Command and Control

by Eric Schlosser

Once the target list was complete and the ground zeros identified, the planners calculated the most efficient way to destroy them. A wide assortment of variables had to be taken into account, including: the accuracy and reliability of different weapon systems, the effectiveness of Soviet air defenses, the impact of darkness or poor weather, and the rate at which low-flying aircraft were likely to crash due to unknown causes, known as the “clobber factor.” The Joint Chiefs specified that the odds of a target being destroyed had to be at least 75 percent, and for some targets, the rate of damage assurance was put even higher. Achieving that level of assurance required cross-targeting—aiming more than one nuclear weapon at a single ground zero. After the numbers were crunched, the SIOP often demanded that a target be hit by multiple weapons, arriving from different directions, at different times. One high-value target in the Soviet Union would be hit by a Jupiter missile, a Titan missile, an Atlas missile, and hydrogen bombs dropped by three B-52s, simply to guarantee its destruction.
