligence on new fighter models. Special electronic intercept and recording equipment carried on many U-2 missions enabled the CIA to analyze the technical characteristics, operational techniques, and radar order of battle of the Soviet Union’s electronic defenses. This information was vital both for planning the routes for US deterrent forces and for developing electronic countermeasures.
