 However, starting in the mid-1960s, the Soviets began to gain parity with the US and now had the potential capability to target and successfully attack the Minuteman force with an increased number of ICBMs that had greater yields and accuracy than were previously available.Studying the problem, even more, SAC realized that in order to prevent the US from launching all 1000 Minuteman ICBMs, the Soviets did not have to target all 1000 Minuteman missile silos.The Soviets only needed to launch a disarming decapitation strike against the 100 Minuteman LCCs – the command and control sites – in order to prevent the launch of all Minuteman ICBMs.
